Estimation of Nevirapine Anhydrous Bulk Formulation by Using IR, RP- HPLC, GC Methods

The non nucleoside reverse transcriptase inhibitor Nevirapine (NEV), formulating sample is analyzed with instruments Infrared spectroscopy (IR), Reverse phase High performance liquid chromatography (RP-HPLC) and Gas chromatography (GC), the type of functional groups present in the NEV sample was analyzed with IR, the concentration of Nevirapine compounds NEV A, B and impurity-1 in the formulating nevirapine sample and the assay of nevirapine was done with HPLC with retention time greater than 5 and presence of residual solvents such as Dichloro methane, Chloroform, Dimethyl formamide, O-xylene was estimated with GC, the loss on drying and residue on ignition as 0.14 and 0.04% w/w respectively.
