Various functional foods, marketing health and functional effects, have been distributed in the market. These products, being in forms of foods, tablets, and capsules, are likely to be mistaken as drugs. In addition, non-experts may sell these as foods, or use these for therapy. Efforts for creating health food regulations or building regulatory system for improving the current status of functional foods have been made, but these have not been communicated to consumers yet. As a result, problems of circulating functional foods for therapy or adding illegal medical to such products have persisted, which has become worse by internet media. The cause of this problem can be categorized into (1) product itself and (2) its use, but in either case, one possible cause is lack of communications with consumers. Potential problems that can be caused by functional foods include illegal substances, hazardous substances, allergic reactions, considerations when administered to patients, drug interactions, ingredients with purity or concentrations too low to be detected, products with metabolic activations, health risks from over- or under-dose of vitamin and minerals, and products with alkaloids. (Journal of Health Science, 56, Supplement (2010)). The reason why side effects related to functional foods have been increasing is that under-qualified functional food companies are exaggerating the functionality for marketing purposes. KFDA has been informing consumers, through its web pages, to address the above mentioned issues related to functional foods, but there still is room for improvement, to promote proper use of functional foods and avoid drug interactions. Specifically, to address these issues, institutionalizing to collect information on approved products and their side effects, settling reevaluation systems, and standardizing preclinical tests and clinical tests are becoming urgent. Also to provide crucial information, unified database systems, seamlessly aggregating heterogeneous data in different domains, with user interfaces enabling effective one-stop search, are crucial.

Globally, drug side effects rank among the top causes of death. To effectively respond to these adverse drug reactions, a shift towards an active real-time monitoring system, along with the standardization and quality improvement of data, is necessary. Integrating individual institutional data and utilizing large-scale data to enhance the accuracy of drug side effect predictions is critical. However, data sharing between institutions poses privacy concerns and involves varying data standards. To address this issue, our research adopts a federated learning approach, where data is not shared directly in compliance with privacy regulations, but rather the results of the model's learning are shared. We employ the Common Data Model (CDM) to standardize different data formats, ensuring accuracy and consistency of data. Additionally, we propose a drug monitoring system that enhances security and scalability management through a cloud-based federated learning environment. This system allows for effective monitoring and prediction of drug side effects while protecting the privacy of data shared between hospitals. The goal is to reduce mortality due to drug side effects and cut medical costs, exploring various technical approaches and methodologies to achieve this.

최근 한국보건사회연구원이 국민의 의약품 사용실태를 조사한 결과에 의하면 1천명중 33명이 매일 항생제를 복용한다. 이는 OECD 회원국가의 평균치 21명보다 월등히 높은 비율로, 약물남용이 우려할 만한 수준임을 보여준다. 이 조사는 또 97년도 의료보험 환자중 병$\cdot$의원에서 58.9$\%$가 항생제를 처방받았다고 밝혔다. 폐렴구균의 70$\~$80$\%$가 항생제 남용으로 페니실린에 내성을 보였는데 이는 아시아 최고수준이다. 약물남용은 항생제 뿐 아니다. 많은 사람들이 의사처방 없이 자가처방으로 약을 구입하며, 자가처방의 절반은 감기약을 구입하는데 이 경우 부적절한 처방이 문제된다. 더구나 감기약은 1가지만으로도 남용할 경우 부작용이 많은데 `판피린과 콘택 600을 주세요` 라는 식으로 물약과 알약을 동시에 주문한다. 이와 같은 약의 중복사용은 약물의 남용효과를 더욱 크게 한다.

Objective: To examine the perceptions and attitudes toward spontaneous adverse drug reaction (ADR) reporting system among community pharmacists and identify factors that influence reporting, by implementing a survey. Methods: A structured questionnaire was developed and distributed online. Request for the survey was posted on the website of pharmacy's billing program, and the survey was conducted for 8 days. We collected the participants' response on their work environment, experience of ADR reporting, and their perception and attitude on the reporting system. Multivariate logistic regression was used to evaluate factors influencing ADR reporting. Results: A total of 382 pharmacists participated in the survey. Significant contributing factors for reporting level were age (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.84-0.96), knowledge of reporting method (OR, 53.56; 95% CI, 9.10-315.41), installation of reporting program (OR, 31.92; 95% CI, 4.16-244.75), and encouragement from the Korean pharmaceutical association (OR, 4.13; 95% CI, 1.11-15.35). Regarding the attitude toward spontaneous ADR reporting system, 'lack of time for reporting' (OR, 0.29; 95% CI, 0.15-0.53) and 'complexity of reporting procedure' (OR, 0.51; 95% CI, 0.31-0.84), were associated with a low likelihood of reporting. Conclusion: Our results indicated that the knowledge of ADR reporting method, installation of the reporting program, and encouragement from the Korean Pharmaceutical Association contribute to active reporting. It is necessary to simplify the reporting method, make the ADR reporting program user-friendly, and provide educational interventions to increase participation in spontaneous reporting by the community pharmacists.

The prevalence of obesity is increasing worldwide, and since obesity is associated with dietary factors and sedentary lifestyles, it is a disease that is readily developing in the modern population. Because obesity is accompanied by serious complications such as diabetes and cardiovascular disease, prevention and treatment are important. Currently, drugs such as liraglutide and phentermine are used to treat obesity by suppressing appetite and inducing gastrointestinal motility delay. However, various side effects may occur, including thyroid cancer, cardiovascular problems, and central nervous system disorders. Therefore, to explore an obesity treatment method with relatively few side effects, a method known as "fat browning" was introduced to change white adipose tissue into brown adipose tissue to increase energy consumption. Ongoing studies are attempting to find effective natural substances to safely induce browning. Many natural substances have been identified. The induction of browning by treatment with natural substances generally involves three mechanisms: positive control of browning-inducing factors, inhibition of differentiation into white adipose tissue, and the activation of mechanisms related to browning. In this study, we describe plant extracts with known browning-inducing effects, such as strawberry, black raspberry, cinnamomum cassia, and Ecklonia stolonifera extracts. We also summarize the underlying mechanisms of action identified thus far, including the signaling pathway mediated by these extracts to induce browning. Furthermore, the effects of brown adipose tissue generated through browning on heart disease as an endocrine organ disruptor are discussed.

Objective: This study aimed to investigate the occurrence and types of the adverse events (AEs) associated with oral fluconazole and itraconazole and factors associated with specific types of AEs. Methods: We analyzed AEs reported by community pharmacies nationwide over 10 years using the Korea Adverse Event Reporting System database. Various AE terms were categorized into 18 types, and concomitant medications were classified by drug-drug interaction (DDI) severity. The relationship between the specific type of AE and age, sex, and number of concomitant medications was investigated using multiple logistic regression analysis. Results: A total of 879 AE reports of fluconazole and 401 reports of itraconazole were analyzed; of these reports, 321 and 83 reports of fluconazole and itraconazole, respectively, described concomitant drug administration categorized as DDI severity of contraindicated or major. Women had a higher risk of psychiatric AEs associated with fluconazole use (OR, 1.587; p=0.042). Polypharmacy increased the risk for psychiatric AEs (OR, 3.598; p<0.001 for fluconazole and OR, 2.308; p=0.046 for itraconazole). In dermatologic AEs, the mean age of patients who received itraconazole was lower than that of patients who received fluconazole (46.3±16.8 vs. 54.9±15.4; p<0.001). Co-administration of fluconazole with 1-3 drugs increased the risk of neurological AEs (OR, 1.764; p=0.028). Conclusion: When using fluconazole and itraconazole, psychiatric AEs should be noted, particularly in women and in case of polypharmacy; moreover, when fluconazole is co-administered with other drugs, attention should be paid to the occurrence of neurological AEs.

Adverse drug reaction (ADR) may increase hospital admission, morbidity and mortality and adding extra cost to healthcare expenditures. AIMS: This study was performed to identify the types of ADR being reported in a tertiary hospital, and to find out the ways to improve current ADR monitoring system. To investigate the attitudes of hospital pharmacists towards, and their understanding of ADR reporting. METHODS: Of 117 reports submitted to the pharmacy department during 3 months survey period, A questionnaire survey of 75 randomly selected hospital pharmacists was conducted. RESULT: Of the report was from patients aged between 60 and 70. The medical department with the high frequency in ADR reporting was Internal Medicines $(60\%)$. The most common ADR manifestations were gastrointestinal complaints $(47.8\%)\;and\;80\%$ of the reported cases were mild in their severity. The most common drugs suspected of causing ADR were CNS drugs which accounted for $38.4\%.\;55.5\%$ of respondent were aware of the need to education and information about ADR monitoring. The important reasons for unreporting ADR were unknown of how to report ADRs $(94.6\%)$. CONCLUSIONS: An ADR reporting system based on reporting by staff pharmacists has been effective increasing the number of reported reactions and pharmacist involvement in monitoring patients for ADRs. Pharmacists have the knowledge and responsibility to contribute to ADR reporting program. A great opportunity exists for pharmacists to contribute in this area of patient care.

Tablets were conventionally used to treat choline urticaria. Disadvantages of tablets included sleep inducing problems, accessibility and reduced dosage. To address this, hydrogel containing Cetirizine HCl was manufactured. The experimental method was to measure viscosity, gel fraction, degree of swelling, content evaluation, and permeability. Studies have shown that hydrogels containing Cetirizine HCl can be directly applied to occurrence area to improve Cholinergic urticaric with minimal side effects associated with the marketable tablets. This hydrogel includes other important substances including steroids which gives it an advantage when applied on the skin, improving its accessibility. In addition, it is expected that the drug manufacturing process will be able to proceed as this hydrogel is effective even when used alone.
