Within the literature, four subtypes of such persistent forms are distinguished: (a) a continuing mild depressive mood (dysthymia), (b) a state meeting all criteria for major depression continuously (chronic major depression), (c) a recurrent major depression with incomplete remission between episodes, and (d) a superimposition of a major depressive episode on an antecedent dysthymia (double depression). This does not alter the authors' adherence to PLOS ONE policies on sharing data and materials.ĭuring their lifetime, approximately 3% to 6% of the adults in Western countries suffer from a form of depression that persists for at least two years.

The comparative evidence for further agents was insufficient or lacking. Patients treated with the antipsychotic amisulpride were more likely to manifest weight gain and endocrine adverse events.

SSRIs primarily showed gastrointestinal adverse events. TCAs were primarily associated with (anti-)cholinergic and sedating adverse events. The complementary treatment with acetyl-l-carnitine showed lower rates of experiencing any adverse event and related discontinuations than all other comparators. Pairwise comparisons among the substance classes revealed that more patients receiving TCAs or SNRIs experienced any adverse event and that more patients receiving TCAs or the SARI trazodone discontinued treatment. The odds of experiencing any adverse event were significantly higher for TCAs and serotonin noradrenaline reuptake inhibitors (SNRIs) compared to placebo. Almost all analyzed substance classes were associated with higher discontinuation rates than placebo including tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), monoamine oxidase inhibitors (MAOIs), antipsychotics, and the serotonin antagonist and reuptake inhibitor (SARI) trazodone. Thirty-four studies that comprised 4,769 patients and examined 20 individual agents in nine substance classes were included. We analyzed the data using traditional and network meta-analyses. Outcomes were the incidence of experiencing any adverse event, specific adverse events and related treatment discontinuations. We conducted a systematic electronic search and included randomized controlled trials that investigated antidepressants for the treatment of PDD in adults.

We aimed to compare the safety of antidepressants for the treatment of persistent depressive disorder (PDD) with each other and with placebo.
