Evolution of plasma acetate concentration during ethanol metabolism in man.
Following oral administration of ethanol to ethylic as well as non-ethylic volunteers, the entire time course of plasma acetate concentration has been observed. The curve shows a typical evolution in three phases: (1) a quick ascending phase (2) a steady state characterized by a mean concentration (-C) (3) a first-order decrease, characterized by its half-life (t1/2) These parameters show significant variations (increase of -C, decrease of t1/2) in the ethylic subjects, in comparison with the non-ethylic ones. The variation of the area under the acetate curve according to the dose of ethanol given, is linear. The comparison of such a development with the one, typically non-linear, of the area under ethanol curve previously analyzed for the same subjects, may guess the origin of the non-linearity of ethanol kinetics.
