A validated simple, sensitive, specific and precise RP-HPLC method was developed for the determination of Gabapentin in pure and pharmaceutical formulations. Method was carried on Zodiac C18 column (250 mm × 4.6 mm × 5 µ particle size) using Methanol : Acetonitrile : Triethylamine (50 : 25 : 25) as mobile phase. Detection was carried out by U.V. at 211 nm. The proposed method obeyed linearity in the range of 10-60 µg/mL. and met all specifications as per ICH guidelines. Statistical analysis revealed that this method can be used in routine quality control studies of Gabapentin in pure and its formulations.
