Key differences
Singulair belongs to Respiratory Medications while Addyi belongs to Women's Sexual Health. 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
Singulair: Montelukast selectively blocks the CysLT1 receptor, which mediates the action of leukotrienes C4, D4 and E4 — proinflammatory mediators released by mast cells and eosinophils. Addyi: Sexual desire is modulated by complex central nervous system pathways involving serotonin (generally inhibitory) and dopamine and norepinephrine (generally excitatory).
When Singulair is preferred

When Addyi is preferred
Addyi is indicated for the treatment of acquired, generalised hypoactive sexual desire disorder (HSDD) in premenopausal women.
