Corticosteroids examples

A corticosteroid is a type of medication that is often referred to as a steroid. This powerful medication is used to treat inflammation . For example, it may be used to treat such things as swelling and redness. These medications are also used to treat itching that occurs as the result of allergies or other types of conditions. A doctor may prescribe them for treating a range of illnesses and conditions, including asthma , arthritis, and certain diseases; they are also prescribed for people who are dealing with severe allergies and certain conditions that affect the skin.

Direct intravenous injection:
Use only methylprednisolone sodium succinate.
Reconstitute with provided diluent or add 2 ml of bacteriostatic water (with benzyl alcohol) for injection.
May be administered undiluted.
Administer directly into a vein over 3—15 minutes. Doses >= 2 mg/kg or 250 mg should be given by intermittent infusion (see below), unless the potential benefits of direct IV injection outweigh the potential risks (., life-threatening shock).
 
Intermittent intravenous infusion:
Use only methylprednisolone sodium succinate.
Dilute in D5W, % Sodium Chloride (NS), or D5NS injection. Haze may form upon dilution.
Infuse over 15—60 minutes. Large doses (., >= 500 mg) should be administered over at least 30—60 minutes.

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.
