epinephrine和Adrenaline有什么区别 虽然翻译都是肾上腺素

没有区别，指的是同一个东西。有时候会区别生理用还是生化用。

epinephrine
【生化】肾上腺素 分子生物学词汇

Epinephrine, also known as adrenaline, is a medication and hormone.As a medication, it is used to treat a number of conditions, including anaphylaxis, cardiac arrest, asthma, and superficial bleeding.

Adrenaline, also known as epinephrine, is a hormone and medication.Adrenaline is normally produced by both the adrenal glands and a small number of neurons in the medulla oblongata, where it acts as a neurotransmitter involved in regulating visceral functions (e.g., respiration).

维基百科貌似区分：A是生物合成表达，E是临床、生化、制药等领域的表达。东西是一个东西，来源、用途不一样。

但好像有时候国外也混用。其实看词源，确实没区别：

epinephrine：From Ancient Greek ἐπί ‎(epí, “upon”) + νεφρός ‎(nephrós, “kidney”) + English -ine.

adrenaline：From adrenal +‎ -ine. It is a New Latin calque of Ancient Greek ἐπί ‎(epí, “upon”) + νεφρός ‎(nephrós, “kidney”) + -ine, coined and trademarked by Parke-Davis, subsidiary of pharmaceutical company Pfizer. Originally spelled without the final e.

看词源又好像adrenaline是药用商品名，在epinephrine后出现，有点晕了。

所以就别区别了。
