“Introduction The discovery of the vasodilator role of nitric oxide (NO·) has led to a revolution in pharmacology over the past two decades which has brought considerable innovations in Amylase NO·-related therapy. Apart from helping to elucidate the mode of action of well established treatments such as nitroglycerine, the contribution of advances in NO· research have mainly exerted an effect in the clinic through advances in the understanding and application of

nitrite, a precursor to NO·. Just over a decade ago, the efficiency of NO· production by the metallo-enzyme xanthine oxidoreductase was demonstrated [1]. In vitro and under hypoxia, this enzyme is considerably more effective than nitric oxide synthase at generating NO· [1]. More recently, this phenomenon was observed for deoxyhaemoglobin [2], leading to the recent demonstration that nitrite has considerable protective effects in a range of cardiovascular conditions, including myocardial infarctions [3]. Nitrite, currently licensed for the treatment of cyanide toxicity, will undoubtedly continue to make a major clinical impact unless a serious side effect emerges. The long term benefits and risks of nitrite therapy have yet to be elucidated although Martindale: The Extra Pharmacopoeia lists the serious side effects as convulsions, cardiovascular collapse, coma and death.
