Abstract

Objective: The aim of this study was to improve the aqueous solubility of a poorly water soluble drug griseofulvin.

Methods: To accomplish this goal a technique of solid dispersion with polyvinyl pyrolidone (k30) and poloxamer 407 was used. Solubility of griseofulvin alone and the solid dispersion were performed in 10 ml purified water and measured spectrophotometricaly atλ max 295 nm to detect the coefficient of improvement.

Results: Solubility of griseofulvin alone was found to be 0.812 mg and the solubility of solid dispersion ranged from1.64 to 9.56 mg. After generating polynomial models correlating the variables using a D-Optimal mixture design, an optimal formulation with desired response was proposed by the statistical package. For validation, a new solid dispersion formulation based on the optimized composition was prepared and tested for solubility of griseofulvin. The optimized solid dispersion formulation enhances the solubility of griseofulvin by about 12 folds. Increase the amount of poloxamer in the optimized formulation increases the griseofulvin solubility to about 6 folds more than the optimized form.

Conclusion: solid dispersion technique in conjunction with statistical design was shown to be very efficient for the optimization and improvement of aqueous solubility of poorly soluble drugs.
