Background: Apixaban is an anticoagulant agent that inhibits coagulation factor Xa, commercially available as coated tablets at the dosages of 2.5 and 5 mg. There is no official monograph of the formulation in the current international pharmacopoeias. Objective: This paper presents a simple, specific and precise high-performance liquid chromatographic method for determination of Apixaban in solid dosage form. Method: The mobile phase consists of Acetonitrile – Buffer (320 + 680, v/v). A column containing octadecylsilane chemically bonded to porous silica particles (Chromosil® 100 ODS 150 x 4.6 mm, 5 µm) was used as stationary phase. Detection was performed using a variable wavelength ultraviolet-visible detector set at 230 nm for Apixaban. Solutions were injected into the chromatograph under isocratic condition at a constant flow rate of 1.0 mL/min. Results: The method demonstrates acceptable accuracy and precision and a wide linearity range. Linearity was observed in the range 25-150 µg /mL for Apixaban (r2 =0.999) for drug estimated by the proposed method was in good agreement with the label claim. The accuracy of the methods was assessed by recovery studies at three different levels. Specificity experiments indicated the absence of interference from commonly encountered pharmaceutical additives. The method was found to be precise as indicated by the repeatability analysis, showing %RSD of less than 2. Conclusion: The HPLC method for Assay and dissolution for Apixaban was developed and validated as per guideline and it is found to be precise, specific, accurate and robust.
All statistical data proves validity of the methods and can be used for routine analysis of quality control and stability studies in pharmaceutical dosage form.
