Study Notes
Indications and Contraindications
- Main indication for using diltiazem: AFib with RVR or Paroxysmal SVT
- Contraindication: Sick sinus syndrome without a functioning ventricular pacemaker
Effects on AV Node
- Diltiazem prolongs AV node refractory periods
- In patients without sick sinus syndrome, diltiazem prolongs AV node refractory periods
Pharmacology
- Class of diltiazem based on its mechanism of action: Calcium channel blocker
- Route of excretion: Primarily excreted in the urine and bile
- Route of excretion after metabolism: Renal elimination
Adverse Effects and Interactions
- Adverse effect commonly associated with diltiazem use: Bradycardia
- Not commonly associated with diltiazem use: Changes in serum calcium concentrations
- Additive effects when used concurrently with beta-blockers or digitalis: Increased risk of bradycardia and AV block
- Precaution associated with diltiazem use: Patients with sick sinus syndrome require a functioning ventricular pacemaker
Dosage
- Initial dose for AFib with RVR or Paroxysmal SVT: 0.25 mg/kg
- 2nd dose for AFib with RVR or Paroxysmal SVT: 0.35 mg/kg, given 15 minutes after the first dose, with permission from a physician
Pregnancy and Concentration
- Pregnancy category: C
- Concentration of diltiazem: Not specified
