Purpose: Nonsteroidal anti-inflammatory drugs that prohibit biosynthesis of arachidonic acid metabolites have been considered potent host modulation agents. The aim of this review was to determine the effect of nonsteroidal anti-inflammatory drugs adjunctive with nonsurgical periodontal treatment in patients with periodontal disease. Materials and Methods: Three electronic databases were searched to identify relevant studies. The methodological quality and mean differences of the change in clinical attachment level and probing depth were analyzed according to Cochrane review methods. Results: Twelve studies were included in the methodological assessment and nine studies were suitable for inclusion in the meta-analysis. The mean difference in the clinical attachment level gain did not differ significantly between the nonsteroidal anti-inflammatory drugs and control groups at any observation time. The highest mean difference in clinical attachment level gain was 0.30 mm at 4 weeks (95% confidence interval = -0.37 to 0.97). There was a significant mean difference in the probing depth reduction, of 0.34 mm (95% confidence interval = 0.29 to 0.40) at 6 weeks. Conclusion: Therefore, nonsteroidal anti-inflammatory drugs have additional therapeutic effect when administrated with nonsurgical periodontal treatment.

Verapamil is a calcium channel blocker and is classified as a class IV anti-arrhythmic agent. It is used in the control of supra ventricular tachyarrhythmias, and in the management of classical and variant angina pectoris. It is also used in the treatment of hypertension and used as an important therapeutic agent for angina pectoris, ischemic heart disease, hypertension and hypertrophic cardiomyopathy. Verapamil commonly co-administered with NSAIDs (non-steroidal anti-inflammatory drugs) i.e. diclofenac sodium, flurbiprofen, Ibuprofen, mefanamic acid and meloxicam. A simple and rapid RP-HPLC method for simultaneous determination and quantification of verapamil and NSAIDs was developed and validated. The mobile phase constituted of acetonitrile: water (55:45) whose pH was adjusted at 2.7 and pumped at a flow rate of 2.0 mL $min^{-1}$ at 230 nm. The proposed method is simple, precise, accurate, low cost and least time consuming for the simultaneous determination of verapamil and NSAIDs which can be effectively applied for the analysis of human serum.

Objectives : To investigate the utilization patterns of non-steroidal anti-inflammatory drugs (NSAIDs) among the elderly with osteoarthritis (OA) undergoing primary ambulatory care in Busan metropolitan city, Korea. Methods : OA patients, aged 65 years and over, were identified from the Korean National Health Insurance Review Agency drug prescription database. The subjects had at least one episode of claim for OA (ICD-10-CM: M15-M19) between August 1, 2000 and February 28, 2002. Trends in the determinations of NSAIDs utilization were identified using chi-squared tests for trend. Results : There were 47,711 osteoarthritic patients. The total number of visits by these patients was 177,443, with a total frequency for NSAID prescriptions of 214,952. Seventy-nine percent of the OA patients were female. NSAIDs were prescribed on 133,284 visits (75.1%) and the proportion of prescriptions was significantly increased with age. Only the proportion of visit when NSAIDs were prescribed decreased, from 65.1 to 43.5%, during the study period (p<0.001). However, the proportion of combined treatments with anti-ulcer drugs was increased. The use of NSAIDs injections was decreased. Of the individual NSAIDs, diclofenac (28.7% of total frequency of NSAID prescriptions), piroxicam (15.0%) and talniflumate (8.7%), were the most frequently prescribed. Among the NSAIDs prescribed OA visits, 45.7% used two or more NSAIDs. Conclusion : The total proportion of NSAIDs prescribed to the osteoarthritic patients was higher than in other studies. The decline in the use of NSAIDs during the study period, and the frequent selection of safer medications, such as combination therapy with anti-ulcer drug, may reflect the risk awareness of the use of NSAIDs.

In this study, we analyzed the anti-oxidative and anti-inflammatory activities of seven medicinal herbs. All extracts of the tested herbs, Euryale ferox Salisbury, Echinops setifer Iljin, Amomum cardamomum Linne, Tetrapanax papyriferus, Illicium verum Hook. f., Typha orientalis Presl, and Piper longum Linne, exhibited potent anti-oxidative activity as confirmed by DPPH radical scavenging capacity. Lipopolysaccharide (LPS) induced nitric oxide (NO) production, in the RAW 264.7 cell line, was also ameliorated by all extracts' treatments in a dose dependent manner. NO suppressive activity originated from the inhibition of inducible nitric oxide synthase (iNOS) protein expression by the extracts. Three extracts, E. ferox S., I. verum Hook. f., and P. longum L., possessed suppressive activity against, not only iNOS, but also cycloxygenase 2 (COX-2) protein expression. These three extracts may then serve as potential candidates for non steroidal analgesic inflammation drugs (NSAIDs). Furthermore, all extracts induced anti-oxidative enzyme, heme oxygenase 1, protein expression. Taken together, these results provide an important new insight into the fact that various medicinal herbs possess potent anti-oxidative and anti-inflammatory activities and might be utilized as promising agents in the field of health products. Further studies for the identification of the active compounds from medicinal herbs are clearly needed.

Purpose : The purpose of this study was to evaluate the prescription pattern of NSAIDs and GPAs in the arthritis patients over 65 years old to prevent the GI adverse events. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly used agents to treat arthritis, can cause gastrointestinal (GI) adverse effects. Recent guidelines recommend that moderate risk patients who have one or two risk factors, should be prescribed either combination of non-selective NSAID (nsNSAIDs) and gastroprotective agent (GPAs) or selective NSAID alone. Methods : Study population was National Patient Sample of 2011. Number of drugs used were 138 for NSAIDs and 21 for GPAs. Chi-square test was used to compare prescribing patterns. Results : The appropriate prescription rate follows the guideline was 11.2%: co-prescription with nsNSAID and proton pump inhibitor (PPI) or misoprostol was 1.6% and selective NSAID alone was 9.6%. Inappropriate prescription rates were as follows: co-prescription with nsNSAID and Histamine-2 receptor antagonist (H2RA) or antiacid was 53.8% and nsNSAID alone was 35.0%. The appropriate prescription rate among the types of medical institute was 54.4% in tertiary hospital, 31.2% in secondary hospital, and 6.0% in primary hospital. The appropriate prescription rate among the regions was 19.4%, highest in Seoul and 4.2%, lowest in Jeju. The appropriate prescription rate among the medical departments was as follow: 12.2% in orthopaedic surgery, 11.0% in internal medicine, and 7.7% in other departments. Conclusion : This finding suggests the needs to revise the national medical insurance imbursement policy, provide continuing medical education about the guideline of medical doctors.

Purpose: There are very few reports of adverse drug reactions (ADR) and almost no study of drug provocation test (DPT) in Korean children. We aimed to assess the role of DPT in children with unpredictable ADRs, and compare the causative drugs and clinical characteristics between detailed history of ADRs and result of DPTs. Methods: We included 16 children who were experienced ADRs referred to pediatric allergy clinic at Ajou University Hospital (January 2006 to December 2009). With various suspected drugs, 71 DPTs were done in 16 patients using our own protocol, and skin tests to antibiotics were combined in ADRs to antibiotics in medical history. Results: There were 17 (23.9%) positive DPTs results out of 71 individual DPTs, and 11 patients (68.8%) from 16 patients were positive to at least one drug. Drugs causing positive reactions were acetaminophen in 5 (31%), Non-steroidal anti-inflammatory drugs in 4 (25%), penicillin in 3 (19%), cephalosporin in 2 (13%), and cotrimoxazole, macrolide and lactose in 1 each. Conclusion: DPT seems a safe and useful procedure to confirm causative drug and identify safely administering alternative drugs in children with ADR.

Low back pain is a common clinical condition with heterogeneous causes and challenges to manage. High prevalence and numerous assessments result in an enormous socioeconomic burden. Clinician must conduct efficient and stepwise evaluation process to rule out serious spinal pathology, neurologic involvement, and identify risk factors for chronicity. The process can be achieved through the focused history taking and physical examination. Certain factors related to serious spinal pathology include age (>50 years), trauma, unexplained fever, recent urinary or skin infection, unrelenting night or rest pain, unexplained weight loss, osteoporosis, immunosuppression, steroid use, and widespread neurological symptoms. In non-specific low back pain, diagnostic imaging and laboratory studies are often unnecessary and can disturb an appropriate management. For the management of acute low back pain, patient education and medication such as acetaminophen, non-steroidal anti-inflammatory drugs, and muscle relaxants are recommended. For chronic low back pain, behavior therapy, back exercise, and spinal manipulation are beneficial. The evidence based approach could improve success rate of management, result in prevention of acute low back pain from being chronic intractable pain.

Purpose: On November 15, 2012, sales of OTC (Over-The-Counter) drugs began at convenience stores, which changed the accessibility of some drugs. As a result, the exposure and access patterns of these drugs could have changed. In this study, we reviewed the changes in the characteristics of drug poisoning patients because of the reposition of nonprescription drugs according to the revised Pharmaceutical Affairs Act. Methods: A retrospective study was conducted to evaluate changes in characteristics of drug poisoning patients between 2008 and 2016. A registry was developed by an emergency medical center in a local tertiary teaching hospital, and patients who visited the center were enrolled in this registry. We compared two periods, from 2008 to 2012 (Pre OTC) and from 2013 to 2016 (Post OTC), for type of intoxicant, time from poisoning to visiting the emergency center, intention, psychiatric history, previous suicidal attempt, alcohol status, and emergency room outcomes. The primary outcome was the number of patients who took acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Secondary outcomes were ICU admission rate, mortality rate, and number of patients who visited the ER when the pharmacy was closed after taking acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Results: Among 1,564 patients, 945 and 619 patients visited the emergency room during pre and post OTC periods. The number of patients with acetaminophen and NSAIDs poisoning decreased from 9.2% to 6.1% (p=0.016). The ICU admission rate and mortality rate in the emergency room did not show significant results in the relevant patient groups, and so was the number of patients visiting ER when the pharmacy was closed taking acetaminophen and NSAIDs. Conclusion: Despite the sales of nonprescription drugs at convenience stores, the number of acetaminophen and NSAIDs poisoning patients decreased.

Over 30 million prescriptions of NSAIDs (non-steroidal anti-inflammatory drugs) are issued every year. Considering that these drugs are available without a prescription as over the counter (OTC) drugs, their use will be astronomical. With the increasing use of NSAIDs, their adverse effects are drawing attention. Especially, stomach bleeding, kidney toxicity, liver toxicity, and neurological toxicity are reported as common. Ibuprofen, one of the extensively used NSAIDs along with aspirin, can also induce liver toxicity, but few studies are addressing this point. Here we examined the liver toxicity of ibuprofen and investigated whether co-exposure to ethanol can manifest synergistic effects. We employed 2D and 3D cultured human hepatoma cells, HepG2 to examine the synergistic hepatotoxicity of ibuprofen and alcohol concerning cell viability, morphology, and histology of 3D spheroids. As a result, ibuprofen and alcohol provoked synergistic hepatotoxicity against hepatocytes, and their toxicity increased prominently in 3D culture upon extended exposure. Oxidative stress appeared to be the mechanisms underlying the synergistic toxicity of ibuprofen and alcohol as evidenced by increased production of ROS and expression of the endogenous antioxidant system. Collectively, this study has demonstrated that ibuprofen and EtOH can induce synergistic hepatotoxicity, providing a line of evidence for caution against the use of ibuprofen in combination with alcohol.
