Four normal monkeys each equipped with an EEG plug and two indwelling catheters for drug infusion and sampling, respectively, were administered valproic acid (VPA) before and after a 12-hr light, 12-hr dark phase shift. Before day-night reversal, diurnal oscillations of VPA plasma levels under steady-state intravenous constant-rate infusions were 30-50%, with maximum concentrations during the dark phase of the cycle. After reversal, maximum VPA plasma concentrations tended to follow the dark phase shift. The correlation was not perfect, nor was the sleep cycle completely reversed since the animals slept less after the phase shift. Possible mechanisms of the diurnal plasma level fluctuations and the importance of oscillations of this magnitude to clinical drug regimens are discussed.
