What is Austedo?

Austedo, along with Austedo XR (deutetrabenazine), is utilized to manage chorea (sudden involuntary movements) that are caused by Huntington's Disease (a genetic condition that causes the loss of nerve cells within the brain). Deutetrabenazine is not an effective treatment for Huntington's disease and is not a treatment for other symptoms of the condition.

Austedo is also utilized in adults to treat the symptoms that are a result of tardive dyskinesia (TD), which is an illness of the nervous system. Tardive dyskinesia is characterized by repetitive and uncontrolled muscle movements, mostly in the facial area (chewing lips, smacking the lip, or frowning) and tongue movements, blinking, or eye movements.

Austedo is part of a class of medicines known as vesicular monoamine transporter 2 (VMAT2) inhibitors. It affects the function of some chemical substances found in the brain, which influence muscles and nerves.Austedo can be taken two times a day. Austedo is taken twice daily, and Austedo XR (an extended-release tablet) is taken daily.

Motor function, or movement of the body, is controlled by brain neurons (neurons), which communicate with one another by transmitting chemical messages (neurotransmitters) between nerve cells. the next nerve cell.When there are movement disorders, such as tardive dyskinesia and Huntington's disease, there may be issues in this system. By cutting down on the amount of chemical messengers between nerve cells, you can stop the non-controlled motions.A protein called VMAT2 determines the amount of chemical messenger stored in nerve cells and how much of it is released. The VMAT2 inhibitors inhibit VMAT2 so that there are fewer neurotransmitters in the brain, which reduces undesirable body movements.
