Tambocor is an antiarrhythmic medication classified as a class iii cardiac antiarrhythmic. It is used to restore and sustain normal heart rhythm in individuals with certain ventricular and supraventricular arrhythmias. Propafenone, the active compound in Tambocor, works by blocking cardiac sodium channels and inhibiting catecholamine-mediated calcium influx. This action slows the rate of depolarization in cardiac myocytes and prolongs the effective refractory period of the atria and ventricles. The result is a reduction in abnormal electrical activity that can trigger or maintain irregular heartbeats. By stabilizing the cardiac rhythm the drug helps the heart operate more effectively and reduces symptoms such as palpitations.

Tambocor is classified as a class ic antiarrhythmic medication used to maintain normal heart rhythm. It is prescribed primarily to treat certain types of irregular heartbeat such as atrial fibrillation. The drug functions by blocking cardiac sodium channels which reduces the speed of electrical conduction in the heart. This inhibition slows the rise of the action potential and prolongs the refractory period of myocardial cells. By decreasing the excitability of cardiac tissue the medication helps prevent the rapid and disorganized electrical activity that leads to arrhythmias. Pharmacodynamically Tambocor has a long duration of action due to its extensive tissue binding and slow elimination. The steady state plasma concentration is achieved after several doses as the drug accumulates in the heart tissue. Its ability to restore and sustain sinus rhythm makes it a valuable option for patients with symptomatic atrial fibrillation when rhythm control is desired.

Dizziness may occur in some patients taking Tambocor. Headache is another frequently reported side effect. Nausea and vomiting can affect gastrointestinal comfort. Tremors or shaking of the hands are sometimes observed. Blurred vision may develop during treatment. A metallic taste sensation is occasionally noted. Drowsiness or fatigue can be experienced by users. Low blood pressure may occasionally be recorded in clinical settings.

Some patients may experience dizziness or lightheadedness after taking Tambocor. Headache is another frequently reported symptom. Nausea and mild stomach discomfort can occur. Visual disturbances such as blurred vision have been noted. Some individuals report a metallic taste in the mouth. Fatigue or unusual tiredness may be observed. In rare cases a rapid or irregular heartbeat may develop.
