Abstract

Pharmaceutical compositions for transdermal administration of neurotoxins to a patient include a neurotoxin, such as a botulinum toxin, and an enhancing agent that facilitates absorption of the neurotoxin through the skin of the patient and does not eliminate the bioactivity associated with the neurotoxin. The pharmaceutical compositions are topically applied on a patient, and may be provided in a transdermal patch.

Claims

1. A pharmaceutical composition comprising:

a stabilized botulinum toxin; and

at least one enhancing agent for facilitating transdermal delivery of the botulinum toxin into a human patient by enhancing the permeability of the patient'"'"'s skin.

2. The composition of claim 1, wherein the botulinum toxin is selected from the group consisting of botulinum toxin types A, B, C.sub.1, D, E, F and G.

3. The composition of claim 1, wherein the botulinum toxin is botulinum toxin type A.

4. The composition of claim 1, wherein the botulinum toxin is a purified botulinum toxin.

5. The composition of claim 1, wherein the composition comprises between about 1 units to about 20,000 units of botulinum toxin.

6. The composition of claim 1, wherein the composition comprises an amount of botulinum toxin to achieve a therapeutic effect lasting between 1 month and 5 years.

7. The composition of claim 1, wherein the enhancing agent is an alcohol.

8. The composition of claim 7, wherein the alcohol is a polyalcohol.

9. The composition of claim 1, wherein the enhancing agent comprises a transfersome.

10. The composition of claim 1, wherein the composition comprises a plurality of enhancing agents.

11. A pharmaceutical composition in a transdermal patch, the pharmaceutical composition comprising:

a stabilized botulinum toxin that permeates through a human patient'"'"'s skin without permeating in significant amount through a blood vessel when the botulinum toxin interacts with an enhancing agent provided in the transdermal patch to cause a therapeutic effect of a disorder associated with exocytosis of a molecule from a cell.

12. The composition of claim 11, wherein the botulinum toxin is provided in a dry state in the transdermal patch before the patch is applied to the patient'"'"'s skin.

13. The composition of claim 11, wherein the botulinum toxin is botulinum toxin type A.

14. The composition of claim 11, wherein the botulinum toxin is mixed with the enhancing agent after the transdermal patch is applied to the patient'"'"'s skin.

15. The composition of claim 14, wherein the botulinum toxin mixes with an enhancing agent that is applied to the patient'"'"'s skin before the transdermal patch is applied to the patient'"'"'s skin.

16. A transdermal patch, comprising a pharmaceutical composition, which comprises:

a stabilized botulinum toxin; and

an enhancing agent that facilitates transdermal administration of the botulinum toxin in a bioactive form to a subdermal target site of a human patient without being administered to the patient'"'"'s circulatory system; and

an adhesive disposed on one side of the transdermal patch to removably secure the patch to the patient'"'"'s skin.

17. The transdermal patch of claim 16, wherein the adhesive is disposed around a depot containing the pharmaceutical composition.

18. The transdermal patch of claim 16, further comprising a plurality of needles extending from one side of the patch that is applied to the skin, wherein the needles extend from the patch to project through the stratum corneum of the skin without rupturing a blood vessel.

19. The transdermal patch of claim 18, wherein the botulinum toxin is provided in a depot in the patch so that pressure applied to the patch causes botulinum toxin to be directed through the needles and under the stratum corneum.

20. The transdermal patch of claim 16, wherein the botulinum toxin is provided in a dry state in a plurality of wells, each of the wells covered by a membrane that is dissolvable with a fluid, and wherein the enhancing agent mixes with the botulinum toxin as the membrane over a well dissolves so that the absorption of the botulinum toxin is enhanced.
