DESCRIPTION
Amlodipine besylate, USP is a long-acting calcium channel blocker.
Amlodipine besylate, USP is chemically described as 3-Ethyl-5-methyl
(±)-2-[(2-
aminoethoxy)methyl]4-(2-chlorophenyl)-1,4-dihydro-6-methyl-3,5-pyridinedicarboxylate,
monobenzenesulphonate. Its molecular formula is C
H CIN O •C H O S, and its structural formula
is:
Amlodipine besylate, USP is a white crystalline powder with a
molecular weight of 567.1. It is slightly
soluble in water and sparingly soluble in ethanol. Amlodipine besylate
tablets are formulated as white
tablets equivalent to 2.5, 5 and 10 mg of amlodipine for oral
administration. In addition to the active
ingredient, amlodipine besylate, USP, each tablet contains the
following inactive ingredients:
microcrystalline cellulose, dibasic calcium phosphate anhydrous,
sodium starch glycolate, and
magnesium stearate.
CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
Amlodipine is a dihydropyridine calcium antagonist (calcium ion
antagonist or slow-channel blocker)
that inhibits the transmembrane influx of calcium ions into vascular
smooth muscle and cardiac muscle.
Experimental data suggest that amlodipine binds to both
dihydropyridine and nondihydropyridine binding
sites. The contractile processes of cardiac muscle and vascular smooth
muscle are dependent upon the
movement of extracellular calcium ions into these cells through
specific ion channels. Amlodipine
inhibits calcium ion influx across cell membranes selectively, with a
greater effect on vascular smooth
muscle cells than on cardiac muscle cells. Negative inotropic effects
can be detected _in vitro_ but such
effects have not been seen in intact animals at therapeutic doses.
Serum calcium concentration is not
affected by amlodipine. Within the physiologic pH range, amlodipine is
an ionized compound
(pKa=8.6), and its kinetic interaction with the calcium channel
receptor is characterized by a gradual ra
