Pharmacokinetics
Well-absorbed orally, ~44% bioavailability. Metabolized hepatically via CYP3A4/CYP2C19/CYP2D6 to N-desmethylsertraline (less active). Half-life ~26h; steady state in ~1 week.
Pharmacodynamics
Highly selective inhibitor of the serotonin reuptake transporter (SERT). Mild dopamine reuptake inhibition at higher doses. Minimal affinity for muscarinic, histaminic, or adrenergic receptors — hence cleaner adverse effect profile than TCAs.
Indications
- Major depressive disorder
- Generalized anxiety disorder
- Obsessive-compulsive disorder
- Post-traumatic stress disorder
- Panic disorder
- Premenstrual dysphoric disorder
Dosing and titration
Start 25–50 mg PO daily. Titrate by 25–50 mg every 1–2 weeks based on response. Typical effective dose 50–200 mg/day; max 200 mg/day.
Effects
Therapeutic: improved mood, reduced anxiety, fewer obsessive thoughts (delayed 2–4 weeks).
Common adverse: nausea, diarrhea, sexual dysfunction, insomnia, somnolence, sweating.
Adverse effects
Serotonin syndrome (especially with other serotonergic agents), QT prolongation at high doses, hyponatremia (SIADH, esp. elderly), bleeding risk, suicidality warning in young adults, discontinuation syndrome.
Contraindications
MAOIs (within 14 days), pimozide, severe hepatic impairment. Caution: bipolar disorder (mood switching risk), seizure disorders.
Interactions
MAOIs (serotonin syndrome — contraindicated), triptans, tramadol, linezolid, lithium, NSAIDs/anticoagulants (bleeding), CYP2D6 substrates.
Pregnancy and lactation
Category C. SSRIs in third trimester associated with persistent pulmonary hypertension of the newborn (PPHN) and neonatal adaptation syndrome. Risk-benefit decision; sertraline often preferred in pregnancy among SSRIs.
Monitoring
Mood/suicidality (especially first 4 weeks), sodium (elderly), QT in cardiac risk, response and side effects.
Patient counseling
Take with or without food. Effect emerges over 2–4 weeks. Don't stop abruptly — taper to avoid withdrawal. Report serotonin-syndrome symptoms.
