Abstract:
INTRODUCTION:Oxidative stress toxicity (OST) has been implicated in almost all pathological conditions. Despite the widespread use of natural antioxidants, no pharmaceutical antioxidants have yet been developed or prescribed in medical practise. Antioxidant drugs such as Deferiprone and N-acetylcysteine can target essential pathways of OST in many pathological conditions. The pharmacological parameters required by antioxidant drugs in relation to the OST target characteristics include the determination of the therapeutic index, ADMET and drug interactions. Antioxidant drug development efforts are currently targeting the treatment of severe diseases with no proven effective therapies. AREAS COVERED:This article addresses the damaging effects of OST, prospects for the development of pharmaceutical antioxidants and clinical studies using other drugs with antioxidant potential. EXPERT OPINION:Effective antioxidant therapeutic strategies should include the design of protocols for the inhibition of OST through iron chelation, administration of synthetic and natural antioxidants and enhancement of the antioxidant defences by increasing the production of endogenous antioxidants and activation of antioxidant mechanisms. Different therapeutic strategies apply in the use of antioxidant drugs for one or more targets, for prevention, treatment, or of post-treatment effects and for systematic, long-term or short-term applications. The design of new antioxidant drugs and effective protocols which can include Deferiprone and N-acetylcysteine combinations, could lead to the development of a new class of therapeutics for clinical use.
