Summary
- Valbenazine (Ingrezza) is indicated for the treatment of adults with tardive dyskinesia and chorea associated with Huntington’s disease.
- A total of 6 systematic reviews/meta-analyses were reviewed to gather information about Ingrezza's efficacy, safety, tolerability, and acceptability in treating these conditions.
- Both valbenazine dosages (40mg/d and 80mg/d) showed superiority over placebo in terms of Abnormal Involuntary Movement Scale score reduction, Clinical Global Impression of Change-TD improvement, and response to treatment; however, the higher dosage demonstrated better results than the lower one without significant differences in acceptability or safety outcomes.
- Compared to another vesicular monoamine transporter 2 inhibitor deutetrabenazine used for tardive dyskinesia treatment, valbenazine exhibited robust efficacy at a dose of 80 mg/day both short-term and long-term while more data on long-term effects are needed for deutetrabenazine.
- Another review found that two VMAT-2 inhibitors including valbenzine effectively treated TD acutely as well as long term without increasing risk factors such as depression or suicide among patients suffering from chronic mental illnesses like schizophrenia.
- One study reported moderate-quality evidence suggesting that use of valbenzine may be effective in relieving symptoms related to tardive dyskinesia but emphasized need for further trials due its small sample size limitation.
