Diagram showing how epinephrine binding to a beta-adrenergic receptor on a cell membrane activates a G-protein, which then stimulates adenylyl cyclase to convert ATP into cyclic AMP (cAMP), leading to physiological effects such as increased heart rate, blood vessel dilation, and glycogen breakdown.

Two EpiPen auto-injectors with yellow labels and blue caps are shown in front of a yellow EpiPen 2-Pak box, used for emergency allergic reaction treatment.
