Description Hyoscyamine is a chemical compound, a tropane alkaloid it is the levo-isomer to atropine. It is a secondary metabolite of some plants, particularly henbane (Hyoscamus niger.) Hyoscyamine is used to provide symptomatic relief to various gastrointestinal disorders including spasms, peptic ulcers, irritable bowel syndrome, pancreatitis, colic and cystitis. It has also been used to relieve some heart problems, control some of the symptoms of Parkinson's disease, as well as for control of respiratory secretions in end of life care.

Indication For treatment of bladder spasms, peptic ulcer disease, diverticulitis, colic, irritable bowel syndrome, cystitis, and pancreatitis. Also used to treat certain heart conditions, to control the symptoms of Parkinson's disease and rhinitis.
Pharmacology L-Hyoscyamine, the active optical isomer of atropine (dl-hyoscyamine), is a tertiary amine anticholinergic gastrointestinal agent.
Mechanism of Action Hyoscyamine competes favorably with acetylcholine for binding at muscarinic receptors in the salivary, bronchial, and sweat glands as well as in the eye, heart, and gastrointestinal tract. The actions of hyoscyamine result in a reduction in salivary, bronchial, gastric and sweat gland secretions, mydriasis, cycloplegia, change in heart rate, contraction of the bladder detrusor muscle and of the gastrointestinal smooth muscle, and decreased gastrointestinal motility.
Absorption Absorbed totally and completely by sublingual administration as well as oral administration.
Toxicity Symptoms of overdose include headache, nausea, vomiting, blurred vision, dilated pupils, hot dry skin, dizziness, dryness of the mouth, difficulty in swallowing, and CNS stimulation. LD50=mg/kg(orally in rat)
Protein Binding 50%
Biotransformation Hepatic
