Mirapex (pramipexole) is a pharmaceutical drug prescribed to individuals with Parkinson’s disease or restless legs syndrome (RLS). The drug was approved in 1997 and is manufactured by Boehringer Ingelheim Pharmaceuticals. Mirapex works by mimicking the action of dopamine, which is a neurotransmitter that controls the brain’s reward and pleasure centers.
Parkinson’s disease causes progressive loss of dopamine production in the brain, and low dopamine levels have been linked to restless leg syndrome. Dopamine agonist drugs, like Mirapex, treat these symptoms and act in place of dopamine. Mirapex has several associated side effects, including headache, insomnia, vomiting, and stomach pain. In addition, the drug has been linked to sudden sleep attacks and compulsive behaviors.
FDA evaluating the increased risk of heart failure with Mirapex use
In 2012, the U.S. Food and Drug Administration (FDA) informed the public about a potential increased risk of heart failure with Mirapex. The agency said that, after evaluating two studies suggesting an increased onset of heart failure while taking Mirapex, an ongoing safety review will take place.
The FDA is working with the manufacturer of the drug to further clarify the link between the drug and heart failure. One of the studies revealed that newly diagnosed heart failure occurred more frequently in patients taking Mirapex than a placebo, but that the difference was not statistically significant. The second study revealed an increased risk of heart failure only in the first three months of treatment.
Heart failure is characterized by the heart failing to pump enough blood to meet the needs of the rest of the body. Symptoms of heart failure include shortness of breath, fatigue, chronic coughing, confusion, lack of appetite, and high heart rate.
