Propranolol and Tonocard
Determining the interaction of Propranolol and Tonocard and the possibility of their joint administration.
In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.
Consumer:Using propranolol together with tocainide can affect the rhythm of your heart. Contact your doctor if your condition worsens or if you experience heart palpitations, irregular heartbeat or any alteration in heart function. You may need a dose adjustment or special tests if your use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:MONITOR: The concomitant use of tocainide and beta-blockers may have additive effects on cardiac index, left ventricular function, and pulmonary wedge pressure. While significant interactions have not been reported in studies, cases of asystole have been reported in patients with preexisting electrophysiologic abnormalities after tocainide and metoprolol were coadministered. The mechanism is not known, but may be related to an additive effect on the sinus node or conduction system, especially in patients with sick sinus syndrome. Cases of confusion and paranoia have also been reported after coadministration of tocainide and propranolol.
MANAGEMENT: The concomitant use of tocainide and beta blockers should probably be avoided in patients with atrioventricular conduction abnormalities or sick sinus syndrome. This combination should be used cautiously in other patients, with careful dose titration and close clinical and electrocardiographic monitoring for efficacy and safety.
