Filed under: Eye Medication

Displayed: Epinephrine

Epinephrine (also referred to as adrenaline;) belongs to a group of drugs called (amongst others) cardiac resuscitation and is a neurotransmitter that is produced in the center of the adrenal glands. The drug is given in an emergency to stimulate heart activity and stroke volume, dilates the pupils, and constricts arterioles in the skin and gastrointestinal tract while dilating arterioles in skeletal muscles, and raise low blood pressure. The drug is injected to counteract cardiac arrest, or to relieve severe allergic reactions to drugs, food or insect stings. It is provided as a pre-filled syringe for immediate self-injection at the start of an attack for those patients who are at risk of anaphylaxis. (anaphylaxis is a severe allergic reaction that involves the entire body).

The drug can also be used as eye drops to lower the pressure within the eye. This makes it useful in glaucoma and eye surgery. Epinephrine constricts blood vessels and is used to control bleeding and controls the effect of local anaesthetics.

People with a history of anaphylaxis should carry an auto-injectable epinephrine with them at all times. As always go to the emergency room after you use it for a follow-up from the physician.
