Zafirlukast inhibits the motion of CYP3A4, resulting in drug-drug interactions with other medicines which are metabolized by CYP3A4. Genetic differences in LTC4 synthase and CYP2C9 may well predict how somebody reacts to zafirlukast remedy.

Metabolism Zafirlukast is extensively metabolized. The most typical metabolic solutions are hydroxylated metabolites that are excreted while in the feces. The metabolites of zafirlukast discovered in plasma are a minimum of 90 instances considerably less strong as LTD four Sulforaphane receptor antagonists than zafirlukast in a normal in vitro exam of exercise. In vitro research making use of human liver microsomes showed that the hydroxylated metabolites of zafirlukast excreted inside the feces are formed with the cytochrome P450 2C9 (CYP2C9) pathway.

Hepatic impairment: Zafirlukast utilization is not really advised for people with hepatic impairment as a result of compromised hepatic clearance, causing a fifty% to sixty% boost in the maximum plasma concentration.
