Summary A randomized, two-way, crossover, bioequivalence study was conducted in 20 fasting, healthy, male volunteers to compare two brands of Gabapentin 400 mg capsules, NEOGAB® (manufactured by Hilton Pharma (Pvt) Limited, Progressive Plaza, Beaumont Road, Karachi, Pakistan) as a test and NEURONTIN® (manufactured by Godecke AG/ Germany under license of Parke-Davis) as a reference product. One capsule of either formulation was administered with low-carbonate water after 10 h of overnight fasting. After dosing, serial blood samples were collected during a period of 48 hours. Plasma samples were analysed for Gabapentin by a validated HPLC method. The pharmacokinetic parameters AUC0-24, AUC0-α, Cmax, Tmax, Kel, T1/2, and CL were determined from plasma concentration-time profiles for both formulations and were compared statistically to evaluate bioequivalence between the two brands of Gabapentin, using the statistical modules re-commended by FDA. The analysis of variance (ANOVA) did not show any significant difference between the two formulations and 90% confidence intervals (CI) fell within the acceptable range for bioequivalence. Based on these statistical inferences it was concluded that the two brands exhibited comparable pharmacokinetics profiles.
