This article refers to simple isocratic reverse-phase high-performance liquid chromatographic method (RP-HPLC) developed for the simultaneous quantification of Escitalopram Oxalate (EST) and Clonazepam (CZP) in active pharmaceutical ingredient and pharmaceuticals. The separation of the two drugs was attained using a C₁₈ column (250mm×4.6mm, 5µ) as a stationary phase. The mobile phase was used as a mixture of methanol; acetonitrile; and 0.05M potassium dihydrogen orthophosphate buffer (pH 4 adjusted by orthophosphoric acid) with an isocratic ratio of 40:20:40 v/v. Detection was made by using PDA detector at 210 nm. Escitalopram Oxalate (RT= 4.428 minutes) and Clonazepam (RT= 6.532 minutes) were separated in a single chromatographic run with resolution of 8.719. The calibration plot indicated good linear relationship with r2 = 0.998 for Escitalopram Oxalate in concentration range of 32 µg/ml - 48 µg/ml and r2 = 0.999 for Clonazepam in concentration range of 16 µg/ml - 24 µg/ml. The retrievals for Escitalopram Oxalate and Clonazepam were found to be 99.75% and 99.00%, respectively. The established analytical method was validated and found acceptable as per ICH guidelines for linearity, precision, accuracy, specificity, limit of detection, limit of quantification, robustness and stability. Escitalopram Oxalate and Clonazepam individually as well as in combination were exposed to different stress conditions like acid, base, thermal, photolytic and oxidation degradation and peaks of a degraded product were well determined from peaks of pure drug. This method is modest, quick and appropriate for routine quality control analysis. Keywords: Reverse Phase – HPLC; Escitalopram Oxalate; Clonazepam; Validation; Degradation study.

This study was designed to develop and validate a simple and efficient high performance liquid chromatography (HPLC) method to determine flunixin concentrations in Asian elephant’s (Elephas maximus) plasma. Flunixin was administered orally at a dose of 0.8 mg/kg, and blood samples were collected. Flunixin extraction was performed by adding an equal amount of acetonitrile to plasma and centrifuging at 4500 rpm for 25 minutes. The supernatant was removed, and flunixin was analyzed using HPLC-UV detection. Two methods were developed and tested utilizing two different mobile phases either with or without adding methanol (ACN: H2O vs. ACN: H2O: MeOH). Both methods showed excellent linearity and reproducibility. The limit of detection was 0.05 ug/ml and limit of quantification was 0.1 ug/ml. the efficiency of flunixin recovery was maximized by the addition of methanol to mobile phase (ACN: H2O: MeOH as 50:30:20) at 95% in comparison to 23% without methanol. In conclusion, adding methanol to HPLC methods for extraction of flunixin from elephants’ plasma yielded higher recovery rate than without methanol.
