Pharmacokinetics
The pharmacokinetics of phenylethanolamine, after i.v. administration to dogs, were studied by Shannon and co-workers, who found that the drug followed the "two-compartment model", with T1/2(α) ≃ 6.8 mins and T1/2(β) ≃ 34.2 mins; the "plasma half-life" of phenylethanolamine was therefore about 30 minutes.
