Selective serotonin reuptake inhibitors (SSRIs) be a class of drugs wey be typically used as antidepressants insyd de treatment of major depressive disorder, anxiety disorders, den oda psychological conditions.
SSRIs primarily dey work by blocking serotonin reabsorption (reuptake) via de serotonin transporter, wey dey lead to gradual changes in brain signaling den receptor regulation, wey sam sanso dey interact plus sigma-1 receptors, particularly fluvoxamine, wich fi contribute to cognitive effects. Marketed SSRIs dey include six main antidepressants—citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, den sertraline—den dapoxetine, wich dem indicate for premature ejaculation. Dem approve fluoxetine for veterinary use insyd de treatment of canine separation anxiety.
SSRIs be de most widely prescribed antidepressants insyd chaw countries.[1] Insyd adults, dem be recommended as a first-line treatment give moderate to severe depression, while for mild depression non-drug treatments be preferred unless de patient choose medication.[2] SSRIs get modest benefits over placebo, plus uncertain clinical significance,[3] wey fi produce a substantial drug-specific response insyd a minority of patients per.[4] Der be no consistent evidence wey dey link depression to low serotonin levels, den long-term use fi reduce serotonin concentrations.[5] Fifty years after dema introduction, SSRIs remain widely used for depression, though dema effectiveness, mechanisms, den role insyd medicalizing normal life remain debated.[6]
Dema effectiveness, especially for mild to moderate depression, remain debated due to mixed research findings den concerns about bias, placebo effects, den adverse outcomes. SSRIs fi cause a range of side effects, wey dey include movement disorders like akathisia den various forms of sexual dysfunction—such as anorgasmia, erectile dysfunction, den reduced libido—plus sam effects wey potentially dey persist long after discontinuation (post-SSRI sexual dysfunction). SSRIs dey pose drug interaction risks by potentially dey cause serotonin syndrome, wey dey reduce efficacy plus NSAIDs, den dey alter drug metabolism thru CYP450 enzyme inhibition. SSRIs be safer in overdose dan tricyclics buh still fi cause severe toxicity in large anaa combined doses. Stopping SSRIs abruptly fi cause withdrawal symptoms, so tapering, especially from paroxetine, be recommended, wey fluoxetine dey cause fewer issues.
