Adrenaline hmoovyog dawb los yog tawm-dawb crystalline hmoov; odorless, iab hauv saj; chemically tsis ruaj khov, nyob rau hauv kev sib cuag nrog huab cua los yog hnub ci, nyob rau hauv lub xub ntiag ntawm oxides, alkalis, lub teeb thiab tshav kub, nws yog yooj yim oxidized rau liab, thiab ces ua liab. Brown thiab poob. Cov khoom no yog me ntsis soluble nyob rau hauv dej, insoluble nyob rau hauv ethanol, chloroform, ether, fatty roj los yog volatile roj; yooj yim soluble nyob rau hauv mineral acid los yog sodium hydroxide tov, insoluble nyob rau hauv ammonia tov los yog sodium carbonate kua. Lub melting point (Appendix VI C ntawm 2010 tsab ntawm Pharmacopoeia) yog 206 txog 212 degree, thiab nws decomposes ib txhij thaum melting. Siv cov khoom no, ntsuas kom raug, ntxiv cov tshuaj hydrochloric acid (9 → 200) kom yaj thiab ua kom muaj nuj nqis kom muaj cov tshuaj uas muaj 20 mg rau 1 mL, thiab ntsuas raws li txoj cai (Appendix VI E ntawm 2010 Edition Pharmacopoeia ), qhov kev sib hloov tshwj xeeb yog -50.0 degree rau -53.5 degree .
Adrenalinemuaj zog excitatory nyhuv ntawm ob qho tib si thiab receptors, feem ntau manifesting li nce myocardial contractility, nce lub plawv dhia, nce myocardial oxygen noj, constriction ntawm cov hlab ntsha me nyob rau hauv daim tawv nqaij mucous daim nyias nyias thiab viscera, tab sis dilation ntawm coronary thiab skeletal leeg hlab ntsha. Cov koob tshuaj sib txawv ntawm epinephrine tuaj yeem muaj lwm yam cuam tshuam rau cov hlab plawv receptors: me me ({{0}}}01-0.05ug / kg ib feeb) feem ntau txhawb nqa 1 thiab 2 receptors, nce myocardial contractility thiab cardiac outputs, dilate peripheral hlab ntsha, thaum lub receptor nyhuv tsis pom meej; Thaum cov koob tshuaj tau nce mus rau 0.1ug / kg ib feeb, ntxiv rau qhov cuam tshuam, qhov tshwm sim pom tseeb. Thaum tus nqi yog 0.1ug / kg ib feeb, a-receptor yog qhov tseem ceeb heev, thiab nyob rau tib lub sijhawm, nws qhia tau hais tias muaj zog ntawm constricting peripheral hlab ntsha, uas yog ib qho yooj yim los ua. Ua rau tachycardia thiab arrhythmias. Kev siv cov tshuaj epinephrine hmoov yuav raug txiav txim siab hauv cov neeg mob uas muaj septic shock nyob rau hauv cov xwm txheej hauv qab no: ① norepinephrine tsis zoo; ② hemodynamically manifested raws li tsis tshua muaj lub plawv tso zis, thiab tsis tshua muaj peripheral vascular tsis kam nyob rau hauv cov neeg mob uas tsis tshua muaj siab tso zis tom qab lub plawv phais yuav siv tau ib leeg los yog ua ke nrog rau lwm yam vasoactive tshuaj.Yog hais tias koj xav tau ntau.ntshiab adrenaline hmoov,thov hu rau peb.
