Bioequivalence Study of Gabapentin 400 mg Capsules Under Fasting Conditions

Not Applicable

Completed

• Conditions: Healthy
• Interventions: Drug: Gabapentin 400mg capsules

• Registration Number: NCT00778271
• Lead Sponsor: Ranbaxy Laboratories Limited

Brief Summary

The objective of this study was to compare the single-dose relative bioavailability of Ranbaxy and Parke-Davis (Neurontin®) 400 mg Gabapentin, following administration of a 400 mg dose under fasting conditions

Detailed Description

This was an open-label, randomized, single-dose, 2-way crossover relative bioavailability study performed on 24 healthy adult volunteers and 2 alternates. A total of 26 subjects (22 males and 4 females) completed the clinical phase of the study. In each period, subjects were housed from at least 10 hours before dosing until after the 36-hour blood draw. Both periods were separated by a wash out period of 7 days A total of 26 healthy adult volunteers (22 males and 4 non-pregnant females) enrolled in and completed the clinical phase of the study enrolled in and completed the clinical phase of the study
