코르티존 화학적 특성, 용도, 생산

화학적 성질
Off-White Crystalline Powder
용도
Cortisone is used for inflammatory processes, allergies, and adrenal insufficiency.
정의
ChEBI: A C21-steroid that is pregn-4-ene substituted by hydroxy groups at positions 17 and 21 and oxo group at positions 3, 11 and 20.
일반 설명
Cortisone is a corticosteroid produced in the adrenal glands. Cortisone is administered for short term pain relief and to reduce swelling from inflammation. This Certified Spiking Solution^? is applicable in LC-MS/MS applications for endocrinology, clinical chemistry and neonatal screening.
위험도
Damaging side effects, e.g., sodium retention from ingestion.
Pharmacokinetics
Following oral administration, cortisone acetate and hydrocortisone acetate are completely and rapidly deacetylated by first-pass metabolism. Much of the oral cortisone, however, is inactivated by oxidative metabolism before it can be converted to hydrocortisone in the liver. The pharmacokinetics for hydrocortisone acetate is indistinguishable from that of orally administered hydrocortisone. Oral hydrocortisone is completely absorbed, with a bioavailability of greater than 95% and a half-life of 1 to 2 hours (23).
Clinical Use
Cortisone is administered orally or by intramuscular (IM) injection as its 21-acetate (cortisone acetate).Cortisone acetate or hydrocortisone usually is the corticosteroid of choice for replacement therapy in patients with adrenocortical insufficiency, because these drugs have both glucocorticoid and mineralocorticoid properties.
신진 대사
The metabolism of hydrocortisone has been previously described. Cortisone acetate is slowly absorbed from IM injection sites over a period of 24 to 48 hours and is reserved for patients who are unable to take the drug orally. The acetate ester derivative demonstrates increased stability and has a longer duration of action when administered by IM injection. Thus, smaller doses can be used. Similarly, hydrocortisone may be dispensed as its 21-acetate (hydrocortisone acetate), which is superior to cortisone acetate when injected intra-articularly.
Purification Methods
Crystallise cortisone from 95% EtOH or acetone. The UV has 14,000 M-1cm -1 at 237nm (EtOH). [Beilstein 8 IV 3480, Hems J Pharm Pharmacol 5 409 1953, Beilstein 8 IV 3480.]
