Patent Claims:	1. A racemic mixture of (R)-3-((S)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate and (S)-3-((R)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate. 2. An absorbent pad comprising a pharmaceutically acceptable solution comprising a racemic mixture of (R)-3-((S)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate and (S)-3-((R)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate and at least one pharmaceutically acceptable additive. 3. The absorbent pad of claim 2, wherein one pharmaceutically acceptable additive is ethanol. 4. The absorbent pad of claim 2, wherein the weight percent of said racemic mixture of (R)-3-((S)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate and (S)-3-((R)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate in said pharmaceutically acceptable solution is between 1% and 6%; and the pH of said pharmaceutically acceptable solution is between 3.5 and 5.5. 5. The absorbent pad of claim 2, wherein the absorbent pad comprises polypropylene. 6. The absorbent pad of claim 2, wherein the absorbent pad is nonwoven 100% polypropylene. 7. The absorbent pad of claim 2, wherein the absorbent pad is sealed in a pouch. 8. The absorbent pad of claim 7, wherein the pouch is a laminate containing aluminum foil as a layer. 9. A pharmaceutically acceptable solution comprising a racemic mixture of (R)-3-((S)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate and (S)-3-((R)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate and at least one pharmaceutically acceptable additive. 10. The pharmaceutically acceptable solution of claim 9, wherein one pharmaceutically acceptable additive is ethanol. 11. The pharmaceutically acceptable solution of claim 9, wherein the weight percent of said racemic mixture of (R)-3-((S)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate and (S)-3-((R)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate is between 1% and 6%; and the pH of said pharmaceutically acceptable solution is between 3.5 and 5.5. 12. A method of treating hyperhidrosis comprising topically administering a therapeutically effective amount of a pharmaceutically acceptable solution of a racemic mixture of (R)-3-((S)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate and (S)-3-((R)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate to the skin of a mammal. 13. The method of claim 12, wherein said mammal is human. 14. The method of claim 13, wherein said pharmaceutically acceptable solution is applied to the axilla. 15. The method of claim 13, wherein said pharmaceutically acceptable solution is applied to the hands. 16. The method of claim 13, wherein said pharmaceutically acceptable solution is applied to the feet. 17. The method of claim 13, wherein said pharmaceutically acceptable solution is applied to the groin, face, back, or abdomen. 18. The method of claim 12, where the administration is with an absorbent pad comprising an absorbed pharmaceutically acceptable solution of a racemic mixture of (R)-3-((S)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate and (S)-3-((R)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate. 19. The method of claim 14, where the administration is with an absorbent pad comprising an absorbed pharmaceutically acceptable solution of a racemic mixture of (R)-3-((S)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate and (S)-3-((R)-2-cyclopentyl-2-hydroxy-2-phenylacetoxy)-1,1-dimethylpyrrolidi- nium 4-methylbenzenesulfonate. 20. The method of claim 12, wherein one pharmaceutically acceptable additive is ethanol. 21. The method of claim 14, wherein one pharmaceutically acceptable additive is ethanol. 22. The method of claim 18, wherein one pharmaceutically acceptable additive is ethanol. 23. The method of claim 22, wherein the pharmaceutically acceptable solution comprises between about 57 and 59.5% by weight dehydrated ethanol. 24. The method of claim 22, wherein the pH of said pharmaceutically acceptable solution is between about 4.0 and about 5.0. 25. The method of claim 22, wherein the pH of said pharmaceutically acceptable solution is between about 4.0 and about 4.7. 26. The method of claim 22, wherein the pH of said pharmaceutically acceptable solution is between about 4.1 and about 4.6. 27. The method of claim 22, wherein said pharmaceutically acceptable solution is clear and colorless or pale yellow at a pH of between about 4.0 and about 5.0 at 25.degree. C.
