Figure 3. Benzbromarone relaxes an established leukotriene D4 (LTD4)-induced contraction in human airway smooth muscle.
Human airway smooth muscle was contracted with LTD4 (20nM) and then treated with cumulatively increasing concentrations of benzbromarone (Benzb) (10 μM, 50 μM, 100 μM) or vehicle (0.1% DMSO) at 30 minute intervals. Treatment with 10 μM, 50 μM and 100 μM benzbromarone resulted in significant relaxation (*p<0.05, **p<0.01, ***p<0.001, n=8 samples from 4 patients).
