According to the statistical data, stroke is about 13.9% of leading causes of death. Some herbal medicines including Paeonia lactiflora, Angelica gigas nakai and Prunus persica, etc., had been reported to be effective in preventing stroke and mBHT (Modified BoyangHwanoTang) was an advanced prescription used in Korean clinics. Orally disintegrating tablets (ODT) is useful for patients suffering from dysphagia, motion sickness, repeated emesis and mental disorders. Further, drugs exhibiting satisfactory absorption through the mucosa intended for immediate pharmacological action could be advantageously formulated in ODT. The aim of this study was to develop the most efficient ODT formulation of mBHT. Corresponding herbal medicines comprising mBHT were extracted with water for 3 hr at 95~$100{^{\circ}C}$ and then dried. mBHT extract was obtained with about 30% of yield. Subsequently, some pharmaceutical excipients such as spray-dried lactose, crospovidone, glyceryl behenate and/or cogrinded-treated arabia gum were used to achieve an immediate disintegration of mBHT ODT in oral cavity. The requirements of ODT with mechanical strength sufficient to stand the rigors of handling and capability of disintegrating within a few seconds in contact with saliva are indispensable. mBHT ODT prepared by the wet granulation method showed a disintegration time of below 30 sec.

This study is an endeavor to evaluate the risk assessment of hazardous(aflatoxin $B_1$) in medicines from oriental medical prescription which are circulated much recently. For that, twelve globular and granule types, seven liquid types of herbal medicine were bought to compare and analyze the content of aflatoxin aflatoxin B_1), which are harmful to human body. Woo Hwang Cheong Sim Hwan of Aflatoxin $B_1$ concentration lower than the standard accepted by all the products have been detected, B company(tradition) is the concentration of $1.24\;{\mu}g/kg$, C company $1.04\;{\mu}g/kg$, A company(tradition) and B company did not detect. And the general pill of aflatoxin B1 concentration lower than the standard accepted by all the products have been detected, S-1 is the concentration of $1.8\;{\mu}g/kg$, S-2 of $1.04\;{\mu}g/kg$, S-3 of $0.88\;{\mu}g/kg$, S-4 of $9.32\l\;{\mu}g/kg$, S-6 of $7.8\;{\mu}g/kg$, S-5 did not detect. All the products eundan allowed in the concentration of aflatoxin $B_1$ levels were lower than detection, D company of $0.96\;{\mu}g/kg$, E company concentration was not detected. The liquid product of aflatoxin $B_1$ concentration was found liwer than the standard accepted by all the product, L-3 concentration of $0.8\;{\mu}g/kg$, K-4 was detected in the $1.16\;{\mu}g/kg$, L-1 and L-2 is not detected, L-5 concentration of $15\;{\mu}g/kg$, L-7 is detected as $1.08\;{\mu}g/kg$ and, L-6 was not detected.

A new medical system of separation of dispensary from medical practice was started in 2000 in Korea. To expand bioequivalence-proven drug products and to ensure the credibility of the therapeutic equivalence of generic drug are hot issues in Korea. The KFDA also has a plan to revise the pharmaceutical affairs law that bioequivalence reports of all the generic prescription drugs should be submitted to the KFDA in the application for drug approval. Therefore, it becomes more necessary to develop bioequivalence-demonstrating methods for specific preparations such as topical drug products. There are some differences between US and Japanese guidances of bioequivalence studies of generic drug products for topical use. In this paper, we examined the recently published Japanese guideline, Guideline for Bioequivalence Studies of Generic Products For Topical Uses, and Q&A of the guideline, which will be references to make a guidance on bioequivalence studies of topical drug products in Korea.

Objectives : This study was performed to investigate the single oral toxicity of HBX-6 in Sprague-Dawley (SD) rats. Methods : Twenty SD rats were randomly assigned to four groups of 5 rats each and were administrated singly to female and male SD rats, as an oral dose of 2000 mg/kg. HBX-6 is a newly combined Korean herbal medicine formula 30 % Ethanol extract derived from The Dongui Bogam. Now we are developing the prescription for the aim of improving benign prostatic hyperplasia (BPH) without undesirable side effects. HBX-6 is composed of nine medicinal herbs: Aconiti Lateralis Radix Preparata, Corni Fructus, Cistanchis Herba, Psoraleae Semen, Dendrobii Herba, Morindae Radix, Cuscutae Semen, Trigonellae Semen, Foeniculi Fructus. Animals were monitored for the mortality and changes in the body weight, clinical signs, gross observation and necropsy findings for the 14 days according to "Standard for Toxicity Study of Pharmaceuticals" of Korea Food and Drug Administration (KFDA) guideline and "Acute Oral Toxicity - Fixed Dose Procedure" of OECD Test Guideline. Results : We could not find any mortality. Compared with the control group, significant weight change was not observed in the experimental group. After administration, the more common symptoms were not observed. There were no gross abnormalities in all cases. Conclusions : Taken together, these results suggest that the approximate lethal dose of HBX-6 in both female and male SD rats were considered as over 2000 mg/kg.

Obesity is psychological and socioeconomic problems as well as health problems related to physical disease and disorder. The obesity epidemic, including a marked increase in the prevalence of obesity among pregnant women, represents a critical public health problem throughout the world. Gung-Gui-Tang (GGT), a prescription of traditional Korean medicine, has been used to treat dizziness due to loss of blood as well as static blood after childbirth. However, the therapeutic potential of GGT on postpartum obesity has not been fully elucidated in an experimental model. In our research, GGT inhibited the increases of body weight and adipose tissues in postpartum mice fed a high-fat diet. GGT also inhibited the elevations of plasma lipid profiles such as triglyceride, low-density lipoprotein cholesterol, total cholesterol, and glutamate pyruvate transaminase. Overall, these results provide evidence that GGT can help to inhibit postpartum obesity and open new perspective to recover the shape of mother into the moment of conception.

High-performance liquid chromatography (HPLC) screening method revealed that a propolis product marketed as a functional food contained an undeclared substance similar to tadalafil, the active ingredient of the prescription drug Cialis$^{(R)}$ approved for the treatment of male erectile dysfunction. In order to identify the illegal additive, the propolis product was extracted with methylene chloride, and the extract was purified further using semipreparative HPLC. The chemical structure of the isolated substance was elucidated based on IR, LC/MS-ESI, and $^1H$- and $^{13}C$-NMR spectroscopy, which showed the characteristics similar to tadalafil. The only difference was the substitution of the methyl group at the piperazinedione ring of tadalafil to the amino group of the identified illegal additive.

The elderly are more likely to have chronic medical conditions that require multiple drug therapies. Purposes of this study are to reveal necessity of elderly patient education by pharmacists, and to induce appropriate policy. We carried out literature research. Taking several drugs together increases risk of drug interactions and adverse reactions. We suggest that pharmacists have the legal authority to monitor prescription for efficient drug management, pharmacovigilance system be efficiently operated, and medication education fee be provided to allow pharmacists give more time to the elderly.
