What’s in Dysport
Dysport 500 unit
Dysport has been approved by US FDA in 2009 for carrying out the treatment of cervical dystonia or blepharospasm in the adults, apart from cosmetic treatment. These have been running successfully over the years. Each sterile vial contains 500 units of lyophilized abobotulinumtoxinA. Nonmedicinal ingredients: human serum albumin and lactose.
Botulinum toxin belongs to the class of medications called neuromuscular paralytic agents. It blocks the nerves that are responsible for muscle activity. For cosmetic purposes, it can be used to smooth out facial lines and wrinkles, such as those that form between the eyebrows, on the forehead, and around the eyes (crow’s feet). It gives skin a smoother appearance by relaxing the muscles in the area where it was injected. It may also be used to treat cervical dystonia, also known as spasmodic torticollis, a condition in which the muscles of the neck stay in a state of contraction, and to treat focal spasticity such as arm spasms after a stroke.
