An acute asthma attack is usually treated with bronchodilators
to reduce the constriction of the airways. Intravenous adrenalin
and theophylline are often given in emergency rooms for this
purpose, if short-acting bronchodilators given by nebulizer
haven't sufficiently controlled the attack.
Once the acute attack is over, anti-inflammatories may be used to
reduce the inflammation of the airways. Inhaled steroids are
usually the first choice, but for a sufficiently severe attack,
oral steroids such as prednisone may also be given.
