Nicotinic acetylcholine receptor antagonist effect of fluoxetine in rat hippocampal slices

Hennings, Esteban C.P., Kiss, Janos P., Vizi, E.Sylvester·1997·Brain Research

Abstract

We compared the effect of mecamylamine and fluoxetine on the hippocampal noradrenaline (NA) release evoked by nicotine in vitro. Nicotine (100 microM) increased the basal release of [3H]NA from rat hippocampal slices. This effect was blocked by the potent nicotinic antagonist mecamylamine in a dose-dependent manner (IC50 = 0.19 microM). The selective serotonin reuptake inhibitor (SSRI) fluoxetine also antagonised the response to nicotine in a dose-dependent manner with a similar strength (IC50 = 0.57 microM). Our data indicate that fluoxetine has nicotinic acetylcholine receptor antagonist effect in the central nervous system. The possible clinical significance of this finding is discussed.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Antidepressant drugs behave as noncompetitive antagonists at nicotinic receptors across cellular, physiological, and behavioral measures.

    “These drugs, including tricyclic antidepressants, selective serotonin reuptake inhibitors, and norepinephrine reuptake inhibitors, have been shown to act as noncompetitive nicotinic receptor (nAChR) antagonists on the cellular, physiologic, and behavioral level (Hennings et al., 1997;Fryer and Lukas, 1999;Lo ´pez-Valde ´s and García-Colunga, 2001).”

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.
