Indications

Agorest is used to treat major depressive disorder in adults. It is particularly suited to patients who have not responded to, or cannot tolerate, selective serotonin reuptake inhibitors (SSRIs). It is also used to prevent relapse of depression.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Agomelatine works on melatonin and serotonin receptors in the brain. It acts as an agonist at the MT1 and MT2 melatonin receptors and as an antagonist at the 5-HT2C serotonin receptor. Binding studies show that agomelatine does not affect monoamine uptake. It also has no affinity for alpha 1, alpha 2 and beta 3 adrenergic receptors, histaminergic, cholinergic, dopaminergic or benzodiazepine receptors.

In animal models of circadian rhythm disruption, agomelatine resynchronises the body clock. Its effect on the brain's chemistry is quite specific. It increases the release of noradrenaline and dopamine in the frontal cortex, but it has no influence on the extracellular levels of serotonin.

Pregnancy & Breastfeeding

Use in pregnancy: There's no clinical data yet on how agomelatine affects pregnant women, since human exposure hasn't been formally studied. Animal studies, however, haven't shown any direct or indirect harm to pregnancy, foetal or embryonal development, delivery, or development after birth. Even so, agomelatine should be prescribed to pregnant women only with caution.

Use in lactation: Whether agomelatine passes into human breast milk isn't known, though it and its breakdown products have been found in the milk of nursing rats. Because its effects on a breastfeeding baby haven't been established, breastfeeding should be stopped if treatment with agomelatine is judged necessary.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Dosage Reference

⚠️ Reference ranges from official sources only. Consult your doctor for personalized dosing.

Adults: The usual adult dose of agomelatine is 25 mg once a day, taken at bedtime. Taking it at night suits most people because agomelatine improves sleep quality without causing daytime drowsiness. You can take it with or without food. Most adults take one 25 mg tablet each day, usually just before bed. If you notice no improvement after two weeks, your doctor may increase the dose to 50 mg (two tablets) daily. The increase is for people who don't respond well to the lower dose, so don't raise it on your own. Use in children and adolescents Agomelatine should be given to anyone under 18 only on medical advice. It is not recommended for treating depression in patients under 18, because its safety and effectiveness have not been established in this age group. In clinical trials, children and adolescents taking other antidepressants showed more suicide-related behaviour (suicide attempts and suicidal thoughts) and more hostility (mostly aggression, oppositional behaviour and anger) than those given a placebo. Use in the elderly Agomelatine (25 to 50 mg per day) has been shown to work and to be safe in older patients with major depressive disorder (MDD) aged under 75 years. Its effectiveness has not been established in patients aged 75 and over, so agomelatine should not be used in that group.
