Abstract
The invention provides methods for inhibiting oxidative degradation of pharmaceutical formulations comprising at least one oxidation-susceptible active drug ingredient which methods comprise adding an oxidation-inhibiting amount of a ferrous ion source, preferably in the form of a pharmaceutical excipient, to the formulation.The invention further provides pharmaceutical formulations comprising at least one oxidation-susceptible active drug ingredient and an oxidation-inhibiting amount of a ferrous iron source, preferably in the form of a pharmaceutical excipient.The invention still further provides for the use of a ferrous ion source as an anti-oxidant in pharmaceutical formulations.
