About Ipsen`s botulinum toxin

Ipsen`s botulinum toxin (Dysport® / Reloxin® / Azzalure®) is a neuromuscular blocking toxin which acts to block acetylcholine release, hence reducing muscular spasm and was initially developed for the treatment of motor disorders and various forms of muscular spasticity, including cervical dystonia (spasmodic torticollis), spasticity of the lower limbs in children with cerebral palsy, blepharospasm (involuntary eye closure) and hemifacial spasm. It was later developed for the treatment of a wide variety of neuromuscular disorders and aesthetic medicine. Dysport® was originally launched in the United Kingdom in 1991 and has marketing authorisations in 73 countries. As of April 2008, Ipsen`s botulinum toxin type A, developed in the field of aesthetic medicine in the U.S., Canada and Japan under the trademark Reloxin®, is approved for aesthetic
indications in 23 countries: Argentina, Australia, Belarus, Brazil, Columbia, Ecuador, Egypt, El Salvador, Germany, Honduras, Israel, Kazakhstan, Mexico, Moldova, New Zealand, Philippines, Slovak Republic, South Korea, Ukraine, Uruguay, Venezuela, Vietnam, and Russia (in Russia, it is the first botulinum toxin type A approved in this field). Ipsen is also pursuing regulatory approval for medical indications for the product in certain additional key international markets.
