College Answer

Asthma drugs are typically categorised according to mechanism of action. A reasonable 
alternative is to categorise by clinical use, e.g. short acting, long acting, preventer, rescue etc. 
A lot of emphasis in marking was placed on an understanding of the beta-adrenergic pathway, 
its secondary messenger system and how this medicates smooth muscle relaxation.
Candidates whose answers had structure as well those who described the wide range of drugs 
used to treat asthma scored well.
