Hyoscyamine
Identification
- Name
- Hyoscyamine
- Accession Number
- DB00424
- Description
Hyoscyamine is a tropane alkaloid and the levo-isomer of atropine.2 It is commonly extracted from plants in the Solanaceae or nightshade family.2 Research into the action of hyoscyamine in published literature dates back to 1826.6 Hyoscyamine is used for a wide variety of treatments and therapeutics due to its antimuscarinic properties.7,8
Although hyoscyamine is marketed in the United States, it is not FDA approved.7,8

As a drug that is not FDA approved, hyscyamine has no official indications.7,8 Intravenous hysocyamine has been used to reduce gastric motility, reduce pancreatic pain and secretions, to facilitate imaging of the gastrointestinal tract, treat anticholinesterase toxicity, treat certain cases of partial heart block, improve visualization of the kidneys, and for symptomatic relief of biliary and renal colic.7 Intravenous hyoscyamine is also used pre-operatively to reduce secretions of the mouth and respiratory tract to facilitate intubation.7 Oral hyoscyamine is used to treat functional intestinal disorders, for symptomatic relief of biliary and renal colic, and symptomatic relief of acute rhinitis.8

Hyoscyamine is not FDA approved, and so it has not official indications.7,8 However, it is used as an antimuscarinic agent in a number of treatments and therapies.7,8 Hyoscyamine has a short duration of action as it may need to be given multiple times per day.7,8 Patients should be counselled regarding the risks and signs of anticholinergic toxicity.7,8
- Mechanism of action
Hyoscyamine competitively and non-selectively antagonises muscarinic receptors in the smooth muscle, cardiac muscle, sino-atrial node, atrioventricular node, exocrine nodes, gastrointestinal tract, and respiratory tract.3,7,8 Antagonism of muscarinic M1, M4, and M5 receptors in the central nervous system lead to cognitive impairment; antagonism of M2 in the sinoatrial and atrioventricular nodes leads to bradycardia and lowers contractility; and antagonism of M3 in smooth muscle results in reduced peristalsis, bladder contraction, salivary secretions, gastric secretions, bronchial secretions, sweating, increased bronchodilation, mydriasis, and cycloplegia.3,4,5
