Mechanisms compared
Demadex: Torsemide blocks the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle, producing potent natriuresis and diuresis. Lamotrigine: Lamotrigine is a phenyltriazine that selectively blocks voltage-gated sodium channels, stabilising neuronal membranes and reducing the release of excitatory neurotransmitters, particularly glutamate.
