HESPERIDIN HYDROGEL FORMULATION USING PECTIN-CHITOSAN POLYMER COMBINATION

Objective: Hesperidin is flavonoid glycosides that proven to have therapeutic activity to any desease, one of them is colon disease; but, its low solubility (< 100 mg/L) makes small absosption inside the body so it needs delivery system that could deliver hesperidin to the therapy target. The objective of this research is to get optimum formula from hydrogel with polimer pectin-chitosan combination that can control in vitro hesperidin release.Method: Optimum hydrogel formula determination using Design Expert 7.0.0 with factorial method design, resulted in formula plans with pectin-chitosan consentration comparison of (P3% : C1%), (P3% : C2%), (P5% : C1%), (P5% : C2%) respectively.Result: Optimum formula with pectin : chitosan concentration comparison (5% : 1%) has entrapment efficiency about 96.658%; k(/hour) swelling index at pH 5.0, 6.8, and 7.4, about 34.917, 15.766, and 8.146 respectively; drug release at pH 5.0, 6.8, and a medium contained 2% mouse’s caecum about 0.461, 20.116, and 52.955% respectively; and the mucoadhesive strength about 0.184 N/cm2.Conclusion: The combination of pectin-chitosan polymer in hydrogel muchoadhesive matrix can control hesperidin in vitro release with the drug release value at the highest concentration of pectin in medium contained 2% mouse’s saecum that could release drug about 56%. Hesperidin hydrogel release mechanism follows Higuchi kinetic.
