Botulinum Toxin A Creates Muscle Weakness and Atrophy Following Long Term Use, Study Suggests
Date: 8.12.2010
A new study by researchers at the Faculty of Kinesiology, University of Calgary, is raising questions about the therapeutic use of botulinum toxin A.
The study found that animals injected with Clostridium Botulinum type A neurotoxin complex (BOTOX, Allergan, Inc., Toronto, Ontario, Canada) experienced muscle weakness in muscles throughout the body, even though they were far removed from the injection site. The study also found that repeated injection induced muscle atrophy and loss of contractile tissue in the limb that was not injected with the Toxin.
