Objective: The aim of the present study was to enhance the dissolution of a practically insoluble Nifedipine by liquisolid compact technique and to enhance the onset of action by Orodispersible tablet technique. Materials and methods: Orodispersible liquisolid compact of Nifedipine were prepared by direct compression method using PEG 400, Microcrystalline cellulose PH 102 and Aerosil 200 as non-volatile solvent, carrier, coating material respectively and co-processed superdisintegrants (Crosspovidone and croscarmellose sodium) in the ratio of 1:1, 1:2, 1:3. The liquisolid compacts were characterized by X-ray powder diffraction, Scanning electron microscopy and FT-IR studies. The statistical analysis for stability studies was carried out by Student’s t-test (SPSS SOFTWARE VERSION 16.0) at a level of 𝑃 = 0.05. Results and conclusion: Orodispersible liquisolid compacts of Nifedipine tablets (F3) containing co-processed superdisintegrants in the ratio of 1:3 exhibits quick disintegration time and maximum drug release. No significant difference (𝑃 value 0.969 > 0.05) was found in the dissolution rate of the stored formulation when compared with freshly prepared formulation. Conclusion: This research work may be useful to formulate Orodispersible tablets using Liquisolid technique which may give rapid onset of action by rapid absorption, maximize efficacy and hence increase patient compliance.
