Topical glycopyrrolate formulations
Individually packaged topical formulations comprising about 0.25 to about 6% w/w of glycopyrrolate for the treatment of hyperhidrosis, wherein said wipe is contained within a pouch resistant to leakage. The formulations may further comprise ethanol, a buffering agent and water. In addition, the formulations may further comprise a polymer system comprising a hydrophobic polymer in combination with a hydrophilic polymer.
1. A topical formulation comprising:
about 0.25 to about 4% w/w of glycopyrronium bromide,
further comprising ethanol and water in a weight ratio of about 40:60 to about 60:40 and
a citric acid/sodium citrate buffering agent at an amount sufficient to maintain a pH of about 4 to 5.
2. The topical formulation of claim 1 , wherein the buffering agent maintains a pH of 4.5.
3. The topical formulation of claim 1 , wherein ethanol and water are in a weight ratio of about 50:50 to 60:40.
4. The topical formulation of claim 1 , wherein ethanol and water are in a weight ratio of about 60:40.
5. The topical formulation of claim 1 , wherein the ethanol is present in the amount of about 53.7 to about 57.3% w/w.
6. The topical formulation of claim 1 , wherein the buffering agent in the amount of about 0.2 to about 0.5% w/w.
7. The topical formulation of claim 1 , wherein the alcohol is present in the amount of about 53.7 to about 57.3% w/w, the buffering agent is present in the amount of about 0.2 to about 0.5% w/w and the water is added to 100% w/w.
8. The topical formulation of claim 3 , wherein the ethanol is present in the amount of about 53.7 to about 57.3% w/w, the buffering agent is present in the amount of about 0.2 to about 0.5% w/w and the water is added to 100% w/w.
9. The topical formulation of claim 1 , further comprising one or more optional additives selected from humectants, colorants, and perfumes.
10. An individually packaged wipe for the treatment of hyperhidrosis, comprising the topical formulation of claim 1 .
11. The individually packaged wipe of claim 10 , wherein the wipe is made of nonwoven material, paper material, woven material, knitted material, tufted material, stitch-bonded material incorporating binding yarns or filaments, or material felted by wet-milling.
12. The individually packaged wipe of claim 11 , wherein the wipe is made of nonwoven material.
13. The individually packaged wipe of claim 10 , wherein the wipe is folded.
14. The individually packaged wipe of claim 10 , wherein the wipe is contained within a pouch resistant to leakage.
15. The individually packaged wipe of claim 14 , wherein the pouch comprises an inner lining of linear low density polyethylene (LLDPE).
16. The individually packaged wipe of claim 14 , wherein the pouch comprises an inner lining of acrylonitrile-methyl acrylate copolymer (BAREX).
17. A method for alleviating hyperhidrosis in a mammal comprising the topical administration of the topical formulation of claim 1 to an area of the body such that the hyperhidrosis is reduced.
18. A method for alleviating hyperhidrosis in a mammal comprising the topical administration of the wipe of claim 10 to an area of the body such that the hyperhidrosis is reduced.
