leukotriene receptor antagonists

Leukotriene receptor antagonists are medications that help prevent asthma and allergies by blocking the action of leukotrienes—substances in the body that can cause inflammation, bronchoconstriction, and mucus production. By inhibiting these compounds, these drugs help open airways, reduce swelling, and decrease mucus, leading to easier breathing and fewer allergy symptoms. Common examples include montelukast (Singulair). They are often used alongside other treatments for better control of asthma and allergic conditions.
