Some two years ago our company undertook a project on manufacturing network rationalization to maximize competitiveness through continuous improvement in manufacturing efficiency. One key outcome was the recognition of the benefits that could be derived from timely application of new technology or novel use of existing technologies and even more importantly the need to develop company wide strategies to maximize the impact of such applications. As a direct result an exercise was undertaken to identify the ten most promising technologies from a list of literally hundreds seen as having the capability of making a rapid impact on the manufacturing initiative. One of the outcomes of this exercise was the identification of Near Infrared Spectroscopy as a pivotal technology for improving process understanding, performance, and control to deliver consistent product quality cost effectively with broad applicability across our product range. While NIR had been in use in targeted areas on some of our sites for some years our new challenge was to develop a strategy to extend NIRs application, initially over 17 manufacturing sites, while concurrently expanding the NIR skill base company wide to ensure that the return on initial investment could be further maximized as shared applications across the remaining sites as required. This presentation will provide an overview of how life cycle based user requirement specifications were developed covering: ㆍSpectrophotometers ㆍSample interfaces ㆍSoftware ㆍEquipment and Software qualification ㆍCalibration transfer ㆍ Ease of developing effective user interfaces and control for applications transferred to a production area ㆍUser training ㆍWorld wide support The presentation will also describe the process adopted for vendor selection to ensure maximum utilization of the existing company wide NIR skill base and its future development to expedite applications of the technology in development, quality control and production areas.

To examine effects of oriental pharmaceutical preparations on immunity, four of such preparations which are currently being used were examined. After their fluid extracts were injected intraperitoneally to ICR mice, the counts of total cell number, PMN and macrophage in the peritoneal cavity were made by using non-specific esterase staining method, and plaque-forming cells (PFC) were measured by using the modified method of Cunningham and Jerne. The results showed that 'Bo-Jung-Ik-Ki-Tang', 'Ih-Jung-Tang', 'Ohn-Kyeong-Tang' and 'Ke-Ji-Bok-Ryeong-Hwan-Ka-Dae-Hwang' increased both the macrophages and the total cells of the peritoneal cavity and that these preparations increased the number of PFC in the spleen. Therefore the data indicate that they potentiate both of the cell­mediated and humoral immunities in the mice.

Background : The promotion and advertisement of pharmaceuticals should be based on evidence from clinical trials. We conducted this study to assess whether the pharmaceutical advertisement claims in Korean medical journals had relevant references, and whether the claims were supported by the references. Methods : We reviewed pharmaceutical advertisements in five Korean medical journals issued during the first half of 1999 and during the first half of 2004. Three investigators independently reviewed the advertisements to see whether the studies quoted to endorse the advertising messages supported the corresponding claims. Using multiple logistic regression analyses, we investigated which factors were associated with the quality of the advertisement claims. Results : From the 550 advertisements in the five journals, we identified 157 different advertisements and 475 different promotional claims. Only 149 claims had at least one reference, and 105 claims had references of published article. We could find supporting evidences in the 90 claims. The factors which were associated with the quality of advertisement claims were category of drugs, category of claims, and the manufacturer characteristics. Claims for cardiovascular and endocrine drugs, and claims on efficacy, and claims of multinational company were more evidence-based. Conclusion : Majority of the pharmaceutical advertisement claims in Korea did not have appropriate references. Drug category, claim category, and the manufacturer characteristics were associated with the quality of advertisement claims, and the manufacturer characteristics was the most important determinants.

Background: Our previous study demonstrated cytotoxicity of a crude extract from Patrinia heterophylla Bunge (PHEB). In the present study, we aimed to investigate the effects of isovaltrate acetoxyhydrin (IA) isolated from PHEB on the gastric cancer cell SGC-7901, in order to explore a potential treatment for gastric cancer. Methods: MTT assays were employed to determine the effects of IA on cell vitality and proliferation, with monitoring of cell morphology changes and examination of apoptosis with Annexin V-PI staining. Flow cytometry was used to assess cell cycle progression and mitochondrial membrane potential. The activity of caspase 3, 9 was evaluated by spectrophotometry, and the protein levels of Bax, Bcl2 and Cyclin B1 were analyzed with Western blotting of total proteins extracted from cultured cells. Results: The results demonstrated direct toxicity of IA towards SGC-7901 cells. Evidence of apoptosis included blebbing and chromatin condensation. Annexin V-PI assays revealed early apoptosis, involving rapid depolarization of mitochondrial membranes and activity of caspase 3, 9 signaling pathways. Western blotting showed that Bcl2 and Bax proteins was down- and up-regulated, respectively, and cyclin B1 was up-regulated. Cell cycle analysis further indicated that IA could induce G2/M phase arrest in SGC-7901 cells. Conclusions: In conclusion, we believe that IA induces apoptosis of SGC-7901 cells, therefore providing a potential therapeutic agent for treatment of gastric cancer.

Purpose - The purpose of this study is to investigate the types and forms of various marketing activities actually used in pharmaceutical companies and to empirically analyze the impact of these marketing activities on sales. Design/methodology/approach - This study categorize five years' worth of marketing activity data from a foreign pharmaceutical company 'A' which operates in South Korea into five categories. Multiple regression analysis and interaction effects are employed for data analysis. Findings - First, CRM calls, Detail calls, GP, and Web events have a positive impact on sales, but SoV does not show significant differences. Second, in the comparison between HQ1 and HQ2 based on patent ownership, Detail calls and Web events had a stronger impact on sales in HQ2, where the patent period is still in effect, compared to HQ1. However, SoV showed no difference between HQ1 and HQ2. Research implications or Originality - First, Detail Calls are more effective for drugs with active patents, while CRM Calls work better for drugs with expired patents. This emphasizes the need to customize call strategies based on patent status. Second, the significant impact of Web Events on sales in HQ2 compared to HQ1 suggests that online information access is crucial, indicating that customer receptivity varies based on product nature. Third, these insights, derived from data analysis, call for a shift in pharmaceutical marketing analysis methods away from traditional approaches. Finally, this study holds significance as one of the first empirical analyses using actual marketing data from pharmaceutical companies in South Korea.

Objectives : Since single extract powders was released at 1987, the insurance fee has not been changed, but the price of raw material has been increasing. According to this, Pharmaceutical company couldn't invest on quality of the product, so, the quality of single extracts went down and lost the consumer's trust. We checked the contents of marker ingredients in single extract thereby to recover the reliability of insurance-covered herbal preparations. Methods : we bought total twelve products of eight different single extracts of two main pharmaceutical companies among total 65 kinds of single extract powder stipulated in KHP (The Korean Herbal Pharmacopoeia) monograph III at Jan. 2013. Assays of selected single extract powders are performed by KHP regulation. And we surveyed price fluctuation of relevant herb raw materials from 2005 to 2012. Results : Among twelve products, eight single extract powders were suitable by the KHP regulation. But four products didn't reach the content amount of KHP. Marker contents in the single extracts product of Pueraria Root, Licorice, Peony root and Scutellaria Root of A company were 70%, 1%, 23.7% and 75.1%, respectively. Conclusions : We can acertain whether there's a quality problem in the insurance-covered single extract powders. But, A company is no longer producing these improper single extract powders. As a medicine, single extract powders needs to be strictly quality controlled by the company, and regularly monitored by the KFDA.
