ABSTRACT
Brinzolamide is an effective carbonic anhydrase inhibitor widely used in glaucoma therapy but limits its application due to inadequate aqueous solubility and permeability. The aim of the present research work is the development and characterization of brinzolamide-loaded ultradeformable bilosomes to enhance the corneal permeation of the drug. These ultradeformable bilosomes were prepared by ethanol injection method and evaluated for physicochemical properties, particle size, morphology, drug release, ultra-deformability, corneal permeation, and irritation potential. The optimized formulation exhibited an average particle size of 205.4 ± 2.04 nm with mono-dispersity (0.109 ± 0.002) and showed entrapment efficiency of 75.02 ± 0.017%, deformability index of 3.91, and release the drug in a sustained manner. The brinzolamide-loaded ultradeformable bilosomes released 76.29 ± 3.77% of the drug in 10 h that is 2.25 times higher than the free drug solution. The bilosomes were found non-irritant to eyes with a potential irritancy score of 0 in Hen's egg-chorioallantoic membrane assay. Brinzolamide-loaded ultradeformable bilosomes showed 83.09 ± 5.1% of permeation in 6 h and trans-corneal permeability of 8.78 ± 0.14 cm/h during the ex vivo permeation study. The acquired findings clearly revealed that the brinzolamide-loaded ultradeformable bilosomes show promising output and are useful in glaucoma therapy.
