This is a single dose, open-label, randomized, two-period crossover study to demonstrate the bioequivalence of lamotrigine dispersible/chewable tablets (5mg×5) and lamotrigine compressed tablets (25mg) in healthy Chinese male subjects in fasting conditions. 24 healthy Chinese male subjects will be enrolled to provide data from at least 22 evaluable subjects . In Period 1, subjects will be randomized in equal numbers to be dosed with either lamotrigine dispersible/chewable 5mg×5 tablets or lamotrigine compressed tablet 25mg×1. Following a washout of at least 14 days, subjects will be crossed over in Period 2 to receive the treatment that they did not receive in Period 1.
