Abstract
The effect of solid dispersions (SDs) on the solubility of the nonsteroidal anti-inflammatory drug ketoprofen was determined. Ketoprofen and its SDs with poly(ethylene glycol) PEG-400, -1000, -1500, -2000, and -3000 were studied. Dissolution of ketoprofen from the SDs increased by 1.2 – 1.8 times; the dissolution rate, by 1.7 – 2.4 times. The improved release of ketoprofen from the SDs was proposed to be due to several factors such as solubilization and amorphization of the compound and formation of intermolecular H-bonds. The results could be used to develop rapidly dissolving ketoprofen solid dosage forms.
