5.1. Pharmacodynamic properties

At the concentration produced after diluting the product, magnesium chloride increases conduction time and the PR and QRS intervals are lengthened. Elevated potassium levels have significant effects on electrical activity in the heart. The T waves become increased in height, the PR interval lengthens and the P wave disappears as potassium concentration increases. The Procaine hydrochloride acts as a local anaesthetic. The primary site of action for procaine is the myocardium, resulting in a decrease in electrical excitability, conduction rate and force of contraction.


5.2. Pharmacokinetic properties

Procaine hydrochloride is almost completely metabolised with only about 2% excreted unchanged in the urine. The half life is less than one minute.


5.3. Preclinical safety data

Acute toxicity data for procaine hydrochloride indicates an LD50 of 200 mg/kg following oral administration in the Rat. There are no other additional preclinical safety data that would be of significance to the prescriber.
