Pharmacokinetics of althesin--comparison with lignocaine.

The plasma concentrations of alphaxalone were measured with a gas chromatographic technique in six patients following a single i.v. injection of Althesin, and in five volunteers following oral administration. A two-compartment open model was used in the pharmacokinetic analysis of the data, and the plasma clearance of alphaxalone was similar to the blood flow through the liver. A comparison with the pharmacokinetics of lignocaine was made.
