Hello,
Welcome to healthcare magic.
1)
Deriphyllin is a
bronchodilator medicine (relaxes the airways), which is being used for treatment of asthma and COPD. Because of frequent side effects (commonly stomach upsets, palpitations, headaches etc.) and interaction with other drugs, this is not the first choice for treatment of
mild asthma. For mild asthma, first choice treatment is use of
salbutamol inhaler whenever required.
2)
Montelukast is a controller medicine which is to be taken regularly to prevent asthma attacks. It reduces inflammation of aiways, which is the cause for asthma. It can be taken alone or in combination with steroid inhalers depends on severity
3) Deriphyllin cannot be considered as a primary treatment of asthma
4) Montelukast is available as 4mg chewable tablets for children 2-6 year old, 5 mg chewable for 6-12 years and 10 mg tablets for adults and children above 12 years. The difference is in the dose.
Hope I have cleared your doubts
