Bioanalytical validated Spectrofluorimetric Method for the Determination of Prucalopride succinate in Human Urine Samples and Its Greenness Evaluation

An economical & eco-friendly spectrofluorometric technique has been developed for the determination of prucalopride succinate (PRU) in human urine on the basis of drug’s native fluorescence. The type of solvent and the wavelengths of excitation and emission have been carefully selected for optimal experimental conditions. In deionized water, the fluorescence intensity was measured at λ emission 362 nm upon excitation at 310 nm. This bio-validated method was carried out using 30uL urine without carrying out any preliminary steps. The calibration curve for PRU shows a linear relationship in a concentration range of 0.75–5.5µg/mL. The validation of this proposed technique obeys EMA Guidelines for validating bioanalytical methods and the greenness assessment was evaluated according to the Analytical GAPI approach.
