ABSTRACT
This study is carried out to assess the effects of rosuvastatin and simvastatin on blood vessels for possible vasorelaxant effect. The study is also translating the possible vasorelaxant effect in Wistar rats for a subsequent fall in systolic blood pressure. It is evident from the EC50, that rosuvastatin is more effective on relaxing N.E induced contractions, while simvastatin is more effective on relaxing KCL induced contractions. Simvastatin is equipotent when compared to effects of amlodipine on KCl induced contractions in denuded aortae. Simvastatin produced significant right shift in test concentration 1.1× 10-6M with its respective EC50 -1.85logCa++M as compared to its respective control EC50 -3logCa++M. Rosuvastatin also produced significant right shift in the EC50. In conclusion, it is stated that rosuvastatin and simvastatin relax the aortic strips preparations through inhibition of voltage gated calcium channels and inhibition of N.E induced contractions. Rosuvastatin and simvastatin have additive effects when used in the presence of a standard vaso-relaxant drug like amlodipine, which further confirms its additive effect on decreasing the systolic blood pressure of hypertensive rats (P<0.05).
