Clinical experience and treatment considerations with vesicular monoamine transport 2 inhibitors.

Abstract

Vesicular monoamine transporter 2 inhibitors (VMAT2i) are currently Food and Drug Administration-approved for the treatment of Huntington disease chorea and tardive dyskinesia. Additionally, they are often used for other hyperkinetic movement disorders in clinical practice. Due to a lack of head-to-head clinical trials, management of VMAT2i in the clinical setting may be unclear and rely on the clinical experience of the practitioner. Due to the limited distribution model, which typically requires VMAT2i to be dispensed by specialty pharmacies, access and initiation of treatment may present as barriers. Patient cases allow for the exploration of switching between VMAT2i, alternative routes of administration, utilization in pediatric and off-label conditions, and how to successfully initiate and monitor a patient on VMAT2i therapy.
