In vitro inhibitory effect of lercanidipine on cholesterol accumulation and matrix metalloproteinases secretion by macrophages.

Plaque rupture and thromboembolism play a major role in atherosclerotic acute syndrome. Experimental studies have demonstrated the potential direct anti-atherosclerotic effects of calcium antagonists. We investigated the in vitro effect of lercanidipine (REC 15/2375), a third-generation, highly lipophilic calcium antagonist on cholesterol metabolism and matrix metalloproteinases secretion in macrophages, two functions that predispose plaques to rupture.
