Method for treating hyperhidrosis with dexmecamylamine
The present invention relates to dexmecamylamine and the use of dexmecamylamine, substantially free of exo-R-mecamylamine, in the treatment of hyperhidrosis.
1. A method of treating hyperhidrosis, the method comprising the administration of a therapeutically effective amount of dexmecamylamine or a pharmaceutically acceptable salt thereof, substantially free of exo-R-mecamylamine, to a subject with hyperhidrosis, wherein the administration is intravenous, intramuscular, subcutaneous, intraperitoneal, intraarterial, transdermal, intrathecal, intracerebroventricular, rectal, inhalatory, topical, oral, buccal, sublingual, intranasal, or by way of bolus injection or powder injection.
2. The method according to claim 1 , wherein the hyperhidrosis is primary hyperhidrosis.
3. The method according to claim 1 , wherein the subject is a human.
4. The method according to claim 1 , wherein the dexmecamylamine or pharmaceutically acceptable salt thereof is administered once daily.
5. The method according to claim 1 , wherein the dexmecamylamine or pharmaceutically acceptable salt thereof is administered more than once daily.
6. The method according to claim 1 , wherein hyperhidrosis is axillary, palmoplantar, face/scalp, or generalized.
7. The method according to claim 1 , wherein the hyperhidrosis is palmoplantar.
8. The method according to claim 1 , wherein the hyperhidrosis is secondary hyperhidrosis.
9. The method according to claim 1 , wherein the hyperhidrosis is secondary to spinal cord injury.
10. The method according to claim 1 , wherein the hyperhidrosis results from increased sympathetic cholinergic activity.
11. The method according to claim 1 , wherein the dexmecamylamine or pharmaceutically acceptable salt thereof is orally administered in an amount of about 0.5 mg.
12. The method according to claim 1 , wherein the dexmecamylamine or pharmaceutically acceptable salt thereof is orally administered in an amount of about 1.0 mg.
13. The method according to claim 1 , wherein the dexmecamylamine or pharmaceutically acceptable salt thereof is orally administered in an amount of about 2.0 mg.
14. The method according to claim 1 , wherein the dexmecamylamine or pharmaceutically acceptable salt thereof is orally administered in an amount of about 4.0 mg.
15. The method according to claim 1 , wherein the administration is transdermal.
16. The method according to claim 1 , wherein the administration is oral.
17. The method of claim 1 , wherein the administration is sufficient to affect sweating in a patient in at least one location with an Hyperhidrosis Disease Severity Scale change of >1.
18. The method according to claim 17 , wherein the administration is sufficient to affect sweating in a patient in at least two locations with an HDSS change of ≥0.5, in each location.
