Mechanism and action
Lipitor: Atorvastatin competitively inhibits HMG-CoA reductase, the rate-limiting enzyme in hepatic cholesterol synthesis. Estrace: Estradiol binds to estrogen receptors (ERα and ERβ) in target tissues and modulates gene expression for vascular, bone, reproductive, central nervous system and metabolic functions.
