Clinical Significance

Used in monitoring levels of theophylline to ensure proper therapy and in diagnosis and treatment of theophylline overdose.

Theophylline is a methylxanthine derivative that is widely used in the treatment of asthma, obstructive lung disease and neonatal apnea. The primary therapeutic effect of theophylline is due to relaxation of bronchial smooth muscle; however theophylline has a variety of other effects. These include stimulation of the central nervous system and medullary respiratory centers, decreased peripheral vascular resistance, cardiac stimulation, and diuresis.
