Medications (e.g., epinephrine, amiodarone)

Epinephrine and amiodarone are medications used in emergencies to treat serious heart problems. Epinephrine, also known as adrenaline, helps restore blood flow during severe allergic reactions or cardiac arrests by narrowing blood vessels and increasing heart rate. Amiodarone is used to correct abnormal heart rhythms, especially life-threatening irregularities, by stabilizing electrical signals in the heart muscle. Both drugs are potent and typically administered by healthcare professionals during emergencies to support and regulate the heart’s function until normal rhythm is restored.
