    Abstract: Tadalafil is used for the treatment of the erectile dysfunction (ED) and pulmonary arterial hypertension. It is having low aqueous solubility thus it shows poor bioavailability of about 28% by after oral administration. To improve its solubility and dissolution profile solid dispersions (SDPs) of Tadalafil was prepared by physical mixing and solvent evaporation method using polyvinyl pyrollidone-K30 (PVP-30) as a hydrophilic polymeric carrier in different proportions with respect to drug (drug to polymer ratio 1:1 to 1:5). Drug and polymer compatibility studies were performed using FTIR study. The best suitable ratio and method was selected on the basis of enhanced aqueous solubility of drugs. Further selected SDPs were evaluated for various parameters like DSC analysis, percentage yield, percent drug content, saturation solubility, percent drug dissolution and stability studies. FTIR study indicated no incompatibility between Tadalafil and PVP-K30. SDPs prepared with drug to polymer ratio 1:3 and solvent evaporation method was found to be best as they shown significant increased (up to 10 fold) in aqueous solubility in comparison with that of others. DSC study also suggested the depression in the crystalline nature of Tadalafil. Selected SDPs exhibited good stability up to 3 months at 25 ± 2°C /60 ± 5% RH. Based on the results it can be concluded that, SDPs shown remarkable increase in the aqueous solubility and dissolution of Tadalafil and it may improve oral bioavailability of drug as compared with plain drug.

    AN OVERVIEW ABOUT NOVEL FAST DISSOLVING ORAL FILMS

    Abstract: Nowadays, novel fast dissolving oral films (FDF) have come in existence as an alternative dosage form in comparison with tablet, capsules, syrup and other oral dosage forms with respect to patient convenience and compliance. Fast dissolving oral films are helpful to paediatric and geriatric patients who experience difficulties in swallowing traditional oral solid-dosage forms. The FDF drug delivery systems are solid dosage form which disintegrate or dissolve within seconds when placed in the mouth cavity without need of water or chewing. FDF provide better drug dissolution, faster onset of action, bypassing the first pass metabolism of drugs and thus enhance their oral bioavailability with reduced dosing frequency. These formulations are suitable for cough, cold, sore throat, allergenic conditions, nausea, pain, hypertension and CNS disorders. The present review provides the details about the recent advancement in design and development of oral fast dissolving film.
