Hyoscyamine Sulfate

ACTIONS:

Hyoscyamine has actions similar to those of atropine, but is more potent in both its central and peripheral effects. This product inhibits gastrointestinal propulsive motility and decreases gastric acid secretions. This product controls excessive pharyngeal, tracheal, and bronchial secretion. Once absorbed, this product disappears rapidly from the blood and is distributed throughout the entire body. The majority of hyoscyamine sulfate is excreted in the urine unchanged within the first 12 hours and only traces of hyoscyamine sulfate are found in the breast milk.

INDICATIONS AND USAGE:

This product may be used in functional intestinal disorders to reduce symptoms such as those seen in mild dysenteries and diverticulitis. It can also be used to control gastric secretion, visceral spasm and hypermotility in cystitis, pylorospasm and associated abdominal cramps. Along with appropriate analgesics, this product is indicated in symptomatic relief of biliary and renal colic and as a drying agent in the relief of symptoms...
