Oral corticosteroid potency comparison

Corticosteroids have been used as drug treatment for some time. Lewis Sarett of Merck & Co. was the first to synthesize cortisone, using a complicated 36-step process that started with deoxycholic acid, which was extracted from ox bile . [43] The low efficiency of converting deoxycholic acid into cortisone led to a cost of US $200 per gram. Russell Marker , at Syntex , discovered a much cheaper and more convenient starting material, diosgenin from wild Mexican yams . His conversion of diosgenin into progesterone by a four-step process now known as Marker degradation was an important step in mass production of all steroidal hormones, including cortisone and chemicals used in hormonal contraception . [44] In 1952, . Peterson and . Murray of Upjohn developed a process that used Rhizopus mold to oxidize progesterone into a compound that was readily converted to cortisone. [45] The ability to cheaply synthesize large quantities of cortisone from the diosgenin in yams resulted in a rapid drop in price to US $6 per gram, falling to $ per gram by 1980. Percy Julian's research also aided progress in the field. [46] The exact nature of cortisone's anti-inflammatory action remained a mystery for years after, however, until the leukocyte adhesion cascade and the role of phospholipase A2 in the production of prostaglandins and leukotrienes was fully understood in the early 1980s.

Corticosteroids, including EMFLAZA, readily cross the placenta. Adverse developmental outcomes, including orofacial clefts (cleft lip, with or without cleft palate ) and intrauterine growth restriction , and decreased birth weight, have been reported with maternal use of corticosteroids, including EMFLAZA, during pregnancy. Some epidemiologic studies report an increased risk of orofacial clefts from about 1 per 1000 infants to 3 to 5 per 1000 infants; however, a risk for orofacial clefts has not been observed in all studies. Intrauterine growth restriction and decreased birth weight appear to be dose-related; however, the underlying maternal condition may also contribute to these risks (see Data ). The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. In the . general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

Oral and injectable systemic corticosterois are steroid hormones prescribed to decrease inflammation in diseases and conditions such as arthritis (rheumatoid arthritis, for example), ulcerative colitis, Crohn's disease, asthma, bronchitis, some skin rashes, and allergic or inflammatory conditions that involve the nose and eyes. Examples of systemic corticosteroids include hydrocortisone (Cortef), cortisone, prednisone (Prednisone Intensol), prednisolone (Orapred, Prelone), and methylprednisolone (Medrol, Depo-Medrol, Solu-Medrol). Some of the side effects of systemic corticosteroids are swelling of the legs, hypertension, headache, easy bruising, facial hair growth, diabetes, cataracts, and puffiness of the face.
