Abstract

Objective: The goal of the present investigation was to improve the solubility and bioavailability of atovaquone tablet, using in-house biosynthesized biosurfactant in the ternary system of solid dispersion containing hydrophilic polymers with varying concentrations of biosurfactant. Atovaquone is an anti-malarial agent and belongs to biopharmaceutical classification system class IV.


Methods: The solid dispersion of binary and ternary mixture was prepared using hydroxyl propyl methyl cellulose (HPMC) and biosurfactant respectively by a solvent evaporation method. All the atovaquone tablet formulations were prepared by incorporation of physical mixture, binary and ternary solid dispersed products with excipients by direct compression method. Pre-compression and post-compression parameters of atovaquone tablets were evaluated. In vivo bioavailability study was performed using female albino rabbits.


Results: In vitro dissolution profile of binary and ternary system of solid dispersion products showed 8.65% and 34.64% respectively. Precompression and post-compression values of all atovaquone tablets formulations were within the specified limits. In vitro dissolution efficiency of F2 and F5 were 1.44 fold and 6.62 fold respectively, in accordance to the F1. In vivo study revealed that bioavailability of optimized formulation F5 was increased by 2.5 times and time to reach peak concentration was reduced to 1.4 h, in accordance to pure atovaquone suspension.


Conclusion: Potential application of biosurfactant in the solid dosage form of atovaquone tablet was proved for enhanced dissolution rate and bioavailability of atovaquone for malaria treatment.
