TL;DR: The suggested methods were successfully applied for the analysis of the two drugs in laboratory prepared mixtures and their pharmaceutical formulation and the obtained results were statistically agreed with those obtained by the reported method.

TL;DR: In this article, two sensitive colorimetric methods for determination of tricyclic antidepressant drugs in their pure forms and pharmaceutical preparations were described. But the methods hold their accuracy and precision well when applied to the determination of the cited drugs dosage forms.

TL;DR: Three spectrophotometric methods including Vierordt's method, derivative, ratio spectra derivative, and thin layer chromatography-UV densitometric method were developed for simultaneous determination of drotaverine HCl and nifuroxazide in presence of its impurity, 4-hydroxybenzohydrazide.

TL;DR: In this paper, a thin-layer chromatographic (TLC) method for analysis of escitalopram oxalate (ESC-OX) (S-enantiomer) in presence of "in-process impurities" using β-cyclodextrin (β-CD) and urea as two different selectors was developed and validated as per ICH guidelines.

TL;DR: In this article, two novel, sensitive, and selective stability-indicating chromatographic methods were described for the analysis of zopiclone (ZOP) in the presence of its degradation products, namely, 7-oxo-6,7-dihydro-5H-pyrrolo[3,4-b]pyrazin-5-yl-4-methylpiperazine-1-carboxylate (hydrolytic DEG) and 5H-polycyclic pyrazine-5,7(6
