title: Absorption of intragastrically administered DDAVP in conscious dogs.
abstract: Plasma concentrations of DDAVP were measured after intragastric administration and intravenous infusion in dogs. Oral ingestion of DDAVP led to a dose dependent increase in peak plasma concentrations as well as area under the curve (AUC). Intravenous infusion of DDAVP (0.13 pmol/l min) resulted in a mean steady-state level of 20.3 pmol/l. Elimination half-lives for oral DDAVP were 77.6 and 76.1 min for low and high doses respectively. T1/2 estimated from the ascending part of the i.v. infusion curve was 50 min. A metabolic clearance rate (MCR) of 3.9 ml/kg . min was assessed from the i.v. steady-state level.
