Montelukast was launched as Singulair in Mexico and Finland for the management of mild to moderate asthma inadequately controlled by inhaled corticosteroids and short-acting beta2-agonists. Montelukast can be obtained by an seven-step synthesis from 3-[2(E)-(7-chloroquinolin-2-yl)vinyl] benzaldehyde. Montelukast is a potent, selective and orally active antagonist of the CysLT1 (formerly called LTD4) receptor, thus blocking the effects of the cysteinyl leukotrienes LTC4, LTD4 and LTE4 on microvascular permeability and the activation of eosinophils.
Montelukast is suitable for relieving symptoms caused by allergic rhinitis
Montelukast is used for a number of conditions including asthma, exercise induced bronchospasm, allergic rhinitis, primary dysmenorrhoea and urticaria.
Montelukast is mainly used as a complementary therapy in adults in addition to inhaled corticosteroids, if they alone do not bring the desired effect.
Montelukast is also used to prevent allergic reactions and asthma flare-ups during the administration of intravenous immunoglobulin.
