Dissolution Improvement of Simvastatin by Surface Solid Dispersion Technology

Improvement of Dissolution Behavior of Paracetamol Using Solid Dispersion Technique

Paracetamol is an important anti-inflammatory and analgesic drug widely used in biological disorders. One of major problems with this drugs is its low solubility thus dissolution rate in biological fluid, which results into poor bioavailability after oral administration. In this study polyvinyl pyrrolidone (PVP) is used to enhance bioavailability of paracetamol. Paracetamol and PVP are used in ...

Increase in Dissolution Rate of Simvastatin by Amorphous Solid Dispersion System with Hydroxypropylmethylcellulose Polymer

The objective of the present study was to prepare amorphous solid dispersion system simvastatin–hydroxypropylmethylcellulose (HPMC) to enhance the dissolution rate. Amorphous solid dispersion of simvastatin was prepared by solvent technique using HPMC as carrier with ratio of 1:1, 1:3 and 1:5 (w/w). Physicochemical properties of solid dispersions were investigated by X-ray powder diffraction, t...

Surface Solid Dispersion of Glimepiride for Enhancement of Dissolution Rate

Surface solid dispersions using water-insoluble carriers like crospovidone, croscarmellose sodium, sodium starch glycolate, pre-gelatinized starch, potato starch and Avicel PH 101 were investigated to enhance the dissolution rate of the glimepiride, a poorly water insoluble drug. The effect of various carriers on dissolution profile was studied using presence absence model. The surface solid di...

Combinational approach using solid dispersion and semi-solid matrix technology to enhance in vitro dissolution of telmisartan

The present investigation was focused to formulate semi-solid capsules (SSCs) of hydrophobic drug telmisartan (TLMS) by encapsulating semi-solid matrix of its solid dispersion (SD) in HPMC capsules. The combinational approach was used to reduce the lag time in drug release and improvise its dissolution. SDs of TLMS was prepared using hot fusion method by varying the combinations of Pluronic-F68...
