What is the duration of action for Labetalol?

• A. 4 hours
• B. 6 hours
• C. 8 hours
• D. 12 hours

Answer: (C)

The duration of action for Labetalol is typically around 8 hours. This beta-blocker and alpha-1 blocker is primarily used to manage hypertension and can be administered intravenously or orally. When given intravenously, its effects are seen relatively quickly, but the sustained duration of 8 hours makes it effective for maintaining stable blood pressure levels over a significant portion of the day. This characteristic allows healthcare providers to effectively control blood pressure with fewer doses throughout the day, improving patient compliance and overall treatment efficacy. Understanding this pharmacokinetic profile is crucial when considering Labetalol in therapeutic scenarios, particularly in acute care settings or for managing chronic hypertension.
