Abstract

Despite the fact that the circadian variations in the density of striatal dopaminergic D2 receptors are well documented, there are few reports concerning whether these variations may regulate the extrapyramidal symptoms produced by antipsychotic drugs. To test this hypothesis, we selected 18 male hospitalized schizophrenic subjects, who had been treated for 2 wk with 10 mg haloperidol three times a day. The extrapyramidal symptoms were evaluated 1 h after each haloperidol administration (e.g. 09:00, 14:00 and 19:00 hours). The diurnal profiles of haloperidol-induced extrapyramidal symptoms showed that akathisia and dystonia were milder in the morning and increased in severity during the night. However, Parkinsonian symptoms were more severe during the morning evaluations than during the evening tests. The difference in the diurnal pattern of the haloperidol-induced side-effects, suggests that receptor-related mechanisms with a different circadian profile contribute to the induction of the extrapyramidal symptoms.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
