Abstract

Cilnidipine is a unique Ca(2+) channel blocker with an inhibitory action on the sympathetic N-type Ca(2+) channels, which is used for patients with hypertension in Japan. Cilnidipine has been clarified to exert antisympathetic actions in various examinations from cell to human levels, in contrast to classical Ca(2+) channel blockers. Furthermore, renoprotective and neuroprotective effects as well as cardioprotective action of cilnidipine have been demonstrated in clinical practice or animal examinations. After the introduction of nifedipine as an antihypertensive drug, many Ca(2+) channel blockers with long-lasting action for blood pressure have been developed to minimize sympathetic reflex during antihypertensive therapy, which have been divided into three groups; namely, first, second, and third generation based on their pharmacokinetic profiles. Since cilnidipine directly inhibits the sympathetic neurotransmitter release by N-type Ca(2+) channel-blocking property, the drug can be expected as fourth generation, providing an effective strategy for the treatment of cardiovascular diseases.
