Statins (HMG-CoA reductase inhibitors) are the most prescribed drug class worldwide for cholesterol lowering. In the WikiBiome framework, statins are notable for their microbiome-modulating effects and drug repurposing potential beyond cardiovascular disease—including anti-vaginolysin activity against Gardnerella vaginalis, neuroprotection in Parkinson's, and cancer chemoprevention.

Microbiome Effects

Simvastatin promotes Lactobacillus expansion and cholesterol metabolism in CRC context.

03
Drug Repurposing

BV/vaginolysin: Statins deplete membrane cholesterol → reduce vaginolysin (cholesterol-dependent cytolysin) binding → attenuate Gardnerella virulence.
