Pharmacokinetics：

Pranlukast 225mg orally, about 3 hours after the peak blood concentration, the effect can last for 12 hours. Fasting drug is absorbed faster than postprandial drug. Plasma protein binding rate of Prenast > 99%.

Nocturnal administration has higher bioavailability than early morning administration, so it is suitable for bedtime administration. It can be used as a daily medication to treat asthma. Age had no significant effect on drug metabolism.

Anti-asthma effect：

Both animal studies and human studies have shown that Prenast can effectively inhibit airway constriction induced by leukotriene, and can not antagonize airway constriction induced by histamine and acetylcholine, indicating that prenast is a specific leukotriene receptor antagonist. It is also effective for cold air induced bronchoconstriction and aspirin induced asthma.
