Brief Title  ICMJE Bioequivalence Study of Lamotrigine Tablets 25 mg (2 x 25 mg Tablets) Under Fed Condition
Official Title  ICMJE An Open Label, Randomized, Two-Period, Two-Treatment, Two-Sequence, Crossover, Balanced, Single Dose Oral Bioequivalence Study of Lamotrigine Tablets 25 mg (2 × 25 mg Tablets) and 'LAMICTAL®' (Lamotrigine) Tablets 25 mg (2 × 25 mg Tablets) in Healthy Adult Human Subjects Under Fed Conditions.
Brief Summary This is an open Label, randomized, two-period, two-treatment, two-sequence, crossover, balanced, single dose pivotal study. The purpose of this study is to assess the bioequivalence between Test Product and the corresponding Reference Product under fed condition in healthy adult human subjects.
Detailed Description

Objective of this pivotal study was to assess the bioequivalence between Test Product: Lamotrigine Tablets 25 mg (2 x 25 mg)of M/s Ipca Laboratories Limited, India and the corresponding Reference Product: LAMICTAL® (Lamotrigine) Tablets 25 mg (2 x 25 mg) of GlaxoSmithkline, USA, under fed condition in healthy adult human subjects in a randomized crossover study.

The study was conducted with 28 healthy adult subjects. In each study period, a single 2 X 25 mg dose of either test or reference was administered to the subjects as per the randomization schedule in each study period with about 240 mL of water at ambient temperature in sitting position.

The duration of the clinical phase was approximately 26 days including washout period of at least 21 days between administrations of study drug in each study period.
