Injections of increasing doses of n-propanol provoke blood concentration curves of exponential decays with dose dependent rate constants. The n-propanol-specific clearance is approximately 10 ml/min. It is determined by a Michaelis-Menten-metabolism (max. velocity of metabolizing: approximately 2.5 mg/l min; Michaelis-Menten-constant: approximately 10 mg/l) and is inhibited in the presence of ethanol.
