Pirenzepine Uses

 Pirenzepine (CAS NO.28797-61-7) is an antimuscarinic agent that inhibits gastric secretion at lower doses than are required to affect gastrointestinal motility, salivary, central nervous system, cardiovascular, ocular, and urinary function. It promotes the healing of duodenal ulcers and due to its cytoprotective action is beneficial in the prevention of duodenal ulcer recurrence. It also potentiates the effect of other antiulcer agents such as Cimetidine and Ranitidine. It is generally well tolerated by patients. Aslo, it can used in the treatment of peptic ulcers, as it reduces gastric acid secretion and reduces muscle spasm. It has no effects on the brain and spinal cord as it cannot diffuse through the blood-brain barrier. And it has been investigated for use in myopia control.
