Transdermal botulinum toxin administration for the treatment of spastic muscle pain

摘要

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.
