Abstract

The present invention provides compositions and methods for administering oxybutynin while minimizing the incidence and or severity of adverse drug experiences associated with oxybutynin therapy. In one aspect, these compositions and methods provide a lower plasma concentration of oxybutynin metabolites, such as N-desethyloxybutynin, which is presumed to be contributing at least in part to some of the adverse drug experiences, while maintaining sufficient oxybutynin plasma concentration to benefit a subject with oxybutynin therapy. The invention also provides isomers of oxybutynin and its metabolites that meet these characteristics of minimized incidence and/or severity of adverse drug experiences, and maintenance of beneficial and effective therapy for overactive bladder.

Claims

1. A method of treating with oxybutynin a human subject having overactive bladder, while minimizing an anticholinergic or antimuscarinic adverse drug experience associated with said oxybutynin treatment therapy comprising the step of:

administering as a transdermal patch, a composition comprising oxybutynin to said subject for a duration of from about 24 to about 96 hours to provide a plasma area under the curve (AUC) ratio of oxybutynin to an oxybutynin metabolite of from about 0.5;

1 to about 5;

1, wherein the transdermal patch optionally includes a permeation enhancer.

3. The method of either claim 1 or 2, wherein the AUC ratio of oxybutynin to an oxybutynin metabolite is from about 1:

1 to about 5;

1.

4. The method of claim 3, wherein the AUC ratio of oxybutynin to an oxybutynin metabolite is from about 0.8:

1 to about 1.5;

1.

5. The method of either claim 1 or 2, wherein the metabolite of oxybutynin is N-desethyloxybutynin.

6. The method of claim 5, wherein the N-desethyloxybutynin is (R)-N-desethyloxybutynin, (S)-N-desethyloxybutynin or a combination thereof.

7. The method of either claim 1 or 2, wherein the oxybutynin is a mixture of R-oxybutynin and S-oxybutynin.

9. The method of either claim 1 or 2, wherein the duration of administration is between 72 and 96 hours.

10. The method of claim 9, wherein the duration of administration is 72 hours 11. The method of claim 9, wherein the duration of administration is 84 hours.

12. The method of claim 9, wherein the duration of administration is 96 hours.

2. A method of treating with oxybutynin a human subject having overactive bladder, while minimizing an anticholinergic or antimuscarinic adverse drug experience associated with said oxybutynin treatment therapy comprising the step of:

administering as a transdermal patch, a composition comprising oxybutynin to said subject for a duration of up to 96 hours to provide a plasma area under the curve (AUC) ratio of oxybutynin to an oxybutynin metabolite of from about 0.5;

1 to about 5;

1, wherein the transdermal patch optionally includes a permeation enhancer.

8. The method of claim 8, wherein the oxybutynin is R-oxybutynin.

13. An article of manufacture for transdermal application comprising:

a transdermal patch including a composition of oxybutynin and optionally a permeation enhancer for administration to a human subject, wherein the patch provides, upon administration to said subject for a duration of from about 24 to about 96 hours, a plasma AUC ratio of oxybutynin to an oxybutynin metabolite from about 0.5;

1 to about 5;

1, and wherein said patch minimizes an anticholinergic or antimuscarinic adverse drug experience associated with the administration of oxybutynin.

15. The article of manufacture of either claim 13 or 14, wherein the AUC ratio of oxybutynin to an oxybutynin metabolite is from about 1:

1 to about 5;

1.

16. The article of manufacture of claim 15, wherein the AUC ratio of oxybutynin to an oxybutynin metabolite is from about 0.8:

1 to about 1.5;

1.

17. The article of manufacture of either claims 13 or 14, wherein the metabolite of oxybutynin is N-desethyloxybutynin.

18. The article of manufacture of claim 17, wherein the N-desethyloxybutynin is (R)-N-desethyloxybutynin, (S)-N-desethyloxybutynin or a combination thereof.

19. The article of manufacture of either claim 13 or 14, wherein the oxybutynin is a mixture of R-oxybutynin and S-oxybutynin.

20. The article of manufacture of claim 19, wherein the oxybutynin is R-oxybutynin.

21. The article of manufacture of either claim 13 or 14, wherein the duration of administration is between 72 and 96 hours.

22. The article of manufacture of claim 21, wherein the duration of administration is 72 hours.

23. The article of manufacture of claim 21, wherein the duration of administration is 84 hours.

24. The article of manufacture of claim 21, wherein the duration of administration is 96 hours.

14. An article of manufacture for transdermal application comprising:

a transdermal patch including a composition of oxybutynin and optionally a permeation enhancer for administration to a human subject, wherein the patch provides, upon administration to said subject for a duration of up to 96 hours, a plasma AUC ratio of oxybutynin to an oxybutynin metabolite from about 0.5;

1 to about 5;

1, and wherein said patch minimizes an anticholinergic or antimuscarinic adverse drug experience associated with the administration of oxybutynin.
