Pranlukast Usage And Synthesis
Asthma drugsPranlukast is a common respiratory drug, it belongs to asthma drugs , it is the cysteinyl leukotrienes (LTs) receptor antagonist and it can bind to LTC4, LTD4, LTE4 receptors selectively to antagonize their effect . Roles and application are similar to zafirlukast. It is clinically used for the prevention of bronchial asthma. Oral 225mg once, 2 times one day, morning and evening after meal. After taking ,there may be gastrointestinal reactions,or there may be nausea, vomiting, abdominal pain, diarrhea or constipation, sometimes , fever, rash, pruritus and liver function abnormalities such as serum aminotransferase or bilirubin increase are visible . Pregnant women should use with caution , the elderly should take appropriate reductions. This product can not alleviate the onset of asthma.
At present, three leukotriene receptor antagonists are used for the following purposes:
1, zafirlukast :it is effective for mild to moderate asthma ,it can cause improvement in dose-dependent lung function, and reduce the amount of β agonists. Absorption of the product is affected by food, it should not be taken together with food. Oral each 20mg, 2 times/d.
2, montelukast: it is valid for intermittent or persistent asthma in adults and children. This product is approved by the FDA for the treatment of children aged 6 to 12. Absorption of the product is not affected by food, it can be taken with food . Oral each 10mg, once/d.
3, pranlukast :it is used for mild to moderate asthma, pranlukast can increase patients maximum expiratory flow,and improve asthma symptoms, it can be used as a daily treatment of chronic asthma. Each oral 450mg, 2 times/d.

Chemical PropertiesOff-white solid
UsesA potent, selective and orally active CysLT receptor antagonist. Leukotriene antagonist. Used as an antiasthmatic
Usesantiasthmatic;leukotriene receptor-1 antagonist
UsesLabeled Pranlukast, intended for use as an internal standard for the quantification of Pranlukast by GC- or LC-mass spectrometry.
Biological ActivitySelective cysteinyl leukotriene receptor 1 (CysLT 1 ) antagonist (IC 50 values are ~ 4-7 and 3620 nM for CysLT 1 and CysLT 2 respectively). Inhibits contraction of airway smooth muscle, microvascular leakage into airways and eosinophil infiltration. Can decrease symptoms of bronchial asthma.
