esmolol

Esmolol is a medication used primarily to manage fast heart rates and high blood pressure, particularly in emergency situations. It belongs to a class of drugs called beta-blockers, which work by blocking the effects of adrenaline on the heart, leading to a slower heart rate and reduced strength of heart contractions. This helps to lower blood pressure and reduce the heart’s workload. Esmolol is unique because it acts quickly and has a short duration, making it useful in controlled hospital settings for immediate treatment of certain cardiovascular conditions.
