Description: Pranidipine, also known as OPC-13340 and FRC 8411, is a potent and selective calcium channel blocker potentially for the treatment of angina pectoris and hypertension. Pranidipine enhances nitric oxide-induced vascular relaxation. pranidipine prevents the left ventricular remodeling process accompanied by systolic and diastolic dysfunction, and inhibits abnormal cardiac gene expression after myocardial infarction.
