Mechanism and action
Lady Era: Sildenafil citrate inhibits PDE5, allowing cGMP to accumulate in vascular smooth muscle during sexual arousal. 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.
