Patent Claims:	1. An anhydrous topical gel composition for treating, inhibiting or ameliorating excessive sweating, said composition comprising the following ingredients: (a) a compound of formula (2): said compound having the R stereoisomeric configuration at the 2 position and the R, S or RS stereoisomeric configuration at the 1′ and 3′ positions, or being a mixture thereof, said compound being present in an amount of from about 1% w/v or w/w to about 25% w/v or w/w of the composition; (b) anhydrous ethanol, present in an amount of at least 70% w/v or w/w of the composition; (c) hydroxypropyl cellulose; (d) one or more carriers or excipients, one of which is isopropyl myristate or C12-C15 alkyl lactate; and (e) citric acid; wherein said composition has a viscosity of about 100 to about 10,000 cps; and wherein propyl gallate and butylated hydroxytoluene (BHT) are absent from the composition. 2. The composition of claim 1, comprising from about 70% to about 85% w/w anhydrous ethanol. 3. The composition of claim 1, wherein at least one additional carrier or excipient is present. 4. The composition of claim 1, wherein the compound of formula (2) is selected from the group consisting of: (i) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; (ii) (2R)3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; (iii) (2R,3′R)3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; (iv) (2R,3′S)3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; (v) (2R,1′R,3′S)3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; (vi) (2R,1'S,3′S)3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; (vii) (2R,1′R,3′R)3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; and (viii) (2R,1'S,3′R)3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide. 5. The composition of claim 1, wherein the compound of formula (2) is at a concentration of from about 1% w/v or w/w to about 20% w/v or w/w of the composition. 6. The composition of claim 5, wherein the compound of formula (2) is at a concentration of from about 2% w/v or w/w to about 10% w/v or w/w. 7. The composition of claim 1, packaged into a multiple dose container that meters a dose of from about 0.5 ml to about 1.0 ml of the composition for each application. 8. The composition of claim 1, packaged into a single or unit dose container that delivers a single or unit dose of about 0.5 ml to about 1.0 ml of the composition for each application. 9. The composition of claim 1, wherein the compound of formula (2) is (2R,3′R)3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide. 10. The composition of claim 1, further comprising hexylene glycol. 11. The composition of claim 1, further comprising at least one member selected from the group consisting of dimethicone and cyclomethicone. 12. The composition of claim 1, further comprising a 6% silicone gum blend in dimethicone. 13. A method of treating a subject suffering from hyperhidrosis, said method comprising topically administering the composition as claimed in claim 1 to an area of skin of the subject before bedtime, such that, compared to untreated, baseline conditions, sweat production is reduced by at least 25% for at least six (6) hours. 14. The method of claim 13, wherein said composition is topically administered in a one to four times daily regimen to the area of skin of the subject. 15. The method of claim 13, wherein said composition is topically administered to the area of skin of the subject within 1-2 hours prior to the subject's sleep period. 16. A method of treating hyperhidrosis in a subject, said method comprising topically administering the composition of claim 1 to an affected skin area of the subject. 17. The method of claim 16, wherein said composition is topically administered in a one to four times daily regimen to the affected skin area of the subject. 18. The method of claim 16, wherein said composition is topically administered to the affected skin area of the subject within 1-2 hours prior to the subject's sleep period. 19. An anhydrous topical gel composition for treating, inhibiting or ameliorating excessive sweating, said composition comprising the following ingredients: (a) a compound of formula (2): said compound having the R stereoisomeric configuration at the 2 position and the R, S or RS stereoisomeric configuration at the 1′ and 3′ positions, or being a mixture thereof, said compound being present in an amount of from about 1% w/v or w/w to about 25% w/v or w/w of the composition; (b) anhydrous ethanol, present in an amount of at least 70% w/v or w/w of the composition; (c) hydroxypropyl cellulose; (d) one or more carriers or excipients, one of which is isopropyl myristate or C12-C15 alkyl lactate; and (e) citric acid.
