The present application relates to the technical field of biological
medicine, and more particularly to a
liposome dispersion liquid and ear drops for penetrating the tympanic membrane and the
inner ear round window membrane. The present application designs a
liposome dispersion liquid which can effectively penetrate the complete path of the tympanic membrane and the
inner ear round window membrane after non-invasive ear drops through the external
auditory canal, so as to avoid the tympanic membrane perforation caused by intratympanic injection and reduce the pain and discomfort of patients. The
liposome dispersion liquid of the present application has good stability, the prepared ear drops can realize efficient delivery of targeted
inner ear drugs, has the characteristics of non-invasive and convenience, and has a wide application prospect in the medical field.
