Innovative Nanosuspension Formulation for Prochlorperazine and In-vitro Evaluation

Prochlorperazine is a dopamine antagonist and is used to control nausea and vomiting. It is a BCS class II drug which has low aqueous solubility and high permeability. The present study is aimed to formulate and evaluate prochlorperazine nanosuspension to improve solubility and enhance dissolution of Prochlorperazine with varying concentrations of stabilizers such as Tween 80, PVP K30, Poloxamer 188 by using nanoprecipitation method. The developed formulations were characterized for particle size and polydispersity index, total drug content, SEM, Zeta Potential and FTIR. The invitro drug release studies and invitro drug release kinetics were performed for all formulations. FTIR studies revealed that drug is compatible with the excipients. The particle size and poly dispersity index of optimized formulation was found to be 162nm and the zeta potential was found to be -30.2 mV and concluded that the system had sufficient stability. The invitro drug release was found within their acceptable ranges. The rate of dissolution of best batch was enhanced to 93.24 in 120min. Stability studies proved that nanosuspensions were more stable with no significant changes in particle size distribution. Thus the formulated nanosuspension of prochlorperazine offers a superior conventional dosage forms for drug release Keywords: Prochlorperazine, Nanosuspension, Solubility, Dissolution
