Statins: A Comprehensive Monograph on Pharmacological Mechanisms, Clinical Efficacy, and Therapeutic Controversies

Section 1: Introduction to HMG-CoA Reductase Inhibitors (Statins)

1.1. Historical Context and Pharmacological Origins

The development of statins represents a landmark achievement in modern pharmacology and preventive medicine. Their story begins not in a synthetic chemistry lab, but in the realm of natural product discovery. In the 1970s, researchers seeking microbial inhibitors of cholesterol synthesis identified a potent compound from the fungus Penicillium citrinum, which they named mevastatin (or compactin).[1] Shortly thereafter, a similar and clinically viable compound, lovastatin, was isolated from the fermentation broth of

Aspergillus terreus.[1] These initial discoveries proved the therapeutic principle that inhibiting the enzyme HMG-CoA reductase could effectively lower cholesterol levels in humans. Lovastatin (Mevacor) became the first statin to receive approval from the U.S. Food and Drug Administration (FDA) in 1987, ushering in a new era of lipid management.[3]
