Adrenochrome was used to make a "haemostatic drug" called Carbazochrome
Which explains why there was a patent (US Patent 4501923) for making it. It was used as a precursor for making
CARBAZOCHROME AND CARBAZOCHROME SALICYLATE
Adrenochrome, an oxidation product of adrenaline, becomes stable when combined with monosemicarbazone (adrenochrome monosemiearbazide). When combined with sodium salicylate this substance is much more soluble (carbazochrome salicylate) and is administered as a hypertonic solution which causes a brief painful stinging sensation when injected intramuscularly. Experiments in animals demonstrate a significant reduction of the normal bleeding time when adrenochrome monosemicarbazide is given (24). Because of rapid destruction and elimination in the gastrointestinal tract, the oral dose is approximately one-third of the parenteral dose. There is evidence to show that some effects of adrenochrome are inhibited by the action of antihistamines. The two forms of this drug were marketed 25 years ago at a time when the requirements of clinical pharmacology were not so stringent. Five recent randomized trials with quantification of blood loss in surgical situations failed to reveal a reduction in blood loss (25-29), and the efficacy of the substance, at least for this recommendation, is unproved. Carbazochrome does not induce sympathetic stimulation and is remarkably nontoxic.
