responses may be correct. therapy is used to reduce airway responsiveness to
prevent the occurrence of asthma attacks. This therapy
is used every day, regardless of symptoms. Reliever
drugs are indicated when symptoms of
an attack occur to decrease the duration and severity of
the attack. Long-acting beta agonists do not act quickly
enough to relieve acute symptoms; they are indicated
for their long-term impact on symptoms. Anti-
inflammatory drugs decrease
inflammation and can be beneficial in the treatment of
asthma; however, they do not cause bronchodilation.

with neutropenia, which greatly increases the risk for
infection, is the major dose-limiting side effect of
chemotherapy for lung cancer.

turpentine, and tartaric acid does not pose this risk.
