Merz is dedicated to the development of botulinum neurotoxin for therapeutic use; we are constantly working to advance new treatment standards and improve the quality of research, education and patient care within the movement disorders space.

For patients with movement disorders, botulinum neurotoxin is often the treatment of choice.

What is Botulinum Neurotoxin?

Botulinum neurotoxin is a very complex substance produced by bacteria. Botulinum neurotoxin attaches itself exclusively to nerve cells that activate the muscular system or specific glands – effectively and accurately blocking an overactive muscle or gland. The effect is reversible after a certain period of time (depending on dosage and injection location), so that repetition of the injection is typically necessary.

Every Patient is Unique

Every patient is unique and has individual therapeutic needs. Merz strives to provide more good days to every patient by investigating novel and flexible neurotoxin treatment options. For patients with movement disorders associated with muscle spasms, such as blepharospasm and cervical dystonia, or with spasticity in the upper limbs after a stroke, individualized injection therapy with botulinum neurotoxin can mean a significant increase in quality of life.

What is Dystonia?

Dystonia is a neurological movement disorder characterized by involuntary muscle spasms and abnormal postures. Recent epidemiological studies indicate that there are more than 500 000 people across Europe with some form of the disorder. Botulinum neurotoxin is the primary treatment for two common types of dystonia, spasmodic torticollis (also known as cervical dystonia) and blepharospasm.

What is Spasticity?

Spasticity occurs when part of the nervous system that controls muscle activity becomes damaged. The damage can arise from injury or a medical event such as a stroke. Overall, spasticity affects about 500,000 people in the United States and more than 12 million people throughout the world.

As part of the rehabilitation process following a stroke, physiotherapy, injections of botulinum neurotoxin into spastic muscles, occupational therapy, speech therapy, medication, psychological support, and professionals in community teams may be recommended to help a person cope with the symptoms of spasticity.
