Lewis Sarett of Merck & Co. was the first to synthesize cortisone, using a 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.

The invention concerns a pharmaceutical composition in the form of a film-shaped system for transmucosal delivery of steroid hormones. The invention concerns in particular a system for delivering steroid hormones which dissolves in the oral cavity and releases the active substances with high bioavailability. Said film-shaped delivery system dissolves in the oral cavity preferably in less than 30 minutes, the steroid hormone which passes through the trasmucosal route of the delivery system to a blood circuit rapidly increasing concentration in the blood. The steroid hormone concentration in the blood can reach a maximum level in less than 60 minutes after delivery.
