Description
Curator's Comment: description was created based on several sources, including

Lemildipine is a 1,4-dihydropyridine calcium channel blocker which is under phase III development by Banyu (Merck and Co), in Japan, for its potential to treat hypertension and cerebrovascular ischemia. In one study, involving five patients with essential hypertension accompanied by cerebrovascular disorder, lemildipine, administered orally at doses of 5 to 20 mg/day, significantly lowered blood pressure and increased cerebral blood flow. Another study in 31 patients with essential hypertension demonstrated that lemildipine has significant pressure lowering effects without affecting serum lipids. Worldwide rights to market the drug have been assigned to Kowa in Japan.

In Vitro Use Guide
In a whole-cell configuration with voltage clamp, the blocking effect of NB-818 (LEMILDIPINE) on L-type Ca2+ current (ICa) in guinea-pig ventricular cells appeared much more slowly than that of nifedipine and was hardly washed out. The potency of NB-818 to block ICa was markedly enhanced under depolarized conditions compared to that under polarized conditions. Such a voltage-dependent blocking action on ICa was less pronounced for nifedipine. These results indicate that NB-818 is a slow-acting Ca2+ channel antagonist with much high vascular selectivity. Its vascular selectivity may be at least in part related to the marked voltage-dependent inhibition of ICa.
