The purpose of this study was to develop a pH-triggered in situ gelling vehicle for ophthalmic delivery of puerarin. The effect of hydroxypropyl-beta-cyclodextrin (HP-beta-CD) on the aqueous solubility and in vitro corneal permeation of puerarin was also investigated. The puerarin solubility increased linearly and proportionally to the HP-beta-CD concentrations and 5% (w/v) HP-beta-CD enhanced ...

abstractvarious nanoparticles have been investigated as novel drug delivery systems, including solid lipid nanoparticles (slns). due to their rapid clearance from systemic circulation, nanoparticles do not provide sustained action in most cases. different strategies have been employed to overcome this problem. in this direction, the present study introduces erodible in-situ forming gel systems ...

preparation and characterization of thermoresponsive in-situ forming poloxamer hydrogel for controlled release of nile red-loaded solid lipid nanoparticles. nanoparticles (nps) are cleared rapidly from systemic circulation and do not provide sustained action in most cases. to solve this problem, this investigation introduces an erodible in-situ forming gel system as potential vehicles for prolo...

Poor bioavailability is one of the most significant problems in delivery ocular drug system. Ophthalmic ointments, solutions and suspensions are frequently used dosage forms to treat disease, their effectiveness as a compromised by several limitations that lead poor bioavailability. In situ gel promising strategy improve drugs. The purpose this review discuss formulation characterization gel. T...

Introduction: This study is to formulate the Euterpe Oleracea in-situ gel for better treatment of conjunctivitis. The ophthalmic drug solution can treat ocular infections effectively. Aim: Formulation and evaluation Eutepe conjunctivitis Methodology: containing prepared by using different polymers like carbopol-940, HPMC K15, K100, K4M, as a pH triggered gelling system, these are used controlle...
