Answer to Question 1

1, 2, 3
The main actions of xanthine-derivative bronchodilators are to relax the smooth-muscle cells in the bronchi, directly produce diuresis of the kidneys, and stimulate the myocardium.

Answer to Question 2

Allopurinol has no analgesic or antiinflammatory properties and therefore is not beneficial in the treatment of acute gout.
