Key differences
Elavil belongs to Antidépresseurs while Singulair belongs to Médicaments respiratoires. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Elavil: L'amitriptyline inhibe la recapture de la sérotonine et de la noradrénaline au niveau des synapses centrales. Singulair: Le montélukast bloque sélectivement le récepteur CysLT1, qui médie l'action des leucotriènes C4, D4 et E4 — médiateurs pro-inflammatoires libérés par les mastocytes et les éosinophiles.
When Elavil is preferred
L'amitriptyline est autorisée dans la dépression caractérisée, mais son usage contemporain est dominé par les indications hors AMM à faible dose : douleurs neuropathiques, fibromyalgie, céphalées de tension chroniques, prévention de la migraine, syndrome de l'intestin irritable…
When Singulair is preferred
Singulair est autorisé chez l'adulte et l'enfant dans le traitement de fond de l'asthme, y compris le bronchospasme d'effort, et dans le traitement de la rhinite allergique saisonnière et perannuelle lorsque les traitements conventionnels sont insuffisants ou mal tolérés.
