Formulation and characterization of oral dispersible tablet of aprepitant

The oral route of drug administration is more common and convenient where tablets and capsules emerged as popular dosage form but many patients have dysphasia or difficulty in swallowing which is currently affecting 35% general population. Aprepitant is anti-emetic drug and used in the treatment of chemotherapy in cancer. Fast onset of action is required in this indication there for it was thought to prepare Oral Dispersible Tablet of Aprepitant which would help to avoid first pass metabolism and improve bioavailability also Aprepitant is insoluble in water so, to increase the solubility solid dispersion method (kneading method) was used. Here, Aprepitant ODT is prepared by direct compression method using Polyplasdone XL10 as superdisitegrant and optimized by 32 Full factorial design. Here, Polyplasdone XL10 (x1) and Mannitol(x2) is use as independent variable. while dependent variable are disintegration time and wetting time. Optimized formulation F8 batch showed drug content (98.41±0.91); disintegration time is (18.02±1.20) Wetting time (22.53±0.43). The formulation is stable at 40ºc/75% RH for 30 days.
