One very common side-effect of anti-psychotics is a condition called tardive dyskinesia. It can be permanent and can cause twitching of the eyes, lips, tongue, and extremities.
The drug is called Ingrezza, and it's awaiting an FDA decision for the tardive dyskinesia treatment.
Christoph U. Correll, MD, Professor of Psychiatry and Molecular Medicine at Hofstra Northwell School of Medicine, said in a press release:
"Until now, one of the few options for physicians, when managing TD, was to stop, change, or lower the dose of antipsychotic medication, potentially jeopardizing patients' psychiatric stability. In clinical trials, Ingrezza significantly and rapidly improved TD symptoms compared to placebo, reducing involuntary movements acutely and through 48 weeks of treatment without compromising underlying psychiatric care. These results, combined with convenient once-daily dosing, represent a tremendous breakthrough for patients suffering from TD."
