What Conditions Does Rystiggo Treat?
Rystiggo is approved for the treatment of generalized myasthenia gravis (gMG) in adult patients who are anti-acetylcholine receptor (AchR) antibody positive [1]. Myasthenia gravis is a chronic autoimmune disease that causes weakness in the skeletal muscles, which are responsible for breathing and other vital functions [3].
How Does Rystiggo Work?
Rystiggo works by blocking the acetylcholinesterase enzyme. This enzyme breaks down acetylcholine, a neurotransmitter that helps transmit nerve signals to muscles. By inhibiting acetylcholinesterase, rizagristig increases the amount of acetylcholine available at the neuromuscular junction, thereby improving muscle strength [1].
What Are the Side Effects of Rystiggo?
Common side effects reported for Rystiggo include [1]:
* Gastrointestinal issues, such as nausea, diarrhea, and abdominal pain.
* Musculoskeletal pain.
* Headache.
* Upper respiratory tract infections.
Patients considering or taking Rystiggo should discuss potential side effects and management strategies with their healthcare provider.
Who Makes Rystiggo?
Rystiggo is manufactured by UCB [1].
How Does Rystiggo Compare to Other Myasthenia Gravis Treatments?
Rystiggo is a treatment option for adults with a specific subtype of generalized myasthenia gravis (gMG). Other treatments for gMG include immunosuppressants, plasma exchange, and intravenous immunoglobulin (IVIg) therapy, which aim to reduce the autoimmune attack on the neuromuscular junction [3]. Rystiggo's mechanism of action, focusing on increasing acetylcholine availability, offers a different therapeutic approach [1]. The choice of treatment depends on individual patient factors, disease severity, and physician recommendations.
