Description:  
                                        Mechanism of Action: Barnidipine is a dihydropyridine calcium-channel blocker. It is a peripheral and coronary vasodilator, but has little or no effect on cardiac conduction and -ve inotropic activity is rarely seen at therapeutic doses. admin primarily results in vasodilatation, with reduced peripheral resistance, BP, and afterload, increased coronary blood flow, and a reflex increase in heart rate. This results in an increase in myocardial O2 supply and cardiac output.  |
