Here is a tough True/False/Not Given exercise for students aiming for IELTS band 7.5.
We will post the answers next week. Do your best and I hope this challenge will be a piece of cake!
The clinical guidelines in asthma therapy have now moved towards anti-inflammatory therapy – and away from regular bronchiodilator therapy – for all but the mildest asthmatics. This is now being reflected in prescribing patterns. In the U.S., combined prescription volumes of the major bronchiodilators peaked in 1991 (having risen slowly in the preceding years), though they still account for around half of the 65 million asthma prescriptions there. During the same period, prescriptions for inhaled steroids have doubled, but still account for less than 10% of asthma prescriptions in the U.S.
1. Only mild cases of asthma can be helped by anti-inflammatory therapy.
2. Use of bronchiodilators has been increasing since 1991.
3. Doctors are reluctant to treat asthma with inhaled steroids for fear of potential side-effects.
4. Bronchiodilators are the single most prescribed treatment for asthma.
