Development and validation of stability indicating spectrophotometric and HPTLC methods for determination of acemetacin

Abstract

Three simple and sensitive methods were developed for the determination of acemetacin (ACM) in presence of its degradation product, indomethacin (DEG). Several methods were evaluated and are presented. Method A was based on measuring the peak amplitude of the first derivative of the ratio spectra 1 DD at 244 nm. In method B, mean centering of ratio spectra method (MCR) was applied, which depends on measuring the mean centered values of ratio spectra of ACM at 234 nm. Method C provided separation of ACM from its DEG on preactivated silica gel 60F254 HPTLC plates using hexane:ethyl acetate:glacial acetic acid (6:4:0.3, v:v:v) as developing system followed by scanning at 254 nm. The suggested methods were validated in compliance with the International Conference on Harmonisation (ICH) guidelines and were successfully applied for quantification of ACM in its commercial capsule. The proposed methods were also statistically compared to a reported HPLC method with no significant difference in performance; indicating the ability of the proposed method to be reliable and suitable for routine analysis of drug product.

Development and validation of a simple and rapid UPLC method for the in-vitro estimation of (-)-epigallocatechin-3-gallate in lipid-based formulations

“…The system suitability test (SST) is an essential part of the analytical method that is used to verify effectiveness of the final operating system [24]. The test was performed by injecting the standard sample in triplicate and the SST parameters were calculated as reported by USP [25], which include capacity factor (k'), selectivity factor (α), resolution factor (Rs), column efficiency (number of theoretical plates, N) [26].…”

Simultaneous determination of carbinoxamine maleate and pseudoephedrine HCl in their pure form and in their pharmaceutical formulation by HPTLC-densitometric method

“…Thin layer chromatography has become a well-established technique for the assay of drugs either in binary or in multicomponent mixtures [20][21][22][23][24][25][26][27]. The proposed method is based on the difference in the retardation factor (RF) between the CRM, PSH and MP.…”

Development and validation of three spectrophotometric methods for determination of pyridostigmine bromide in the presence of its alkaline-induced degradation product

“…The developed MCR method depends on the mean centering of the ratio spectra, it gets rid of the derivative steps and therefore signal-to-noise ratio is increased [29]. This method is able to resolve binary and ternary mixtures in complex samples with unknown matrices [30].…”
