The addition of low concentrations of combinations of water-soluble organic salts of zinc to gels, creams, lotions or ointments can increase the ability of these products to reduce or prevent exogenous irritants from causing irritation of the underlying substrate. The addition of low concentrations of combinations of water-soluble organic zinc salts to these gels, creams, lotions or ointments also can reduce the irritation of skin or mucous membranes caused by the addition of potentially-irritating substances such as spermicides, microbicides, fungicides or other therapeutic agents to the gel, cream, lotion or ointment. The advantages of this anti-irritant approach over others, which generally employ high concentrations of single zinc salts, are the reduced potential for zinc toxicity, the reduced potential for toxicity related to zinc itself, and the preservation of the desirable biological properties of potentially-irritating therapeutic substances added to the gel, cream, lotion or ointment.

Topical exposure of nitric oxide gas to wounds such as chronic non-healing wounds may be beneficial in promoting healing and preparing the wound bed for further treatment and recovery. Nitric oxide gas may be used to reduce the microbial infection, manage exudates secretion by reducing inflammation, upregulate expression of endogenous collagenase to locally debride the wound, and regulate the formation of collagen. High concentration of nitric oxide ranging from 160–400 ppm may be used without inducing toxicity in the healthy cells around a wound site. Exposure to the high concentration for a first treatment period reduces the microbial burden and inflammation, and increases collagenase expression to debride necrotic tissue at the wound site. After a first treatment period, a second treatment period at a lower concentration of nitric oxide, preferably ranging from 5–20 ppm may be used to restore the balance of nitric oxide and induce collagen expression aiding in the wound closure.
