Mechanism and action
Lamictal: Lamotrigine selectively blocks voltage-gated sodium channels, stabilising neuronal membranes and reducing the release of excitatory neurotransmitters, particularly glutamate. Provera: Medroxyprogesterone acetate binds progesterone receptors and produces strong progestational effects: thickening cervical mucus, inhibiting ovulation, thinning the endometrium and reducing endometrial proliferation in HRT…
