Abstract

Abstract The present invention relates to a method of treating chronic or non-chronic respiratory disorders, consisting in administering to the patient by the oral, rectal or parenteral route, a medicament for dilating the bronchi, comprising as active ingredient at least one compound of formula I or one of its pharmaceutically acceptable salts: ##STR1## in which A represents O or S, R 1 , R 2 , R 3 , R 4 represent the hydrogen atom, an atom of halogen, an alkyl group with 1 to 4 carbon atoms or an alkoxy or alkenyloxy group, Z 1 and Z 2 represent an alkyl group or form with the nitrogen atom to which they are attached a saturated heterocyclic compound such as, in particular, pyrrolidine, piperidine, morpholine.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 73 words
A method of treating respiratory disorders consisting of administering an effective amount of a compound having the formula ##STR24## wherein R 1 , R 2 , R 3 , R 4 are selected from hydrogen, an atom of halogen, an alkyl group with 1 to 4 carbon atoms and an alkoxy group with 1 to 4 carbon atoms and R is an alkyl group with 1 to 4 carbon atoms, to said man.
Claim 2
Independent Claim 73 words
A method of treating respiratory disorders consisting of administering an effective amount of a compound having the formula ##STR24## wherein R 1 , R 2 , R 3 , R 4 are selected from hydrogen, an atom of halogen, an alkyl group with 1 to 4 carbon atoms and an alkoxy group with 1 to 4 carbon atoms and R is an alkyl group with 1 to 4 carbon atoms, to said man.
Claim 3
Dependent Claim 41 words
Method of treating respiratory disorders in man consisting in administering a medicament containing a therapeutically effective amount of at least one of the two stereoisomers of (2,3-dichloro-4-methoxy) phenyl-2-furyl O-(dimethylaminoethyl) ketone oxime or a pharmaceutically acceptable acid salt thereof to said man.
Claim 4
Dependent Claim 41 words
Method of treating respiratory disorders in man consisting in administering a medicament containing a therapeutically effective amount of at least one of the two stereoisomers of (2,3-dichloro-4-methoxy) phenyl-2-furyl O-(dimethylaminoethyl) ketone oxime or a pharmaceutically acceptable acid salt thereof to said man.
