Perubahan Profil Farmakokinetika Ibuprofen yang Diberikan dengan Kombinasi Vitamin C pada Tikus Putih (Rattus Norvegicus L.)

Abstract

Ibuprofen is one of the NSAID (NonSteroid Anti Inflamation Drug) drugs that has been widely used as antipyretic agent, analgesic dan anti-inflamation. Vitamin C is an important nutrient for the body and has been widely used to maintain health. Earlier study indicate patterns of interaction between vitamin C and NSAID drugs. The aims of this research were to study the influence of vitamin C to the pharmacokinetics profile of ibuprofen. The study was conducted using 9 rats rats, divided into 3 groups (n=3 per group). Each group was treated the following treatment : control ibuprofen (ibuprofen 7.2 mg/200 gBW), dose 1 group (ibuprofen 7,2 mg/200 gBW, and vitamin C 4,5 mg/200 gBW), and dose 2 group (ibuprofen 7,2 mg/200 gBW and vitamin C 9 mg/200 gBW). Blood sampling is done from the vein of rat’s tail at minutes 15, 30, 45, 60, 75, 90, 120, 180, 240, 300 and 360. The quantitation of ibuprofen in plasma was determined by UV spectrophotometer at maximum wavelength. Result showed that vitamin C changed the absorption of ibuprofen by prolonged the maximum plasma concentration time, reduce maximum levels of ibuprofen and vitamin C also changed the elimination of ibuprofen by prolonged the elimination time.
