Epinephrine, also known as adrenaline, is a hormone and neurotransmitter that plays a crucial role in the “fight or flight” response of the sympathetic nervous system (SNS). The adrenal glands, situated on top of each kidney, produce it and release it into the bloodstream in response to stress or danger.

Uses

1. Anaphylaxis Treatment:

Epinephrine is a frontline medication for the emergency treatment of severe allergic reactions (anaphylaxis).

2. Cardiac Arrest:

It is used in cardiac arrest to stimulate the heart and restore circulation.

3. Asthma and Respiratory Distress:

Epinephrine can relieve bronchoconstriction and improve breathing in acute asthma attacks or severe respiratory distress.

4. Bradycardia:

In cases of severe bradycardia (slow heart rate), healthcare providers may use epinephrine to increase heart rate.

5. Local Hemostasis:

Medical practitioners add epinephrine to local anesthetics in certain medical procedures to prolong their effect and reduce bleeding.

Stability and Storage Conditions

Stability: Epinephrine solutions are generally stable, but light, temperature, and pH can affect stability.

Storage: Store it typically in cool, dark conditions, and specific formulations may require refrigeration.

Different Types of Formulations

1. Auto-Injectors:

Epinephrine is commonly available in auto-injector devices, such as EpiPen, for easy and quick administration during emergencies.

2. Prefilled Syringes:

Some formulations come in prefilled syringes for administration by healthcare professionals.

3. Intravenous Solutions:

Hospitals may administer epinephrine intravenously for more controlled and continuous delivery.
