Objectives: This paper was aimed to investigate the adhesion control standards of pain relieving patch (PRP) drugs and to survey it's adverse effects on the skin of patients for safe use of PRP drugs. Methods: In this study, the related documents of PRP drugs of Korea pharmacopoeia (KP), United States pharmacopoeia (USP), Japanese Pharmacopoeia (JP), European pharmacopoeia (EP), and information web sites of the Ministry of Food and Drug Safety (MFDS) were surveyed. Also, the past and current labeling of PRP drugs marketed in the pharmacy was investigated and compared. Results: In KP and JP, the lower limit standard for PRP's adhesion control is established, but the upper limit standard is not designated. In USP and EP, neither the lower nor upper limit standard is established. The main reasons of skin adverse effects are considered as inherent adverse reactions of the applied drugs for PRP. Another reason is involved in patient's medication mistakes related to PRP's adhesion control, respiratory depression of skin according to physical skin closure, and microbial growth, etc. Conclusion: For safe use of PRP drugs, we proposed ensured guidelines like additional instructions of pharmacist's prescription and detailed labeling systems for usage of PRP drugs applied on skin.

Background: Under the risk of financial sustainability of National Health Insurance, Korean government attempted a series of regulations over pharmaceutical prices. The first price-cut was implemented to the hyperlipidemial treatments, and the prices of statins were reduced on 15th, April in 2009. The purposes of this study are 1) to investigate the impact of this price-cut on pharmaceutical expenditure, and 2) to identify the factors associated with drug-switch among statins. Methods: Using the national patients sample data, this study conducted time series analysis on the expenditures, prices, and volumes of statin drugs. To understand the factors associated with drug-switch, the multinomial logit model was analyzed at the patients level. Results: The results of time series analysis demonstrated that the price-cut of hyperlipidemic medicines did not lead to the reduced expenditure, suggesting the increased volume was the major cause. The multinomial logit analysis identified the switch of healthcare provider as the significant factor that was highly associated with drug-switch, implying the physicians' preference was the major motivation of drug-switch. Conclusion: Without control of utilization, price regulation itself could not reduce pharmaceutical expenditure. This suggests that the pharmaceutical regulations should be implemented on the basis of understanding of provider behaviors. The findings of this study will form the first step for further empirical studies.

최근 인간의 생명 연장과 건강 등에 관심이 많아지면서 약학 및 의학계는 생체 내에서 보다 안정적이며 효과를 나타낼 수 있는 약물 전달 시스템의 개발에 많은 힘을 기울이고 있는 실정이다. 수많은 생화학 연구자들은 키토산이 인체에 거부반응이 없으며 약물과 백신의 전달을 효율적이고 안전하게 흡착능력을 향상시킨다는 것을 밝혀 왔다. 또한 그것은 생분해성, 생체 친화적이라는 장점 때문에 약물 방출 조절에 적당하다고 알려져 있다. 본 연구에서는 생명고분자인 키토산의 나노입자를 제조하여 농도, pH, 최적 온도에서 약물 전달 조절을 in vivo 조건에서 수행하였다. 인슐린을 담지한 키토산 나노입자는 당뇨성 쥐의 혈당을 효과적으로 낮춰 줄 수 있음을 알 수 있었다.

This paper develops a pump system for patient with chronic pain or cancer. The pump module is consists of two micro-valve and membrane. The micro-valve is operated by a solenoid. With two solenoid valves which are connected via a drug transport line, the inlet and outlet are completely blocked. A silicon rubber membrane located between the two valves makes the flow-rate constant without any backflow. This pump module can control the flow-rate of drugs by controlling the time that the valves are opened and closed. The reservoir consists of a drug chamber and a gas chamber. As the gas chamber encloses the drug chamber, propellant gas which is injected into the gas chamber pressurizes the drug chamber regardless of volume of the drug chamber. To design the pump module, analysis a constant efficiency test, and accuracy test for the pump module were conducted.

Di-n-butyl phthalate (DBP) is not only a plasticizer and solvent used in industry but also one of endocrine disruptor chemicals, a low level contaminant found in a wide variety of different media ranging from drinking water to infant formulae. To evaluate the cytotoxic function of NK cells in mice after contact with DBP, C57BL/6 female mice were orally dosed with di-n-butyl phthalate (250, 500, or 750 mg/kg body weight) for 14 consecutive days, and the control mice were administered vehicle (corn oil).(omitted)

In order to monitor the anticancer drug in stable conditions, the Web based anticancer drug management system and alarm services were constructed and assessed in this study. Anticancer drug should be exact to the correct patient in the right environment. To overcome the restriction of existing equipment that only monitors fragmentarily, temperature and humidity were continuously monitored to maintain stable environments using sensor networks and RFID for the monitoring and management of anticancer drug. Construction drug identification and the effect of normal air outside the anticancer dispensary with obstacles were evaluated in working hour. Pre-installed control system in the dispensary could be alternated with auto sensing and alarming. We expected that the efficiency of anticancer drug management and the reliability of drug medication by handwork would be increase accordingly.

In this paper, I tried to pursue health and social welfare together through medical convergence based on the main subject of a culture of convergence. Artists' drug accidents are never ending. Now Korea is also out of the drug cleansing country. it is impossible to get rid of them with the national public power. It is time for a treatment plan for these. They need a certain period of time and regular periods of rest and control over sports. Our humanities are researching to understand the changing human images of today. In parallel, medical convergence will also have to be transformed in various ways for human healing. Recently, we can see the case of healing with the combination of oriental medicine, natural healing and western medicine. Furthermore, the structure of medical convergence for the fight against disease can be analyzed as an example. South Korea is also preparing for various convergence programs focusing on natural sciences such as engineering, medical care, and the environment. In order to prevent drug addiction it is important to determine the department responsible for handling the problem of substance abuse. we need to improve the environment that they can be combined with Ondol therapy and natural healing therapies. Furthermore, I expect that fusion medicine will contribute to improving the quality of life of drug addicts and become a successful model to revitalize local economies in particular.

The purpose of this study was to investigate the effect of nifedipine (10 mg/kg) on the pharmacokinetic parameters and the bioavailability of paclitaxel (50 mg/kg) orally coadministered and pretreated in rats. The plasma concentration of paclitaxel in combination with nifedipine was significantly (p<0.05 at 10 mg/kg coadmin., p<0.01 at pretreat.) increased compared to that of control, from 2 hr to 24 hr. Area under the plasma concentration-time curve (AUC) of paclitaxel with nifedipine was significantly (p＜0.05 at 10 mg/kg coadmin., p＜0.01 at pretreat.) higher than that of control (omitted)
