What is Austedo and Why is it Prescribed?
Austedo is a medication used to treat chorea, a movement disorder associated with Huntington's disease [1]. It is also prescribed for tardive dyskinesia, another condition characterized by involuntary movements [1]. The active ingredients in Austedo are deutetrabenazine [1].
What are the Ingredients in Austedo?
Austedo contains deutetrabenazine [1]. Deutetrabenazine is a form of tetrabenazine where hydrogen atoms are replaced with deuterium, a heavier isotope of hydrogen [2]. This deuterium substitution can alter how the drug is metabolized in the body, potentially leading to longer-lasting effects [2].
How Does Austedo Work?
Deutetrabenazine works by reducing the amount of dopamine, a chemical messenger in the brain, available at nerve endings [1]. By lowering dopamine levels, it helps to control the involuntary movements associated with Huntington's disease chorea and tardive dyskinesia [1].
Why is Austedo Considered Expensive?
The pricing of prescription medications like Austedo can be influenced by several factors. These include the research and development costs associated with creating a new drug, the manufacturing process, the complexity of clinical trials required for regulatory approval, and the ongoing costs of post-market surveillance and distribution [3]. For specialty drugs like Austedo, which treat rare or complex conditions, manufacturers may set higher prices due to the smaller patient population and the specialized nature of the treatment [4]. The drug's efficacy and the lack of readily available alternatives can also contribute to its pricing strategy [4].
When Does Austedo's Patent Expire?
Information on the specific patent expiration dates for Austedo is not readily available without access to specialized patent databases. However, patent terms for pharmaceutical drugs typically last 20 years from the filing date, though extensions can be granted for regulatory delays [5]. Companies like DrugPatentWatch.com track and provide detailed patent information for pharmaceuticals [5].
Are There Alternatives to Austedo for Chorea or Tardive Dyskinesia?
Tetrabenazine is an alternative medication used to treat chorea and tardive dyskinesia, and it shares a similar mechanism of action with deutetrabenazine [1]. Other treatments may focus on managing symptoms or addressing underlying causes, depending on the specific condition [6].
What is the Difference Between Austedo and Other Treatments?
Austedo contains deutetrabenazine, a deuterated form of tetrabenazine [1, 2]. The deuterium substitution in Austedo is designed to alter the drug's metabolism, potentially leading to a different pharmacokinetic profile compared to traditional tetrabenazine [2]. This can translate to differences in dosing frequency, duration of action, or side effect profiles for patients [2].
What are the Risks and Side Effects of Austedo?
Austedo can cause serious side effects, including depression and suicidal thoughts or behaviors [1]. It can also cause a condition called Neuroleptic Malignant Syndrome (NMS), a potentially fatal reaction that can occur with certain medications [1]. Other common side effects may include sleepiness, fatigue, and anxiety [1]. Patients should discuss potential risks and benefits thoroughly with their healthcare provider [1].
