Hydroxymethylglutaryl-coenzyme A reductase inhibitors are "compounds that inhibit HMG-CoA reductases. They have been shown to directly lower cholesterol synthesis.[1]
Classification
The following classification has been proposed based on molecular structure:[2][3]
Type 1
Type 1 statins (e.g., mevastatin, lovastatin, pravastatin, simvastatin) bind to HMG-CoA reductase using a decalin ring.
Type 2
Type 2 statins (e.g., fluvastatin, cerivastatin, atorvastatin, and rosuvastatin) bind to HMG-CoA reductase using a fluorophenyl group.
Effectiveness
Statin therapy benefits about 1 of every 24 diabetic patients who use the treatment for 5 years if they are similar to the patients in the meta-analysis by Kearney et al (Number needed to treat is 24).[4]
