Levamlodipine
Levamlodipine, also known as S-amlodipine, is a pharmacologically active enantiomer of [amlodipine], an antihypertensive medication. Levamlodipine belongs to the dihydropyridine group of calcium channel blockers. This medication was first marketed in Russia and India before being granted FDA approval. The names S-amlodipine and levamlodipine may be used interchangeably as both substances are the same, however. As a racemic mixture, amlodipine contains (R) and (S)-amlodipine isomers, but only (S)-amlodipine as the active moiety possesses therapeutic activity.  Levamlodipine was granted FDA approval on 19 December 2019.
