Fig. 4From: Human targeted phenobarbital presents a poor substrate of gut microbiome deciphering new drug targets beyond pharmacokinetic curbsPhenobarbital absorbance (µg ± SE, N = 6) per mg of microbial mass measured in different groups: A1 = Control (untreated), groups based upon post-phenobarbital oral treatment (15 mg/kg of body weight) at sampling times A2 = 2 h, A3 = 3 h, A4 = 4 h, A5 = 5 h and A6 = 6 h. Alphabets on mean bars show a significant difference between groups (P ≤ 0.05)Back to article page
