Abstract
Statin drugs (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) are one of the most widely prescribed drugs today. They are considered first-line therapy to lower blood serum cholesterol levels in conjunction with therapeutic lifestyle changes for both primary and secondary prevention of cardiovascular events. In the following discussion, a brief explanation of the background of statins will explain why they are deemed so important today. The similarities and differences between the different statins will be addressed, including a look at dosage, side effects, and cautions for the seven 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors currently available.
