Objective: The clinical literature review is an important and required components in most of the US pharmacy school curriculum.  On the other hand, in Japan, pharmacy students usually read basic literature when research assignments are given.  However, in Japan, one is rarely taught how to critically read clinical literature in class.  Therefore, for the purpose of examining whether or not lectures regarding how to critically read clinical literature will affect collecting new drug information in pharmacy practice, we examined a survey which we circulated in both countries.  The survey asks pharmacists about reading clinical literature.Methods: One thousand nine hundred and ninety-seven pharmacists in Miyagi in Japan were given questionnaires by mail and 18,744 pharmacists in Florida in the US were given the URL of a web questionnaire by email.Results: Response rates in Miyagi and Florida were 30.3% and 0.91%, respectively.  Since the response in Florida was so small, statistical analysis was not performed.  Regarding the question of “Do you HABITUALLY read clinical literature ?,” “Yes” in Miyagi and Florida was 14.7% and 71.9%, respectively.  Regarding the question of “To what extent did you learn how to critically read clinical literature when you were a student-pharmacist ? ” (1: Not at all, 7: Yes), medians in Miyagi and Florida were “1” and “5,” respectively.  Regarding the question of “To what extent do you apply the information you obtain from clinical literature to your daily responsibilities ? ” (1: Not at all, 7: Yes), medians in Miyagi and Florida were “2” and “5,” respectively.Conclusions: We conclude that Japanese pharmacists in clinical practice do not sufficiently utilize drug information from new clinical literature because pharmacy education in Japan did not, until very recently at least, teach how to critically read clinical literature in class.

Objective: We analyzed the effects of the number of prescriptions on the number of drug stocks in community pharmacies by administering questionnaires to community pharmacies in Shiga Prefecture, Japan (N=159).Methords: We identified a significant positive correlation between drug stocks and their amount, and a significant negative correlation between inventory turnover and the concentration ratio of prescriptions issued by any medical institutions.  Therefore, this implies that the amount of drug stocks influenced value, and a lower ratio of prescriptions issued by neighboring medical institutions increased inventory turnover.  Furthermore, multi-regression analyses on the amount of drug stocks and the number of prescriptions from neighboring medical institutions and other medical institutions were performed.  The results are as follows.Results: The number of stock drugs is much less influenced by the number of the prescription of vicinity medical institutions than the other medical institutions.  On the other hands, the money amount of stock is more influenced by the number of the prescription of vicinity medical institutions than the other medical institutions.Conclusions: We thus identified the relation between the number of prescriptions from neighboring or other medical institutions and the number of drug stocks and their amount.  These findings will be made available to community pharmacies that want to prescriptions issued by not only the neighboring medical institutions but others as well.

Objective: If product information provided by pharmaceutical manufactures is not consistent with a product assessment made by the Pharmaceuticals and Medical Devices Agency (PMDA), users may gain false perceptions about the product, which may be detrimental to patients.  An investigation was conducted to compare the contents of product information provided by pharmaceutical manufacturers and product evaluation reports prepared by PMDA to identify any discrepancies between data assessment in the two documents.Methods: Descriptions in “Product Characteristics” and “Clinical Studies” of product information summaries were compared with product evaluation reports prepared by PMDA.  Inquiries were addressed to manufacturers if any questions arose.Results: The investigation was conducted on 66 new active ingredients approved in 2009 to 2010.  As 14 questions arose with 12 ingredients, inquiries were addressed to manufacturers, all of whom offered a response.  As a result, four questions were resolved for two ingredients.  However, for the remaining products, it was revealed that the manufacturers described in the product information summaries what they claimed at the time of submission even though their claims were not accepted by PMDA.Conclusion: It was considered that the pharmaceutical manufacturers possibly did not comprehend the contents of the PMDA’s evaluation reports.  It was suggested that the industry as a whole should examine the issue.  As discrepancies were observed even in product information summaries, which are viewed by a relatively large number of people, it was assumed that more issues may be found in promotional materials provided exclusively to healthcare professionals.

Objective: To clarify the background difference between drug-induced photosensitivity and ultraviolet-visible absorption spectrum or structure and to construct useful information for prevention and prediction of drug-induced photosensitivity. Methods: We investigated whether, for 457 drugs for which the ultraviolet-visible absorption spectrum is listed in the Japanese Pharmacopoeia, there were absorption maxima in the UVA (320 nm or more and less than 400 nm), UVB (280 nm or more and less than 320 nm), or UVA and UVB (280 nm or more and less than 400 nm). Structure was investigated for the existence of “conjugated”, carbonyl, sulfone, nitro and fluorine. The case drug group was taken to be those drugs for which photosensitivity was listed as a side effect on the medical drug package insert. Using statistical software, SPSS statistics ® 24 (IBM), we performed univariate logistic regression analysis, and multivariate logistic regression analysis with a stepwise increment method (likelihood ratio) combining items with p<0.2, and calculated the odds ratio (hereinafter: aOR). The significance level was taken as 0.05.Results: There were 85 drugs in the case drug group, and 372 drugs in the control drug group. As a result of multiple logistic regression analysis, in Model 1, we placed sulfone (aOR: 4.55, 95% C.I.: 2.22-9.35), fluorine (aOR: 3.66, 95% C.I.: 1.82-7.39) and nitro (aOR: 4.46, 95 % C.I.: 1.73-11.48) in this order. In Model 2, we placed sulfone (aOR: 4, 40, 95% C.I.: 2.12-9.15), fluorine (aOR: 3.81, 95% C.I.: 1.87-7.76), UVA (aOR: 2.40, 95% C.I.: 1.37-4.18) and nitro (aOR: 3.61, 95% C.I.: 1.39-9.40) in this order.Conclusion: When a drug is developed, its ultraviolet-visible absorption spectra and structure become clear, and from this information,measures can be taken which bear the potential risk of photosensitivity in mind.

Objective:In this study,we explored adverse reactions and patient background and performed a case/non-case study on a database of adverse reaction case reports in order aid the prevention of non-prescription drug abuse.Study Design:We conducted a case/non-case study on a database of adverse reaction case reports.Methods:We studied case reports of adverse reactions and addiction in Japan and extracted adverse reaction cases associated with taking antipyretic analgesics,antitussive drugs,antitussive expectorant drugs,hypnotic and sedative drugs,anti-anxiety drugs,and purgative drugs. We divided the extracted cases into an abuse case group (adverse reactions associated with non-prescription drug abuse,and divided its intended purpose or the purpose of abuse at the initial dose)and non-case group(other adverse reactions). We performed univariate logistic regression analysis on each item of investigation in the abuse case group and non-case group and calculated the odds ratio,p-value,and 95%confidence interval.Results:There were many abuse case reports of women 20-40 years old in the antipyretic analgesics abuse case group and many of them had liver/biliary lesions and chronic urological impairment. The most common reason reported for taking the initial dose of each drug was for its intended purpose.Discussion:It is important for pharmacists at community pharmacies and drugstores to be able to recognize the characteristics of patients who might be at risk of abuse and the adverse reactions and patient backgrounds elucidated in this study could be helpful in identifying them.

Objective: For effective use of over-the-counter (OTC) drugs that are provided as relief supplies during a disaster, we aimed to develop a list of OTC drugs that can be used during a disaster.Methods: We obtained information about OTC drugs useful during a disaster by examining results of previous studies and lists of drugs used during a disaster.  We analyzed this information with the expert pharmacist of disaster support and established a rationale for our list and developed “the List of Useful OTC Drugs During a Disaster” and “the Information Card on Useful OTC Drugs During a Disaster.”Results: We developed our list of OTC drugs based on the following parameters: (1) while people with severe disorders (e.g. renal failure) are treated by medical teams, those with minor physical conditions are treated using OTC drugs and (2) those OTC drugs that can be used as substitutes for prescription drugs were preferably selected.  The List of Useful OTC Drugs ()—During a Disaster (containing 56 items) was developed for use mainly by medical professionals.  Further, pharmacists from disaster-relief medical teams may not always be available in disaster-stricken areas; therefore, the Information Card on Useful OTC Drugs During a Disaster was developed to enable disaster victims to independently make a certain level of decision.  The information card contained pictograms to call the attention of the disaster victims.Conclusion: Our results can provide a common tool for drug suppliers, medical professionals engaging in relief works in disaster-stricken areas, and disaster victims.

Objective: A simple suspension method in our previous study indicated that the amount of amlodipine recovered from a Norvasc®OD tablet was decreased by simultaneous suspension of a Magmitt®tablet containing magnesium oxide, due to the increase in pH.  However, it is still unclear whether this incompatibility arises in both brand name and generic tablets because the tablets may have different additives and mechanical properties.  In this study, we evaluated the degree of incompatibility between Magmitt®tablets and a range of amlodipine besylate tablets, including original and generic versions.Methods: Twenty-four kinds of amlodipine besylate tablets were used.  Magmitt®and amlodipine besylate tablets were suspended in warm water (55°C), and 10 min or 2 h later, the amount of amlodipine in the suspension was measured by HPLC-UV.Results: For almost all tested tablets, the recovery amount of amlodipine was significantly decreased in the presence of Magmitt®, and the amount recovered varied significantly between the types of amlodipine tablets.  However, Magmitt®tablet had little effect on the recovery of amlodipine from two specific brand tablets.Conclusions: An incompatibility between Magmitt®and most types of amlodipine besylate could be observed, although the degree of incompatibility depended on the brand of amlodipine.  These results are useful for the proper use of drugs.

Objective: Finger-tip unit (FTU) has been used in Western countries to apply a specific amount of steroid ointment available in tube form.  Although prescription ointments for treating skin disorders are available in Japan, there are no indications for patients regarding the amount to be used.  Therefore, we investigated the factual assessment of patient compliance instructions on using the ointments given by pharmacists and conducted a comparative test on the amount of ointment in 1 FTU using commercially available ointment tube products.Methods: We conducted a questionnaire survey for 21 hospital pharmacists on patient compliance instructions for ointments.  Using six types of ointments, we measured the aperture area of ointment tube, weight of 1 FTU and squeezing number of tube.Results: Fewer than 50% of pharmacists explained the application methods and amounts for one-time use when they provided patient compliance instructions.  There were many patients who used an ointment inadequately.  The most were problems about the quantity of application.  Wide variations were found among the amount of ointment in 1 FTU weight and number of available uses.Conclusion: The survey results demonstrated that the methods used to apply the ointments are items that must also be emphasized by pharmacists when providing patients compliance instructions.  Furthermore, the patient compliance instructions should include the amount of ointment in 1 FTU and number of available uses within pharmaceutical products.

Objective: Taking the wrong medicine or medication error is a serious concern to patient safety.  The aim of this study was to statistically survey the relation between the placement of drugs on medicine shelf and the occurrence of error in taking a medicine.Methods: The study comprised 2 groups.  The incident group contained 43 cases that were erroneously taken in the Obihiro Kosei General Hospital.  The control group contained 43 drug pairs matched by the similarity index of the drug names from among the drugs used in the hospital at random.  The similarity index of drug names was based on 10 quantitative indicators.  The distance of medicine shelf arrangement was represented by three variables: the horizontal distance, the vertical distance and the distance of shelf block.  Conditional logistic regression analyses of the occurrence of medication errors were performed by evaluating the three variables of the distance factor and their interaction for error in taking a similar-sounding named drugs.Results: Conditional logistic regression analysis revealed that the vertical distance (OR: 0.64, 95%CI: 0.42-0.99) and the distance of the shelf block (OR: 0.74, 95%CI: 0.57-0.97) were significant risk-reduction factors of medication errors.  Four variables were extracted as the most suitable logistic regression model in terms of the interaction between them.  As the interaction between 3 variables (the horizontal distance, the vertical distance and the distance of shelf block) was significant (OR: 0.93, 95%CI: 0.86-0.99), they may be considered as synergistic risk-reduction factors.  Moreover, the horizontal distance was found to be a risk-enhancement factor (OR: 1.52, 95%CI: 0.93-2.48).Discussion: In order to reduce the risk of medication errors due to similar-sounding drug names, placement of drug on the medicine shelf should take into consideration the three coordinates of the distance factor.

Objective: Although generic drugs are considered bioequivalent to the original drugs, for formulations such as adhesive agents, the sensation during use (hereinafter, “sensation”) and handling characteristics (hereinafter, “handling”) are usually not investigated during the approval process.  Therefore, we established new drug evaluation criteria for transdermal adhesive agents, which included those relevant to handling and sensation, and investigated their usefulness.Methods: This study assessed four test samples: the original loxoprofen sodium 100 mg tape (hereinafter, “LX-P 100 mg”) and three generic versions considered economically acceptable by our hospital.  The formulations were evaluated based on our criteria for generic drugs.  The handling and sensation were evaluated using a questionnaire with six parameters related to sensation and seven parameters related to handling.  The enrolled subjects comprised 20 pharmacists from our hospital.  Furthermore, a parallel evaluation using loxoprofen sodium 50 mg tape (hereinafter, “LX-P 50 mg”) was performed to explore the variance in the results of each individual criterion.Results: The evaluation revealed differences between the formulations with regard to the thickness of the adhesive agent and stability after opening the package.  Various differences were observed by evaluation of the handling and sensation.  Based on the parameters used, the differences between the various formulations of LX-P 100 mg occurred in the following criteria: tactile sensation commensurate to the degree of adhesion; superficial resemblance to other agents; ease of adhesion; and ease of package opening.  For LX-P 50 mg, the differences were found in superficial resemblance to other agents and ease of liner removal.Conclusion: Our newly established criteria for the evaluation of LX-P 100 mg revealed differences between the samples, which were used to identify products with poor handling and sensation.  Thus, this study successfully demonstrated the usefulness of the criteria for the purpose of medicine selection.

Objective: The dispensing fee revision of April in 2016 made a review of the assessment of inquiries about prescriptions.  The requirement was added by articles that seemed to be pharmaceutically necessary, showing an increase of responsibility for pharmacists.  Based on this, we performed a discussion while collecting the cases of inquiries about prescriptions.Method: Among the inquiries about prescriptions performed at Jinjo Pharmacy for 4 months starting from April in 2016, we selected 83 cases where a prescription was changed by the pharmacist’s recommendation, based on pharmaceutical information such as drug duplication or drug interaction and confirmation of leftover medicine.  Then, we compared them with the study of inquiries about prescriptions performed by the Japan Pharmaceutical Association in 2015.Result/Consideration: Inquiries about dose were the leading content, followed by those about duplication with other drugs of same indications and appropriateness of dose considering the adjustment of number of days due to residual drug, which showed the importance of medicinal history and prescription records.  It is considered necessary to renew the contents of the prescription record properly, based on the information acquired, while at the same time changing the pharmaceutical history based on those records.  It is thought that an inquiry about prescriptions will be performed appropriately by making a judgment based on such information. In order to do that, updated knowledge about medicine and updated information about drugs is necessary.  In comparison of the two studies, both showed that the drug information on “safety” and “dose and dose regimen” accounted for a large part of inquiries.  Further consideration on them will be necessary.

Objective: We have used therapeutic drug monitoring (TDM) analysis software to set the initial dose of vancomycin in our hospital.  In contrast, the TDM guideline, in which the initial dose of vancomycin per body weight was set, was published in 2012.  We looked forward with utilizing the TDM guideline in the clinical setting, after which we conducted multiple surveys to determine the important points of the TDM guideline.Methods: We surveyed patients treated with vancomycin, in whom the initial dose was set using the TDM analysis software and the concordance rate between the vancomycin dose set with the software and that set with the TDM guideline.Results: The concordance rate of vancomycin dose was 42.1%.  The mean age of the high-dose group (vancomycin dose higher than that recommended by the TDM guideline), was younger than that of the recommended-dose group.  Additionally, the mean body weight of the high-dose group was significantly lower than that of the recommended-dose group.  The corrected creatinine clearance of the low-dose group was significantly lower than that of the recommended-dose group.Conclusion: Our results suggest that when the initial dose is set after referring the TDM guideline in patients who are not very high age, and having low body weight and decreased renal function, the dose may differ from the dose set by using TDM analysis software.  In addition, since the recommended dose per body weight is a range and not a single value, setting the dose appropriate to target trough concentration is necessary.

Objective: Celecoxib has been reported to enhance the action of warfarin by inhibiting CYP2C9, its major hepatic drug-metabolizing enzyme, but sufficient information about the mechanism has not been obtained, especially in Japan.Methods: A study was conducted to investigate the prothrombin time international normalized ratio (PT-INR) and the warfarin sensitivity index (WSI) before and after concurrent administration of celecoxib, as well as the Drug Interaction Probability Scale (DIPS) scores to determine causality with drug interactions, in patients commencing concurrent therapy with celecoxib and warfarin at Kanagawa Prefectural Keiyukai Keiyu Hospital during the 4-year period from October 2011 to September 2015.Results: Analysis of 18 patients showed that the PT-INR increased significantly from 1.53±0.43 before concurrent therapy to 2.18±1.01 after concurrent therapy (p=0.0101).  The WSI also increased significantly from 0.76±0.50 before concurrent therapy to 1.01±0.65 after concurrent therapy (p=0.0044).  According to the DIPS scores, the causal relation was not rated as “Highly Probable” in any of the patients, while it was considered to be “Probable” in 3 patients, “Possible” in 10 patients, and “Doubtful” in 5 patients.Conclusion: The findings of this study suggested that when celecoxib treatment is initiated in patients who are already taking warfarin, attention must be paid to changes of coagulation profile, especially in elderly patients.

Objective: An external training seminar was held for registered salesclerks of drugs to help them keep and improve their knowledge of drugs.  To promote self-medication and to enhance the content of training seminars, we collected data in the form of inquiries the clerks had received from customers and what information the clerks sought from drug companies.Methods: Our survey was conducted with 199 registered salesclerks of drugs at an external training seminar in Tokyo, Japan.Results: The main inquiries from customers to the registered salesclerks were “selection of an analgesic for headache” (83.8%), “selection of an analgesic for cramps” (62.3%), and “selection of an analgesic for toothache” (57.7%).  The main information that they sought from drug companies were “side effects,” “interaction between drugs,” “time of onset of action,” and “degree of effect of drugs.”Conclusions: To respond to the inquiries from customers, it was necessary to supply the clerks with knowledge of pharmacokinetics in the external training and to supply them with information on side effects, interaction between drugs, time of onset of action, and degree of effect of drugs on individual products from drug companies.  Additionally, this information and knowledge of drugs can be gained from not only the external training and drug companies but also from pharmacists they work with.  It was thought that continuing the external training seminars and input of information from drug companies led to levels similar to a pharmacist and the registered salesclerks contributed actively to promoting self-medication.
