Methods: In situ gel was prepared by a hot method using 0.6% of gelrite, 0.25% hydroxypropylmethylcellulose (HP MC K 4 M) and 0.023% tamarind gum as bioadhesive polymers for sustained drug rele ase. Optimization was done by Box Behnken Design wi th different concentration of gelrite (X 1 ), HPMC K 4 M (X 2 ) and tamarind gum (X 3 ) as independent variables. In situ gel was optimiz ed based on mucoadhesion index (Y1), Gel strength ( Y2) and in vitro drug release (Y3). Influence of the quantitative v ariable on the dependent variable was predicted by a polynomial equation. Results: Infrared spectroscopy excluded any interaction betw een drug and excipients. The selected independent v ariables significantly influenced the responses and were able to sustain the drug rel ease. The prepared gel with a pH of 6.8 to 7.4 exhi bited non-newtonian flow with no ocular irritation. The formulation remained stable with no change in pH and viscosity after 30 d of stability study. Conclusion: Thus, moxifloxacin hydrochloride (MH) in situ gel i s a viable alternative to a conventional delivery s ystem with the properties of sustained drug release, prolonged ocular retention, and improved corneal penetration.
