Propafenone is in the class of drugs known as anti-arrhythmic. This blocks the activity of certain electrical signals in the heart that cause an irregular heartbeat. Treating an irregular heartbeat can lessen the risk of blood clots. This effect can decrease your risk of heart attack or stroke. Propafenone is supplied as tablets for oral use. Each table is available in the dosage forms of 150 mg and 225 mg. The Food and Drug Administration (FDA) has already approved this prescription.
Howdoes Propafenone work?
Propafenone lessens thesensitivity of the heart muscle cells to electrical impulses. This slows andregulates the electrical conduction in the heart muscle. In which it helps torestore disturbances in the heart rhythm. This also blocks beta receptors inthe heart that causes a decrease in heart rate and helps in the control ofarrhythmias.
The pumping action of the heart is controlled byelectrical signals that pass through the heart muscle. The electrical signalcauses the two pairs of heart chambers to contract in a regular manner thatproduces the heartbeat. If the electrical activity in the heart is disturbedfor any reason, irregular heartbeats of various types can result. These canseriously undermine the pumping action of the heart and result in inefficientblood circulation around the body.
