title: [Use of very high doses of haloperidol in the treatment of acute psychotic episodes. Clinical and pharmacokinetic analysis apropos of 15 cases].
abstract: High-dosage haloperidol treatment was administered during three weeks in a rapid neuroleptization technique to fifteen patients suffering from acute psychotic episodes. Haloperidol plasma levels were determined by radioimmunoassay. The efficacy of such a therapeutic design seemed fairly good, particularly the rapid improvement during the first week. Yet, tolerance appeared to be low, with a high incidence of adverse effects, some of them unexpected. A very good correlation was observed between haloperidol plasma levels and haloperidol oral doses. By contrast, there was no correlation between plasma levels and clinical improvement. In the same way, the occurrence of adverse effects did not seem to be related to haloperidol plasma levels.
