Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)

Primary Outcome Measures:
  • The maximum concentration (Cmax)of first-line TB drugs [ Time Frame: Before and 1, 2, 4, 6 and 10 hours after dosing ]

Secondary Outcome Measures:
  • N-acetyltransferase 1 and 2 (NAT 1 and 2), which effects the metabolism of anti-TB drugs, would be examined. [ Time Frame: Before taking the anti-TB drugs on the fifth day ]

Estimated Enrollment: 16
Study Start Date: July 2009
Estimated Study Completion Date: December 2011
Estimated Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Treatment A
Study agents (Rifater+EMB) will be given approximately 45 minutes "prior to the breakfast."
Drug: Rifater and EMB

The main difference between Treatment A and Treatment B is the time of taking drugs, so the intervention of this study belongs to a behavioral intervention.

The patients assigned randomly the Arm "Treatment A" on the fifth day will be switched to the Arm "Treatment B" on the sixth day. On the other hand, the patients assigned randomly the Arm "Treatment B" on the fifth day will be switched to the Arm "Treatment A" on the sixth day. The flow of intervention is drawn as below.

Treatment A (5th day) ---> Treatment B (6th day) ; Treatment B (5th day) ---> Treatment A (6th day)

Experimental: Treatment B
Study agents (Rifater+EMB) will be given approximately 45 minutes "after the breakfast is finished."
Drug: Rifater and EMB

The main difference between Treatment A and Treatment B is the time of taking drugs, so the intervention of this study belongs to a behavioral intervention.

The patients assigned randomly the Arm "Treatment A" on the fifth day will be switched to the Arm "Treatment B" on the sixth day. On the other hand, the patients assigned randomly the Arm "Treatment B" on the fifth day will be switched to the Arm "Treatment A" on the sixth day. The flow of intervention is drawn as below.

Treatment A (5th day) ---> Treatment B (6th day) ; Treatment B (5th day) ---> Treatment A (6th day)


Detailed Description:

This is a single-center, open-label, randomized, two way crossover design, pharmacokinetics study.

  1. Treatment A: study agents (Rifater+EMB) will be given approximately 45 minutes prior to breakfast.
  2. Treatment B: study agents (Rifater+EMB) will be given approximately 45 minutes after the breakfast is finished.
