Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)
Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast) was reported for rifampicin and isoniazid.
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
Maximum Observed Plasma Concentration (Cmax)
Cmax was reported for rifampicin and isoniazid.
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 Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - ∞)]
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 - ∞).
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)
Plasma decay half life (t1/2) was reported for rifampicin and isoniazid.
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
Time to Reach Maximum Observed Plasma Concentration (Tmax)
Tmax was reported for rifampicin and isoniazid.
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
