The main purpose of this study was to develop a novel, in situ gel system for sustained delivery of ranitidine hydrochloride. Ranitidine in situ gels at 0.2%, 0.5%, and 1.0% gellan gum concentration (w/v) were prepared, respectively, and characterized in terms of preparation, viscosity and in vitro release. The viscosity of the gellan gum formulations in solution increased with increasing conce...
The goal of this study was to develop and characterize an ion-activated in situ gel-forming estradiol (E2) solution eye drops intended for the prevention of age-related cataracts. Accordingly, in situ gelling eye drops were made using gellan gum as an ion-activated gel-forming polymer, polysorbate-80 as drug solubilizing agent, mannitol as tonicity agent, and combination of potassium sorbate an...
The oral delivery of drugs with a narrow absorption window in the gastrointestinal tract (GIT) is often limited by poor bioavailability with conventional dosage forms due to incomplete drug release and short residence time at the site of absorption. In-situ gel provides the best way to overcome problems of immediate release and short gastrointestinal residence of liquids. The in situ gel dosage...
in order to achieve prolong corneal contact time of norfloxacin(nfx) for treatment of extra ocular diseases, a ph triggered nanoparticulate in situ gelling system was designed to explore dual advantage of nanoparticles and in situ gelling system, for its ocular delivery. nfx loaded nanocarriers were developed by ionotropic gelation technique using chitosan as a matrix forming polymer, cross-lin...
objective(s): in a new approach, following the development in metal oxide chemistry, the ibuprofen as low water soluble nonsteroidal anti-inflammatory drug diffused into synthetic sol-gel derived nano porous g-alumina by an impregnation method in order to increase the solubility and control the drug release in physiological environment. methods: sol-gel method was utilized for the fabrication o...

PURPOSE To develop an in situ gel system comprising liposome-containing paclitaxel (PTX) dispersed within the thermoreversible gel (Pluronic® F127 gel) for controlled release and improved antitumor drug efficiency. METHODS The dialysis membrane and membrane-less diffusion method were used to investigate the in vitro drug release behavior. Differential scanning calorimetry (DSC) thermal analys...
The objective of this study was to evaluate the pharmacokinetic characteristics of enrofloxacin (ENR) in situ forming gel in pigs following a single intramuscular administration. Twelve healthy pigs were randomly divided into two groups (6 pigs per group), then administered 20 mg/kg body weight (b.w.) ENR in situ forming gel and 5 mg/kg b.w. ENR conventional injection respectively. Highperforma...
