Abstract

Pharmaceutical compositions are for administration to the nasal tract. In particular, dry powder compositions are cellulose, and in particular hydroxypropylmethylcellulose (HPMC), and one or more therapeutic agents. It has been shown that administration of HPMC to the nasal cavity is capable of enhancing natural mucus. These powders, and the gel that forms when they are administered to the nasal tract, have now surprisingly been found to be a very effective way of intranasally administering therapeutic agents, and in particular, herbal or homeopathic agents.
