Self-nanoemulsifying System Optimization for Higher Terconazole Solubilization and Non-Irritant Ocular Administration.

Eye drops' formulations of poorly water-soluble drugs, offer the advantage of crossing the lipophilic cornea, but their limited aqueous solubility may lead to low ocular bioavailability limiting their therapeutic uses. Terconazole (TZ) is an antifungal drug with low aqueous solubility, restricting its application in ocular fungal infection. Thus, the aim of the work in this study is to enhance TZ solubilization, permitting better ocular permeation and higher bioavailability.

Integrated nanovesicular/self-nanoemulsifying system (INV/SNES) for enhanced dual ocular drug delivery: statistical optimization, in vitro and in vivo evaluation.

Ocular drug administration is usually problematic and suffers low bioavailability due to several physiological and biological factors that hinder their effective treatment. Terconazole (TZ) is considered as one of the effective ocular antifungal agents that is usually administrated intravitreally for higher efficacy. The aim of the work in this study is to formulate a TZ-loaded ocular drug delivery system with high efficiency and good tolerability.
