Abstract: The present invention relates to a concentrated melatonin solution, wherein melatonin is present in a quantity of 10.0% or higher in a substantially water-free carrier mixture of ethanol and a polyethoxylated derivative. The concentrated solution, free of preserving agents, is suitable to prepare injectable sterile compositions for parenteral administration, or formulations for topical or oral administration. The invention also encompasses a method for the preparation of the concentrated solution, as well as the possible benefits of the intravenous infusion of high levels of melatonin as adjuvant therapy in Ebola or Dengue hemorrhagic fever (DHF) or as an anti-oxidant/anti-aging treatment.
