BACKGROUND: Based on the Biopharmaceutics Classification System (BCS) system, irbesartan is a drug that belongs to the class II BCS group which has limitations in terms of dissolution rates with low bioavailability of 26% -60%. These limitations to bioavailability can be overcome by solid dispersion with hydrophilic matrices such as Poloxamer. Irbesartan is an angiotensin receptor blocker. At present, it is widely used in dealing with hypertension due to endothelial dysfunction.
AIM: This study aims to determine endothelial function blood markers can be examined, such as adhesion molecules (ICAM-1) and IL-8 pro-inflammatory cytokines.
MATERIAL AND METHODS: Research on the effects of irbesartan-poloxamer-188 solid dispersion on ICAM-1 and IL-8 in hypertensive rats has been carried out. The formation of solid dispersion through dissolution method while induction of hypertension using 2.5% NaCl and prednisone 1.5 mg/Kg BB orally in 3 treatment groups, irbesartan dose was 13.5 mg/kg. The parameters observed were serum ICAM-1 and IL-8 levels.
RESULTS: The result showed that the solid dispersion of irbesartan-poloxamer-188 could reduce ICAM-1 and IL-8 levels in hypertensive rats which differed significantly from the positive control group (p < 0.05).
CONCLUSION: This study concluded that the solid dispersion of irbesartan-poloxamer-188 effects and decreases ICAM-1 levels in the serum of hypertensive rats. Solid dispersion of irbesartan-poloxamer-188 can influence and reduce IL-8 in the serum of hypertensive rats.
