Mechanism

Diltiazem is a potent vasodilator, increasing blood flow and variably decreasing the heart rate via strong depression of A-V node conduction. Its pharmacological activity is somewhat similar to verapamil.

It is a potent vasodilator of coronary and peripheral vessels, which reduces peripheral resistance and afterload.

Because of its negative inotropic effect, diltiazem causes a modest decrease in heart muscle contractility and reduces myocardium oxygen consumption. Its negative chronotropic effect results in a modest lowering of heart rate, due to slowing of the sinoatrial node. It results in reduced myocardium oxygen consumption.

Because of its negative dromotropic effect, conduction through the AV (atrioventricular) node is slowed, which increases the time needed for each beat. This results in reduced myocardium oxygen consumption.

Nontherapeutic effects and toxicities

A reflex sympathetic response, caused by the peripheral dilation of vessels and the resulting drop in blood pressure, works to counteract the negative inotropic, chronotropic and dromotropic effects of diltiazem. Undesirable effects include hypotension, bradycardia, dizziness, and flushing.

Indications

The drug is indicated for angina:

    Stable angina (exercise-induced) – diltiazem increases coronary blood flow and decreases myocardial oxygen consumption, secondary to decreased peripheral resistance, heart rate, and contractility.

    Variant angina – it is effective owing to its direct effects on coronary dilation.

    Unstable angina (preinfarction, crescendo) – diltiazem may be particularly effective if the underlying mechanism is vasospasm.

For supraventricular tachycardias, diltiazem appears to be as effective as verapamil in treating re-entrant supraventricular tachycardia.

Atrial fibrillation or atrial flutter (PSVT) is another indication. The initial bolus should be 0.25 mg/kg, intravenous (IV).

Because of its vasodilatory effects, diltiazem is useful for treating hypertension. Calcium channel blockers are well tolerated, and especially effective in treating low-renin hypertension.

Dosage

  • The dose of diltiazem in supraventricular tachycardias is 0.25 mg/kg, slow IV push. Most commonly, a 20 mg IV dose is given to the average-sized patient.
