Antiarrhythmic drugs types and classification representatives how they act

Antiarrhythmic drugs are prescribed by a doctor and are selected for each patient individually. The specialist draws up his own treatment regimen, which may include not only the main means, but also a group of auxiliary and supporting medicines.

Since there are a lot of medications for the treatment of arrhythmias, we can name the methods of using the most common ones for intravenous administration:

  • Novocainamide – from 0,5 to 1,5 g in 20-50 minutes.
  • Disopyramide – 150 mg in 3-5 minutes.
  • Etmosine – 150 mg in 3-5 minutes.
  • Lidocaine – 100 mg in 3-5 minutes.
  • Propranolol – 5 mg in 5 minutes.
  • Amiodarone (Cordaron) – 300-400 mg in 10-15 minutes.
  • Verapamil – 5-10 mg in 1-3 minutes.
  • Adenosine phosphate – 6 mg in 1-3 seconds.
  • Sodium adenosine triphosphate – 10 mg for 1-3 seconds.
  • Nibetan – 0,125 mg / kg of body weight.
  • Magnesium sulfate – 2,5 g in 2-5 minutes.

At the moment, the main means included by most doctors in the treatment regimen of arrhythmias are beta-blockers and Amiodarone. They have proven themselves in the treatment of patients with organic heart damage.

Side effects and contraindications

Each of the existing antiarrhythmic drugs has its own contraindications and side effects, which must be taken into account by the doctor when prescribing the drug. The age of the patient and the presence of other serious pathologies, especially as risky as stroke and heart attack, are also important.

Some antiarrhythmic drugs themselves are capable of provoking heart rhythm disturbances, therefore they are either prescribed in minimal doses in a hospital where the patient is under constant monitoring, or replaced with others that do not carry such a threat.

Equally important is the duration of the medication. Here lies the risk of self-medication – without specialized medical knowledge, an arbitrarily chosen drug can not only harm, but also aggravate the course of the underlying disease.

If we summarize the most common violations, then drugs to eliminate cardiac arrhythmias can have the following side effects:

    Allergic reactions to the composition or to indiv >

When prescribing this or that medication, the doctor takes into account specific contraindications, for example, quinidine is forbidden to use for atrioventricular and intraventricular blockade, poisoning with cardiac glycosides, thrombocytopenia, arterial hypotension, heart failure and other dangerous conditions.

Beta-blockers, which have proven themselves in the treatment of arrhythmias, are not used in the presence of bronchial asthma and atrioventricular obstruction.

In order for the doctor to prescribe the perfect drug, the patient must give him the most complete and reliable information about himself and about the presence of any diseases and disorders. Then the treatment will be as effective and safe as possible.
