Corticosteroid iv to po conversion

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.
