a stability indicating hplc method for determination of mebeverine in the presence of its degradation products and kinetic study of its degradation in oxidative condition

A stability indicating HPLC method for determination of mebeverine in the presence of its degradation products and kinetic study of its degradation in oxidative condition

An HPLC method for determination of mebeverine hydrochloride (MH) in the presence of its degradation products was developed. The degradation of MH was studied under hydrolysis, oxidative and photolysis stress conditions. Under alkaline, acidic and oxidative conditions, degradation of MH was observed. The separation was performed using a Symmetry C18 column and a mixture of 50 mM KH2PO4, acetoni...

validated stability indicating hplc method for the determination of mebeverine in the presence of its degradation products: kinetics study of its degradation in oxidative condition

Validated stability-indicating HPLC method for the determination of mesna in presence of its degradation products.

A rapid and simple stability-indicating liquid chromatographic method was developed and validated for analysis of mesna in the presence of its degradation products in drug substance and drug products in a run time not >5 min. The separation was achieved on a RP amide C16 column at room temperature using methanol-phosphate buffer (10:90, v/v, pH 3.0) as mobile phase at a flow rate of 1 mL min(-1...

Validating a Stability Indicating HPLC Method for Kinetic Study of Cetirizine Degradation in Acidic and Oxidative Conditions

A stability indicating High-Performance Liquid Chromatography (HPLC) method wasvalidated and used to study the degradation of cetirizine dihydrochloride in acidic and oxidativeconditions. The separation was carried out on a Symmetry C18 column and a mixture of 50 mMKH2PO4 and acetonitrile (60:40 v/v, pH = 3.5) was used as the mobile phase. The method waslinear over the range of 1-20 μg/mL of ce...

Stability-indicating methods for the determination of erdosteine in the presence of its acid degradation products.

Four accurate, sensitive, and reproducible stability-indicating methods for the determination of erdosteine in the presence of its acid degradation products are presented. The first method involves processing the spectra by using a first-derivative method at 229 nm in a concentration range of 10-70 microg/mL. The mean percentage recovery was 100.43 +/- 0.977. The second method is based on ratio...
