Frequent occurrence, higher morbidity andmortality rate of atherosclerosis associated hypertension inelderly people shambles health care system worldwide. Sothe present study was deliberated to formulate and appraiserational combination, containing immediate release portionof atorvastatin calcium (ATR) and sustained release (SR)portion of felodipine (FEL) in bilayered multicomponenttablet formulation for elderly people. A 32 factorial designwas used to prepare atorvastatin calcium and felodipinetablets separately. For each drug total nine batches (A1?A9 for ATR; F1?F9 for FEL) were prepared. The amount ofsodium starch glycollate (X1) and lactose (X2) were used asindependent variables for atorvastatin calcium andhydroxypropyl methyl cellulose 50 cps (X1) and talc (X2) forfelodipine tablets. Talc being hydrophobic diluents has beentried as release retardant. On the basis of flowability, compressibility,compactibility, tensile strength and drug release,the both layers of formulation were optimized, and subsequently,bilayered multicomponent tablet formulation wasprepared and evaluated. The optimized tablet formulationsof atorvastatin calcium (Batch A3) released 76 % of drugafter 30 min, while (Batch F8) of felodipine showed drugrelease up to 79 % after 10 h and followed peppas releasepattern (r² = 0.9862). The similar release pattern wasnoticed in the bilayered tablet formulation of atorvastatincalcium and felodipine meeting the USP requirements. Hence, it can be concluded that, the aforesaid bilayeredformulation can meet the needs of those elderly people, whosuffer from mild hypertension and hyperlipidemia.
