Abstract
A moisture or hydrating liquid activatable solid formulation for nitric oxide (NO) generation includes a nitrite source; a copper (I) or copper (II) catalyst; an NO generation accelerant; and a solid pH buffer. The nitrite source is to generate NO when exposed to an effective amount of moisture or a hydrating liquid. The pH buffer is present in an amount sufficient to render a pH of the moisture or hydrating liquid activatable solid formulation from greater than 4 to about 9.0.
