What drug class does procainamide belong to?
Procainamide is a medication used to manage and treat ventricular arrhythmias, supraventricular arrhythmias, atrial flutter/fibrillation, and Wolf-Parkinson-White syndrome. It is in the antiarrhythmic Agent Class 1A class of medications.
What is procainamide for?
Procainamide is used to treat abnormal heart rhythms. It works by making your heart more resistant to abnormal activity.
What drug group does salbutamol belong to?
Albuterol (also known as salbutamol) is used to treat wheezing and shortness of breath caused by breathing problems (such as asthma, chronic obstructive pulmonary disease). Albuterol belongs to a class of drugs known as bronchodilators.
When should you not use procainamide?
Who should not take?
- high levels of potassium in the blood.
- low amount of potassium in the blood.
- decreased blood platelets.
- very low levels of granulocytes, a type of white blood cell.
- myasthenia gravis, a skeletal muscle disorder.
- heart attack within the last 30 days.
- complete heart block.
When is procainamide contraindicated?
Procainamide is contraindicated in patients with second- or third-degree AV block, unless controlled by a pacemaker, due to the risk of additive cardiac depression. In general, use procainamide cautiously in patients with certain types of cardiac disease.
What is a class 3 antiarrhythmic drug?
Class III antiarrhythmic drugs act by blocking repolarising currents and thereby prolong the effective refractory period of the myocardium. This is believed to facilitate termination of re-entry tachyarrhythmias. This class of drugs is developed for treatment of both supraventricular and ventricular arrhythmias.
Is albuterol a rescue or control?
An albuterol inhaler is a quick-relief or rescue medication used to decrease asthma symptoms. Albuterol can decrease acute symptoms associated with worsening asthma such as: Chest tightness. Chronic Cough.
What is the most common adverse effect of procainamide *?

What is a contraindication for procainamide?
Which is the best description of procainamide?
Procainamide is a class-1 antiarrhythmic agent. It blocks myocardial Na+ channels in an open state, reduces automaticity, and maximal rate of 0 phase depolarization. It prolongs action potential duration (APD) due to K+ channel block and lengthens Effective refractory period (ERP) by its moderate effect on recovery of Na+ and K+ channels.
How does procainamide affect the effective refractory period?
It prolongs action potential duration (APD) due to K+ channel block and lengthens Effective refractory period (ERP) by its moderate effect on recovery of Na+ and K+ channels. It reduces availability of Na+ channels as well as delays their activation. It increases threshold for excitation.
How is albuterol used in the treatment of asthma?
In the U.S. Pharmacologic Class: Beta-2 Adrenergic Agonist Albuterol is used to treat bronchospasm or wheezing in patients with reversible obstructive airway disease, such as asthma. Albuterol belongs to the family of medicines known as adrenergic bronchodilators.
What is the conversion rate of procainamide to normal?
IV procainamide had a 52% conversion rate of atrial fibrillation to normal sinus and a 28% conversion rate from atrial flutter to normal sinus. [1] One recent major study looked at the difference between amiodarone and procainamide in stable ventricular tachycardia.
