Valbenazine
Valbenazine
Valbenazine (pronounced val-ben-a-zeen) is a medication used primarily for the treatment of tardive dyskinesia, a neurological disorder. It is marketed under the brand name Ingrezza.
Etymology
The name "Valbenazine" is derived from the chemical structure of the drug, which is a valine ester of (+)-alpha-dihydrotetrabenazine. The "val" refers to valine, an amino acid, and "benazine" refers to tetrabenazine, a related medication.
Usage
Valbenazine is used to treat tardive dyskinesia, a condition characterized by involuntary movements, most often affecting the face. The drug works by reducing the amount of dopamine released in the brain, which helps to control these movements.
Side Effects
Common side effects of valbenazine include fatigue, dry mouth, and constipation. In rare cases, it can cause akathisia, a condition characterized by a feeling of inner restlessness and a compelling need to be in constant motion.
