Acetaminophen yog dab tsi?
Acetaminophen yog dawb crystalline los yog crystalline hmoov nyob rau hauv tsos nrog melting point ntawm 168 ℃ to 172 ℃, odorless, me ntsis iab saj, dawb soluble nyob rau hauv dej kub los yog ethanol, yaj nyob rau hauv acetone, xyaum insoluble nyob rau hauv dej txias thiab roj av ether. Nws ruaj khov hauv qab 45 ℃ tab sis yuav tau hydrolyzed rau hauv p-aminophenol thaum raug huab cua ntub, ces oxidized ntxiv. Cov xim qib maj mam los ntawm liab mus rau xim av tom qab ntawd mus rau xim dub, yog li nws yuav tsum tau muab kaw thiab khaws cia rau hauv qhov chaw txias thiab qhuav.Acetaminophen muaj cov tshuaj tua kab mob los ntawm inhibiting cov synthesis ntawm hypothalamic thermoregulation prostaglandins thiab nws lub zog ntawm antipyretic nyhuv zoo ib yam li cov tshuaj aspirin.
Kev thov kho mob
Piv nrog rau cov tshuaj aspirin, Acetaminophen muaj qhov khaus me me, ob peb qhov kev tsis haum tshuaj thiab lwm yam zoo. Nws cov nyhuv antipyretic thiab analgesic zoo ib yam li phenacetin, thiab kev siv ntawm Acetaminophen nce vim txwv los yog txwv tsis pub siv phenacetin nyob rau hauv ntau lub teb chaws.Nyob rau hauv kev kho mob, nws yog tsuas yog siv rau kub taub hau thiab mob taub hau los ntawm tus mob khaub thuas thiab relieving mob me mus rau nruab nrab mob xws li kev sib koom tes. mob, mob nqaij, neuralgia, migraine, dysmenorrhea, mob cancer, postoperative analgesia thiab hais txog. Nws tuaj yeem siv rau cov neeg mob uas tsis haum rau cov tshuaj aspirin, tsis haum rau cov tshuaj aspirin, lossis tsis haum rau cov tshuaj aspirin, xws li cov neeg mob varicella, hemophilia thiab lwm yam kab mob hemorrhagic (cov neeg mob uas muaj cov tshuaj tiv thaiv coagulant suav nrog), nrog rau cov neeg mob uas muaj mob peptic ulcer thiab gastritis. . Tsis tas li ntawd, nws kuj tuaj yeem siv rau kev sib txuas ntawm benorylate thiab siv los ua asymmetric synthetic intermediates, cov tshuaj yees duab thiab stabilizer ntawm hydrogen peroxide.
