What is a common route for administering Diltiazem?

Diltiazem is commonly administered via the intravenous (IV) route, especially in acute settings where rapid therapeutic effects are desired, such as in cases of acute atrial fibrillation or severe hypertension. The IV route allows for immediate bioavailability, enabling quick titration of the dose according to the patient's needs. Intravenous administration is particularly useful in hospital environments where careful monitoring can be conducted.

While diltiazem can also be given orally as a long-term treatment option for hypertension or angina, the question describes a common administration route in acute care situations, where IV administration is the preferred method for achieving prompt results. Other routes like intramuscular (IM) or subcutaneous are not typically utilized for diltiazem, as they would result in a slower onset of action.
