CADUET Film-coated tablet Ref.[50597] Active ingredients: Amlodipine Atorvastatin Atorvastatin and Amlodipine

CADUET (amlodipine and atorvastatin) tablets combine the calcium channel blocker amlodipine besylate with the HMG CoA-reductase inhibitor atorvastatin calcium.

Amlodipine besylate is chemically described as 3-ethyl-5-methyl(±)2[(2-aminoethoxy)methyl]4(o-chlorophenyl)-1,4-dihydro-6-methyl-3,5-pyridinedicarboxylate, monobenzenesulphonate. Its empirical formula is C₂₀H₂₅C_lN₂O₅∙C₆H₆O₃S.

Atorvastatin calcium is chemically described as [R-(R*, R*)]2(4-fluorophenyl)-ß, δ-dihydroxy-5-(1-methylethyl)- 3-phenyl-4-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic acid, calcium salt (2:1) trihydrate. Its empirical formula is (C₃₃H₃₄ FN₂O₅)2Ca∙3H₂O.

The structural formulae for amlodipine besylate and atorvastatin calcium are shown below.

Amlodipine besylate:

Atorvastatin calcium:

CADUET contains amlodipine besylate, a white to off-white crystalline powder, and atorvastatin calcium, also a white to off-white crystalline powder. Amlodipine besylate has a molecular weight of 567.1 and atorvastatin calcium has a molecular weight of 1209.42. Amlodipine besylate is slightly soluble in water and sparingly soluble in ethanol. Atorvastatin calcium is insoluble in aqueous solutions of pH 4 and below. Atorvastatin calcium is very slightly soluble in distilled water, pH 7.4 phosphate buffer, and acetonitrile; slightly soluble in ethanol; and freely soluble in methanol.

CADUET is available as film-coated tablets containing:
