Abstract
Aim: The present study revolved around determining the effect of increase in the solubility of these drugs at the absorption site using ritonavir as a drug model. Materials & methods: Ritonavir per-oral tablets were prepared using versatile and nonionic surfactants having high solubilization rate, which were further marked with high rate of dissolution. The high rate of dissolution formula applied to the solid state characterization by means of transition electron microscopy, differential scanning calorimetry, scanning electron microscopy, X-ray diffraction and infrared spectroscopy. Results & conclusion: The drug bioavailability was seen to increase expressively by administration of liquisolid tablets as compared with conventional tablets.
