Ambien and Singulair are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.
Key differences
Ambien belongs to Sleep Aids and Hypnotics while Singulair belongs to Respiratory Medications. 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
Ambien: Zolpidem is a positive allosteric modulator of the GABA-A receptor with relative selectivity for the alpha-1 subunit, which is associated with sedation and sleep induction. 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.
When Ambien is preferred
Ambien is approved in adults for the short-term treatment of insomnia, typically when difficulty falling asleep or maintaining sleep is associated with daytime impairment.
When Singulair is preferred
Singulair is approved in adults and children for the maintenance treatment of asthma, including exercise-induced bronchospasm, and for the treatment of seasonal and perennial allergic rhinitis when conventional therapy is insufficient or not tolerated.
