Abstract

Amitriptyline is a commonly prescribed tricyclic antidepressant, which has been shown to impair mitochondrial function and increase oxidative stress in a variety of in vitro assays. Coenzyme Q(10) (CoQ(10)), an essential component of the mitochondrial respiratory chain and a potent antioxidant, has been proposed as a mitochondrial dysfunction marker. In order to evaluate the putative mitochondrial toxicity of amitriptyline, we have analyzed CoQ(10) and ATP levels, oxidative damage and mitochondrial mass in peripheral blood cells from control healthy volunteers and psychiatric patients with depressive episodes treated or non-treated with amitriptyline. In patients not following amitriptyline treatment, CoQ(10) and ATP levels and mitochondrial mass were reduced when compared to normal individuals while lipid peroxidation was clearly increased. All these alterations were aggravated in patients following oral amitriptyline therapy. These results suggest that mitochondrial dysfunction could be involved in the pathophysiology of depression and may be worsened by amitriptyline treatment. CoQ(10) supplementation is postulated to counteract the adverse effects of amitriptyline treatment in psychiatric patients.

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.
