Ketotifen Fumarate Clinical Application:

It has been more than 20 years since ketotifen fumarate have been applied to the prevention and treatment of asthma and childhood asthma. It is a kind of drug with dual effect of both prevention and treatment in the prevention and treatment of asthma and childhood asthma. It should be particularly noted that ketotifen had ever taken as the long-term controlling drug of asthma and childhood long-term asthma and was subject to wide application in many countries. Since the early 1980s, ketotifen fumarate had already been applied in Western Europe, Asia, and our country for the prevention and treatment of asthma and asthma in children. But since entering into 21st century, the annual applied amount has decreased year by year. Because of its side effect of inhibition of the central nervous system, its oral tablet currently has still not approved by the FDA and thus failing to enter the US market with only ketotifen fumarate eye drops (ZADITOR) had been approved by the FDA in 1999. Recent studies have also shown the effectiveness of ketotifen asthma still demands further studies. Moreover, ketotifen fumarate has several additional advantages. First, it can cause sleepiness of the schoolchildren and thus being able to affect their academic performance; second, it can also do harm to the mental development of infants and young children. Thirdly, it is also be able to affect the metabolism of sustained-release tea and thus negatively affecting its anti-inflammatory effects of theophylline. For all the above points, it is not recommended by the GINA (affiliated organization of WHO) to apply ketotifen fumarate for the treatment and prevention of asthma and childhood asthma. But from the perspective of clinical economics, ketotifen fumarate is a suitable anti-allergic drug for being applied in developing countries and rural areas for treating asthma and childhood asthma with certain efficacy due to its relative low price.
