Introduction to Zafirlukast
Zafirlukast is an orally active and selective cysteinyl leukotriene (cysLT) receptor antagonist, primarily used for the prophylaxis and treatment of chronic asthma. It works by blocking the effects of leukotrienes, which are chemicals that cause inflammation in the airways.
Clinical Trials and Efficacy
Mechanism of Action
Zafirlukast antagonizes the effects of exogenously administered LTD4 and cysLTs released endogenously in response to physical and chemical stimuli. It inhibits LTD4-induced bronchoconstriction, with effects still evident 12 hours after drug administration[3][4].
Clinical Outcomes
In multicenter trials involving patients with chronic, stable asthma, zafirlukast has been shown to reduce asthma symptoms, decrease the use of as-needed beta-agonist therapy, and improve pulmonary function. These improvements were observed without an increase in adverse events[3][4].
Comparative Studies
Zafirlukast has been compared to other treatments in clinical studies. It was found to be as effective as doubling the dosage of inhaled corticosteroids and similar in efficacy to pranlukast 225 mg twice daily. However, inhaled fluticasone propionate and salmeterol have shown greater clinical improvement than zafirlukast in some studies[1].
Safety Profile
Clinical trials have demonstrated that zafirlukast has an adverse event profile similar to that of placebo. However, isolated reports of hepatic dysfunction in a small number of patients have been noted, and recommendations for monitoring patients are in place. There is no established causal relationship between zafirlukast and Churg-Strauss Syndrome, but patients undergoing corticosteroid dosage reductions require careful surveillance[1].
