Formulation and Optimization of Self Emulsifying Drug Delivery System For Effective Anthelmintic Therapy

Abstract

The present study aims to develop and optimize a self-emulsifying drug delivery system for paediatric patients to improve the oral bioavailability of the anthelmintic drug, Praziquantel (PZQ) and to perform it’s in-vitro dissolution study. The solubility of PZQ was estimated in various vehicles to select proper component combination. Capmul MCM (oil), Cremophore RH40 (surfactant) and PEG400 (co-surfactant) were employed to construct pseudo-ternary phase diagrams. Eight formulations composed of Capmul MCM, at Smix ratios (1:1, 2:1 & 3:1) were selected. The optimized formulation F7 has a mean globule size 14.73 nm with a negative zeta potential -44.43 mV. The results indicated that PZQ loaded SEDDS, showed enhanced solubilization and nanosizing potential to improve the absorption of the drug.
