abstract：:The pharmacokinetics of TRH and its metabolite deamido-TRH (TRH-OH) were evaluated and compared. After a 60- to 90-min infusion of the appropriate peptide into rats, the MCR, half-life of disappearance (t 1/2), and volume of distribution were calculated. The MCR of TRH averaged 4 ml/min, whereas that of TRH-OH was 6.5...
