TL;DR: For the first time, a new variable selection method based on swarm intelligence namely firefly algorithm is coupled with three different multivariate calibration models namely, concentration residual augmented classical least squares, artificial neural network and support vector regression in UV spectral data.

TL;DR: Three different spectrophotometric methods were applied for the quantitative analysis of flucloxacillin and amoxicillin in their binary mixture, namely, ratio subtraction, absorbance subtraction and amplitude modulation and they obtained accuracy, precision and repeatability within the acceptable limits.

TL;DR: The first three UV spectrophotometric methods have been developed of simultaneous determination of two new FDA approved drugs namely; elbasvir and grazoprevir in their combined pharmaceutical dosage form and there was no significant difference between the proposed methods and the manufacturing one with respect to the validation parameters.

TL;DR: Ledipasvir (LED) and Sofosbuvir (SOF) are newly approved antiviral agents co-formulated for treatment of hepatitis C virus as mentioned in this paper, and an accurate and precise TLC densitometric method has been used.

TL;DR: Four rapid, simple, accurate and precise spectrophotometric methods were used for the determination of ciprofloxacin in the presence of metronidazole as interference and were validated according to the ICH guidelines where accuracy, precision and repeatability were found to be within the acceptable limits.
