NCIt definition : A belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated
from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic
activity. Hyoscyamine functions as a non-selective, competitive antagonist of muscarinic
receptors, thereby inhibiting the parasympathetic activities of acetylcholine on the
salivary, bronchial, and sweat glands, as well as the eye, heart, bladder, and gastrointestinal
tract. These inhibitory effects cause a decrease in saliva, bronchial mucus, gastric
juices, and sweat. Furthermore, its inhibitory action on smooth muscle prevents bladder
contraction and decreases gastrointestinal motility.;
