Q: What is Austedo?

Austedo contains the active ingredient deutetrabenazine and belongs to a class of medications known as vesicular monoamine transporter 2 (VMAT2) inhibitors . This medication functions by decreasing the amount of certain natural substances in the brain that are involved in nerve and muscle function. By modulating these chemical messengers, the drug helps to manage abnormal, uncontrollable body movements.

Q: What is Austedo used for?

Austedo is used to treat chorea associated with Huntington disease and tardive dyskinesia .

Q: How does Austedo work?

Mechanism of Action Austedo is classified as a vesicular monoamine transporter 2 (VMAT2) inhibitor. It targets a specific protein in the brain that is responsible for storing and releasing chemical messengers, particularly dopamine. Dopamine plays a key role in how the brain sends signals to control physical movements. In conditions such as Huntington's disease chorea and tardive dyskinesia, these signals can become overactive, leading to uncontrollable or jerky movements. Austedo works by: Blocking the VMAT2 protein: This prevents the protein from moving dopamine into the areas of the nerve cells where it is stored for release. Reducing dopamine levels: By limiting the amount of dopamine available at the nerve endings, the medication helps dampen the overactive signals that cause involuntary movements. While the exact way the drug improves movement disorders is not fully understood, it is believed that this reduction in dopamine activity is the primary reason for its effectiveness. The Role of Deuterium Austedo is a modified version of an older medication called tetrabenazine. It contains deuterium, a naturally occurring form of hydrogen. This structural change causes the body to break down the medication more slowly, which allows for more stable levels of the drug in the body over time.

Q: What forms and strengths does Austedo come in?

Austedo is provided in the following oral dosage forms: Tablets: An immediate-release formulation. Extended-release tablets: A formulation designed to release the medication over a longer period, marketed as Austedo XR.

Q: What is the FDA approval status of Austedo?

FDA Approval History The U.S. Food and Drug Administration (FDA) first approved Austedo in April 2017. It was the first deuterated drug product approved by the FDA. Initially indicated for the treatment of chorea associated with Huntington’s disease, its approval was expanded in August 2017 to include the treatment of tardive dyskinesia in adults. In February 2023, the FDA approved a once-daily extended-release formulation known as Austedo XR. Boxed Warning Austedo contains a boxed warning, the FDA’s most serious type of warning, regarding the risk of depression and suicidality in patients with Huntington’s disease. Clinical trials showed an increased risk of suicidal thoughts and behaviors in patients taking this class of medication for Huntington’s chorea. Healthcare providers are advised to balance the risks of depression and suicide with the clinical need for chorea treatment and to monitor patients closely for new or worsening symptoms. Regulatory Requirements Austedo is a prescription-only medication. While it does not require a specific Risk Evaluation and Mitigation Strategy (REMS) program, it must be dispensed with a Medication Guide that explains its risks and proper use. The medication is contraindicated in patients who are actively suicidal or who have untreated or inadequately treated depression. It is also contraindicated in patients with hepatic impairment and those taking certain other medications, such as monoamine oxidase inhibitors (MAOIs) or reserpine.
