Development And Validation

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.

Objective: A rapid, sensitive and specific reverse phase High performance liquid Chromatography (RP-HPLC) method was developed for the estimation of Fimasartan in bulk and pharmaceutical dosage form. Method: The RP-HPLC analysis was performed isocratically on a Primacel C18 column (150 mm × 4.6 mm internal diameter, 5 μm particle size) using mobile phase of composition Acetonitrile and 0.1% orthophosphoric Acid in 80:20, v/v proportions with a flow rate of 0.8 ml/min. Results: The analyte was monitered with UV-detector at 265 nm. In the developed method Fimasartan elutes at a typical retention time of 2.4 min. The proposed method is having linearity in the concentration ranging from 5-30 μg/ml of Fimasartan. Conclusion: : The method was statistically validated and had been applied to analysis of the drug in bulk and pharmaceutical dosage form.
