    Study Notes

    Flecainide

    • Flecainide is available as a generic oral medication
    • Treats ventricular arrhythmia and life-threatening supraventricular dysrhythmias
    • May require dose reduction in patients with hepatic disease
    • Dose reduction may be necessary for patients with a reduced creatinine clearance

    Flecainide

    • Generic: Flecainide
    • Route of administration: PO (Oral)
    • Indications:
      • Ventricular arrhythmia, Life-threatening
      • Supraventricular dysrhythmias
    • Drug interactions:
      • Hepatic: May require dose reduction in patients with hepatic disease
      • Renal: Dose reduction required in patients with reduced creatinine clearance (CrCl)

    Class 1C Antiarrhythmic Drugs

    • Block sodium channels in the heart, slowing electrical impulse conduction
    • Exhibit selectivity for cells with a high conductance rate
    • Prolong the effective refractory period
    • Have beta-adrenergic blocking activity
    • Both drugs are well absorbed orally
    • Propafenone has low bioavailability due to first-pass metabolism
    • Flecainide has a longer plasma half-life (14-20 hours) compared to propafenone (2-10 hours)
    • Propafenone is a racemic mixture with both enantiomers exhibiting similar antiarrhythmic activity
    • Both drugs undergo extensive metabolism, resulting in decreased activity

    Class IC Antiarrhythmic Drugs

    • Class IC antiarrhythmic drugs block sodium channels in the heart, slowing the conduction of electrical impulses.
    • These drugs have a higher affinity for cells with a rapid rate of conduction.
    • Class IC antiarrhythmics prolong the effective refractory period of the heart.
    • They can also exhibit beta-adrenergic blocking activity.
    • Both flecainide and propafenone are well absorbed orally.
    • Propafenone has a lower bioavailability due to extensive first-pass metabolism.
    • Flecainide has a significantly longer plasma half-life than propafenone (14-20 hours vs. 2-10 hours).
    • Propafenone is a racemic mixture, meaning it contains equal amounts of two enantiomers, both of which have similar antiarrhythmic activity.
    • Extensive metabolism of both drugs decreases their activity.
