Meanings of phenobarbital concentrations in English

Therefore, timing is not important when collecting blood samples to measure serum phenobarbital concentrations in most epileptic dogs treated long-term with phenobarbital.

Conclusions and clinical relevance: There is no therapeutically relevant change in serum phenobarbital concentrations throughout a daily dosing interval in most epileptic dogs.

Significant differences were not detected among mean serum phenobarbital concentrations when comparing the trough, 3-hour, and 6-hour samples for all dogs.
