Theophylline, a methylxanthine, is used to treat asthma. Explain the mechanism by which a theophylline can alleviate asthma symptoms resulting from bronchial constriction (think of a pathway cAMP is involved in).
Homework Answers
Theophylline helps in relaxing the smooth muscles which tightens to cause bronchial constriction. It also helps in relaxing pulmonary vessels & decreases the airway responsiveness towards adenosine, histamine, methacholine & allergen. The methylxanthine drug totally blocks type III & IV PDE (phosphodiesterase). PDE is an enzyme which breaks down cAMP in cells of the smooth muscles. Thus, an increased cAMP in the smooth muscles cells, helps in muscle relaxation.
hope the answer helps.

The drug hydroxyurea can be used to treat sickle cell anemia, although it is not often used because of undesirable side effects. Hydroxyurea is thought to function by stimulating the afflicted person’s synthesis of fetal hemoglobin. In a clinical study, patients who took hydroxyurea showed a 50% reduction in frequency of hospital admissions for severe pain, and there was also a decrease in the frequency of fever and abnormal chest X-rays. Why would this drug alleviate the symptoms of sickle...
