Step 1
These drugs mimic the effects of substances such as adrenaline and noradrenaline, which are produced naturally by the body. They can help to relax and open up the airways in people with conditions such as asthma. Show more…

The respiratory symptoms of asthma result from constriction of the bronchi and bronchioles of the lungs, caused by contraction of the smooth muscle of their walls. This constriction can be reversed by raising [cAMP] in the smooth muscle. Explain the therapeutic effects of albuterol, a $\beta$ -adrenergic agonist taken (by inhalation) for asthma. Would you expect this drug to have any side effects? If so, how might one design a better drug that does not have these effects?
A. Increase alertness B. Pupilary constriction C. Piloerection D. Increase heart rate E. Increase respiratory rate F. Sweating Which of the above are effects of adrenaline/Noradrenaline? (a) All except C (b) All except $\mathrm{B}$ and $\mathrm{F}$ (c) All except B (d) All except $\mathrm{B}, \mathrm{E}$ and $\mathrm{F}$
