In vitro-in vivo evaluation of tetrahydrozoline-loaded ocular in situ gels on rabbits for allergic conjunctivitis management.

Ocular allergy is one of the most common disorders of the eye surface. The conventional eye drops lack of therapeutic efficacy due to low ocular bioavailability and decreased drug residence time on eye surface. Hence, the present research work aimed to formulate, optimize, and evaluate the in situ gel for ophthalmic drug delivery.

Evaluation of burn wound healing activity of novel fusidic acid loaded microemulsion based gel in male Wistar albino rats.

The objective of the present research was to examine the possible usage of microemulsion based gel for fusidic acid (FA) dermal application as burn wound treatment. During the preparation of microemulsion, ethyl oleate as oil phase, tween 80 as a surfactant, ethanol as co-surfactant, water as aqueous phase were used. The prepared microemulsions were evaluated for clarity, pH, viscosity and FA content.
