In the present study, simultaneous quantification of stavudine (SV), lamivudine (LV) and nevirapine (NV) in tablets by UV spectroscopy, reverse phase HPLC (RP-HPLC) and HPTLC methods were developed. In the UV multi-component spectral method, SV, LV and NV was quantified at 266, 271 and 315nm, respectively. In the RP-HPLC method, the drugs were resolved using a mobile phase of 20mM sodium phosphate...
A sensitive, selective, precise and stability-indicating high-performance thin-layer chromatographic method of analysis of nevirapine both as a bulk drug and in formulations was developed and validated. The solvent system consisted of toluene-carbon tetrachloride-methanol-acetone-ammonia (3.5:3.5:2.0:1.0:0.05, v/v/v/v/v). Densitometric analysis of nevirapine was carried out in the absorbance mode...
