 This study demonstrated the feasibility of using intranasal implants to deliver drugs over a period of time. The implants were made from a polymer blend of lactic acid and glycolic acid, which allowed them to be dissolvable within the nose. The implants were then loaded with radioactive iodine, which was used to track the release of the drug over time. The results showed that the implants released the drug gradually over a period of four weeks, with the highest concentration being reached around day five. This study provides valuable insight into how these implants can be used to treat various diseases, such as depression and schizophrenia.
