Healthy Adults

The study will be conducted on healthy Japanese adult males (20-45 years old).
The study will measure and compare blood levels of carbamazepine in three phases: carbamazepine tablets taken with water, carbamazepine tablets taken with Thickened water, and carbamazepine fine granules taken with Thickened water. There will be a 14-day withdrawal period as a washout period for carbamazepine, and the effects of taking the drug with Thickened water will be evaluated in an open-label study. All studies will be conducted on the same study subjects.
