Zafirlukast is FDA-approved for the prevention and treatment of asthma in adults and children older than 5 years old. [1] Like other leukotriene receptor antagonists, zafirlukast is thought to be useful for the long-term treatment of asthma, but it is generally less effective than inhaled glucocorticoids as monotherapy (which are the standard of care) or long-acting beta-2 agonists in ...
The medical uses for Cysteinyl-leukotriene type 1 receptor antagonists are for chronic and prophylactic treatment of asthma. [3] [9] [10] Other indications have been approved by the FDA for montelukast and they are used for the prevention of exercise-induced bronchoconstriction (EIB), relief of symptoms of allergic rhinitis (AR) that is for relief of seasonal allergic rhinitis and perennial ...
The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine [adrenaline], norepinephrine [noradrenaline], and dopamine), which function as both neurotransmitters and hormones. Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other ...
An antileukotriene, also known as leukotriene modifier and leukotriene receptor antagonist, is a medication which functions as a leukotriene-related enzyme inhibitor (arachidonate 5-lipoxygenase) or leukotriene receptor antagonist (cysteinyl leukotriene receptors) and consequently opposes the function of these inflammatory mediators; leukotrienes are produced by the immune system and serve to ...
Montelukast functions as a leukotriene receptor antagonist (cysteinyl leukotriene receptors) and consequently opposes the function of these inflammatory mediators; leukotrienes are produced by the immune system and serve to promote bronchoconstriction, inflammation, microvascular permeability, and mucus secretion in asthma and COPD.
Cromolyn Nedocromil. Mast cell stabilizers are medications used to prevent or treat certain allergic disorders. They block mast cell degranulation, stabilizing the cell and thereby preventing the release of histamine and related mediators.
The most serious side effect of Zyflo and Zyflo CR is a potential elevation of liver enzymes (in 2% of patients). Therefore, zileuton is contraindicated in patients with active liver disease or persistent hepatic function enzymes elevations greater than three times the upper limit of normal.
Arachidonate 5-lipoxygenase inhibitors are compounds that slow or stop the action of the arachidonate 5-lipoxygenase (5-lipoxygenase or 5-LOX) enzyme, which is responsible for the production of inflammatory leukotrienes.
