Substituted 8-phenylxanthines and their use as bronchodilators are described. Processes for their preparation and use as well as pharmaceutical compositions containing them are also described. The novel compounds have the following formula:
wherein each of R and R1, which are the same or different, is e.g. a hydrogen atom or an alkyl radical having from to six carbon atoms; the dashed lines mean that the one or two optional substituents may only be in the three and/or four positions; X is e.g. a hydrogen atom; and Y e.g. is OH or an amino group, which amino group may be substituted in a specific way; or a pharmaceutically acceptable salt thereof; with the proviso that the compound 8-(4-sulfophenyl)-theophylline is excluded.
