'''Adrenaline''' (also known as '''epinephrine''') is a [[hormone]] and [[neurotransmitter]]. It is primarily produced in the adrenal glands and certain neurons in humans and animals.{{clarify}}{{citation needed}} | '''Adrenaline''' (also known as '''epinephrine''') is a [[hormone]] and [[neurotransmitter]].

Adrenaline is used to regulate heart rate, blood vessel and air passage diameters, and metabolic shifts. Adrenaline release is a crucial component of the fight-or-flight response of the sympathetic nervous system.{{citation needed}} | Adrenaline is used to regulate heart rate, blood vessel and air passage diameters, and metabolic shifts. Adrenaline release is a crucial component of the fight-or-flight response of the sympathetic nervous system.{{citation needed}} Adrenaline release during fight-or-flight can increase the rate of processing of information in the brain which leads to a slow motion perception due to the relativity of intertwined space and time as [https://en.wikipedia.org/wiki/Spacetime spacetime]. | ||

Direct-acting [[agonists]] have direct action upon the adrenergic system where they have action upon the adrenergic receptors themselves. These include antihypertensives (to reduce blood pressure), [[sedatives]] and [[muscle relaxants]]. | Direct-acting [[agonists]] have direct action upon the adrenergic system where they have action upon the adrenergic receptors themselves.

Indirect [[agonists]] work by increasing the [[neurotransmission]] of endogenous chemicals such as adrenaline or [[noradrenaline]]. These include many [[stimulant]] drugs, such as [[amphetamine]], [[cocaine]], [[MDMA]] and [[methylphenidate]]. | Indirect [[agonists]] work by increasing the [[neurotransmission]] of endogenous chemicals such as adrenaline or [[noradrenaline]].
