Tacrolimus solid dispersion was prepared using glycerylbehenate(Compritol~?ATO888) and Pluronic F127 as the carrier materials with hot-melt method, which was then blended with hydrogel matrix materials, such as HPMC and lactose, the powders were directly compressed into tablets. In vitro drug release tests were carried out to evaluate the performance of the solid dispersions and the tablets. The dissolution rate of tacrolimus was significantly improved by the lipid-based solid dispersion, and the incorporation of HPC into the solid dispersion obviously improved its stability after storage. Extended release tablets loaded with tacrolimus solid dispersion showed prolonged drug release patterns over 24 h, the release patterns of the tablets can be tailored by the compositions of the matrix materials, including the types and content of HPMCs. A modified processing method that directly mixed the melted solid dispersion with HPMC powders improved the uniformity of the solid dispersion inside the tablet matrix and release profile. The release data of the extended release tablet fitted well to the Korsmeyer–Peppas model with n value of 0.85, which suggested diffusion-and erosion-controlled release mechanism. The combination of lipid-based solid dispersion and HPMC hydrogel matrix may find wide applications in the extended release dosage forms of high potent, water-insoluble drugs.展开更多

Different FGA-1, FGA-2, FGA-3 (Formulated Gliclazide Aerosil;weight ratio, 1:1) and FPG-1, FPG-2 (Formulated Plain Gliclazide) tablet batches were formulated, prepared, evaluated and characterized. All the findings of pre-compression factors were found to be satisfactory and post-com- pression parameters revealed good mechanical integrity and good uniformity in all formulations. All the formulated tablets satisfied the compendia limits of weight variation, friability and the disintegration time. Among all formulations, FGA-3 was optimized based on in vitro drug release findings, disintegration time, hardness and other quality attributes. The percent of drug release from the formulated FGA tablets containing gliclazide loaded aerosil is about 3 fold higher when compared with the tablets formulated and prepared with plain gliclazide (FPG) and the tested commercial brands in first 60 minutes. There was no significant change noted in the drug content and drug release pattern in the FGA tablets batches when stored in 40℃?and 75% RH for three months. It was thus concluded that SDs formulations of gliclazide could be successfully used to design and develop a solid dosage form of the drug, which would have significant benefits over the existing commercial brands.展开更多
