摘要：
The present invention is directed to compositions comprising at least one nitric oxide donor and at least one second therapeutically active agent with antimicrobial or wound healing capability. In one embodiment, the nitric oxide donor is a nanoparticle which is designed to control for the amount and duration of release of nitric oxide. The nanoparticle may further comprise the additional therapeutically active agent. The composition is useful for enhancing wound healing and for treating and preventing microbial infection. In one embodiment, the composition is directed toward reducing oral bacteria or dental plaque. The combination of one or more nitric oxide donors and one or more additional therapeutically active agent results in unexpected synergistic effects, wherein both the antimicrobial efficacy of the nitric oxide and the antimicrobial or wound healing efficacy of the second therapeutically active agent are enhanced. As a result, a patient may benefit from reduced dosage requirements and a reduced likelihood of antimicrobial resistance. The composition may be formulated for local or systemic administration, for topical applications as well as for use in coatings for medical supplies and devices.
