Application and research progress of traditional Chinese medicine
delivered via nasal administration
Abstract
Nasal administration of traditional Chinese medicine (TCM) has a long
history of application. With the gradual maturing of technology and
pharmacological advances, nasal preparations of TCM have undergone
significant changes. Nasal TCM formulations are used not only for
treatment of pneumonia, asthma, sinusitis and allergic rhinitis but also
Alzheimer’s disease and Parkinson’s disease, as antidepressants and
antiepileptics, and in ischemia reperfusion. In this study, we reviewed
the development and application of different nasal preparations of TCM
from the aspects of nasal structure, origin, factors affecting
absorption and common dosage forms, pharmacodynamics, pharmacokinetics
and safety. In the near future, we expect that more nasal preparations
of Chinese medicine with independent intellectual property rights will
be marketed to meet the needs of clinical disease management.
