RP-HPLC METHOD DEVELOPMENT AND VALIDATION OF MACITENTAN WITH ITS KNOWN AND UNKNOWN DEGRADATION IMPURITIES IN ITS TABLET DOSAGE FORM
Keywords:RP-HPLC, Macitentan, Forced Degradation
Objective: To develop and validate macitentan with its known and unknown degradation impurities in its tablet dosage form.
Methods: The RP-HPLC method for macitentan and its impurities was developed and three potential degradation impurities MCA-02, MCA-01 and degradation impurity and N-propyl derivative and N-N dimethyl derivative process impurities were separated. Chromatographic separation was achieved within 70 min on Inertsil C8 (250*4.6 mm, 5 Âµm) column, Using mobile phase A [Ammonium acetate (ph 4.5 adjusted with glacial acetic acid)] and mobile phase B acetonitrile in gradient elution. Other hplc parameter which was optimized flow rate 1.5 ml/min, detection wavelength 266 nm, column oven temperature 30 Â° C and injection volume 20Î¼l. macitentan was subjected to forced degradation also known as stress testing. It was validated as per ICH guidelines.
Results: The drug showed extensive degradation in acidic and basic conditions, a slight degradation in oxidative condition. The developed method was statistically validated for linearity (0.45-2.25 ppm). The result of precision (%RSD<5), robustness, LOD(0.15 ppm) and LOQ(0.45 ppm) are well within limits.% Recovery at LOQ, 50%, 100% and 150% was found to be within limit 80-120 %.
Conclusion: RP-HPLC method was successfully developed with satisfactory separation of macitentan and its impurities. The proposed method was found to be specific, accurate, precise and robust can be used for estimation of macitentan and its impurities and can be successfully employed in the routine analysis of macitentan.
