Indication | Used to treat irregular heartbeats (arrhythmias) and maintain a normal heart rate. | ||||||||||
Mechanism of action | Moricizine works by inhibiting the rapid inward sodium current across myocardial cell membranes. | ||||||||||
Absorption | Well absorbed, absorption is complete within 2 to 3 hours. Significant first-pass metabolism results in an absolute bioavailability of approximately 38%. Administration within 30 minutes after a meal slows the rate, but does not affect the extent of absorption, although peak plasma concentrations are reduced. | ||||||||||
Protein binding | Approximately 95%. | ||||||||||
Biotransformation | Hepatic and extensive, to at least 26 metabolites, none accounting for as much as 1% of the administered dose. Two metabolites may be pharmacologically active but are present in extremely small quantities. Moricizine induces its own metabolism (it induces hepatic cytochrome P-450 activity). | ||||||||||
Route of elimination | Less than 1% of orally administered Ethmozine(R) is excreted unchanged in the urine. Approximately 56% of the administered dose is excreted in the feces and 39% is excreted in the urine. | ||||||||||
Toxicity | Symptoms of overdose include vomiting, unconsciousness, and severe low blood pressure. | ||||||||||
