Abstract

Active compound combinations of compounds of group A, particularly opioids such as (+)-(2R,3R)-1-dimethylamino-3-(3-methoxy-phenyl)-2-methyl-pentan-3-ol or a salt thereof with a physiologically tolerated acid, and compounds of group B, particularly anti-muscarine agents such as oxybutynin or a salt thereof with a physiologically tolerated acid suitable for treatment of an increased urge to urinate or urinary incontinence. Related pharmaceutical formulations and methods of treatment of an increased urge to urinate or urinary incontinence are also provided.

Claims (7)

1. A composition of matter comprising as an admixture (+)-(2R,3R)-1-dimethylamino-3-(3-methoxy-phenyl)-2-methyl-pentan-3-ol or a salt thereof with a physiologically tolerated acid and oxybutynin or a salt thereof with a physiologically tolerated acid at dosages that provide a synergistic effect for the treatment of urinary incontinence.

2. The composition of matter of claim 1 , wherein one or more of (+)-(2R,3R)-1-dimethylamino-3-(3-methoxy-phenyl)-2-methyl-pentan-3-ol and oxybutynin is present in the form of a free base.

3. The composition of matter of claim 1 , wherein oxybutynin is present in the form of an isolated enantiomer.

4. The composition of matter of claim 1 , wherein oxybutynin is present in the form of a mixture of stereoisomers.

5. The composition of matter of claim 4 , wherein oxybutynin is present in the form of a racemic mixture.

6. The composition of matter of claim 1 , wherein (+)-(2R,3R)-1-dimethylamino-3-(3-methoxy-phenyl)-2-methyl-pentan-3-ol is in the form of a hydrochloride salt.

7. A pharmaceutical formulation comprising as an active compound combination a composition of matter according to claim 1 and at least one pharmaceutically suitable additive or auxiliary substance.
