| abstract |
A method of facilitating the obtaining of a mucus sample from at least one lung of a subject comprises administering to at least one lung of the subject, in an amount effective to hydrate lung mucus secretions and/or stimulate cilia beat frequency therein, uridine 5'-triphosphate, an active analog thereof, or a pharmaceutically acceptable salt of either thereof, and, optionally, concurrently administering to said at least one lung a physiologically acceptable salt in an amount effective to hydrate lung mucus secretions therein. A sputum or mucus sample is then collected from said at least one lung, which sample can then be analyzed for lung disease. Pharmaceutical compositions useful for carrying out the method comprise UTP or a salt thereof, alone or in combination with a physiologically acceptable salt, or a pharmaceutically acceptable salt of either thereof. The composition may be a liquid/liquid suspension composition or a dry powder composition. |
