Formulation optimization and evaluation of fast dissolving film of aprepitant by using design of experiment

The concept of fast dissolving dosage form has become popular as new delivery system. This system will provide maximum therapeutic efficacy, increased bioavailability and maximum stability by reducing the frequency of dosage. It will also avoid first pass metabolism of the drugs. This system provides more rapid drug absorption from the pre gastric area which may provide quick onset of action. The present research aimed to prepare fast dissolving films (FDF) of aprepitant used in the prevention and treatment of chemotherapy-induced nausea and vomiting. The FDF was prepared using solvent casting method and optimized employing central composite design considering two independent variables film forming polymer (pullulan) and PEG 400. Disintegration time, wetting time, drug release and folding endurance were taken as dependent variables. The prepared optimized formulation showed minimum disintegration time (20 s), highest dissolution rate (88.87%) and satisfactory physicochemical properties. It is evident from the above results that the developed formulation can be an innovative dosage form to improve the drug delivery, onset of action as well as improve patient compliance.
