Blockers of leukotriene receptors such as monteleukast and zafirleukast block the action of leukotrienes on receptors on the bronchial smooth muscle to reduce bronchoconstiction. Also, they reduce the number of inflammatory cells in the area - thereby reducing inflammation and opening the airway more. They have fewer side effects than steroids, so they are preferred in children.

it can t be bronchoconstriction cause they talk about drugs that block leucotrienes receptorsLeucotrienes cause bronchoconstrictions for sure but anti-leucotrienes can t do the same.come on man THINK

dude u just posted previously that anti-leukotrienes are used in asthma. so yr answer should be A. :) come on man think!:)

asthma causes bronchoconstriction, and antileucotrines reverses this action. so leukotrien receptor blockers (another name for antileukotrines) is used to prevent A-Bronchoconstriction.:p

when patients develop serious side effects bue to excessive use of corticosteroids, we will give ziluetin to dec the dose of corticosteroids, but 1 thing is that ziluetin is nt as potent as beta agonists
