Common therapeutic uses

Treatment of asthma, bronchial asthma, and bronchospasm associated with obstructive airway diseases. May be used as adjunctive therapy when standard treatments are insufficient.

As a xanthine derivative, it acts as a phosphodiesterase inhibitor, leading to increased levels of cyclic AMP in bronchial smooth muscle cells, which results in bronchodilation. May also have some anti-inflammatory properties.

May interact with other xanthine derivatives, certain antibiotics, and cardiovascular medications. Common side effects may include gastrointestinal discomfort, headache, and tachycardia. Dosage must be individualized and therapeutic drug monitoring may be required. Contraindicated in patients with active peptic ulcers and certain cardiac conditions.
