Epinephrine (Adrenalin)

Photograph of Epinephrine (Adrenalin) under the microscope.

Epinephrine acts by increasing the levels of cyclic AMP leading to bronchodilation and stimulation of the heart and central nervous system. The drug is often administered through oral inhalation to prevent wheezing and difficulty in breathing. Epinephrine is more potent than many of the over-the-counter drugs used for asthma and bronchitis. Side effects include chest discomfort or pain, irregular heartbeat, dizziness, and hallucinations.
