In the EASE-PD Adjunct study, once daily use of REQUIP XL 24-Hour was generally well tolerated. The withdrawal rate due to adverse events was low and similar between the two groups (REQUIP XL 24-Hour 5 percent versus placebo 5 percent). The most common adverse events reported in patients taking REQUIP XL 24-Hour (n=202) versus placebo (n=191) were dyskinesia (13 percent versus 3 percent), nausea (11 percent versus 4 percent), dizziness (8 percent versus 3 percent), somnolence (7 percent versus 4 percent), hallucinations (6 percent versus 1 percent), and orthostatic hypotension (5 percent versus 2 percent).
A Progressively Disabling Disease
Parkinson's disease is a chronic, progressive and debilitating neurological condition that impairs the body's ability to move and balance. Researchers have determined that Parkinson's disease involves pathways in the brain responsible for motor control that are functioning improperly. Patients with Parkinson's disease experience a reduction in dopamine, a key chemical in the brain that communicates messages about movement, resulting in the symptoms of Parkinson's disease. These symptoms may include bradykinesia (slower-than- normal voluntary movements), rigidity (stiffness), tremor (involuntary shaking) and postural instability (trouble with balance).
More than one million people in the United States have
Parkinson's disease, and it is estimated that nearly 60,000 new
cases are diagnosed in the U.S. each year. Most people develop
Parkinson's disease between the ages of 40 and
