Efonidipine (Cat.No:I000445) is a calcium channel blocker used in the treatment of hypertension (high blood pressure). It blocks calcium channels in smooth muscles, leading to relaxation and dilation of blood vessels, resulting in reduced blood pressure. Efonidipine may also have additional cardioprotective effects.
