Which drug can be infused either intermittently or continuously?

Furosemide is a diuretic that can be administered either intermittently or continuously, depending on the clinical scenario and the required therapeutic effect. When used intermittently, it is often dosed in specific intervals to help manage conditions like edema or hypertension. On the other hand, for cases requiring more continuous management of fluid balance, such as in patients with acute renal failure or heart failure, furosemide can be infused continuously through an intravenous line. This flexibility in administration makes it a versatile medication in various treatment settings.

While medications like epinephrine can be given continuously in certain emergency situations, it is typically administered as an intermittent bolus for doses; therefore, it's not as commonly used for long-term continuous infusion in routine treatments. Clindamycin is generally given as an intermittent infusion and is not commonly used for continuous infusion due to its pharmacokinetics. Vancomycin, while it can be infused over a prolonged period, is usually administered intermittently to achieve peak and trough levels for effective therapeutic monitoring, primarily in infection control scenarios. Thus, furosemide stands out as the drug that can be effectively administered through both methods based on patient needs.
