Objective: Generic drugs similar in appearance to their brand-name counterparts have both advantages and disadvantages. This study aimed to investigate patient preferences regarding the appearance of generic drugs.
Design: A cross-sectional survey.
Methods: We conducted a web-based survey between 2013 and 2014. Patients aged ≥40 years who reported taking prescription drugs for >6 months were asked to provide their opinions on the appearance of generic drug formulations and press-through packages (PTPs). Medical doctors and pharmacists were asked as to what type of appearance of generic drugs would be suitable as well as whether the appearance of these drugs and PTPs should be similar to that of their brand-name counterparts.
Results: A total of 911 patients, 238 pharmacists, and 81 medical doctors responded to the survey. Most of the patients (45.3%) surveyed reported that the similarity in the appearance of generic drug formulations and PTPs to those of their brand-name counterparts was not important, whereas only 15.6% of patients preferred generic drug formulations and PTPs similar in appearance to their brand-name counterparts. In contrast, most of the medical doctors (53.1%) and pharmacists (88.2%) reported that the appearance of generic drug formulations and PTPs should be similar to that of their brand-name counterparts.
Conclusion: Patients’ opinions on the appearance of generic drugs differ from what medical doctors and pharmacists perceive them to be. Therefore, health care professionals should select generic drugs with an appearance as per the individual patient’s preference.

Objective: A perception survey of healthcare providers and pharmaceutical industries about the current package insert (PI) was conducted to evaluate whether its layout and issues such as the contents concerning drug-drug interactions are found appropriate.
Methods: A questionnaire was sent via the Internet to physicians of various subspecialties, or via the postal service to pharmacy-employed pharmacists and pharmaceutical industries. It consisted of questions regarding the PI layout, the information contents on drug-drug interactions and other matters about PI revision.
Results: The survey showed that the PI is a major source of drug information for physicians (82.4%) and pharmacists (98.7%). The layout (order of appearance of headings and information about drug interactions in a tabular format) of the current PI is widely accepted by physicians, pharmacists, and pharmaceutical industries. There was, however, some degree of disagreement within these three groups in the perceptions about the presentation/contents of the several drug interactions, as well as about the timing for its updating. Around 24% of physicians and 35% of pharmacists view that the content of drug interactions is insufficient, and that information about adverse drug reactions and drug interactions is not enough updated in the PIs. On the other hand, near 86% of pharmaceutical industries were prone to wait for accumulation of enough data until revising the information in PIs.
Conclusions: Differences of perception were found between healthcare providers (i.e., PI users) and industries. Our survey revealed that the basic layout of the current PI should be preserved, but there are issues such as the contents and updating of information regarding drug interactions and adverse drug interactions that may require modifications according to the healthcare providers’ point of view.

Objective: Prescription check and inquiry is one of the most important operations of pharmacists to provide optimal drug therapy to the patient. Although a number of studies related to inquiries of prescriptions have already been reported, there is little report about requests for doctor and hospital based on the examples. Therefore, this study aimed to clarify the current problems revealed by inquiries about prescriptions by not only analyzing these inquiries but also investigating requests for doctors and hospitals.
Methods: We investigated 6,255 inquiries about prescriptions and requests for doctors and hospitals at 584 insurance pharmacies from August 4 to 10, 2014. Then, the inquiries about prescriptions and requests for doctors and hospitals were categorized.
Results: The most frequent category of inquiries about prescriptions was “Questions about administration and dosage” (21.5%). On the contrary, the most frequent request for doctors was “Efficiency in gathering information from and providing information to a patient” (2,067 cases).
Conclusions: The present study clarified current problems revealed by inquiries about prescriptions by investigating requests for doctors and hospitals that were based on examples. Furthermore, the problems were classified into ten categories, and these should be noted by doctors and hospitals at the time the prescription was issued.
4.In intro delivery of gene encoding neurotrophic (GDNF) into brain by gene transfer.
Acta Pharmaceutica Sinica 2005;40(1):87-90
AIMThe gene encoding neurotrophic factor was transfected into brain capillary endothelial cells with the aim of delivering the gene product extensively into the brain parenchyma by making use of the secretory function of BCECs.
METHODSPlasmid DNA encoding mouse glial cell-derived neurotrophic factor (mGDNF gene) was constructed and prepared. Then, mGDNF gene was transfected into cultured mouse brain capillary endothelial cells (BCECs) in vitro. The amount of mGDNF protein in the transfected cells and secreted from the transfected cells were determined by ELISA. The polarity of the secretion of mGDNF protein from BCECs was investigated in a bicameral culture system.
RESULTSThe mGDNF protein was detected out not only from the transfected cells but also the cultured media. And mGDNF protein was mainly found in the brain side of the culture compartment.
CONCLUSIONIt has been demonstrated that a secretory protein can be successfully delivered into brain parenchyma by utilizing the secretory pathway of BCECs.

Objective: The revised Pharmaceutical Affairs Act that came into force in June 2009 prohibits the sale of nonprescription drugs via mail. However, as a provisional measure, regular users and inhabitants of remote islands who do not have access to pharmacies or drug stores are allowed to purchase nonprescription drugs via mail until the end of May 2013. This study involves a survey on the purchasing of nonprescription drugs by Internet-illiterate inhabitants of the remote Goto Islands, Nagasaki Prefecture, Japan.
Methods: Our process began with the distribution of questionnaires via mail to inhabitants of the remote Goto Islands, of whom 3,819 were randomly selected. The responses were sent between January 22 and February 26, 2011. We analyzed problems presented by 522 inhabitants who were Internet-illiterate.
Results: The results revealed that 57.3% of the respondents living on large islands—with pharmacies, drug stores, and pharmacists— (e.g., Fukueshima) and 85.3% of respondents living on small islands scattered around large islands—with none of the abovementioned amenities— (e.g., Maeshima) were Internet-illiterate. Additionally, a majority of the respondents (more than 80%) felt no need to purchase nonprescription drugs over the Internet. However, considering that a handful of these inhabitants do, or will at some time need to purchase nonprescription drugs over the Internet, we strive to establish an optimal system for supplying medications to these Internet-illiterate inhabitants.
Conclusion: Community pharmacists need to establish close relationships with the Internet illiterate (particularly those living on small islands) and promote the overall appropriate use of medicinal products.

Objectives: First steps to promote the proper use of medicines in remote islands and rural areas are as follows: (1) recognition of the profession of “pharmacist” from secondary-remote-island residents who do not have a pharmacy or drugstore or the opportunity for pharmacist contact and (2) an understanding by remote-island residents of the advantages of having a “family pharmacist.”
Methods: Repeated “medicine information and consultation sessions” for secondary-remote-island residents of Japan’s Nagasaki Prefecture were held. Residents were then surveyed for changes in awareness of or demand for pharmacists and the nature of such changes.
Results: Before the information sessions, 29.7% of residents did not recognize the profession of pharmacy, but the extent of their recognition increased after information sessions were concluded. They were asked “Who explains medicines in a way that is easy to understand ?”; more than half responded “doctors” before the information session, but after information sessions were concluded, those who said “pharmacists” increased.
Conclusion: Conducting “medicine information and consultation sessions” for residents of secondary-remote islands and rural areas enabled them to understand the profession of pharmacy. The initiatives in the present study are first steps toward promoting proper use of medicines by residents of remote islands and rural areas who use “family pharmacies/pharmacists.”

Objective: To compare effects of the fluoropyrimidines S-1 and capecitabine on prothrombin time international normalized ratios (PT-INR) of warfarin following coadministration and after discontinuation of each fluoropyrimidine treatment.
Methods: Medical records of patients receiving warfarin with either S-1 (6 patients) or capecitabine (7 patients) were obtained from four hospitals.
Results: Increased PT-INR was observed until peak levels of warfarin were achieved in all patients in S-1 and capecitabine treatment groups. Moreover, PT-INR significantly changed after coadministration within each group (p<0.05). Specifically, ratios of peak PT-INR after coadministration of each fluoropyrimidine and those following administration of warfarin alone (PT-INR elevation ratio) were 3.31 and 3.29 in S-1 and capecitabine coadministration groups, respectively. Moreover, numbers of days to peak PT-INR were 38.3 and 31.3 days, respectively, and did not significantly differ between the treatment groups. Furthermore, PT-INR returned to pretreatment levels by 17.5 and 15.1 days after discontinuation of S-1 and capecitabine, respectively, and did not significantly differ between the treatment groups.
Conclusion: Coadministration of S-1 and capecitabine similarly prolongs PT-INR by approximately 3-fold compared with administration of warfarin alone; therefore, these drug-drug interactions were clinically suggested to be of high risk for episodes of bleeding and remarkable alterations in coagulation parameters. Therefore, blood coagulation ability should be more carefully monitored with regard to PT-INRs in patients receiving warfarin with S-1 or capecitabine not only during coadministration but also after discontinuation of fluoropyrimidine treatments.

The Association of Radiologists under the umbrella of the Hokkaido Prefectural Federation of Agricultural Cooperatives for Health and Welfare (Hokkaido Koseiren) set up in 2003 a committee with the aim of improving the accuracy of mass health examinations. Recently, the committee reviewed the results of abdominal examinations by sonography performed at the eight hospitals affiliated with the Koseiren during fiscal 2006 that ended March 31, 2007. Of those individuals who underwent thorough health checkups, 91.3% had their abdomen examined by ultrasound. Something anomalous was detected in 68.1% of the examinees and 4.5% needed to undergo closer checkups, the rate of response to which was 74.5%. The detection ratio of cancer by ultrasonography was worked out at 0.048%. The ratio of patients requiring a closer exam to the total and the cancer detection ratio varied widely from hospital to hospital. The wide dispersion was ascribable to the difference in the standard of judgment for indicating closer examinations and the difference in the number of examinees so far as the cancer detection ratio was concerned, from hospital to hospital. A look at the primary findings of anomalies revealed that fatty liver topped the list accounting for 27.4% followed by cholelithiasis with 3.6%. From this, we realized that the abdominal examinations by sonography served to detect cancer and lifestyle-induced health problems as well. Organ-wise, the cancer cases found during the period from 1998 to 2009 broke down as follows: kidney (79 cases), liver (40 cases), pancreas (30 cases), gall bladder (24 cases), others (8 cases) and spleen (none). The cancer detection ratio per year ranged from 0.03 to 0.05% during the period.

Anxiety and difficulty in administering medication to nursery school children has been reported among nursery school teachers. This study aimed to elucidate these issues and explore the possibility of pharmacist support and collaboration. We conducted a postal survey in September 2019 among nursery schools in Tokyo that are categorized as government-authorized schools, certified childcare centers, and prefectural governor-certified schools. A total of 1,537 schools responded to the self-report questionnaires (response rate: 41.2%), and 1,533 responses were analyzed. Of these, 1,488 schools were asked if they would accept requests to administer medication to their school children, and 60.1% of the nursery schools responded that their staff (including teachers and nurses) found it difficult to administer medication. The issues identified included psychological burdens (such as nervousness and pressure about giving the correct medication), staff shortage, insufficient time with the children, and human factors (such as personal perceptions of medication). Additionally, excessive requests to administer medication, caregiver behavior such as low awareness of children’s health and appropriate medication, and poor medication adherence at home were identified as issues. It was suggested that pharmacists could help alleviate these problems through their daily work at the pharmacy. Approximately 49-62% of schools responded that they would request the collaboration of community pharmacists to conduct training sessions for nursery school staff, provide health support for caregivers, and provide general health and medication consultations. The collaboration between nursery schools and community pharmacists may gain importance in the future.

In 2008, Japanese Society of Drug Informatics (JASDI) organized the Future Vision Committee (the Committee) to propose the essential focus of drug informatics. To explore a future vision about the drug information sciences, it was necessary to collect a variety of opinions widely from researchers. Therefore, at the 11th annual meeting of JASDI in July 5-6, 2008, the Committee convened a workshop to extract problems in the researches of drug informatics by using KJ method and evaluated the contents. The major problems raised were “the field of drug informatics is too broad” and “there is no definition and/or no system of the drug informatics”. Related problems raised are the shortness of the history and lack of originality in the study. From different viewpoints, it was also pointed out that the methodology of the research is not well established and no systematic education is provided. Taken together, major problems in drug informatics are concluded to be the lack of definition and the lack of systematizations, and will be solved to a certain extent by defining the outcome of the researches in drug informatics.
