Burst drug release is often considered a negative phenomenon resulting in unexpected toxicity or tissue irritation. Optimal release of a highly soluble active pharmaceutical ingredient (API) from hypromellose (HPMC) matrices is technologically impossible; therefore, a combination of polymers is required for burst effect reduction. Promising variant could be seen in combination of HPMC and insoluble Eudragits® as water dispersions. These can be applied only on API/insoluble filler mixture as...

Abstract Adsorption of lipid-based formulations, which are usually liquid, onto silicas has been extensively investigated in the past decade to convert them into solid dosage forms. There are conflicting reports on the ability of commercially available porous silicas, like Neusilin® US2, to release lipid formulations completely, especially after long-term storage. In this study, the release of a model drug, probucol, from different formulations of medium chain lipids and a surfactant,...

Abstract The aim of present work was to investigate the role of liquisolid technique in improving dissolution of high dose Progesterone. Progesterone-PEG 400 dispersions were prepared and evaluated for technological properties, and further formulated into liquisolid tablets using Neusilin US2 and Syloid 244 FP as a carrier and coat respectively. Due to polymorphic behavior of Progesterone, liquisolid tablets were investigated by XRPD, DSC and SEM, whereas, improvement in dissolution was studied...
