How long do the cardiovascular effects of adrenaline typically last?

Adrenaline, also known as epinephrine, is a powerful catecholamine used in various emergency medical situations, especially for conditions like cardiac arrest and severe anaphylaxis. When administered, it causes multiple cardiovascular effects, such as increased heart rate, improved cardiac contractility, and enhanced perfusion to vital organs.

The cardiovascular effects of adrenaline are typically significant but short-lived. They generally last around 5-15 minutes. This duration allows for a rapid response in emergency situations, giving paramedics and medical responders a crucial window to stabilize the patient and implement further interventions as necessary.

It's essential to monitor a patient's response to adrenaline within this timeframe, as effectiveness can diminish, requiring additional doses if necessary. Longer durations, such as 30-60 minutes or more, would not accurately reflect the pharmacokinetics of adrenaline, as the body metabolizes and eliminates it relatively quickly, thereby reducing its acute effects on the cardiovascular system.
