Abstract

Objective: This study
was aimed to prepare, characterize and evaluate in situ gel formulation for a
sustained ocular delivery of voriconazole.

Material and Method: In situ gels
were prepared with three different hydrophilic co-polymers: Poloxamer 188, 407
and 388. The formulations were characterized in terms of their clarity, pH,
viscosity drug content uniformity and mechanical/rheological properties.
Moreover, in vitro drug release and stabilitystudies were performed.

Result
and Discussion: The results showed that the optimized in situ
gel formulation had desired in vitro properties and a good stability over the
period of 3 months. Texture profile analysis presented that formulations
offered suitable adhesive and mechanical properties. P2-V formulation exhibited
pseudo-plastic flow and typical gel-type mechanical spectra (G′ > G″) at
different frequecy values and at different temperatures. Moreover, all
formulations showed a sustained drug release for 24 hours. In conclusion,
voriconazole loaded in situ gel could be offered as an encouraging strategy as
ocular systems for ocular infections treatment.
