    Objective: The purpose of this study is to compare the clinical efficacy between original drugs and generic products.  Candidate drugs included two types of hydroxymethylglutaryl-CoA (HMG-CoA) reductase inhibitors, simvastatin and pravastatin, because of their importance at reducing the health expenditure for hyperlipidemia.
    Design: We retrospectively evaluated the efficacy (total cholesterol, triglyceride, low-density lipoprotein and high-density lipoprotein levels), safety (biochemical parameters), and medication adherence based on patient data.  We set the follow-up period at 6 months before and after substitution.  Data were analyzed by paired-sample t-tests (statistical significance level of 0.05).
    Methods: The subjects included in this study were ambulatory patients visiting Nakajima Hospital for dyslipidemia treatment.  Selected patients included those taking both the original drug and the generic product; i.e., patients who had substituted the original drug Lipovas® for the generic product Simvastatin OHARA, or those who had substituted the original drug Mevalotin® for the generic drug Pravatin®.
    Results: A total of 118 patients in the simvastatin study and 43 patients in the pravastatin study were candidates for the present study.  We found that there were no significant differences before and after substitution.  Even though there were differences in some of the biochemical parameters, the range remained within normal levels.  With regard to medication adherence, we found no significant differences.
    Conclusion: In this study, we found no significant differences before and after substituting medications with generic drugs.  Additionally, we found no subjective symptom changes after substitution.  To develop clinical information on generic products and to store such information, it is important that pharmaceutical products be used appropriately.

    Objective: Drug information literacy is necessary for pharmacists.  This study investigated the effect of practical training on the drug information literacy of pharmacy students.
    Methods: We conducted practical training in the drug information room of hospital pharmacy.  Then we asked the students two questions before and after the training.  We scored the drug information responses of students using four-point rating scales based on objective criteria.  We compared the scores obtained before and after training.  In addition, we researched the realization of several secondary and tertiary sources using a visual analog scale (VAS).  We then compared VAS findings before and after the training.
    Results: The score for drug information responses was significantly improved.  For sources other than MEDLINE (Pub Med), the VAS score also improved.  The students were aware of the information on package inserts before training.  There was significant improvement in awareness of books about pregnancy and lactation (e.g. Drugs in Pregnancy and Lactation) after training.  However, there were significant individual differences in awareness of MEDLINE, Up To Date, and the Cochrane Library.
    Conclusion: This practical training experience improved the drug information literacy of pharmacy students.  Before training, there were significant deficiencies in the process of literature search.  Therefore, this training was effective for advancement in drug information literacy of pharmacy students.

    Objective: It is very important that, to avoid, pharmacists-check medication being taken by patient.  In the Hokkaido University Hospital we used commercial drug identification software at the start of outpatient prescription identification duty and reported the outcome.  Furthermore, we filled in another hand-written check sheet with the drug’s name, whether or not it is used in our hospital, alternative drugs, and the dosage and administration.  Because of the risk of drugs being entered by mistake, we built a database for drug identification and distinguished the outpatient’s prescriptions.  With this system it is possible integrate identification reports and check sheet using one style, automatically.  We also to smoothly rationalize duties by planning correct communication between the medical staff.  At the same time, we analyzed the case that was able to intervene in reasonable use of medical supplies with a past identification report as a result of pharmacists distinguishing outpatient prescriptions.
    Design and Methods: This system was constructed using Microsoft® Access, which is a general-purpose database software.  Also, the medical supply database that we used for this system uses “Drugs in Japan Ethical Drugs DB (supervised by Drugs in Japan Forum)” published by JIHO Co., Ltd.
    Results: By using this system, we were able to reduce the time required to identify the drugs and make the report.  The result of a questionnaire carried out on doctors and a nurses and medical staff revealed that more than 90% of the respondents claimed, “the report is easy to refer.”  Likewise, we analyzed a report of the previous year and recognized that medical staff could not find the inappropriate use of prescriptions for outpatients in about 17.5%.
    Conclusion: This system improved the efficiency of outpatient prescriptions practices, and it became clear that it could be used convincingly as a tool to share appropriate drug information between medical staff and pharmacists, more precisely.  In addition, feedback from medical staff suggested that it might prevent the risk of problems surrounding outpatient prescriptions, from the viewpoint of the pharmacist.

    Objective: In recent years, the Ministry of Health, Labor and Welfare has actively promoted the use of generic drugs.  However, implementation of this policy has not progressed smoothly, as information on generic drugs is poorly organized.  As a result, it is difficult for pharmacists to select the appropriate generic drugs.  Therefore, we attempted to develop a code system to organize information on generic drugs.
    Methods: We analyzed the guidelines used for the approval of generic drugs.  We then identified the important aspects for comparison of generic drugs and developed a code system.  Next, we tested this code system using temocapril hydrochloride tablets, which is a generic drug.
    Results: We were able to develop a code system for selection of generic drugs.  Furthermore, we confirmed the utility of this code system for selecting generic drugs in the case of temocapril hydrochloride tablets.
    Conclusion: We believe that this code system with be useful for pharmacists, but further development is necessary for other generic drugs.

    Objective: To clarify the relationship between the awareness of pharmacists regarding instructions on the use of inhaled corticosteroids and the instructions conveyed.
    Design: Fact-finding-survey using self-administered questionnaires.
    Methods: The survey items consisted of age, years of clinical experience, number of prescriptions from asthmatics per month (“number of prescriptions”), items to concern when giving instructions (“items to concern”) time required to give instructions on inhaler usage (“time required”), and the pharmacists’ awareness regarding instructions on the inhaler usage (“awareness items”).  There were six awareness items for which responses were solicited on a four-grade scale.  Respondents were divided into two groups: a “high awareness” group giving responses of “completely agree” (or “completely disagree” for diametrically opposed items) and a “low awareness” group giving other responses.  T test was used to compare the average of age, years of clinical experience, number of prescriptions, concern degree, and time required between 2 groups.
    Results: This showed the higher consciousness that “instructions on inhaler usage are important issue relating to the patient’s asthma therapy” was significantly-high degree of concern and time required.  Also, the consciousness that “instructions on inhaler usage are a specialized activity performed by pharmacists” was related to age, years of clinical experience and level of concern degree.  Additionally, this suggested the pharmacists giving negative responses with respect to the notions that “the effect of instructions on inhaler usage is not worth the trouble” and “patients have insufficient desire to master of inhaler usage” had a higher degree of concern.
    Conclusions: For significance and importance of instructions on inhaler usage, there was confirmed to be relationship between pharmacists’ awareness and the information conveyed and time spent on the instructions.  This suggested that it was important to improve awareness of instructions on inhaler usage in both the clinical and educational setting.
