Abstract:
In this study the effect of liquisolid technique on the dissolution profile of spironolactone was evaluated. Different formulations of spironolactone liquisolid compacts were prepared using various amounts of non-volatile vehicles (Poly ethylene glycol ۴۰۰ and glycerin). The ratio of microcrystalline cellulose (as carrier) to silica (as coating powder material) was ۲۰ for all formulations. After preparing tablets by direct compression with constant compression load, the release profiles were evaluated by USP paddle method. Differential scanning calorimeter (DSC) and FTIR were used to evaluate any interaction between spironolactone and other ingredients. The liquisolid tablets exhibited significantly higher dissolution rates in comparison with conventionally direct compressed tablets. Furthermore results showed dissolution rate enhancement of liquisolid tablets by increase in the amounts of non-volatile vehicles. Differential scanning calorimetry showed that, the drug has got solubilized in the liquid vehicle. FT-IR spectroscopy studies of pure spironolactone, liquisolid compacts, glycerin and PEG۴۰۰ supported solubilization of the drug in the liquid vehicle too. The FT-IR spectra also showed that no interactions have been occurred between spironolactone and other ingredients. In conclusion the liquisolid technique can be a suitable method in order to prepare rapid release tablets of poorly water-soluble drugs such as spironolactone.
