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.

DescriptionPranlukast, a novel chromone derivative, was introduced in Japan for the treatment of bronchial asthma and allergic diseases. Pranlukast is a highly potent, selective and competitive antagonist of peptidoleukotrienes with high affinity for the LTD4 receptor. In patients with bronchial asthma, pranlukast was reported to induce significant improvement in both immediate and late asthmatic response induced by antigen. Pranlukast is also being evaluated clinically for the treatment of perennial allergic rhinitis, pediatric asthma, and cutaneous pruritus in dialysis patients. The therapeutic potential of pranlukast in managing irritable bowel syndrome has been suggested.
