4.3 Drug Indication

For the treatment of life-threatening ventricular arrhythmias.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Procainamide is an agent indicated for production of local or regional anesthesia and in the treatment of ventricular tachycardia occurring during cardiac manipulation, such as surgery or catheterization, or which may occur during acute myocardial infarction, digitalis toxicity, or other cardiac diseases. The mode of action of the antiarrhythmic effect of Procainamide appears to be similar to that of procaine and quinidine. Ventricular excitability is depressed and the stimulation threshold of the ventricle is increased during diastole. The sinoatrial node is, however, unaffected.


5.2 MeSH Pharmacological Classification

Voltage-Gated Sodium Channel Blockers

A class of drugs that inhibit the activation of VOLTAGE-GATED SODIUM CHANNELS. (See all compounds classified as Voltage-Gated Sodium Channel Blockers.)


Anti-Arrhythmia Agents

Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade. (See all compounds classified as Anti-Arrhythmia Agents.)

5.5 Absorption, Distribution and Excretion

Absorption

75 to 95%


Route of Elimination

Trace amounts may be excreted in the urine as free and conjugated p-aminobenzoic acid, 30 to 60 percent as unchanged PA, and 6 to 52 percent as the NAPA derivative.


Volume of Distribution

2 L/kg


PROCAINAMIDE IS RAPIDLY & ALMOST COMPLETELY ABSORBED FROM GI TRACT. WHEN... GIVEN ORALLY, ITS PLASMA CONCN BECOMES MAX IN ABOUT 60 MIN; AFTER IM ADMIN PEAK PLASMA CONCN ARE REACHED IN 15-60 MIN.

Goodman, L.S., and A. Gilman. (eds.) The Pharmacological Basis of Therapeutics. 5th ed. New York: Macmillan Publishing Co., Inc., 1975., p. 695


AT ORDINARY PLASMA CONCN, ONLY 15%...IS BOUND TO MACROMOLECULAR CONSTITUENTS OF PLASMA. CONCN OF DRUG IN MOST TISSUES EXCEPT BRAIN IS GREATER THAN THAT IN PLASMA. APPROX 60% OF DRUG IS EXCRETED BY KIDNEY. TWO TO 10%...IS RECOVERED IN URINE AS FREE & CONJUGATED P-AMINOBENZOIC ACID.

Goodman, L.S., and A. Gilman. (eds.) The Pharmacological Basis of Therapeutics. 5th ed. New York: Macmillan Publishing Co., Inc., 1975., p. 695


CONSIDERABLE DIFFERENCES...OBSERVED IN PROCAINAMIDE & ALSO PROCAINAMIDE ETHOBROMIDE DISPOSITION. ETHOBROMIDE IS CLEARED RAPIDLY IN BILE OF RATS & RABBITS, BUT ONLY SLOWLY IN DOGS. 64% OF ORALLY DOSED PROCAINAMIDE IS VOIDED AS UNCHANGED...IN HUMAN URINE, WHEREAS IN RHESUS MONKEY IT IS ALMOST COMPLETELY METABOLIZED.
