Patent Claims:	1. A method of treating hyperhidrosis in a subject, said method comprising topically administering an anhydrous topical gel composition to skin of an area of a subject suffering from hyperhidrosis, before bedtime, such that, compared to untreated, baseline conditions, sweat production is reduced by at least 25% for at least six (6) hours; and such that sweat production is reduced by an amount substantially equivalent to an amount that sweat production is reduced as compared to untreated, baseline conditions, following administration of a composition comprising the same concentration of glycopyrrolate, and with an improved safety profile compared to topical glycopyrrolate, wherein said anhydrous topical gel composition comprises: (a) a compound having the formula: 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; (b) anhydrous ethanol; (c) at least one gelling or viscosity-controlling ingredient; (d) optionally, at least one additional carrier or excipient; and (e) isopropyl myristate; provided that said anhydrous topical gel composition comprises from about 1% to about 25% of the compound of formula (2), said composition having greater storage stability compared to a composition comprising an aqueous solvent or aqueous buffer, wherein the gelling or viscosity-controlling ingredient comprises hydroxypropyl cellulose, and wherein said anhydrous topical gel composition further comprises citric acid and hexylene glycol. 2. The method of claim 1, wherein said anhydrous topical gel composition comprises at least one additional carrier or excipient is present. 3. The method 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. 4. The method of claim 1, wherein said anhydrous topical gel composition comprises the compound of formula (2) at a concentration of from about 1% to about 20%. 5. The method of claim 4, wherein said anhydrous topical gel composition comprises the compound of formula (2) at a concentration of from about 2% to about 10%. 6. The method of claim 1, wherein said anhydrous topical gel composition is packaged in 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. 7. The method of claim 1, wherein said anhydrous topical gel composition is packaged in 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. 8. The method 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. 9. The method of claim 4, wherein the compound of formula (2) is (2R, 3′R) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide. 10. The method of claim 5, wherein the compound of formula (2) is (2R, 3′R) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide. 11. The method of claim 6, wherein the compound of formula (2) is (2R, 3′R) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide. 12. The method of claim 7, wherein the compound of formula (2) is (2R, 3′R) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide. 13. The method of claim 1, wherein said anhydrous topical gel composition further comprises DIMETHICONOL BLEND 20. 14. The method of claim 1, wherein a dose of from about 0.5 ml to about 2.0 ml is applied.
