S Amlodipine Besylate

Levamlodipine (INN), also known as levoamlodipine or S-amlodipine is a pharmacologically active enantiomer of amlodipine. Amlodipine belongs to the dihydropyridine group of calcium channel blocker used as an antihypertensive and antianginal agent. Amlodipine blocks the transmembrane influx of calcium into the vascular and cardiac smooth muscles resulting in vasodilation and hence a fall in blood pressure. Levamlodipine is an allosteric modulator and acts on the L-type of calcium channels. Elderly hypertensives with diabetes mellitus exhibits higher response to levamlodipine therapy than non-diabetic patients. Levamlodipine is an effective switch-over option for the elderly patients who experience oedema and other adverse events with racemic amlodipine.
