Drugs are often taken together with meals and there are numerous opportunity for food-drug interaction to occure. Food-drug interactions and their clinical consequences are very complex indeed. The composition of the meal, and the volume of fluid that is ingested often are decisive factors in food-drug interactions. Various formulations of a specific drug may behave differently. Solutions and suspensions seem to be less susceptible and enteric-coated preparations are more susceptible, to food interactions than are other dosage forms but exceptions to this rule do exist. Furthermore, generic and environmental factors, disease and other drugs cause considerable inter- and intraindividual variation in food-drug interactions. Also, eating habits are dissimilar in different parts of the world, and diets often vary greatly from day to day. The taking of drugs together with meals offers some obvious benefits. It may help to reduce gastrointestinal irritation and compliance is improved. On the other hand, in some cases food interferes seriously with drug absorption. The purpose of this review is to clarify the complexity of food-drug interactions, and to discuss interactions that may be of clinical importance.

Effects on the bacteria gwoth of 96 kinds of crude drugs described in "Pen-Tsao-Kang-Mu" was investigated. Galla Rhois, Moutan Cortex Radicis, Aconiti Tuber, Euphorbiae Radix and PAeoniae Radix showed the antibacterial activity but Cnidii Rhizoma, Coicis Semen, Angelicae gigantis Radix, Asparagi Radix and Liriopes Tuber show the gwoth promoting action of all bacteria used in this experience. It can be seen that 10 kinds of crude drugs classified as poisonous plants inhibited the growth or had no effect by never promoted. 32 kinds of crude drugs as drugs acting on the gastrointestinal system showed antibacterial activity on E. coli $O_{55}$ and E. coli $O_{111}$. 18 kinds on inflammation showed antibacterial activity on Staphylococcus aureus and Sarcina lutea.

Dyspnea is a common symptom among patients with gastrointestinal cancer, and a comprehensive evaluation of their respiratory function is essential. Self-reporting aids in the assessment of the degree of dyspnea, while objective examination methods are performed to identify the potential underlying causes when subjective symptoms are present. Standard treatment protocols should be followed for potentially reversible and common causes of dyspnea, such as pleural effusion, pneumonia, airway obstruction, anemia, asthma, exacerbation of chronic obstructive pulmonary disease, pulmonary thromboembolism, or drug-induced interstitial lung disease. Careful and close monitoring is required due to the high frequency of pulmonary thromboembolism and the risk of cardiovascular accidents, drug-induced interstitial lung disease, or other complications from some anticancer drugs. In case of hypoxemia with an oxygen saturation of 90% or less, palliative treatment should comprise standard oxygen therapy such as nasal cannula, mask, or high-flow nasal cannula. If non-pharmacological oxygen therapy is not effective, pain control through systemic narcotic analgesics and anti-anxiety therapy with benzodiazepines may be helpful.

비스테로이드 소염제(non-steroidal anti-inflammatory drugs, NSAIDs)는 세계적으로 관절염과 같은 만성 통증에 가장 흔히 사용되는 약물이며 성분 및 기전에 따라 다양한 종류가 있다. 장기간 사용 시에는 소화기계 및 심혈관계 합병증 등의 다양한 부작용이 발생할 수 있는 것으로 알려져 있다. 기존의 비선택적 NSAID와 유사한 진통 효과를 지니면서 위장관계 내약성을 보완해줄 수 있는 cyclooxygenase-2 (COX-2) 선택적 NSAID가 많은 기대를 모았으나 2004년 및 2005년도에 심혈관계 안전성에 대한 우려로 rofecoxib과 valdecoxib의 허가가 취하되면서 NSAID 약물의 부작용에 관한 관심은 더욱 증가하고 있다. 따라서 각 약물의 부작용 및 상호작용을 고려하여 필요한 약물을 최소한으로 사용하는 것이 매우 중요하다. 본 논문에서는 NSAID 약물을 복용할 때 발생할 수 있는 부작용 및 각 약물의 특성을 숙지하며 비선택적 NSAID 및 COX-2 선택적 NSAID의 사용과 관련된 최근 연구 및 지침에 대해 알아보고자 한다.

A major problem with the peptide-based drugs is that these drugs must generally be administered by injection. Therefore, there is considerable research interest in alternative routes of delivery, such as buccal, nasal, gastrointestinal route and etc. Site-specific drug delivery to the colon, as an alternative to parenteral drug delivery, is of interest for the delivery of peptide-based drugs as well as the delivery of low molecular weight drugs for the treatment of colonic disease, This review describes some considerations of colon-specific drug delivery using hydrogels.

Cysteinyl leukotrienes are inflammatory mediators having important role in pathophysiological conditions such as asthma and allergic rhinitis. CysLT1 receptor mediates most of the disease regulatory actions of the CysLTs and it is been implicated in a number of inflammatory conditions including gastrointestinal and cardiovascular diseases. Hence in the present study, molecular docking of CysLT1 was performed with its potent and orally efficacious antagonist CP-199330 and CP-199331. The aim of this study was to compare the interaction of CP-199330 and CP-199331 with known drugs such as Zafirlukast, Pranlukast and Montelukast which had already showed clinical efficacy in the treatment of asthma. The residues such as TYR83, GLN274, LYS311 and SER313 were found to interact with both the antagonist and the known drugs. Also, we noticed the docking scores and interaction of the antagonists were comparable with the known drugs. Hence these antagonists could serve as better drugs for the treatment of allergy.

New oral anticoagulants (NOACs) are now widely used for the prevention and treatment of venous thrombosis, and for the prevention of stroke and systemic embolism in patients with atrial fibrillation. As compared with warfarin, NOACs have the advantage of rapid onset of action and less drug interaction. However, they carry a higher risk of gastrointestinal (GI) bleeding than warfarin. The risk of GI bleeding in patients using NOACs varies according to the type and dose of the drug. By contrast, apixaban and edoxaban are reported to carry similar risks as warfarin, and the risks with dabigatran and rivaroxaban are higher than that with warfarin. In patients using NOACs, old age, impaired renal function, impaired liver function, concurrent use of antiplatelet agents, and nonsteroidal anti-inflammatory drugs are considered major risk factors of GI bleeding, and gastroprotective agents such as histamine-2 receptor antagonist and proton pump inhibitor have preventive effects. To prevent GI bleeding associated with NOACs, the characteristics of each NOAC and the risk factors of bleeding should be recognized.

To research the trends of study about gastrointestinal (GI) disease in Korean medicine, we reviewed and analysed articles published in Korea from 2009 to 2012. From ancient to modern history, traditional plant-based medicines have played an important role in health care, especially GI tract. In spite of the great advances of moderm scientific medicine, traditional medicine is still the primary form of healing methods readily available to the majority of the people in the many countries. In fact many of today's popular drugs have their origins in traditional medicine. Therefore, we suggest that the development and improvement of Korean medicine in GI tract will make good the quality of life in our lifetime.

Type 2 Diabetes Mellitus, a chronic metabolic disorder which results from a high blood glucose level, is one of the most prevalent and costly diseases of our time. Considering increasing rates of obesity and the aging population in Korea, the number of diabetic patients is likely to rise rapidly in the future. There are five conventional diabetic drugs which work through different mechanisms; sulfonylureas, biguanide, meglitinide, alpha-glucosidase inhibitors, and thiazolidinedione. Although they all have antidiabetic effects, some side effects such as hypoglycemia, weight gain and gastrointestinal intolerance are associated with them. Incretin based therapies, utilizing glucagon-like peptide-1 (GLP-1) and dipeptidyl peptidase-4 (DPP-4) inhibitors, which have a lower risk of adverse side effects, have recently been introduced. At present PPAR-targeting drugs are being actively developed. In this research review, particular emphasis has been placed on the current trends and possible biological targets for the new generation of antidiabetic drugs.

One of the most common side effects of chemotherapeutic agents is chemotherapy-induced peripheral neuropathy (CIPN). The occurrence of CIPN is increasing as the survival rate of patients with cancer improves and the cumulative dose or duration of neurotoxic drugs increases. Approximately 30-40% of patients receiving neurologically toxic drugs experience CIPN, which eventually increases the burden of medical expenses. However, preventive measures against CIPN have not yet been established. Clinical trials have tested various drugs for the management of neuropathic pain, but only duloxetine has shown any significant effect. Further studies should evaluate nonpharmaceutical treatments, such as exercise.
