A review on ophthalmic in - Situ gel

A 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...

Optimization and evaluation of a thermoresponsive ophthalmic in situ gel containing curcumin-loaded albumin nanoparticles

This study aimed to optimize and evaluate a thermoresponsive ophthalmic in situ gel containing curcumin-loaded albumin nanoparticles (Cur-BSA-NPs-Gel). Albumin nanoparticles were prepared via a desolvation method, and the gels were prepared via a cold method. The central composite design and response surface method was used to evaluate the effects of varying Pluronic F127 and Pluronic F68 conce...

A Review On: Alginate Forming In-Situ Gel for Treating Peptic Ulcers and Reflux Disorders

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...

Calsequestrin gel conformation in situ

Calsequestrin (CASQ) is the major component of the sarcoplasmic reticulum (SR) lumen in skeletal and cardiac muscles. This calcium binding protein localizes to the junctional SR (jSR) cisternae where it is responsible for the storage of large amounts of Ca 2+ while it is usually absent, at least in its polymerized form, in the free SR. The retention of CASQ inside the jSR is partly due to its a...
