Development and validation of liquid chromatogrphic method for Trazodone hydrochloride


Abstract
A simple, isocratic, rapid and sensitive high performance liquid chromatographic method has been developed for quantitative determination of Trazodone Hydrochloride and its three process related impurities. The method has been validated for the determination of related substances in Trazodone Hydrochloride using a C18, ODS (4.6mm×250mm×10μ m) column by keeping the flow rate of 1.5ml / min and having sensitivity of 0.2. The elution is carried out using a mobile phase consisting of methanol l80 ml, Acetonitrile 180 ml, Tetrahydrofuran 40 ml, and Trifluroacetic acid (0.5%) 600 ml. The detection isbeen carried out at 252 nm with injection volume of 10 μ L. The run time is 15 minutes for estimation of related substance. The precision, Linearity and accuracy of the method are demonstrated for Trazodone Hydrochloride. Specificity of the method is also been studied.

A Validated specific Stability-indicating RP-HPLC method for Aripiprazole and its related substances

Image
ABSTRACT : A validated specific stability indicating reversed-phase liquid chromatographic method was developed for the quantitative determination of Aripiprazole and its related substances in bulk samples, pharmaceutical dosage forms in presence of degradation products. Forced degradation studies were performed on bulk sample of Aripiprazole as per ICH prescribed stress conditions using acid, base, oxidative, thermal stress and photolytic degradation to show the stability indicating power of the method. Significant degradation was observed during basic stress and no degradation was observed in other stress conditions. The chromatographic method was optimized using the samples generated from forced degradation studies and the impurity spiked with Aripiprazole. Good resolution between the peaks corresponds to impuritiy-1, degradation products from the analyte were achieved on YMC PACK C18 column using the mobile phase consists a mixture of Sodium dihydrogen Orthophosphate dehydra...
