Pharmaceutical Development and Evaluation of Reservoirtype Ciprofloxacin Ocular Insert

Abstract

Ocular inserts of ciprofloxacin hydrochloride were prepared with the aim of achieving once a day administration. Drug reservoir was prepared using sodium CMC while rate controlling membrane was prepared using Eudragit RS100 and RL100. Ocular inserts were evaluated for their physicochemical parameters like thickness, weight uniformity, drug content, percent moisture loss, and percent moisture absorption. The in vitro drug release studies were carried out using Bi-chambered donor receiver compartment model.  In vitro drug release kinetic data was treated according to Zero, First, and Higuchi kinetics to access the mechanism of drug release. At the end of 24th hr, in-vitro percentage drug release was obtained for the formulations RF1 was% 46.02 and for RF5 was 98.23%. The drug release from the formulation RF5 (Eudragit RS and RL 100 (1:1)) was 98.23 % at the end of 24th hour which was available as controlled and prolonged. In Kors Meyer Peppas, n value in optimized batch (RF5) was observed 1.399 which indicated super case II transport occurs. All physical parameters evaluated were satisfactory. So formulation RF5 was selected as the best formulation.
