When is procainamide given

Immediate-acting procainamide usually is taken every 3 or 4 hours. The long-acting product is usually taken every 6 or 12 hours.

Can you take procainamide orally?

PRONESTYL (procainamide hydrochloride) is supplied for oral administration as capsules and tablets in potencies of 250, 375, and 500 mg.

Is procainamide for short term use?

Procainamide is also used for short-term treatment of ventricular tachycardia and a variety of supraventricular tachycardias, primarily atrial flutter and atrial fibrillation.

How do you make a procainamide infusion?

Intravenous Administration Each 100 mg of procainamide must be diluted in 10 ml of sterile water for injection or D5W injection. Inject by slow IV push at a rate not to exceed 50 mg/minute. Intravenous infusion: NOTE: According to the manufacturer, procainamide injection is compatible in D5W.

How is procainamide metabolized?

Procainamide is eliminated by hepatic metabolism and renal excretion. It is metabolized to N-acetyl procainamide (NAPA), by conjugation by N-acetyl transferase.

Can procainamide cause dry eyes?

Tell your doctor immediately if any of these rare but very serious side effects occur: seizures, mental/mood changes (e.g., depression, confusion, unusual thoughts/behavior, hallucinations), muscle pain/weakness, dry mouth/eyes. A very serious allergic reaction to this drug is rare.

How do you monitor procainamide?

How should I monitor my patient? A. Initiate procainamide while your patient is hospitalized and monitor cardiac rate and rhythm, including QTc interval; BP; and monitor for hypersensitivity reactions. Also monitor his complete blood cell count, ANA titer, and kidney and liver function for blood abnormalities.

How long does procainamide stay in your system?

Pharmacokinetics. Procainamide is rapidly eliminated (half-life, 3 to 4 hours) by hepatic metabolism and renal excretion of unchanged drug.

What is procainamide given for?

Procainamide is used to help keep the heart beating normally in people with certain heart rhythm disorders of the ventricles (the lower chambers of the heart that allow blood to flow out of the heart).

Why is procainamide used in WPW?

The use of intravenous procainamide is a reliable and rapid method of identifying patients with the Wolff-Parkinson-White syndrome who may be at risk for circulatory insufficiency or sudden death in case of atrial fibrillation.

What is IV procainamide?

Descriptions. Procainamide injection is used to treat irregular heartbeats and to slow an overactive heart. When the heart has a normal heartbeat (rhythm), it will work more efficiently. Procainamide works by slowing the nerve impulses in the heart and reducing the sensitivity of heart tissues.

What are the side effects of procainamide?

sudden fever, chills, sore throat, mouth sores, weakness;
joint pain, muscle pain or weakness;
wheezing, chest pain;
easy bruising, pale or yellowed skin, dark colored urine;
depression, dizziness, hallucinations;

How is procainamide eliminated?

Approximately 50% of administered procainamide is eliminated as unchanged drug via the kidneys. N-Acetylprocainamide is the main metabolite and is the main metabolite and is pharmacologically active, with a recovery in urine of about 15% (range 7 to 34% in healthy subjects).

What causes Torsades de Pointes?

Common causes for torsades de pointes include drug-induced QT prolongation and less often diarrhea, low serum magnesium, and low serum potassium or congenital long QT syndrome. It can be seen in malnourished individuals and chronic alcoholics, due to a deficiency in potassium and/or magnesium.

What is the half life of procainamide?

The therapeutic concentration of procainamide is 4-8 µg/mL. The half-life is 3-5 hours. The toxic concentration is 16 µg/mL or greater, although symptoms may develop at 8-10 µg/mL. The therapeutic concentration of NAPA is also 4-8 µg/mL, and its half-life is approximately 7 hours.

Is 500mg of Depakote a lot?

Depakote ER is indicated for prophylaxis of migraine headaches in adults. The recommended starting dose is 500 mg once daily for 1 week, thereafter increasing to 1000 mg once daily.

How is procainamide toxicity treated?

In overdose, charcoal can be considered after securing the airway but the mainstay treatment for toxicity is treatment of underlying rhythms using sodium bicarbonate, magnesium, and overdrive pacing. In chronic toxicity, procainamide has been linked to a drug-induced systemic lupus erythematosus syndrome.

Is amlodipine an antiarrhythmic?

Dihydropyridines, like amlodipine, nicardipine, and nifedipine, are highly selective for calcium channels on the vascular smooth muscle tissue; so they’re primarily used to treat hypertension. On the other hand, non-dihydropyridines are the class IV antiarrhythmics and they include verapamil and diltiazem.

When do you stop procainamide infusion?

Please note, the use of procainamide should be stopped if any of the following occurs, arrhythmia suppression, onset of hypotension, QRS complex widens by greater than 50% of the pretreatment width or the maximum dose of 17 mg per kg is reached.

Can you use procainamide long term?

Introduction. Procainamide is an oral antiarrhythmic agent that has been in use for more than 60 years. Long term procainamide therapy is known to induce hypersensitivity reactions, autoantibody formation and a lupus-like syndrome but is a rare cause of clinically apparent acute liver injury.

Can I stop taking amlodipine after 3 days?

Do not stop taking amlodipine suddenly. Although no “rebound” effect has been reported, it is better to slowly decrease the dosage over a period of time. Your doctor may advise you to take sublingual nitroglycerin for any break-through angina pain.

How does procainamide cause lupus?

For example, whereas some drugs can cause DILE, others may cause a flare of preexisting SLE. Drugs such as procainamide, chlorpromazine, and quinidine cause the production of antinuclear antibodies against the histone dimer H2A-H2B.

What is the side effects of verapamil?

Blue lips and fingernails.
chest pain.
coughing that sometimes produces a pink frothy sputum.
difficult, fast, noisy breathing, sometimes with wheezing.
dizziness, faintness, or lightheadedness when getting up from a lying or sitting position suddenly.
lightheadedness, dizziness, or fainting.
shortness of breath.

What are the side effects of lidocaine?

Bluish-colored lips, fingernails, or palms blurred or double vision.
chest pain or discomfort.
cold, clammy, pale skin.
continuing ringing or buzzing or other unexplained noise in the ears.
difficulty breathing.
difficulty swallowing.
dizziness or lightheadedness.

Why is gabapentin bad?

Some of the severe side effects include trouble breathing and allergic reactions. People who start to use gabapentin should pay attention to shifts in mood or emotions. For example, a person who experiences increased anxiety, anger, or panic attacks should contact a doctor right away.

What kind of drug is adenosine?

Adenosine is a prescription drug used for conversion to sinus rhythm of paroxysmal supraventricular tachycardia (PVST), including that associated with accessory bypass tracts (Wolff-Parkinson-White Syndrome).

How does procainamide treat WPW?

Procainamide, a class 1A antiarrhythmic, increases effective refractory period and reduces impulse conduction velocity and excitability in the atria, His-Purkinje fibers, ventricular muscle, and the AP of the heart.

Why dont you give adenosine to WPW?

The concern with using adenosine in patients with WPW is that if the AV node is blocked than impulses from the atria will be able to reach the ventricles at a very rapid rate, since they are not slowed down through the accessory pathway as they are at the AV node.

Can you give adenosine to WPW?

Adenosine has no effects on accessory pathways, such as those seen in the Wolf-Parkinson White Syndrome (WPW). Mild side effects of adenosine are common.

Is procainamide the same as lidocaine?

A comparison of the QRS width and QT interval before and at the end of the injection revealed significant lengthening of these values after procainamide but no change after lidocaine. In conclusion, procainamide is superior to lidocaine in terminating spontaneously occurring monomorphic VT.
