Mechanisms compared
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. Lorazepam: Lorazepam binds the benzodiazepine site of the GABA-A receptor and allosterically enhances the action of the inhibitory neurotransmitter GABA.
