Catecholamines:
Epinephrine (最早使用的adrenrgic 藥物) | Sti α βreceptor | 會受COMT代謝影響,可用來止血、緩解過敏、CPCR、拔管後stridor inhalation用 |
Isoproterenol | Sti β1、2 receptor | 使BP↑、HR↑、心律不整 有Bronchodilator作用 |
Isoetharine | Sti β2 receptor | Onset快、duration短 |
Racemic epi | L-isomer(左旋):人體大屬於此類 D-isomer(右旋) | 效果僅50% |

- CH2OH: Pirbuterol, Albuterol,n Salmeterol
- Phenol: Ritodrine
- Others: Indacaterol (amide linkage),n Formoterol (formamide)

isoetharine
含有catechol結構-->受COMT代謝
且是代謝在間位-OH上
