Mechanism and action
Amoxil: Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) and blocking the cross-linking of peptidoglycan strands. Ovestin: Estriol in Ovestin binds estrogen receptors with shorter receptor occupancy than estradiol, producing a 'weak' estrogenic effect.
