Beneficial effect of combination therapy with ozagrel and pranlukast in exercise-induced asthma demonstrated by krypton-81 m ventilation scintigraphy--a case report.
BACKGROUND
We evaluated the effect of combination therapy with thromboxane A2 synthesis inhibitor and leukotriene receptor antagonist in a patient with exercise-induced asthma using krypton-81 m ventilation scintigraphy.


METHODS
In a patient with exercise-induced asthma, we found exercise-induced abnormalities of respiratory function test and ventilation scintigraphy, and increases in plasma concentrations of thromboxane B2 and leukotriene C4 with exercise.


METHODS
A thromboxane A2 synthesis inhibitor (ozagrel) and a leukotriene receptor antagonist (pranlukast) were prescribed.


RESULTS
After treatment for 2 weeks, abnormalities of respiratory function test and ventilation scintigraphy improved.


CONCLUSIONS
The combination therapy with ozagrel and pranlukast might be useful for the relief of symptoms in patients with exercise-induced asthma, and krypton-81 m ventilation scintigraphy could be a useful tool for visible evaluation of treatment.
