Much of their 'on' time is not functional. Many of these people get very thin because they can't eat enough to replace the calories they burn. It's quite a wonder to those patients and their families. Mirtazapine was approved in 1996 by the U.S. Food and Drug Administration as an anti-depressive drug. Since it is FDA approved, physicians can also prescribe it for patients who have movement disorder.
Side effects reported by some patients include weight gain, dry mouth, and drowsiness.
Further research on mirtazapine and its relation to improving movement disorders should be pursued. I hope and believe that neurologists throughout the country will offer their patients an opportunity to try this drug. It can improve the quality of life of tens of thousands of patients. Other researchers said the results appear promising enough to merit larger studies before it can be widely recommended. I expect other clinicians will have the save reaction.
