Formulation and Development OF BCS Class II Drug
The aim of this research was to develop and evaluate liquisolid compacts of Voriconazole a BCS class II drug. The series of formulations containing Voriconazole drug were formulated by using aerosil a colloidal silicone dioxide and avicel PH microcrystalline cellulose in different ratios by using suitable solvent. Solubility studies were performed in propylene glycol and polyethylene glycol (PEG-200, 400, 600) for the choice of the best non volatile liquid to dissolve Voriconazole. On the basis of the solubility data PEG 600 was chosen as a good solvent for the Voriconazole. Voriconazole was dissolved in solvent PEG 600 for the preparation of solution of drug. Formulated compacts were evaluated for all post compression parameters and the in-vitro drug release study was carried out. All the formulations have shown a very good drug release in 15 min except compressibility problems due to higher loading factor of liquid vehicle for the formulations. The selected formulation FV10 containing 30% of drug solution has shown good drug release of 100.2.% in 15 min compared to dissolution of pure drug and marketed tablet which shown 58.5.5% and 70..6 % respectively.No interactions were found between drug and polymers in FITR as well as DSC. XRD of selected formulation shows that drug present in the formulation is in amorphous form.
