Utilization of poloxamer as well as combinations with other polymers as base in ophthalmic in situ gel dosage form

Abstract

The aim of this review was to find out which formulation were good for making in-situ gels using a combination of poloxamer and other bases. Formulation was characterized for appearance and homogeneity, pH and gelation studies, viscosity measurements, in vitro drug release, drug content, and stability studies. In vivo rabbit, eye irritation tests were conducted to evaluate the irritation of the in-situ gel delivery system; in addition, osmolality testing, sterility test, and isotonicity evaluation were also carried out. The results have shown that in-situ gel solution can increase residence time and also maintain the mechanism of drug release.
