The present invention is directed to a group of compounds which are imidazo[2,1-b]quinazolin-5(3H)-ones, related tricyclic compounds, and pharmaceutically acceptable salts thereof. These compounds are useful as bronchodilators. These compounds are prepared by the reaction of an appropriate hydrazine with an appropriate 1-substituted-2-methyl-2-imidazoline or chemically equivalent compound.
