L-adrenaline, also known as L-Epinephrine, is extracted from the adrenal medulla of domestic animals (cattle and sheep) or synthesized by artificial methods, and has agonistic effects on both α and β receptors. Adrenaline is a hormone secreted by chromophores in the adrenal medulla. It is mainly involved in the regulation of sympathetic nervous system.

L-Epinephrine is white or off-white crystalline powder, odorless and bitter in taste. Very slightly soluble in water, insoluble in organic solvents such as ethanol and chloroform, soluble in mineral acid or sodium hydroxide solution. Unstable in neutral or alkaline aqueous solution, saturated aqueous Chemicalbook solution shows weak alkaline reaction. Its hydrochloride is commonly used, easily soluble in water, 0.1% aqueous solution pH 2.5~5.0, the product and its salt are easily decomposed and oxidized to pink to brownish red when encountering oxides, bases, light and heat.

L-adrenaline is used for allergic diseases: subcutaneous or intramuscular injection can treat allergic diseases, such as anaphylaxis, urticaria, آسم برونش, hoof lobe inflammation, و غیره. It is also effective for allergic reactions caused by immune serum and vaccines.

L-adrenaline is applied in combination with local anesthetics: 0.5~1ml of 0.1% adrenaline solution is added to every 100ml of local anesthetics to constrict local blood vessels and delay the absorption of local anesthetics, که می تواند زمان بیهوشی را طولانی کرده و واکنش سمی بیهوشی ها را کاهش دهد. 4. استفاده موضعی به عنوان داروی هموستاتیک موضعی: 1:5000~ 1:100,000 محلول به صورت موضعی برای منقبض کردن عروق خونی موضعی و توقف خونریزی مخاط بینی استفاده می شود, رحم, لثه یا محل جراحی, و غیره.
