Improved corneal bioavailability of ofloxacin: biodegradable microsphere-loaded ion-activated in situ gel delivery system
The aim of the study was to improve corneal penetration and bioavailability of ofloxacin (OFX) eye preparations. OFX was incorporated in poly (lactide-co-glycolide) as biodegradable microspheres using oil in oil emulsion solvent evaporation technique. The prepared OFX microspheres were then incorporated in Gelrite(®) in situ gel preparation. In addition, OFX Gelrite-based in situ gel formulatio...
متن کاملA Review: Polymeric In-situ Gel System
Smart polymeric systems represent promising means of delivering the drugs; these polymers undergo sol-gel transition, once administered. In-situ gel structure occurs due to one or combination of different stimuli like pH change, temperature modulation and ionic exchange. The formation of gels depends on factors like temperature modulation, pH change, presence of ions and ultra violet irradiatio...
متن کاملMicrosponges Enriched Gel (MEGs): A Novel Strategy for Opthalmic Drug Delivery System Containing Ketotifen
Microsponge containing ketotifen drug with three different proportions of ethyl cellulose and drug were obtained successfully using quasi-emulsion solvent diffusion method. These formulations were studied for particle size and physical characterization. These microsponges enriched gel formulation were prepared by using 2 and 3 % w/w of SCMC and studied for viscosity, pH, gel strength, spreadabi...
متن کاملIon-activated In Situ Gelling Ophthalmic Delivery Systems of Azithromycin
Gelation of pectin caused by divalent cations especially calcium ions has been applied to develop an ophthalmic formulation of azithromycin in the present study. Rapid elimination of drug on instillation into cul de sac would be minimal with in situ gelling ophthalmic solution leading to increased precorneal contact time and prolonged drug delivery. In the formulation development studies pectin...
متن کاملIntra Nasal In situ Gelling System of Lamotrigine Using Ion Activated Mucoadhesive Polymer
Background A novel drug delivery system for treating acute epileptic condition. Objective To develop an intranasal mucoadhesive formulation of Lamotrigine (LTG) loaded insitu gel, for the treatment of epilepsy to avoid possible side effects and first pass metabolism associated with conventional treatment. Methods Lamotrigine was loaded into different polymeric solutions of gellan and xantha...
