Effectiveness
How Norpace Cr Affects PatientsDisopyramide is a drug used to treat serious heart rhythm problems. It helps to make the heart beat slower and more regularly. Disopyramide will also make areas of the heart's electrical system that control the heart rate longer, but does not have a significant effect on the other electrical pathways of the heart. However, it will cause some of the pathways to take longer to send signals.
How Norpace Cr works in the bodyDisopyramide is a type of drug used to treat irregular heart beats. It works by slowing down the electrical signals that cause your heart to beat. This drug has been shown to reduce the speed of diastolic depolarization and action potential duration in animal studies, as well as reduce the difference in refractoriness between damaged and healthy parts of the heart. Disopyramide does not affect the alpha- or beta-adrenergic receptors.

10/3/2011 I'm glad this fourth medication I tried finally worked for my atrial fibrillation. I did have to be monitored in the hospital, but it was worth it to find a treatment that actually worked and didn't cause other issues like the Multaq I was on previously.

11/10/2010 This treatment helps me stay in a normal heart rhythm, unless my potassium levels drop below 4.0.

12/19/2009 I take this medication along with Coreg twice a day. I haven't had any problems as long as I stick to the name brand; however, when I tried the generic version, I experienced breakthrough irregularity.

9/25/2013 My husband felt much better before taking this medication and told the doctor he would rather stop taking it because of the severe side effects. These included insomnia, a dry mouth and throat, constipation, and general discomfort. We stopped the medication immediately and found a different drug.
