Abstract:


Introduction: Macitentan is an endothelin receptor antagonist drug used in the treatment of pulmonary arterial hypertension.

Materials and Methods: A new, sensitive, simple, accurate and rapid ultra-performance liquid chromatography in combination with tandem triple quadruple mass spectrometry (UPLC-MS/MS) method has been developed and validated for the determination of macitentan in pharmaceutical formulations. Macitentan and bosentan which are used as internal standard (IS) were detected using atmospheric pressure chemical ionization (APCI) in positive ion, multiple reaction monitoring (MRM) mode by monitoring mass transitions (precursor to product) m/z 589.1→203.3 and 552.6→311.5, respectively. Chromatographic separation was carried out on reverse phase C18 column (5 µm, 4.6 * 150 mm). Water containing 0.2 % acetic acid in acetonitrile (10:90, v/v) was used as the mobile phase in the isocratic elution. The system was optimized with injection volume of 10 µL, column temperature of 35 °C and flow rate of 1 mL min-1 Retention times were 1.97 min for macitentan and 1.72 min for IS.

Results and Discussion: The calibration curve with a high correlation coefficient (0.9997) was linear range 0.5-500 ng mL-1. The lower limit of quantitation (LLOQ) and average recovery values were determined as 0.5 ng mL-1 and 99.7 %, respectively. The developed novel method has been successfully applied for the determination of macitentan in pure form and pharmaceutical formulations.

Conclusion: The present method is the first study developed and validated for the determination of macitentan from the pharmaceutical preparations and pure form by UPLC-MS/MS method in the literature.
