DRUG CLASS AND MECHANISM:
- Hyoscyamine is an anticholinergic drug used for treating irritable bowel syndrome, peptic ulcer disease, hypermotility of the lower urinary tract, and gastrointestinal disorders. Anticholinergics work by blocking the action of acetylcholine in the brain and at nerves throughout the body. Acetylcholine is a neurotransmitter. Neurotransmitters are chemicals made and released by nerves that travel to nearby nerves or, in the case of acetylcholine, nearby muscles and glands where they attach to receptors on the surface of the nerve, muscle or glandular cells. The attachment of the neurotransmitter can stimulate or inhibit the activity of the receptor-containing cells. Anticholinergic drugs like hyoscyamine affect the function of many organs by preventing acetylcholine from binding to its receptors. Hyoscyamine decreases the activity of muscles in the intestine and lower urinary tract. It reduces the production of sweat, saliva, digestive juices, urine, and tears. It also reduces the production of bronchial secretions.
