Singulair

(Montelukast Sodium)

PreclinicalSmall molecule

Montelukast is used to prevent and treat asthma symptoms and to relieve nasal congestion from allergies. It works by blocking substances in the body that cause inflammation and narrowing of airways.[1] Singulair is currently being investigated across 3 indications[3], with its most advanced program in Preclinical.[1]

Singulair is one of 57 small molecule programs targeting Rhinitis, Allergic, Perennial. It is currently in Preclinical.
