A stability-indicating reversed-phase high-performance liquid chromatography method has been developed and validated for the estimation of nevirapine and its impurity, namely the related compound A and the related compound B in combination drug product. The separation was carried out on SUPELCOSIL ABZ (150 mm × 4.6 mm, 5 µm) column. Tablet was admitted to the stress conditions of acid, base, peroxide, thermal, humidity, and photolytic degradation. The degradation products were well resolved from nevirapine, and its impurities peaks and the peak homogeneity of compound were obtained using photo diode array detector, hence proving the stability-indicating nature of the method. Moreover, to prove the selectivity of the method, individual lamivudine, zidovudine, and their main impurities were injected. The developed method was linear for nevirapine from 120 to 360 µg mL^-1, and the linear regression obtained was >0.999. Recovery data were in the range 98.2–101.5%. The limit of quantification for related compound A and related compound B was found to be 0.02%. The proposed method was validated according to the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use guidelines and proved suitable for stability testing and quality control of these drugs in pharmaceutical preparations.
