isoniazid and Premature Birth

isoniazid has been researched along with Premature Birth in 2 studies

Hydra: A genus of freshwater polyps in the family Hydridae, order Hydroida, class HYDROZOA. They are of special interest because of their complex organization and because their adult organization corresponds roughly to the gastrula of higher animals.
hydrazide : Compounds derived from oxoacids RkE(=O)l(OH)m (l =/= 0) by replacing -OH by -NRNR2 (R groups are commonly H). (IUPAC).

Premature Birth: CHILDBIRTH before 37 weeks of PREGNANCY (259 days from the first day of the mother's last menstrual period, or 245 days after FERTILIZATION).

Pharmacokinetic (PK) Parameter: Adjusted Mean of Area Under the Curve (AUC24h), for EFV

Pharmacokinetic parameter was estimated from population PK modeling fitted to the intensive PK data. AUC0-24h was predicted using population pharmacokinetic model using the NONMEM software program. A 2-compartment model with first-order absorption with transit compartment and first-order elimination with well-stirred liver model to capture hepatic clearance and first-pass extraction with 1 parameter (hepatic intrinsic clearance) was used, (NCT01494038)
Timeframe: Measured at antepartum (third trimester and >= 2 weeks after starting study drug) and week 16 postpartum (+/-) 4 weeks) while on active INH; blood samples were drawn pre-dose and at 1, 2, 4, 6, 8, and 12 hours post-dosing.
