Sustainable spectrophotometric fingerprinting resolution technique for concurrent quantification of ofloxacin and bromfenac in rabbit aqueous humor with ocular pharmacokinetic application

Year: 2026

Type: article

Abstract: . Following a simple protein-precipitation step, the technique was successfully applied to spiked rabbit aqueous humor samples, with recoveries between 97.8% and 102.1%. Matrix effect assessment confirmed negligible interference, with ME% values of -1.12% (OFL) and -0.98% (BMF). The validated technique was then used in an ocular pharmacokinetic study in rabbits following a single topical instillation of a combined OFL-BMF ophthalmic solution. The concentration-time profiles of both drugs in aqueous humor were effectively characterized, and key pharmacokinetic parameters were determined. Sustainability assessment indicated excellent trichromatic scores, confirming their suitability for ocular matrix analysis. This technique offers a sustainable platform for analyzing OFL and BMF in biological fluids, making it highly valuable for ocular bioavailability and pharmacokinetic studies.
