1. Purpose of the R&D
Air pollution and various environmental changes due to rapid industrialization have brought increased respiratory diseases including cough and sputum and, therefore, the development of new medicine for respiratory diseases have been increasing all around the world. On the other hand, several component medicines were tend to be abused as common cold medicines with little specialized research. Moreover, several antitussive or expectorant components are being used indiscriminately as OTC drugs, although they are being used as ETC in advanced countries because of their well-known side effects. Major antitussive agents mostly having the narcotic effects, and when it comes to expectorant, indiscreet taking of numerous drugs cause a serious problems. Under these circumstances, we suggest that natural products are appropriate materials as a non-nacotic medicine which has no or relatively mild side effect. Therefore, we aimed to develop a new antitussive and expectorant agent from well known natural products. 2. R&D contents and results
* Clinical study
Clinical test was performed in patients with acute upper respiratory infection or inflammatory chronic bronchitis and the safety and efficacy of AG NPP709 was confirmed.
* Value-up study
Additional activity test and ingredient test were performed for investigating the possibility of expansion of use in respiratory disesase.
* Mass production process
The optimal condition for mass production was established based on the scale-up test condition. To maximize the efficiency in time and cost, production conditions and equipments regard were established, and the process validation was drawn up.
* Formulation test For stability test of drug substance and drug product, long term testing and accelerated testing were performed. Also additional dosage form test such as purification was performed.
* NDA filing
Materials for drug substance and drug product approval were documented, the finished NDA documents were submitted to KFDA and the permission for new botanical drug(ETC) were obtained.
3. Plan of further study & application
* The final aim of this study is the development of a new herbal medicine with not only superior effects in antitussive and expectorant activity but also outstanding safety; and therefore, many world-widely used drugs can be superseded by this new herbal medicine. Ultimately, the development of a new herbal medicine and entry to the market in advanced countries such as Europe can be a driving force to raise our national competitiveness in the world market.
* In the process of selection of candidate plant materials, plant material data base and extract libraries were established base on the oriental medicinal information. These data base and libraries probably be useful notonly to development of new herbal drugs butto study of natural product-originated derivatives in the future.
* This study can trigger the new herbal drug production; desire for a new drug development and production will increased and social and industrial atmosphere will be vitalized. Eventually, successful outcome of this study will highly affect to the natural product industry over-all such as cosmetics, food industry as well as pharmaceutical industry.
