How Do Anticholinergic Agents Work?

Anticholinergicagents are a class of medications used to treat variousgastrointestinal,bladder, and bowel control problems, kidney stones, and gall stones. Anticholinergics are drugs that block the action of “acetylcholine.” Acetylcholine is aneurotransmitter(a chemical messenger) released by the nerves for the contraction of muscles. Blocking of acetylcholine inhibitsinvoluntarymuscle movements and various other bodily functions.

These are administered via oral and intravenous routes.

Anticholinergic agents work in the following ways:

• 他们的提单ock the action of a neurotransmitter called “acetylcholine” in the central and peripheral nervous systems.
• Acetylcholine is responsible for transferring signals between certain cells that perform specific bodily functions (including digestion, urination, salivation).
• 他们的提单ock acetylcholine from binding to its receptors on certain nerve cells which inhibits involuntary muscle movements in thelungs,gastrointestinal tract,尿路, and other areas of the body.
• Anticholinergic agents decrease the acid production in the stomach that slows down the natural gut movements, thus relaxing the muscles in several organs such as the stomach, intestines, kidney, and bladder.
• In addition, they decrease the amount of body fluids (saliva, sweat).

Anticholinergic agents are used for the following:

• Gastrointestinal disorders
  • Peptic ulcerdisease (sores that develop in the lining of the stomach, loweresophagus, orsmall intestine)
  • Irritable bowel syndrome(an intestinal disorder causing pain in the stomach, diarrhea and constipation)
  • Abdominal cramps
  • Diverticulitis(small,bulgingpouches that can form in the lining of thedigestive system)
• Cramping pain caused by:
  • Kidney stones
  • Gall stones
• Side effects of certain medications such as:
  • Drugs used to treatmyasthenia gravis
  • Insecticides
• Preoperative medication to:
  • Aid relaxation
  • Control heart rate
  • 降低唾液分泌
• Allergic rhinitis(inflammation of the inside of the nose caused by an allergen)
• Chronic obstructive pulmonary disease(a long-term lung condition that makes it hard for you to breathe)
• Overactive bladder(causes a frequent and sudden urge to urinate that may be difficult to control)
• Urinary incontinence
• Parkinson’s disease (a brain disorder that leads to shaking, stiffness, and difficulty in walking, balance, and coordination)
• Frey syndrome (a syndrome that includes sweating while eating [gustatory sweating] and facial flushing)
• Hypermotility of lower urinary tract
• Sialorrhea (drooling or excessive salivation -a common problem in neurologically impaired children)
• Cystitis(inflammation of the bladder)
• Hyperhidrosis(abnormally excessive sweating that is not necessarily related to heat or exercise)
• Asthma

Common side effects include:

• Dry mouth
• Constipation
• Drowsiness
• Dizziness (feeling faint, weak or unsteady)
• Dry skin
• Headache

Other rare side effects include:

• Confusion
• Urine retention
• Hallucinations (involve hearing, seeing, feeling, smelling, or even tasting things that are not real)
• Memory problems
• Blurred vision
• Trouble urinating
• Trouble breathing
• Irregular heartbeat
• Loss of coordination
