Whiteness, redness, blueness and greenness profile assessment and design of experiments approach to microwave-aided sensitive and green spectrofluorophotometric determination of baclofen

Abstract

As a gamma amino butyric acid-ergic agonist, Baclofen is often prescribed to adults and children for the treatment of severe spasticity that originates in the brain or spinal cord. Even after reviewing the literature extensively, no one has documented a method for estimating baclofen using microwave-assisted stability-indicating spectrofluorimetric techniques, despite the abundance of options for baclofen stability, assay, and bioanalysis. Organic solvents, which are typically necessary for current procedures but may be costly and toxic, have a severe effect on aquatic life and the environment. Using green solvents and 4-chloro-7-nitrobezofuran as a fluorescent probe, this work conducted a stability-indicating spectrofluorimetric estimate of baclofen. Through the use of a design-of-experiments technique, a reliable microwave-aided spectrofluorimetric method was developed, with little solvent consumption and time for sample analysis. Prior to conducting response surface analysis and optimizing important variables and responses, a fractional factorial design was used to screen method variables and responses. A central composite design was then employed for these purposes. This flexible spectrofluorimetric technique was used to assess baclofen concentrations in forced degraded samples and marketed formulations. For baclofen determination, the suggested spectrofluorimetric approach was found to be green, quick, easy to use, economical, and user-friendly.
