Formulation and Evaluation of Nano Suspension Based Oro Disoersible Film of Aripiprazole

The present study was aimed to enhance the solubility and dissolution of BCS class 4 drug aripiprazole, by nano formulation approach. Acid-base neutralization method had been used to produced nanosuspension. The nanosuspensions remained stable without any aggregations with particle size 209.6nm and PDI 0.247. Zeta potential was found to be 3.5mV. Drug content, Entrapment and solubility of nanosuspension formulations were determined. In vitro drug release of the selected formulation has shown a drug release of 95.63% by the end of 1 hr, whereas plain drug suspension has shown only 12.3% release. XRD and DSC studies revealed that the solid form of aripiprazole altered from the crystalline state to the amorphous state after incorporation into nanosuspensions. Hence, from the results, it can be concluded that Aripiprazole, when formulated by acid-base neutralization method as a nanosuspension, leads to enhanced solubility, dissolution, and stability
