Online published on 18 October, 2016. Abstract The aim for the present study was to develop a delivery system wherein the retention of ofloxacin could be achieved for increasing local action in gastric region against Helicobacter pylori. Therefore the present investigation is concerned with the development of rice bran oil entrapped zinc pectinate beads containing ofloxacin, which after oral administration were designed to prolong the gastric residence time, thus to increase the bioavailability of the drug. A suitable method of analysis of drug by UV spectrophotometry was developed. Ofloxacin showed maximum absorption at a wavelength 294.5 nm in pH 1.2 hydrochloric acid buffer. The value of regression coefficient (r2) was found to be 0.999, which showed linear relationship between concentration and absorbance. Preformulation study for drug and polymer compatibility by DSC and FTIR gave confirmation about the purity of the drug and showed no interaction between drug and the polymers. Top Keywords Ofloxacin, buffer, DSC, FTIR, bioavailability, microbeads. Top |
