Novel Nasal in situ Gelling System for Treatment of Sinusitis

In situ gelling systems based on temperature-dependent phase transition containing pheniramine and phenylephrine were developed using combination of Poloxamers, different cellulose polymers (HPMC) and xanthan gum. The formulations were tested for in vitro gelation, appearance, pH, drug content, in vitro drug release, mucoadhesive strength, preservative effi cacy and stability. In vitro release ...

Temperature Triggered In situ Gelling System for Betaxolol in Glaucoma

Article history: Received on: 07/11/2012 Revised on: 29/12/2012 Accepted on: 22/01/2013 Available online: 28/02/2013 The aim of this research is to develop thermo sensitive drug vehicles for glaucoma therapy in in-situ form to overcome the problems of poor bioavailability, naso lachrymal drainage and rapid precorneal elimination exhibited by conventional eye drops. Thermo sensitive ophthalmic d...

Ion-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...
