Enhancement of dissolution rate of piroxicam by electrospinning technique

Enhancement in Dissolution Rate of Piroxicam by Two Micronization Techniques

Piroxicam is a nonsteroidal anti-inflammatory drug that is practically insoluble in water. The oral absorption rate of piroxicam is dependent on its dissolution rate in the GI tract. The aim of this study was to enhance the dissolution of piroxicam by a microcrystallization technique. The preparation of microcrystals of piroxicam was done by two methods, solvent change and pH shift. In the solv...

piroxicam liquisolid system: a method of dissolution rate enhancement

Enhancement of Dissolution Rate of Efavirenz by Solid Dispersion Technique

Efavirenz is an HIV-1 specific, non-nucleoside reverse transcriptase inhibitor (NNRTI).It is an antiretroviral agent indicated for the treatment of human immunodeficiency virus type 1 (HIV-1) infection, which is not soluble in water and lower absorption in gastric fluid. In order to improve the solubility and oral absorption of the drug in gastric fluid and to enhance its dissolution rate, soli...

Enhancement of Loperamide Dissolution Rate by Liquisolid Compact Technique.

Purpose: The aim of present study was to improve the dissolution rate of poorly soluble drug Loperamide (LPM) by liquisolid compact technique. Methods: Liquisolid compacts of LPM were prepared using Propylene glycol (PG) as a solvent, Avicel pH 102 as carrier, Aerosil as coating material and Sodium Starch Glycolate (SSG) as superdisintegrant. Interactions between the drug and excipients were ex...

Crystal modifications and dissolution rate of piroxicam.

Piroxicam is a nonsteroidal anti-inflammatory drug with low aqueous solubility which exhibits polymorphism. The present study was carried out to develop polymorphs of piroxicam with enhanced solubility and dissolution rate by the crystal modification technique using different solvent mixtures prepared with PEG 4000 and PVP K30. Physicochemical characteristics of the modified crystal forms of pi...
