Estimation of sertraline by chromatographic (HPLC‑UV273 nm) technique under hydrolytic stress conditions
Purpose: In this paper, simple, specific and accurate RP-HPLC method was developed in order to study decomposition of sertraline (SRT) under the hydrolytic stress conditions (acid, neutral, alkaline and oxidative). Materials and Methods: The best separation of SRT and its degradation products were achieved on reverse phase LiChoCART with Purospher (RP-18e) column. The mobile phase was composed of methanol/water (75:25, v/v). The detection wavelength was 273 nm. The method was validated and response was found to be linear in the drug concentration range of 10–200 µg ml−1 with correlation coefficient of 0.998. Results: The RSD values for intra- and inter-day precision were < 0.65 and < 0.72%, respectively. Employing RP-HPLC method, degradation products were detected in the exposed samples. Conclusion: It was found that the susceptibility of SRT to hydrolytic decomposition increased in following manner: Neutral condition < alkaline condition < acid condition < oxidative condition.
