Primary outcomes

  1. Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)

    Time frame: 0 hour (pre-dose), 0.25, 0.5, 0.75, 1, 1.33 (1 hour 20 minutes), 1.67 (1 hour 40 minutes), 2, 2.33 (2 hours 20 minutes), 2.67 (2 hours 40 minutes), 3, 3.5, 4, 6, 8, 12, 16, 24 hours post-dose on Day 1

    Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast) was reported for rifampicin and isoniazid.

  2. Maximum Observed Plasma Concentration (Cmax)

    Time frame: 0 hour (pre-dose), 0.25, 0.5, 0.75, 1, 1.33 (1 hour 20 minutes), 1.67 (1 hour 40 minutes), 2, 2.33 (2 hours 20 minutes), 2.67 (2 hours 40 minutes), 3, 3.5, 4, 6, 8, 12, 16, 24 hours post-dose on Day 1

    Cmax was reported for rifampicin and isoniazid.

Secondary outcomes

  1. Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - ∞)]

    Time frame: 0 hour (pre-dose), 0.25, 0.5, 0.75, 1, 1.33 (1 hour 20 minutes), 1.67 (1 hour 40 minutes), 2, 2.33 (2 hours 20 minutes), 2.67 (2 hours 40 minutes), 3, 3.5, 4, 6, 8, 12, 16, 24 hours post-dose on Day 1

    AUC (0 - ∞)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - ∞) was reported for rifampicin and isoniazid. It is obtained from AUC (0 - t) plus AUC (t - ∞).

  2. Plasma Decay Half-Life (t1/2)

    Time frame: 0 hour (pre-dose), 0.25, 0.5, 0.75, 1, 1.33 (1 hour 20 minutes), 1.67 (1 hour 40 minutes), 2, 2.33 (2 hours 20 minutes), 2.67 (2 hours 40 minutes), 3, 3.5, 4, 6, 8, 12, 16, 24 hours post-dose on Day 1

    Plasma decay half life (t1/2) was reported for rifampicin and isoniazid.

  3. Time to Reach Maximum Observed Plasma Concentration (Tmax)

    Time frame: 0 hour (pre-dose), 0.25, 0.5, 0.75, 1, 1.33 (1 hour 20 minutes), 1.67 (1 hour 40 minutes), 2, 2.33 (2 hours 20 minutes), 2.67 (2 hours 40 minutes), 3, 3.5, 4, 6, 8, 12, 16, 24 hours post-dose on Day 1

    Tmax was reported for rifampicin and isoniazid.

Other outcomes

  1. Number of Participants With Clinically Significant Changes in Vital Signs

    Time frame: Screening up to Day 2 of intervention period 2

    Criteria for clinical significant change in vital signs: systolic blood pressure (BP) less than (<) 90 millimeters of mercury (mmHg), diastolic BP <50 mmHg, supine and sitting heart rate <40 beats per minute (bpm) or greater than (>) 120 bpm, standing and erect heart rate <40 bpm or >140 bpm. Maximum change from baseline in systolic BP >=30 mmHg, maximum change from baseline in diastolic BP >=20 mmHg. Participants who met the criteria were reported.

  2. Number of Participants With Laboratory Test Abnormalities

    Time frame: Screening up to Day 2 of intervention period 2

    Criteria for laboratory tests abnormalities included: hemoglobin, hematocrit and red blood cells (less than [<] 0.8*lower limit of normal[LLN]); leucocytes (<0.6/ greater than [>] 1.5*limit of reference range [LRR]); platelets (<0.5/>1.75*LRR); neutrophils, lymphocytes (<0.8/>1.2*LRR); eosinophils, basophils, monocytes (>1.2*upper LN [ULN]); bilirubin (>1.5*ULN); aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (>3*ULN); creatinine, urea (>1.3*ULN); fasting glucose (<0.6 />1.5*LRR); uric acid (>1.2*ULN); sodium (<0.95/>1.05*LRR); potassium, calcium, chloride, bicarbonate (<0.9/>1.1*LRR); albumin, total protein (<0.8/>1.2*LRR); creatine kinase (>2.0*ULN); urine red blood cells (RBCs), urine white blood cells (WBCs) (>=20 high-powered field). Total number of participants with any laboratory abnormalities was reported.
