Drug Summary

What Is Toradol?

Toradol (ketorolac tromethamine) is a nonsteroidal anti-inflammatory drug (NSAID) that is used to treat moderately severe pain and inflammation, usually after surgery. Toradol works by blocking the production of prostaglandins, compounds that cause pain, fever, and inflammation. The brand name Toradol is no longer available in the U.S.Genericversions may be available.

What Are Side Effects of Toradol?

Common side effects of Toradol include:

  • headache,
  • heartburn,
  • upset stomach,
  • nausea,
  • vomiting,
  • diarrhea,
  • stomach pain,
  • bloating,
  • gas,
  • constipation,
  • dizziness,
  • drowsiness,
  • sweating,
  • andringing in the ears

Dosage for Toradol

Toradol is available as a 10 mg tablet and a solution (30 mg per ml) for intravenous (IV) orintramuscular(IM) administration. Toradol solution is administered as a single 15- to 60-mg dose once every 6 hours not to exceed 60 or 120 mg a day. The recommended oral dose is one to two Toradol tablets initially followed by one tablet every 4-6 hours, not to exceed 40 mg daily. Toradol should not be used for more than 5 days.

What Drugs, Substances, or Supplements Interact with Toradol?

Drug interactions may occur withlithium,ACE inhibitors, warfarin, and medications used to treat highuric acidlevels. Warnings may apply to individuals who have ulcers,cardiovascular disease, kidney disease, and bleeding disorders. People who are takingaspirinor NSAIDs should not take Toradol because of the cumulative risk of inducing serious NSAID-related side effects.

Toradol During Pregnancy and Breastfeeding

Toradol is generally avoided during pregnancy. Pregnant women may take Toradol only if it is clearly needed and the potential benefit justifies the potential risk to the fetus. Nursing mothers should not take Toradol, because it is excreted in breast milk. Toradol solution may be used as a single dose in children in certain instances, but safety and effectiveness in the pediatric population is not established.

Drug Description

WARNING

TORADOLORAL(ketorolac tromethamine), a nonsteroidal anti-inflammatory drug (NSAID), is indicated for the short-term (up to 5 days in adults), management of moderately severe acute pain that requires analgesia at the opioid level and only as continuation treatment following IV or IM dosing of ketorolac tromethamine, if necessary. The total combined duration of use of TORADOLORALand ketorolac tromethamine should not exceed 5 days.

TORADOL (ketorolac tromethamine)ORALis not indicated for use in pediatric patients and it is NOT indicated for minor or chronic painful conditions. Increasing the dose of TORADOL (ketorolac tromethamine)ORALbeyond a daily maximum of 40 mg in adults will not provide better efficacy but will increase the risk of developing serious adverse events.

GASTROINTESTINAL RISK

  • Ketorolac tromethamine, including TORADOL (ketorolac tromethamine) can cause peptic ulcers,gastrointestinalbleeding and/or perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Therefore, TORADOL (ketorolac tromethamine) is CONTRAINDICATED in patients with activepeptic ulcerdisease, in patients with recent gastrointestinal bleeding or perforation, and in patients with a history of peptic ulcer disease or gastrointestinal bleeding. Elderly patients are at greater risk for serious gastrointestinal events (seeWARNINGS).

CARDIOVASCULAR RISK

  • NSAIDs may cause an increased risk of seriouscardiovascularthrombotic events,myocardial infarction, andstroke, which can be fatal. This risk may increase with duration of use. Patients withcardiovascular diseaseor risk factors for cardiovascular disease may be at greater risk (seeWARNINGSandCLINICAL TRIALS).
  • TORADOL (ketorolac tromethamine) is CONTRAINDICATED for the treatment ofperi-operative pain in the setting of coronary arterybypassgraft (CABG) surgery (seeWARNINGS).

RENAL RISK

  • TORADOL (ketorolac tromethamine) is CONTRAINDICATED in patients with advanced renal impairment and in patients at risk for renal failure due to volume depletion (seeWARNINGS).

RISK OF BLEEDING

TORADOL (ketorolac tromethamine) is CONTRAINDICATED as prophylactic analgesic before any major surgery.

RISK DURING LABOR AND DELIVERY

  • The use of TORADOL (ketorolac tromethamine) in labor and delivery is contraindicated because it may adversely affectfetal circulationand inhibit uterine contractions. The use of TORADOL (ketorolac tromethamine) is contraindicated in nursing mothers because of the potential adverse effects ofprostaglandin-inhibiting drugs on neonates.

CONCOMITANT USE WITH NSAIDS

  • TORADOL (ketorolac tromethamine) is CONTRAINDICATED in patients currently receiving aspirin or NSAIDs because of the cumulative risk of inducing seriousNSAID-related side effects.

特殊人群

Dosage should be adjusted for patients 65 years or older, for patients under 50 kg (110 lbs) of body weight (seeDOSAGE AND ADMINISTRATION) and for patients with moderately elevated serum creatinine (seeWARNINGS).

Postmarketing Surveillance Study

A large postmarketing observational, nonrandomized study, involving approximately 10,000 patients receiving ketorolac tromethamineIV/IM, demonstrated that the risk of clinically serious gastrointestinal (GI) bleeding was dose-dependent (see Tables 3A and 3B). This was particularly true in elderly patients who received an average daily dose greater than 60 mg/day of ketorolac tromethamineIV/IM(see Table 3A).

Drug Interactions

DRUG INTERACTIONS

Ketorolac is highly bound to human plasma protein (mean 99.2%). There is no evidence in animal or human studies that TORADOL (ketorolac tromethamine) induces or inhibits hepatic enzymes capable of metabolizing itself or other drugs.

Warfarin, Digoxin, Salicylate, and Heparin

The in vitro binding ofwarfarinto plasma proteins is only slightly reduced by ketorolac tromethamine (99.5% control vs 99.3%) when ketorolac plasma concentrations reach 5 to 10 μg/mL. Ketorolac does not alterdigoxinprotein binding. In vitro studies indicate that, at therapeutic concentrations ofsalicylate(300 μg/mL), the binding of ketorolac was reduced from approximately 99.2% to 97.5%, representing a potential twofold increase in unbound ketorolac plasma levels. Therapeutic concentrations ofdigoxin, warfarin, ibuprofen, naproxen, piroxicam, acetaminophen, phenytoinandtolbutamidedid not alter ketorolac tromethamine protein binding.

In a study involving 12 adult volunteers, TORADOL (ketorolac tromethamine)ORALwas coadministered with a single dose of 25 mgwarfarin, causing no significant changes in pharmacokinetics or pharmacodynamics of warfarin. In another study, ketorolac tromethamine dosed IV or IM was given with two doses of 5000 U ofheparinto 11 healthy volunteers, resulting in a mean template bleeding time of 6.4 minutes (3.2 to 11.4 min) compared to a mean of 6.0 minutes (3.4 to 7.5 min) forheparinalone and 5.1 minutes (3.5 to 8.5 min) for placebo. Although these results do not indicate a significant interaction between TORADOL (ketorolac tromethamine) and warfarin or heparin, the administration of TORADOL (ketorolac tromethamine) to patients taking anticoagulants should be done extremely cautiously, and patients should be closely monitored (seeWARNINGSandPRECAUTIONS: Hematologic Effect).

The effects of warfarin and NSAIDs, in general, on GI bleeding are synergistic, such that the users of both drugs together have a risk of serious GI bleeding higher than the users of either drug alone.

Aspirin

When TORADOL (ketorolac tromethamine) is administered with aspirin, its protein binding is reduced, although the clearance of free TORADOL (ketorolac tromethamine) is not altered. The clinical significance of this interaction is not known; however, as with other NSAIDs, concomitant administration of ketorolac tromethamine and aspirin is not generally recommended because of the potential of increased adverse effects.

Diuretics

Clinical studies, as well as postmarketing observations, have shown that TORADOL (ketorolac tromethamine) can reduce thenatriureticeffect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure (seeWARNINGS: Renal Effects), as well as to assurediureticefficacy.

Probenecid

Concomitant administration of TORADOL (ketorolac tromethamine)ORALandprobenecidresulted in decreased clearance and volume of distribution of ketorolac and significant increases in ketorolac plasma levels (total AUC increased approximately threefold from 5.4 to 17.8 μg/h/mL) and terminal half-life increased approximately twofold from 6.6 to 15.1 hours. Therefore, concomitant use of TORADOL (ketorolac tromethamine) and probenecid is contraindicated.

Lithium

NSAIDs have produced an elevation of plasmalithiumlevels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity.

Methotrexate

NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate.

ACE Inhibitors/Angiotension II Receptor Antagonists

Concomitant use ofACE inhibitorsand/or angiotension II receptor antagonistsmay increase the risk of renal impairment, particularly in volume-depleted patients.

Reports suggest that NSAIDs may diminish theantihypertensiveeffect of ACE inhibitors and/or angiotension II receptor antagonists. This interaction should be given consideration in patients taking NSAIDs concomitantly withACE inhibitorsand/or angiotension II receptor antagonists.

Antiepileptic Drugs

Sporadic在concom癫痫病例报告itant use of TORADOL (ketorolac tromethamine) andantiepileptic drugs(phenytoin, carbamazepine).

Psychoactive Drugs

Hallucinations have been reported when TORADOL (ketorolac tromethamine) was used in patients takingpsychoactive drugs(fluoxetine, thiothixene,alprazolam).

Pentoxifylline

When ketorolac tromethamine is administered concurrently with pentoxifylline, there is an increased tendency to bleeding.

Nondepolarizing Muscle Relaxants

In postmarketing experience there have been reports of a possible interaction between ketorolac tromethamineIV/IMandnondepolarizing muscle relaxantsthat resulted inapnea.The concurrent use of ketorolac tromethamine with muscle relaxants has not been formally studied.

Selective Serotonin Reuptake Inhibitors (SSRIs)

There is an increased risk of gastrointestinal bleeding when selectiveserotoninreuptakeinhibitors (SSRIs) are combined with NSAIDs. Caution should be used when NSAIDs are administered concomitantly with SSRIs.

Warnings

WARNINGS

(见也BOXED WARNING)

The total combined duration of use of TORADOLORALand IV or IM dosing of ketorolac tromethamine is not to exceed 5 days in adults. TORADOL (ketorolac tromethamine)ORALis not indicated for use in pediatric patients.

The most serious risks associated with TORADOL (ketorolac tromethamine) are:

Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation

TORADOL (ketorolac tromethamine) is contraindicated in patients with previously documented peptic ulcers and/or GI bleeding. Toradol (ketorolac tromethamine) can cause serious gastrointestinal (GI) adverse events including bleeding, ulceration and perforation, of the stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with TORADOL (ketorolac tromethamine) .

只有五分之一的病人患上严重的per GI adverse event on NSAID therapy is symptomatic. Minor upper gastrointestinal problems, such as dyspepsia, are common and may also occur at any time during NSAID therapy. The incidence and severity of gastrointestinal complications increases with increasing dose of, and duration of treatment with, TORADOL (ketorolac tromethamine) . Do not use TORADOL (ketorolac tromethamine) for more than five days. However, even short-term therapy is not without risk. In addition to past history of ulcer disease, other factors that increase the risk for GI bleeding in patients treated with NSAIDs include concomitant use of oral corticosteroids, or anticoagulants, longer duration of NSAID therapy, smoking, use of alcohol, older age, and poor general health status. Most spontaneous reports of fatal GI events are in elderly or debilitated patients and therefore, special care should be taken in treating this population.

To minimize the potential risk for an adverse GI event, the lowest effective dose should be used for the shortest possible duration.Patients and physicians should remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. This should include discontinuation of TORADOL (ketorolac tromethamine) until a serious GI adverse event is ruled out. For high risk patients, alternate therapies that do not involve NSAIDs should be considered.

NSAIDs should be given with care to patients with a history of inflammatory bowel disease (ulcerativecolitis, Crohn's disease) as their condition may be exacerbated.

Hemorrhage

Because prostaglandins play an important role in hemostasis and NSAIDs affectplatelet aggregationas well, use of TORADOL (ketorolac tromethamine) in patients who havecoagulationdisorders should be undertaken very cautiously, and those patients should be carefully monitored. Patients on therapeutic doses of anticoagulants (eg, heparin or dicumarol derivatives) have an increased risk of bleeding complications if given TORADOL (ketorolac tromethamine) concurrently; therefore, physicians should administer such concomitant therapy only extremely cautiously. The concurrent use of TORADOL (ketorolac tromethamine) and therapy that affects hemostasis, includingprophylacticlow-dose heparin (2500 to 5000 units q12h), warfarin and dextrans have not been studied extensively, but may also be associated with an increased risk of bleeding. Until data from such studies are available, physicians should carefully weigh the benefits against the risks and use such concomitant therapy in these patients only extremely cautiously. Patients receiving therapy that affects hemostasis should be monitored closely.

In postmarketing experience, postoperative hematomas and other signs of wound bleeding have been reported in association with the peri-operative use of IV or IM dosing of ketorolac tromethamine. Therefore, peri-operative use of TORADOL (ketorolac tromethamine) should be avoided and postoperative use be undertaken with caution when hemostasis is critical (seePRECAUTIONS).

Renal Effects

Long-term administration of NSAIDs has resulted in renal papillarynecrosisand other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renalperfusion.在这些患者中,政府的非甾体抗炎药cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function,heart failure, liver dysfunction, those taking diuretics and ACE inhibitors, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state.

TORADOL (ketorolac tromethamine) and its metabolites are eliminated primarily by the kidneys, which, in patients with reduced creatinine clearance, will result in diminished clearance of the drug (seeCLINICAL PHARMACOLOGY). Therefore, TORADOL (ketorolac tromethamine) should be used with caution in patients with impaired renal function (seeDOSAGE AND ADMINISTRATION) and such patients should be followed closely. With the use of TORADOL (ketorolac tromethamine) , there have been reports ofacute renal failure, interstitial nephritis and nephrotic syndrome.

Impaired Renal Function

TORADOL (ketorolac tromethamine)iscontraindicated in patients with serum creatinine concentrations indicating advanced renal impairment(seeCONTRAINDICATIONS). TORADOL (ketorolac tromethamine) should be used with caution in patients with impaired renal function or a history of kidney disease because it is a potent inhibitor of prostaglandin synthesis. Because patients with underlying renal insufficiency are at increased risk of developing acute renal decompensation or failure, the risks and benefits should be assessed prior to giving TORADOL (ketorolac tromethamine) to these patients.

Anaphylactoid Reactions

As with other NSAIDs, anaphylactoid reactions may occur in patients without a known previous exposure or hypersensitivity to TORADOL (ketorolac tromethamine) . TORADOL (ketorolac tromethamine) should not be given to patients with the aspirin triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or withoutnasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs (seeCONTRAINDICATIONSandPRECAUTIONS: Preexisting Asthma). Anaphylactoid reactions, like anaphylaxis, may have a fatal outcome. Emergency help should be sought in cases where an anaphylactoid reaction occurs.

Cardiovascular Effects

Cardiovascular Thrombotic Events

Clinical trials of severalCOX-2selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. All NSAIDs, both COX-2 selective and nonselective, may have a similar risk. Patients with known CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of such events, even in the absence of previous CV symptoms. Patients should be informed about the signs and/or symptoms of serious CV events and the steps to take if they occur.

There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID does increase the risk of serious GI events (seeGastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation). Two large, controlled clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10-14 days following CABG surgery found an increased incidence of myocardial infarction and stroke (seeCONTRAINDICATIONS).

Hypertension

NSAIDs, including TORADOL (ketorolac tromethamine) , can lead to onset of new hypertension or worsening of preexisting hypertension, either of which may contribute to the increased incidence of CV events. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs. NSAIDs, including TORADOL (ketorolac tromethamine) , should be used with caution in patients with hypertension. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy.

Congestive Heart Failure and Edema

Fluid retention, edema, retention of NaCl, oliguria, elevations of serumureanitrogen and creatinine have been reported in clinical trials with TORADOL (ketorolac tromethamine) . Therefore, TORADOL (ketorolac tromethamine) should be used only very cautiously in patients with cardiac decompensation, hypertension or similar conditions.

Skin Reactions

NSAIDS, including TORADOL (ketorolac tromethamine) , can cause seriousskin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxicepidermalnecrolysis (TEN), which can be fatal. These serious events may occur without warning. Patients should beinformed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash, mucosal lesions, or any other sign of hypersensitivity.

Pregnancy

In late pregnancy, as with other NSAIDs, TORADOL (ketorolac tromethamine) should be avoided because it may cause premature closure of the ductus arteriosus.

Precautions

PRECAUTIONS

General

TORADOL (ketorolac tromethamine) cannot be expected to substitute for corticosteroids or to treatcorticosteroidinsufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids.

The pharmacological activity of TORADOL (ketorolac tromethamine) in reducing inflammation may diminish the utility of this diagnostic sign in detecting complications of presumed noninfectious, painful conditions.

Hepatic Effect

TORADOL (ketorolac tromethamine) should be used with caution in patients with impaired hepatic function or a history ofliver disease.肝脏边缘地区的一个或多个测试may occur in up to 15% of patients taking NSAIDs including TORADOL (ketorolac tromethamine) . These laboratory abnormalities may progress, may remain unchanged, or may be transient with continuing therapy. Notable elevations of ALT or AST (approximately three or more times the upper limit of normal) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In addition, rare cases of severe hepatic reactions, including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic failure, some of them with fatal outcomes have been reported.

A patient with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred, should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with TORADOL (ketorolac tromethamine) . If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (eg, eosinophilia, rash, etc.), TORADOL (ketorolac tromethamine) should be discontinued.

Hematologic Effect

Anemia is sometimes seen in patients receiving NSAIDs, including TORADOL (ketorolac tromethamine) . This may be due to fluid retention,occultor gross GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including TORADOL (ketorolac tromethamine) , should have theirhemoglobinorhematocritchecked if they exhibit any signs or symptoms of anemia. NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Unlike aspirin, their effect on platelet function is quantitatively less, of shorter duration, and reversible. Patients receiving TORADOL (ketorolac tromethamine) who may be adversely affected by alterations in platelet function, such as those with coagulation disorders or patients receiving anticoagulants, should be carefully monitored.

Preexisting Asthma

哮喘患者可能aspirin-sensitivethma. The use of aspirin in patients with aspirin-sensitive asthma has been associated with severe bronchospasm which can be fatal. Since cross reactivity, including bronchospasm, between aspirin and other nonsteroidal anti-inflammatory drugs has been reported in such aspirin-sensitive patients, TORADOL (ketorolac tromethamine) should not be administered to patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma.

Information for Patients

TORADOL (ketorolac tromethamine) is a potent NSAID and may cause serious side effects such as gastrointestinal bleeding or kidney failure, which may result in hospitalization and even fatal outcome.

Physicians, when prescribing TORADOL (ketorolac tromethamine) , should inform their patients or their guardians of the potential risks of TORADOL treatment (seeBOXED WARNING,WARNINGS,PRECAUTIONS, andADVERSE REACTIONSsections), instruct patients to seek medical advice if they develop treatment-related adverse events, andadvise patients not to give TORADOL (ketorolac tromethamine)ORALto other family members and to discard any unused drug.

Remember that the total combined duration of use of TORADOLORALand IV or IM dosing of ketorolac tromethamine is not to exceed 5 days in adults. TORADOL (ketorolac tromethamine)ORALis not indicated for use in pediatric patients.

患者应该被告知以下公司mation before initiating therapy with an NSAID and periodically during the course of ongoing therapy. Patients should also be encouraged to read the NSAIDMedication Guidethat accompanies each prescription dispensed.

  1. TORADOL (ketorolac氨丁三醇),像其他NSAIDs, may cause serious CV side effects, such as MI or stroke, which may result in hospitalization and even death. Although serious CV events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and should ask for medical advice when observing any indicative sign or symptoms. Patients should be apprised of the importance of this follow-up (seeWARNINGS: Cardiovascular Effects).
  2. TORADOL (ketorolac氨丁三醇),像其他NSAIDs, can cause GI discomfort and rarely, serious GI side effects, such as ulcers and bleeding, which may result in hospitalization and even death. Although serious GI tract ulcerations and bleeding can occur without warning symptoms, patients should be alert for the signs and symptoms of ulcerations and bleeding, and should ask for medical advice when observing any indicative sign or symptoms including epigastric pain, dyspepsia, melena, and hematemesis. Patients should be apprised of the importance of this follow-up (seeWARNINGS: Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation).
  3. TORADOL (ketorolac氨丁三醇),像其他NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, SJS, and TEN, which may result in hospitalizations and even death. Although serious skin reactions may occur without warning, patients should be alert for the signs and symptoms of skin rash and blisters, fever, or other signs of hypersensitivity such as itching, and should ask for medical advice when observing any indicative signs or symptoms. Patients should be advised to stop the drug immediately if they develop any type of rash and contact their physicians as soon as possible.
  4. Patients should promptly report signs or symptoms of unexplained weight gain or edema to their physicians.
  5. Patients should be informed of the warning signs and symptoms of hepatotoxicity (eg, nausea, fatigue,lethargy, pruritus, jaundice, right upperquadranttenderness, and “flu-like” symptoms). If these occur, patients should be instructed to stop therapy and seek immediate medical therapy.
  6. Patients should be informed of the signs of an anaphylactoid reaction (eg, difficulty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek immediate emergency help (seeWARNINGS).
  7. In late pregnancy, as with other NSAIDs, TORADOL (ketorolac tromethamine) should be avoided because it will cause premature closure of the ductus arteriosus.

Laboratory Tests

Because serious GI tract ulcerations and bleeding can occur without warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. Patients on long-term treatment with NSAIDs, should have theirCBCand a chemistry profile checked periodically. If clinical signs and symptoms consistent with liver or renal disease develop, systemic manifestations occur (eg, eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, TORADOL (ketorolac tromethamine) should be discontinued.

Carcinogenesis, Mutagenesis and Impairment of Fertility

An 18-month study in mice with oral doses of ketorolac tromethamine at 2 mg/kg/day (0.9 times the human systemic exposure at the recommended IM or IV dose of 30 mg qid, based on area-under-the-plasma-concentration curve [AUC]), and a 24-month study in rats at 5 mg/kg/day (0.5 times the human AUC) showed no evidence of tumorigenicity. Ketorolac tromethamine was not mutagenic in the Ames test, unscheduled DNA synthesis and repair, and in forward mutation assays.

Ketorolac tromethamine did not cause chromosome breakage in the in vivo mouse micronucleus assay. At 1590 μg/mL and at higher concentrations, ketorolac tromethamine increased the incidence of chromosomal aberrations in Chinese hamster ovarian cells.

Impairment of fertility did not occur in male or female rats at oral doses of 9 mg/kg (0.9 times the human AUC) and 16 mg/kg (1.6 times the human AUC) of ketorolac tromethamine, respectively.

Pregnancy

Teratogenic Effects: Pregnancy Category C

Reproduction studies have been performed during organogenesis using daily oral doses of ketorolac tromethamine at 3.6 mg/kg (0.37 times the human AUC) in rabbits and at 10 mg/kg (1.0 times the human AUC) in rats. Results of these studies did not reveal evidence of teratogenicity to the fetus. However, animal reproduction studies are not always predictive of human response.

Nonteratogenic Effects

Because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly late pregnancy) should be avoided. Oral doses of ketorolac tromethamine at 1.5 mg/kg (0.14 times the human AUC), administered after gestation Day 17, caused dystocia and higher pup mortality in rats.

没有足够的、严谨的研究报告of TORADOL (ketorolac tromethamine) in pregnant women. TORADOL (ketorolac tromethamine) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Labor and Delivery

The use of TORADOL (ketorolac tromethamine) is contraindicated in labor and delivery because, through its prostaglandin synthesis inhibitory effect, it may adversely affect fetalcirculationand inhibit uterine contractions, thus increasing the risk of uterine hemorrhage (seeCONTRAINDICATIONS).

Effects on Fertility

The use of ketorolac tromethamine, as with any drug known to inhibit cyclooxygenase/prostaglandin synthesis, may impair fertility and is not recommended in women attempting to conceive. In women who have difficulty conceiving or are undergoing investigation of infertility, withdrawal of ketorolac tromethamine should be considered.

Nursing Mothers

After a single administration of 10 mg of TORADOL (ketorolac tromethamine)ORALto humans, the maximum milk concentration observed was 7.3 ng/mL, and the maximum milk-to-plasma ratio was 0.037. After 1 day of dosing (qid), the maximum milk concentration was 7.9 ng/mL, and the maximum milk-to-plasma ratio was 0.025. Because of the possible adverse effects of prostaglandin-inhibiting drugs on neonates, use in nursing mothers is contraindicated.

Pediatric Use

TORADOL (ketorolac tromethamine)ORALis not indicated for use in pediatric patients. The safety and effectiveness of TORADOL (ketorolac tromethamine)ORALin pediatric patients below the age of 17 have not been established.

Geriatric Use ( ≥ 65 years of age)

Because ketorolac tromethamine may be cleared more slowly by the elderly (seeCLINICAL PHARMACOLOGY) who are also more sensitive to the dose-related adverse effects of NSAIDs (seeWARNINGS: Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation), extreme caution, reduced dosages (seeDOSAGE AND ADMINISTRATION), and careful clinical monitoring must be used when treating the elderly with TORADOL (ketorolac tromethamine) .

Overdose

OVERDOSE

Symptoms and Signs

Symptoms following acute NSAID overdoses are usually limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain, which are generally reversible with supportive care. Gastrointestinal bleeding can occur. Hypertension, acute renal failure, respiratory depression and coma may occur, but are rare. Anaphylactoid reactions have been reported with therapeutic ingestion of NSAIDs, and may occur following an overdose.

Treatment

Patients should be managed by symptomatic andsupportive carefollowing a NSAIDs overdose. There are no specific antidotes.Emesisand/oractivated charcoal(60 g to 100 g in adults, 1 g/kg to 2 g/kg in children) and/or osmotic cathartic may be indicated in patients seen within 4 hours of ingestion with symptoms or following a large oral overdose (5 to 10 times the usual dose). Forceddiuresis, alkalization of urine,hemodialysisor hemoperfusion may not be useful due to high protein binding. Single overdoses of TORADOL have been variously associated with abdominal pain, nausea, vomiting, hyperventilation, peptic ulcers and/or erosive gastritis and renal dysfunction which have resolved after discontinuation of dosing.

Contraindications

CONTRAINDICATIONS

TORADOL is contraindicated in patients with previously demonstrated hypersensitivity to ketorolac tromethamine.

TORADOL is contraindicated in patients with active peptic ulcer disease, in patients with recent gastrointestinal bleeding or perforation and in patients with a history of peptic ulcer disease or gastrointestinal bleeding.

TORADOL should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients (see WARNINGS: Anaphylactoid Reactions, and PRECAUTIONS: Preexisting Asthma).

TORADOL is contraindicated as prophylacticanalgesicbefore any major surgery.

TORADOL is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS).

TORADOL is contraindicated in patients with advanced renal impairment or in patients at risk for renal failure due to volume depletion (see WARNINGS for correction of volume depletion).

TORADOL is contraindicated in labor and delivery because, through its prostaglandin synthesis inhibitory effect, it may adversely affect fetal circulation and inhibit uterine contractions, thus increasing the risk of uterine hemorrhage.

TORADOL inhibits platelet function and is, therefore, contraindicated in patients with suspected or confirmed cerebrovascular bleeding, hemorrhagic diathesis, incomplete hemostasis and those at high risk of bleeding (see WARNINGS and PRECAUTIONS).

TORADOL is contraindicated in patients currently receiving aspirin or NSAIDs because of the cumulative risks of inducing serious NSAID-related adverse events.

The concomitant use of TORADOL and probenecid is contraindicated.

The concomitant use of ketorolac tromethamine and pentoxifylline is contraindicated.

ClinicalPharmacology

CLINICAL PHARMACOLOGY

Pharmacodynamics

Ketorolac tromethamine is a nonsteroidal anti-inflammatory drug (NSAID) that exhibits analgesic activity in animal models. The mechanism of action of ketorolac, like that of other NSAIDs, is not completely understood but may be related to prostaglandin synthetase inhibition. The biological activity of ketorolac tromethamine is associated with the S-form. Ketorolac tromethamine possesses nosedativeor anxiolytic properties.

The peak analgesic effect of TORADOL (ketorolac tromethamine) occurs within 2 to 3 hours and is not statistically significantly different over the recommended dosage range of TORADOL (ketorolac tromethamine) . The greatest difference between large and small doses of TORADOL (ketorolac tromethamine) is in the duration of analgesia.

Pharmacokinetics

Ketorolac tromethamine is a racemic mixture of [-]S- and [+]R-enantiomeric forms, with the S-form having analgesic activity.

Comparison of IV, IM and Oral Pharmacokinetics

The pharmacokinetics of ketorolac tromethamine, following IV and IM doses of ketorolac tromethamine and oral doses of TORADOL (ketorolac tromethamine) , are compared inTable 1.In adults, the extent of bioavailability following administration of the ORAL form of TORADOL and the IM form of ketorolac tromethamine was equal to that following an IV bolus.

Linear Kinetics

In adults, following administration of single ORAL doses of TORADOL or IM or IV doses of ketorolac tromethamine in the recommended dosage ranges, the clearance of the racemate does not change. This implies that the pharmacokinetics of ketorolac tromethamine in adults, following single or multiple IM or IV doses of ketorolac tromethamine or recommended oral doses of TORADOL (ketorolac tromethamine) , are linear. At the higher recommended doses, there is a proportional increase in the concentrations of free and bound racemate.

Absorption

TORADOL (ketorolac tromethamine) is 100% absorbed after oral administration (seeTable 1). Oral administration of TORADOL (ketorolac tromethamine) after a high-fat meal resulted in decreased peak and delayed time-to-peak concentrations of ketorolac tromethamine by about 1 hour. Antacids did not affect the extent of absorption.

Distribution

The mean apparent volume (Vβ) of ketorolac tromethamine following complete distribution was approximately 13 liters. This parameter was determined from single-dose data. The ketorolac tromethamine racemate has been shown to be highly protein bound (99%). Nevertheless, plasma concentrations as high as 10 μg/mL will only occupy approximately 5% of thealbuminbinding sites. Thus, the unbound fraction for each enantiomer will be constant over the therapeutic range. A decrease in serum albumin, however, will result in increased free drug concentrations.

Ketorolac tromethamine is excreted in human milk (seePRECAUTIONS: Nursing Mothers).

Metabolism

Ketorolac tromethamine is largely metabolized in the liver. The metabolic products are hydroxylated and conjugated forms of the parent drug. The products ofmetabolism, and some unchanged drug, are excreted in the urine.

Excretion

The principal route of elimination of ketorolac and its metabolites is renal. About 92% of a given dose is found in the urine, approximately 40% as metabolites and 60% as unchanged ketorolac. Approximately 6% of a dose is excreted in the feces. A single-dose study with 10 mg TORADOL (ketorolac tromethamine) (n=9) demonstrated that the S-enantiomer is cleared approximately two times faster than the R-enantiomer and that the clearance was independent of the route of administration. This means that the ratio of S/R plasma concentrations decreases with time after each dose. There is little or no inversion of the R- to S- form in humans. The clearance of the racemate in normal subjects, elderly individuals and in hepatically and renally impaired patients is outlined inTable 2(seeCLINICAL PHARMACOLOGY: Kinetics in Special Populations).

The half-life of the ketorolac tromethamine S-enantiomer was approximately 2.5 hours (SD ± 0.4) compared with 5 hours (SD ± 1.7) for the R-enantiomer. In other studies, the half-life for the racemate has been reported to lie within the range of 5 to 6 hours.

Accumulation

Ketorolac tromethamine administered as an IV bolus every 6 hours for 5 days to healthy subjects (n=13), showed no significant difference in Cmax on Day 1 and Day 5. Trough levels averaged 0.29 μg/mL (SD ± 0.13) on Day 1 and 0.55 μg/mL (SD ± 0.23) on Day 6. Steady state was approached after the fourth dose. Accumulation of ketorolac tromethamine has not been studied in special populations (geriatric, pediatric, renal failure or hepatic disease patients).

Kinetics in Special Populations

Geriatric Patients

Based on single-dose data only, the half-life of the ketorolac tromethamine racemate increased from 5 to 7 hours in the elderly (65 to 78 years) compared with young healthy volunteers (24 to 35 years) (seeTable 2). There was little difference in the Cmax for the two groups (elderly, 2.52 μg/mL ± 0.77; young, 2.99 μg/mL ± 1.03) (seePRECAUTIONS: Geriatric Use).

Pediatric Patients

Limited information is available regarding the pharmacokinetics of dosing of ketorolac tromethamine in the pediatric population. Following a single intravenous bolus dose of 0.5 mg/kg in 10 children 4 to 8 years old, the half-life was 5.8 ± 1.6 hours, the average clearance was 0.042 ± 0.01 L/hr/kg, the volume of distribution during the terminal phase (Vβ) was 0.34 ± 0.12 L/kg and the volume of distribution at steady state (Vss) was 0.26 ± 0.08 L/kg. The volume of distribution and clearance of ketorolac in pediatric patients was higher than those observed in adult subjects (seeTable 1). There are no pharmacokinetic data available for administration of ketorolac tromethamine by the IM route in pediatric patients.

Renal Insufficiency

Based on single-dose data only, the mean half-life of ketorolac tromethamine in renally impaired patients is between 6 and 19 hours and is dependent on the extent of the impairment. There is poor correlation between creatinine clearance and total ketorolac tromethamine clearance in the elderly and populations with renal impairment (r=0.5).

In patients with renal disease, the AUC∞ of each enantiomer increased by approximately 100% compared with healthy volunteers. The volume of distribution doubles for the S-enantiomer and increases by 1/5th for the R-enantiomer. The increase in volume of distribution of ketorolac tromethamine implies an increase in unbound fraction.

The AUC∞ -ratio of the ketorolac tromethamine enantiomers in healthy subjects and patients remained similar, indicating there was no selective excretion of either enantiomer in patients compared to healthy subjects (seeWARNINGS: Renal Effects).

Hepatic Insufficiency

There was no significant difference in estimates of half-life, AUC∞ and Cmax in 7 patients with liver disease compared to healthy volunteers (seePRECAUTIONS: Hepatic EffectandTable 2).

Race

Pharmacokinetic differences due to race have not been identified.

Clinical studies

Adult Patients

In a postoperative study, where all patients receivedmorphineby aPCAdevice, patients treated with ketorolac tromethamineIVas fixed intermittent boluses (e.g., 30 mg initial dose followed by 15 mg q3h), required significantly less morphine (26%) than the placebo group. Analgesia was significantly superior, at various postdosing pain assessment times, in the patients receiving ketorolac tromethamineIVplus PCA morphine as compared to patients receiving PCA-administered morphine alone.

Pediatric Patients

There are no data available to support the use of TORADOL (ketorolac tromethamine)ORALin pediatric patients.

Medication Guide

PATIENT INFORMATION

MEDICATION GUIDE FOR NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS)
(See the end of this Medication Guide for a list of prescription NSAID medicines.)

What is the most important information I should know about medicines called Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)?

NSAID medicines may increase the chance of a heart attack or stroke that can lead to death.This chance increases:

  • with longer use of NSAID medicines
  • in people who haveheart disease

NSAID medicines should never be used right before or after a heart surgery called a “coronary artery bypass graft (CABG).”

NSAID medicines can cause ulcers and bleeding in the stomach and intestines at any time during treatment. Ulcers and bleeding:

  • can happen without warning symptoms
  • may cause death

The chance of a person getting an ulcer or bleeding increases with:

  • taking medicines called “corticosteroids” and “anticoagulants”
  • longer use
  • smoking
  • drinking alcohol
  • older age
  • having poor health

NSAID medicines should only be used:

  • exactly as prescribed
  • at the lowest dose possible for your treatment
  • for the shortest time needed

What are Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)?

NSAID medicines are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as:

Who should not take a Nonsteroidal Anti-Inflammatory Drug (NSAID)?

Do not take an NSAID medicine:

  • if you had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAID medicine
  • for pain right before or after heart bypass surgery

Tell your healthcare provider:

  • about all of your medical conditions.
  • 关于你所有的药物。非甾体抗炎药,所以me other medicines can interact with each other and cause serious side effects.Keep a list of your medicines to show to your healthcare provider and pharmacist.
  • if you are pregnant.NSAID medicines should not be used by pregnant women late in their pregnancy.
  • if you are breastfeeding. Talk to your doctor.

What are the possible side effects of Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)?

Serious side effects include:
• heart attack
• stroke
• high blood pressure
• heart failure from body swelling (fluid
retention)
• kidney problems including kidney failure
• bleeding and ulcers in the stomach and
intestine
• low red blood cells (anemia)
• life-threatening skin reactions
• life-threatening allergic reactions
• liver problems including liver failure
• asthma attacks in people who have asthma

Other side effects include:
• stomach pain
• constipation
• diarrhea
• gas
• heartburn
• nausea
• vomiting
• dizziness

如果y马上紧急援助ou have any of the following symptoms:

  • shortness of breath or trouble breathing
  • chest pain
  • weakness in one part or side of your body
  • slurred speech
  • swelling of the face or throat

Stop your NSAID medicine and call your healthcare provider right away if you have any of the following symptoms:

  • nausea
  • 比平时更累或较弱
  • itching
  • your skin or eyes look yellow
  • stomach pain
  • flu-like symptoms
  • vomitblood
  • there is blood in your bowel movement or it is black and sticky like tar
  • unusual weight gain
  • skin rash or blisters with fever
  • swelling of the arms and legs, hands and feet

These are not all the side effects with NSAID medicines. Talk to your healthcare provider or pharmacist for more information about NSAID medicines.

Other information about Nonsteroidal Anti-Inflammatory Drugs (NSAIDs):

  • Aspirin is an NSAID medicine but it does not increase the chance of a heart attack. Aspirin can cause bleeding in the brain, stomach, and intestines. Aspirin can also cause ulcers in the stomach and intestines.
  • Some of these NSAID medicines are sold in lower doses without a prescription (over-the-counter). Talk to your healthcare provider before using over-the-counter NSAIDs for more than 10 days.
