Crestor: Rosuvastatin competitively inhibits HMG-CoA reductase, the rate-limiting enzyme in hepatic cholesterol synthesis.
When Aygestin is preferred

When Crestor is preferred
Crestor is approved in adults for the treatment of primary hypercholesterolaemia and mixed dyslipidaemia, for the prevention of cardiovascular events in patients at elevated risk and for the secondary prevention of cardiovascular events.
