Title:	Formulation for soft anticholinergic analogs
Abstract:	Topical formulations comprising soft glycopyrrolates are useful for treating excessive sweating conditions in subjects, such as humans suffering from hyperhidrosis. Preferably, at least one soft anticholinergic agent is provided in an effective amount or concentration in an anhydrous formulation that can inhibit excessive perspiration resulting from a condition such as hyperhidrosis.

Patent Claims:	1. A topical anhydrous gel composition for administration to skin comprising the following ingredients: (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, present in an amount of at least about 70% w/w of the composition; (c) at least one gelling or viscosity-controlling ingredient; and (d) isopropyl myristate; (e) optionally, at least one additional carrier or excipient provided that said topical composition is an anhydrous gel and comprises from about 1% to about 25% w/w of the compound of formula (2), said anhydrous gel composition having greater storage stability compared to a composition comprising an aqueous solvent or aqueous buffer, with the proviso that said ingredients are present in amounts such that the product of any transesterification is the same as the compound of formula (2), and/or with the proviso that said anhydrous ethanol is present in an amount sufficient to act as a non-aqueous solvent for the compound of formula (2), and wherein the compound is delivered to sweat glands in the skin of an anatomic area selected from a hand palm area, a foot plantar area, a groin area, an axilla area, and a facial area of the subject. 2. The composition of claim 1, comprising from about 70% to about 99.99% w/w anhydrous ethanol. 3. The composition of claim 1, comprising from about 70% to about 85% w/w anhydrous ethanol. 4. The composition of claim 1, wherein at least one additional carrier or excipient is present. 5. The composition of claim 1, wherein the compound of formula (2) is selected from the group consisting of: (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. 6. 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. 7. The composition of claim 6, 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. 8. 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. 9. 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. 10. 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. 11. The composition of claim 1, wherein the gelling or viscosity-controlling ingredient is hydroxypropyl cellulose. 12. The composition of claim 1, further comprising citric acid. 13. The composition of claim 1, further comprising hexylene glycol. 14. The composition of claim 1, further comprising at least one member selected from the group consisting of dimethicone and cyclomethicone. 15. The composition of claim 4, further comprising a 6% silicone gum blend in dimethicone. 16. A method of treating hyperhidrosis in a subject, said method comprising topically administering a composition as claimed in claim 1 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, and wherein the compound is delivered to sweat glands in the skin of an anatomic area selected from a hand palm area, a foot plantar area, a groin area, an axilla area, and a facial area of the subject. 17. A method of treating hyperhidrosis in a subject, said method comprising topically administering a composition as claimed in claim 1 to skin of an area of a subject suffering from hyperhidrosis, 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, and wherein the compound is delivered to sweat glands in the skin of an anatomic area selected from a hand palm area, a foot plantar area, a groin area, an axilla area, and a facial area of the subject.
