PGE1 alcohol is a non-irritant bronchodilator, with relaxant activity on the human bronchial muscle in vitro, comparable to PGE1 at concentrations of 0.01 to 10.0 µg/ml.1,2 PGE1 alcohol binds to the mouse recombinant EP3 and EP4 receptors with Ki values of 330 and 190 nM, respectively.3 Asthmatics receiving single dose inhalation treatments reported significant but short-acting bronchodilation at doses of 10 and 30 µg.1
