Action
                                             
                                            
Description:  
                                        Mechanism of Action: The vasorelaxant effect of benidipine is due to its affinity towards dihydropyridine binding sites in calcium channels. Binding of benidipine with calcium channels inhibits calcium current. The onset of action is slow, which results in minimal tachycardia or palpitation.  |
