Abstract
A composition provides an isotonic nasal irrigation solution with pH less than about 7.0. The composition may be formed of a salt and a pH buffer and may include an additive. The composition may be mixed with water to form the solution. The composition may aid in the treatment of various nasal or sinus disorders such as, for example, dryness, rhinitis, and sinusitis. The isotonic irrigation solution may also aid in the removal of contaminants from the sinus and nasal cavities such as blood, mucus, dirt, pollen, allergens, viruses, and bacterial. The composition may be liquid or dry.
Claims23
A nasal wash composition comprising
- a salt;
- and
- a pH buffer, wherein
- when the salt and the pH buffer are mixed with a prescribed volume of water an isotonic solution of pH below 7.0 is produced.
A method of preparing a nasal wash solution comprising:
- combining
- a pre-determined amount of a salt, and
- a pre-determined amount of a pH buffer, and
- a pre-determined volume of water,
- to create an isotonic solution, wherein said solutions has a pH of below 7.0, thus preparing a nasal wash solution.
A method of treating a nasal or sinus condition comprising
- combining an amount of nasal composition with a volume of water to create a salt solution with a pH below 7.0, wherein the ratio of composition to water is about 1:100;
- and
- introducing the isotonic salt solution into the sinus or nasal cavities of a patient in need of such treatment.
