What drug class is tocainide?

What drug class is tocainide?

Tocainide belongs to the group of medicines known as antiarrhythmics. It is used to correct irregular heartbeats to a normal rhythm.

Is Tocainide active after oral administration?

Tocainide is an orally active lidocaine analog indicated for the suppression of ventricular arrhythmias. It is electrophysiologically similar to lidocaine and produces minimal hemodynamic and electrocardiographic changes.

Can mexiletine cause bradycardia?

Mexiletine has little effect on cardiac contractility. Syncope, hypotension, hypertension, bradycardia, conduction disturbances, atrial arrhythmias, edema, and congestive heart failure have occurred. Rare cases of torsades de pointes have been associated with mexiletine.

How does IB antiarrhythmics work?

Class IB antiarrhythmics suppress automaticity of conduction tissue by increasing the electrical stimulation threshold of the ventricle and His-Purkinje system and inhibiting spontaneous depolarization of the ventricles during diastole through a direct action on the tissues.

What are the side effects of Tocainide?

Common side effects of Tonocard (tocainide HCl) include:

• dizziness.
• spinning sensation (vertigo)
• tiredness.
• upset stomach.
• nausea.
• vomiting.
• decreased appetite.
• diarrhea.

What class is propranolol?

Propranolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.

What type of drug is prednisone?

Prednisone is in a class of medications called corticosteroids. It works to treat patients with low levels of corticosteroids by replacing steroids that are normally produced naturally by the body. It works to treat other conditions by reducing swelling and redness and by changing the way the immune system works.

Why was mexiletine discontinued?

Mexiletine therapy was associated with frequent, though readily reversible, adverse reactions. However, mexiletine treatment had to be discontinued permanently in 8 of 92 patients (9%) because of intolerable side effects.

• nausea (feeling sick)
• shortness of breath (if this gets so bad that you feel unsafe, seek medical attention immediately).

How do you learn antiarrhythmic drugs?

The mnemonic to remember the different classes of antiarrhythmic medications is “Some Block Potassium Channels”. “Some” = Sodium channel blockers = Class I antiarrhythmics. “Block” = Beta blockers = Class II antiarrhythmics. “Potassium” = Potassium channel blockers = Class III antiarrhythmics.

Does Tocainide cause fatigue?

TONOCARD (tocainide hcl) commonly produces minor, transient, nervous system and gastrointestinal adverse reactions, but is otherwise generally well tolerated….QUESTION.

What is the mechanism of action of tocainide?

Tocainide is a Class I antiarrhythmic compound with electrophysiologic properties in man similar to those of lidocaine, but dissimilar from quinidine, procainamide, and disopyramide. Tocainide acts on sodium channels on the neuronal cell membrane, limiting the spread of seizure activity and reducing seizure propagation.

Is there a class IB drug called tocainide?

Tocainide (Tonocard) is a class Ib antiarrhythmic agent. It is no longer sold in the United States. Tocainide is a lidocaine analog, that does not have significant 1st pass metabolism.

How much Tocainide is excreted in urine?

In the blood tocainide is 10-20% protein bound. The Volume of distribution is 2.5-3.5 L/kg. 30-50% is excreted unchanged in the urine. The more active R-isomer is cleared faster in anephric patients or those with severe renal dysfunction.

What happens when Tocainide is combined with Abatacept?

The metabolism of Tocainide can be increased when combined with Abatacept. The serum concentration of Tocainide can be increased when it is combined with Abiraterone. Tocainide may increase the arrhythmogenic activities of Acebutolol. The metabolism of Acenocoumarol can be decreased when combined with Tocainide.
