Abstract

The present disclosure features methods and compositions for enhancing the ability of the respiratory membranes to filter airborne pathogens and protect a subject from respiratory infections that result from inhalation or ingestion of such pathogens. In particular, the disclosure provides antimicrobial compositions that prevent and treat respiratory infections caused by bacteria, fungi, and viruses.

Claims (17)

1. A pharmaceutical composition comprising one or more pharmaceutically acceptable carriers or excipients, a first active agent that is ICAM-1, and a second active agent that is a combination of lactoferrin and lysozyme;

wherein said composition is in the form of a nasal spray, nasal drops, oral spray, oral rinse, or lozenge having a suitable viscosity to possess a residence time on the mucosa of the nasal or oral cavities of at least 1 minute; and

said first and second active agents are present in said composition in individual form,

the weight ratio of said first active agent to said second active agent is about 1:100 to about 1:200 and

the weight ratio of lactoferrin to lysozyme is about 1:4 to about 1:20.

2. The pharmaceutical composition according to claim 1 , further comprising one or more of zinc peroxide, copper, and silver.

3. The pharmaceutical composition according to claim 1 , further comprising carrageenan.

4. The pharmaceutical composition according to claim 1 , further comprising one or more ingredients selected from the group consisting of marshmallow extract, Calendula extract, citrus peel extract, honey extract, rosemary extract, myrrh extract, Helichrysum extract, arrowroot extract, neem oil, vitamin C, vitamin E, and grapefruit seed extract.

5. The pharmaceutical composition according to claim 1 , wherein the composition is a lozenge.

6. The pharmaceutical composition of claim 1 , wherein said pharmaceutical composition comprises from about 0.0000001% to 0.1% soluble ICAM-1 by weight of the composition.

7. The pharmaceutical composition of claim 1 , wherein said pharmaceutical composition comprises from about 0.000001% to 0.01% soluble ICAM-1 by weight of the composition.

8. The pharmaceutical composition of claim 1 , wherein said pharmaceutical composition comprises from about 0.0000001-1.0% soluble lactoferrin by weight of the composition.

9. The pharmaceutical composition of claim 1 , wherein said pharmaceutical composition comprises from about 0.000001-1.0% lysozyme by weight of the composition.

10. The pharmaceutical composition of claim 1 , wherein said pharmaceutical composition comprises

from about 0.000001% to 0.01% soluble ICAM-1 by weight of the composition,

from about 0.0000001-1.0% soluble lactoferrin by weight of the composition, and

from about 0.000001-1.0% lysozyme by weight of the composition.
