A study of the relationship between pharmacokinetic profiles and temporal changes in quantitative EEG following imipramine administrations showed that a single dose of imipramine administered by different routes decreased the alpha-power spectra of healthy subjects. The EEG changes were time-related and their latent period and duration depended not on the plasma levels, but on the pharmacokinetic parameters. These effects were produced by imipramine without the influence of its desmethylated product, desipramine. Also, both single and multiple doses after oral or intramuscular imipramine administrations to depressive patients led to two types of EEG responses, with Type 1 patients exhibiting fast improvement of their symptoms. Therefore, chronologically-recorded quantitative EEG should be useful in judging the clinical prognosis of depressive patients after the imipramine treatment. At a steady state, however, neither the EEG recording nor the evaluation of the plasma level is adequate for the judgment.
