Formulation and In-Vitro Evaluation of Tadalafil Fast Disintegrating Tablets With Poloxamer

In the present work Tadalafil fast disintegrating tablets were prepared with poloxamer as carrier to enhance the solubility of Tadalafil and in order to disperse at faster rate in the mouth. Chemically Tadalafil is (6R,12aR)-6-(1,3-Benzodioxol-yl) 2,3,6,7,12,12a hexahydro-2-methylpyrazino[10,20:1,6] pyrido [3,4-b]indole-1,4-dione used in erectile dysfunction. In this current work Tadalafil fast disintegrating tablets were formulated from F1-F12 by direct compression method by taking 1:1, 1:2 and 1:3 ratio of poloxamer as a water soluble polymer and super disintegrating agents such as crospovidine, croscarmellose sodium, sodium starch glycolate and kryon. There after FT-IR studies were performed and it was observed that there were no incompatible reactions found between the Tadalafil and excipients used in formulations. Then all the formulations of Tadalafil fast disintegrating tablets F1-F12 were evaluated for pre and post compressional parameters including in-vitro dissolution studies. In which formulation F-12, containing (1:3) ratio of drug-poloxamer and kryon as super disintegrating agent was shown significant changes in wetting time (13±2.09sec), dispersion time (36±3.605sec) and fastest percentage drug release of 99.27±2.78 within 30 minutes was observed.
