<p>Adrenochrome Monosemicarbazone is a haemostatic with a rapid onset of action. It contains a water soluble form of adrenochrome monosemicarbazone, a stable derivative of adrenochrome as the active substance. Adrenochrome is an oxidation product of adrenaline; it reduces normal and pathologic bleeding time by decreasing capillary permeability. It produces capillary haemostatis without exerting any of the adrenergic actions on respiration or cardiovascular system. Thus, despite its adrenaline like action on small blood vessels, does not give rise to the general systemic effects of sympathomimetic drugs.</p>
