Application

Cilnidipine has been used:
  • in cell viability assay of pheochromocytoma (nPC12) cells
  • in photoirradiation and photodegradation studies
  • to understand effect on albuminuria in diabetic nephropathy

Biochem/physiol Actions

A slow-acting Ca2+ channel blocker, antihypertensive; vasodilator.
Cilnidipine is a slow-acting Ca2+ channel blocker; antihypertensive; vasodilator; dual blocker of L-type voltage-gated Ca2+ channels in vascular smooth muscle and N-type Ca2+ channels in sympathetic nerve terminals that supply blood vessels. Cilnidipine may offer an advantage over nifedipine as the long term intake of the latter has been linked to increased risk of myocardial infarction and mortality in patients with coronary artery disease. Cilnidipine lowers blood pressure, but has less effect on sympathetic activity. Unlike nifedipine, cilnidipine does not inhibit PKC.

Recently, it has been demonstrated that L-/N-type calcium channel blockers (CCBs), cilnidipine, but not L-type CCB, decreased urinary protein in renin-angiotensin system (RAS), inhibitor-treated hypertensive patients with macroproteinuria. However, the antiproteinuric effect of cilnidipine was weaker in diabetic patients than
