Present study aims to prepare and evaluate mucoadhesive microspheres by ionotropic gelation method. Among all the formulations M10 was selected as optimized formulation for mucoadhesive microspheres based on the evaluation parameters and drug release studies. In vitro release study of formulation M10 showed 97.11% 12 h in a controlled manner, which is essential for disease like peptic ulcer. The release order kinetics for M10 was best fit with the highest correlation coefficient was observed in Higuchi model, indicating diffusion controlled principle. The innovator Abygate conventional tablet shows the drug release of 97.23% within 1 h. FT-IR and DSC analyses confirmed the absence of drug-polymer interaction. The results obtained from evaluation and performance study of Gatifloxacin mucoadhesive microspheres that system may be useful to achieve a controlled drug release profile suitable for peroral administration and may help to reduce the dose of drug, dosing frequency and improve patient compliance when compared with marketed product.

Gemifloxacin mesylate loaded microspheres were prepared by Ionotropic gelation technique with different drug to carrier ratio. All the microspheres were characterized for particle size, scanning electron microscopy, FTIR study, DSC, percentage yield, drug entrapment, stability studies and for in vitro release kinetics and found to be within the limits. Among all the formulations S8, was selected as optimized formulation based on the physic chemical and release studies. In the in vitro release study of formulation S8 showed 95.92%, after 12 h in a controlled manner, which is essential for anti ulcer therapy. The innovator Gemiflox conventional tablet shows the drug release of 95.23% within 1 h. The drug release of optimized formulation S8 followed zero order and Higuchi kinetics indicating diffusion controlled drug release.
