“…[14]. Voltammetry, a very sensitive technique, has proved to be extremely suitable for the analysis of pharmaceuticals, biological fluids, and even environmental samples [15]. Despite this, no voltammetric methods have been described for the determination of cyclobenzaprine, and this is the main aim we report herein.…”

“…The published methods for DLX involve spectrophotometry [6][7][8][9][10][11], spectrofluorimetric approaches based on native fluorescence property [12,13] or derivatization by NBD-Cl to give fluorescent product measured at 523 nm [14]. Thin-layer chromatography was also reported for the detection of DLX [15,16], as were electrochemical methods [17,18], gas chromatography [19] and high-performance liquid chromatography (HPLC) [20][21][22][23].…”

Duloxetine is an antidepressant that exhibits its action by preventing the reuptake of serotonin and norepinephrine by neurons. In this analytical study, we developed two facile, sensitive methods for duloxetine analysis. Both methods rely on the formation of binary association complex between erythrosine-B and duloxetine in an acidic medium using spectrofluorimetric and resonance Rayleigh scattering (RRS) techniques. Spectrofluorimetric method simply uses the quenching property of the formed complex on the native fluorescence of erythrosine-B at an emission wavelength of 557.2 nm ( λ ex = 528.6), while RRS is based on detecting the enhancement in the RRS signal at 357.2 nm. The proposed methods have been validated according to the International Conference on Harmonization guidelines. The approaches provide linear assay of duloxetine hydrochloride over 0.1–2.4 µg ml −1 and 0.2–2.0 µg ml −1 for spectrofluorimetric and RRS methods, respectively. Variables affecting methods and complex formation were studied and optimized. The limit of detection values were 0.03 and 0.056 µg ml −1 for spectrofluorimetric and RRS methods, respectively. Both approaches were applied with acceptable results for formulation analysis and evaluation of cymbatex capsule content uniformity.
