Evidence-based medicine (EBM) can be defined as “the integration of the best research evidence with clinical expertise and a patient's unique values and circumstances”. However, even with the best research evidence, many uncertainties can make clinical decisions difficult. As the social requirement of respecting patient values and preferences has been increasingly recognized, shared decision making (SDM) and consensus development between patients and clinicians have attracted attention. SDM is a process by which patients and clinicians make decisions and arrive at a consensus through interactive conversations and communications. During the process of SDM, patients and clinicians share information with each other on the goals they hope to achieve and responsibilities in meeting those goals. From the clinician's standpoint, information regarding the benefits and risks of potential treatment options based on current evidence and professional experience is provided to patients. From the patient's standpoint, information on personal values, preferences, and social roles is provided to clinicians. SDM is a sort of “wisdom” in the context of making autonomous decisions in uncertain, difficult situations through interactions and cooperation between patients and clinicians. Joint development of EBM and SDM will help facilitate patient-clinician relationships and improve the quality of healthcare.

The efficacy and safety of linaclotide in elderly patients are poorly understood. Herein, we aimed to assess the efficacy and safety of linaclotide in elderly patients in real-world setting. We retrospectively enrolled consecutive patients who started linaclotide therapy at Sapporo Medical University Hospital from October 1, 2017 to December 31, 2019. The efficacy and safety of linaclotide were examined in relation to various factors, including age (<65 or ≥65 years) and dose (0.25 or 0.5 mg/d). Fifty-two patients were enrolled, 60% of whom were over 65 years old and 40% were female. Thirty-six patients received a linaclotide dose of 0.25 mg/d. The most common side effect was diarrhea, but there was no difference in the incidence of diarrhea between the elderly (64.5%) and non-elderly patients (42.9%, p=0.130). No significant difference was observed with respect to improvement in constipation in the elderly (83.9%) and non-elderly patients (71.4%, p=0.318). Additionally, the difference in efficacy of linaclotide in patients who received a reduced dose (80.6%) vs. those who received the recommended dose (75.0%) was not statistically significant (p=0.719). Multivariate analysis revealed that age, gender, and dose were not associated with diarrhea induced by linaclotide treatment. However, concurrent treatment with constipation-inducing medications [odds ratio (OR) 5.79, p=0.047] and linaclotide monotherapy (OR 11.1, p=0.040) were both risk factors contributing to diarrhea. Linaclotide is effective and safe for use in elderly patients. The incidence of diarrhea may increase when linaclotide is administered alone or concurrently used with medications that cause constipation.

Oxidative damage results in protein modification and is observed in numerous diseases. Human serum albumin (HSA), the most abundant protein in the plasma, exerts important antioxidant activities to prevent oxidative damage. This paper focuses on the characterization of chemical changes in HSA that are induced by oxidative damage, their relevance to human pathology, and the most recent advances in clinical applications. The antioxidant properties of HSA are largely dependent on Cys-34 and its contribution to the maintenance of intravascular homeostasis, including protecting the vascular endothelium under conditions related to oxidative stress. Recent studies have also evaluated the susceptibility of other important amino acid residues to exposure to free radicals. The findings suggest that a redox change in HSA is related to the oxidation of several amino acid residues by different oxidants. On the other hand, the ratio of the oxidized form to the normal form of albumin (HMA/HNA), which is a function of the redox states of Cys-34, could serve as a useful marker for evaluating systemic redox states, which would be useful for the evaluation of disease progression and therapeutic efficacy. This review provides new insights into our current understanding of the mechanism of HSA oxidation, based on in vitro and in vivo studies.

Hypoglycemia due to treatment with oral anti-hyperglycemic agents (OHAs) is a major clinical problem in patients with type 2 diabetes mellitus. The aim of the present study was to evaluate the risk of hypoglycemia due to OHA use by using the Japanese Adverse Drug Event Report (JADER) database. To this end, reports of hypoglycemia events included in the JADER database between 2004 and 2012 were analyzed by calculating the reporting odds ratio (OR). The Medical Dictionary for Regulatory Activities Preferred Terms was used to identify hypoglycemia; 254392 reports were found in the JADER database, of which 13269 were excluded because the age and sex of the patient were not reported. Finally, 241123 reports were analyzed. Among OHAs, sulfonylureas showed the highest adjusted OR (adjusted OR, 10.13; 95% confidence interval, 9.08-11.26). The adjusted ORs for meglitinides, biguanide, thiazolidinedione, alpha-glucosidase inhibitors, and dipeptidyl peptidase-4 inhibitors were significantly lower than that of sulfonylureas. The adjusted OR of meglitinides (3.17; 95% confidence interval, 2.23-4.36) was significantly higher than that of alpha-glucosidase inhibitors or thiazolidinedione. We observed no difference between the adjusted ORs for biguanide, thiazolidinedione, alpha-glucosidase inhibitors, and dipeptidyl peptidase-4 inhibitors. Data mining of the JADER database was useful for analyzing OHA-associated hypoglycemia events. The results of our study suggested a low risk of hypoglycemia associated with biguanide, thiazolidinedione, alpha-glucosidase inhibitors, and dipeptidyl peptidase-4 inhibitors in clinical practice.

A growing body of evidence indicates that extracellular ATP released or leaked from nonexcitable cells as well as neurons plays important roles in the regulation of neuronal and glial functions in the entire body through ATP receptors. ATP receptors (ionotropic P2X and metabotropic P2Y receptors) are the most abundant receptor families in living organisms. In the central nervous system, these receptors participate in the synaptic transmission and intercellular communications between neurons and glia. The glia cells are classified into three types: astrocytes; oligodendrocytes; and microglia. There are many reports that spinal microglia express ATP receptors (P2X4, P2X7, P2Y6, and P2Y12 receptors) that have very important roles. We reported that several molecules of microglia are activated after peripheral nerve injury in a neuropathic pain model. In particular, P2X4 receptors (P2X4Rs) expressed in microglia play a critical role in evoking neuropathic pain. P2X4Rs are upregulated in spinal microglia after nerve injury by several factors such as the CC chemokine receptor CCR2, fibronectin in the spinal cord, interferon regulatory factor (IRF) 8, and IRF5 expressed in microglia. The inhibition of P2X4R action suppresses the functions of microglia and neuropathic pain. These results indicate that overexpressing P2X4Rs on microglia are a central player in evoking neuropathic pain.

Exercise is generally considered to have health benefits for the body, although its beneficial mechanisms have not been fully elucidated. Recent progressive research suggests that myokines, bioactive substances secreted from skeletal muscle, play an important role in mediating the benefits of exercise. There are three types of myokines in terms of the muscular secretion mechanism: those in which the secretion is promoted by stimulation, such as irisin, interleukin (IL)-6, and IL-15; those whose secretion is constitutive, such as thioredoxin, glutaredoxin, and peroxiredoxin; and those whose secretion is suppressed by stimulation, such as by a macrophage migration inhibitory factor. Although dozens of myokines have been reported, their physiological roles are not well understood. Therefore, there currently exists no advanced drug discovery research specifically targeting myokines, with the exception of Myostatin. Myostatin was discovered as a negative regulator of muscle growth. Myostatin is secreted from muscle cells as a myokine; it signals via an activin type IIB receptor in an autocrine manner, and regulates gene expressions involved in myogenesis. Given the studies to date that have been conducted on the utilization of myostatin inhibitors for the treatment of muscle weakness, including cachexia and sarcopenia, other myokines may also be new potential drug targets.

The area of radiation exposure by the nuclear accident occurred at Tokai village in 1999 was estimated by the ESR measurement of 95 household sugar samples collected from the accident area. These samples were roughly classified into three types of sugar, fine white sugar, fine brown sugar and coarse brown sugar. The control fine white sugar showed no radical in the ESR spectrum, while those of fine brown sugar and coarse brown sugar showed the presence of a small amount of radicals. It was also shown that, among these three kinds of sugar, the radical concentration of fine white sugar sampled from wooden houses at the area similar to each other did not vary much with the samples, while those of fine brown sugar and coarse brown sugar varied to a considerable extent. Thus, the fine white sugar is considered to be more suitable for the estimation of the level of radiation exposure. The radical concentration of each fine white sugar sample was plotted against the distance from the site of the nuclear accident with a correction of the difference in the shielding effect between concrete houses and wooden houses. The samples obtained at more than 2 km north of the site of nuclear accident showed no ESR spectral signal to a detectable extent. On the other hand, the ESR spectra were observed from the samples obtained within 10 km south and 4 km west of the accident site. These results suggest that the radiation exposure by the contaminant blown by the northeast wind blowing on the day of the accident may occur at the south and west areas.

The first crop of pharmacists graduating from 6-year programs in pharmaceutical l education arrived in April 2012, and it will be important to incorporate new factors when predicting future trends in supply and demand for pharmacists. If we project supply given an exam pass rate of 75%, the supply of pharmacists will increase for the next 10 years or so if the number of exam takers is about 10000, and no decrease in the total number of pharmacists is expected until 2035. At pharmacies, a high degree of demand for the services of pharmacists can be expected to result from increases in the number of elderly patients and the number of patients receiving prescriptions, together with expanded accommodation of home health care, if the proportion of prescriptions that are actually filled up to 70%. At hospitals, demand has been projected to increase over the short term, owing to such factors as the trend toward having a resident pharmacist in each ward, advances in team medicine, and the spread of outpatient chemotherapy. Given the rising enrollment quotas for schools of pharmacy, and if the current supply and demand for pharmacists are maintained, we cannot rule out the possibility that pharmacists will come to be in excess supply within a 10-year horizon if the number of unemployed continues to decrease and the employment rate continues to improve along with changes in economic conditions and the consciousness of graduates of the 6-year programs.

Cinchona is one of the most important medicinal plants as it contains quinine, a potent medicine for malaria. In this review, I reveal the history of cinchona introduction and cultivation in Japan. Cinchona was first introduced to Japan in 1876 from Java based on the proposal submitted by Takeaki Enomoto to the Meiji government. However, the cultivation attempt ended in failure. Later in 1922, Hoshi Pharmaceutical Co. succeeded for the first time in cultivating cinchona in Taiwan, which was then under Japanese colonial rule, and in manufacturing quinine from the cinchona tree in 1934. This was a historic feat in Japan, completing an entire process from cinchona cultivation to quinine manufacture all within the confines of the country. To commemorate this undertaking, the company dedicated a cinchona log harvested for the first time to the Imperial court. It was revealed that a log of unknown origin, which had been left untouched for years at Hoshi University, was the cinchona log from the time of commemoration. Yasusada Tashiro (1856-1928), who has made a great contribution to cinchona cultivation in Japan for over 50 years, led Hoshi Pharmaceutical Co. to success in cultivation.

Because patients and their families are at a high risk of contracting infectious diseases in hospital as well as pharmacy, a pharmacy containing the waiting rooms separately for infectious diseases and non-infectious diseases is expected to lead them to visit with confidence and receive appropriate drug administration guidance without the risk of infection. In this study, we examined the potential usefulness of having separate waiting rooms by conducting a questionnaire survey on the structure of the pharmacy waiting room and investigating the visiting situation for influenza-infected pediatric patients from a record of the medicines they received. As a result of the questionnaire tabulated from guardians of 385 pediatric patients who first visited a pharmacy with separate waiting rooms, 70% of the pediatric patients concluded that having separate waiting rooms would be satisfactory. In addition, the possible risk of horizontal transmission of influenza was supposed to be reduced in the pharmacy with separate waiting room in comparison with the pharmacies without among 211 pediatric patients who could not identify the influenza source within their daily living areas, such as home and school. Based on these findings, we anticipate the growing availability of the pharmacies having separation type waiting rooms.

Recently, because the marked rise in medical expenses in Japan has become a major social problem, self-medication using OTC drugs in cases of minor health problems has attracted increasing attention. When people use OTC drugs for self-medication, they need support and/or advice from pharmacists on their proper use. This paper outlines recent revisions in the legal sales system of OTC drugs, the social background of self-medication, characteristics of OTC drugs and role of the pharmacists in providing consultation on OTC preparations. Next, consumers' views of self-medication and the OTC drug sales system are described based on the results of surveys performed after they attended an educational event on the proper use of OTC drugs. The survey of consumer views on the legal sales system of OTC drugs revealed that they were the most concerned about safety and convenience. From the survey of consumer views on self-medication, a significant percentage of the group who understood the meaning of the term “self-medication” practiced it in cases of minor health problems. Although no significant difference was seen between the groups who understood the term “self-medication” and those who did not in regard to the reading the drug package label and/or insert, a significant difference was found in their understanding of “The System for Sufferers from Adverse Drug Reactions”. Therefore, it was clear that the consumers familiar with “self-medication” not only practiced it, but also understood the contents of drug package labels and/or inserts.

Benzodiazepine receptor agonists (BZDRAs) have been associated with an increased risk of falls in the elderly. However, the association between the elimination half-life (t1/2) of BZDRAs and the difference between benzodiazepines (BZDs) and non-benzodiazepines (Z-drugs) has not been clarified. By conducting a meta-analysis of observational studies, we compared the risk of falls with respect to 1) short-acting BZDRAs (t1/2<12 h) vs. long-acting BZDRAs (t1/2≥12 h) and 2) BZDs vs. Z-drugs in elderly patients. Data were retrieved from MEDLINE, the Cochrane Library, and Igaku Chuo Zasshi. In total, 13 observational studies from 12 articles were included in our study (short-acting BZDRAs, n=12; long-acting BZDRAs, n=9; BZDs, n=13; Z-drugs, n=7). The risk of falls was significantly increased by the use of short-acting BZDRAs [Odds ratio (OR) (95% Confidence interval (CI)): 2.00 (1.46-2.73)], long-acting BZDRAs [OR (95%CI): 2.16 (1.61-2.89)], BZDs [OR (95%CI): 1.67 (1.31-2.13)], and Z-drugs [OR (95%CI): 2.42 (1.35-4.34)] compared to the risk in BZDRAs non-users. The increased risk of falls in elderly patients was similar in each group and unrelated to t1/2. This study suggested that all BZDRAs including Z-drugs should be avoided in elderly patients.

It has been 6 years since the establishment of the position of “sports pharmacist” as one type of pharmacist. In the sporting world of Japan, sports pharmacists are expected to promote athletes' awareness of antidoping regulations and provide them with relevant education. However, currently, these pharmacists' main duty is to provide athletes and their coaches with guidance on medication. Using a model for the prediction of athletes' actions, we have worked to promote athletes' awareness of antidoping regulations and encourage sports pharmacists to perform relevant activities, such as antidoping education. As a result, we clarified that athletes' awareness regarding antidoping rules influences their actions when experiencing minor illnesses. In addition, we have proposed approaches to encourage athletes to undertake antidoping activities. The present study aimed to clarify competitive sports coaches' awareness of antidoping regulations, the instructions that those coaches give athletes when they experience minor illnesses, and coaches' awareness of athletes' usage of drugs and supplements. Analysis using a model for the prediction of actions revealed that to promote coaches' awareness of antidoping regulations, education aimed at raising their level of knowledge of doping is warranted. Furthermore, coaches were aware of the necessity of continuously providing athletes with antidoping instructions, but they did not keep sufficient track of athletes' usage of drugs and supplements. To encourage sports coaches to perform antidoping activities, it is effective to provide them with opportunities to develop their knowledge of doping prevention in their areas.

The scope of pharmaceutical education in Japan has been expanding, and with it an awareness of the importance of team medical care. However, pharmaceutical education still gives little attention to the psychosocial aspects of care, instead focusing on the structures and functions of drugs. In contrast, nursing education emphasizes the fact that medical care involves patients' family and significant others as much as the patients themselves, and thus nursing students are taught the basic needs and developmental stages of those people requiring care alongside their practical nursing skills. In this study, we examined the effect of incorporating certain aspects of introductory nursing education into pharmaceutical education on the self-efficacy of pharmaceutical students. We thus ran an introduction to nursing education course for fourth-year pharmaceutical students (n=86). After the course had finished, we surveyed students about the course. Approximately 94.2% of the students became more interested in team medical care and nearly all (98.8%) thought that what they had learned in the course would be useful in their career. The results indicated that the introduction to nursing education course offered students an opportunity to acquire different viewpoints on clinical situations because the lectures were given by a pharmacist with a nurse license and they were based on his clinical experiences. We therefore propose that more facets of introductory nursing education be incorporated into pharmaceutical education to help students develop their ability to consider patients' psychosocial backgrounds.

Candidiasis is a common opportunistic fungal infection that responds well to amphotericin B (AMPH) treatment. However, AMPH often causes adverse effects such as kidney injury and hypokalemia. Because some essential oils have been reported to have antifungal effects, we investigated the antifungal activity of various essential oils and their major constituents against Candida spp. Most essential oils examined in this study showed antifungal activity, and several enhanced the antifungal effect of AMPH. Clove oil in particular, and its major constituent eugenol, had potent effects. These findings suggest that combining certain essential oils or their constituents with AMPH may be useful for suppressing the adverse effects of AMPH treatment.

In January 2017, counterfeits of the hepatitis C drug 'HARVONI® Combination Tablets' (HARVONI®) were found at a pharmacy chain through unlicensed suppliers in Japan. A total of five lots of counterfeit HARVONI® (samples 1-5) bottles were found, and the ingredients of the bottles were all in tablet form. Among them, two differently shaped tablets were present in two of the bottles (categorized as samples 2A, 2B, 4A, and 4B). We analyzed the total of seven samples by high-resolution LC-MS, GC-MS and NMR. In samples 2A, 3 and 4B, sofosbuvir, the active component of another hepatitis C drug, SOVARDI® Tablets 400 mg (SOVARDI®), was detected. In sample 4A, sofosbuvir and ledipasvir, the active components of HARVONI®, were found. A direct comparison of the four samples and genuine products showed that three samples (2A, 3, 4B) are apparently SOVARDI® and that sample 2A is HARVONI®. In samples 1 and 5, several vitamins but none of the active compounds usually found in HARVONI® (i.e., sofosbuvir and ledipasvir) were detected. Our additional investigation indicates that these two samples are likely to be a commercial vitamin supplement distributed in Japan. Sample 2B, looked entirely different from HARVONI® and contained several herbal constitutents (such as ephedrine and glycyrrhizin) that are used in Japanese Kampo formulations. A further analysis indicated that sample 2B is likely to be a Kampo extract tablet of Shoseiryuto which is distributed in Japan. Considering this case, it is important to be vigilant to prevent a recurrence of distribution of counterfeit drugs.

In 2009, the Japan Anti-Doping Agency (JADA) established the “Sports Pharmacist Accreditation Program” to prevent doping in sports. Since then, anti-doping activities in Japan have been attracting attention. In this study, we investigated research about the current status of doping from 2007 to 2014 in Japan to make anti-doping activities more concrete, and we also discussed future anti-doping activities by pharmacists. In Japan, bodybuilding was the sporting event with the highest number and rate of doping from 2007 to 2014. Many of the positive doping cases were detected for class S1 (anabolic agents), S5 (diuretics and masking agents), and S6 (stimulants). Within class S1, supplements were the main cause of positive doping. Within class S5, medicines prescribed by medical doctors were the main cause of positive doping. Within class S6, non-prescription medicines (e.g., OTC) were the main cause of positive doping. When we looked at the global statistics on doping, many of the positive doping cases were detected for class S1. On comparing the Japanese statistics with the global statistics, the rate of positive doping caused by class S1 was significantly lower, but that caused by classes S5 and S6 was significantly higher in Japan than in the world. In conclusion, pharmacists in Japan should pay attention to class S1, S5, and S6 prohibited substances and to the sport events of bodybuilding. Based on this study, sports pharmacists as well as common pharmacists should suggest new anti-doping activities to prevent doping in the future.

Recent progress in glycobiology reveals that sugar-chains play a crucial role in cell-cell recognition among immunity, inflammation, and malignant tumor in the living body. To study the mechanism of action requires a sample of sufficient quantity. However, isolating a sugar chain and a glycoside in pure form, difficulty follows sugar chain composition again, and studies have been limited to a few sugar chains. Glycosides are a group of compounds known to be the active principle of a natural drug. We have isolated triterpene glycosides from a Leguminosae plant, which improved liver disorder, and steroid glycosides from a plant of the Solanaceous with cytotoxic activity against human cancer cell lines. A biological activity test suggested an important role of the aglycone part and the sugar chain part of those glycosides. Although many studies of sugar chains of glycoprotein and glycolipid are known, there are few examples of studies of the sugar chain function of a glycoside of a natural drug, and the role of a sugar chain of a glycoside for its pharmacologic action expression is unknown. Therefore, as a biological tool investigating the function of a sugar chain of a natural glycoside, we have begun to synthesize a useful “glycoside” which can be utilized as a lead compound having activity.

Pharmacists, being compensated through the new dispensing fee, are required to educate patients on their adhesion to the use of prescribed drugs, and to inventory the levels of leftover drugs in outpatients. Recently, Fukuoka City Pharmaceutical Association started a campaign for regulating leftover drugs (Setsuyaku Bag Campaign). Thirty-one pharmacies joined the campaign. Pharmacists distributed convenience bags, called ‘SETSUYAKU-BAG.’ The patients put their leftover drugs in the bags and brought them to community pharmacies. The pharmacists inventoried the returned drugs and reported their results to the doctors. The doctors adjusted the prescriptions accordingly. We counted and analyzed old and new inventories. The number of leftover drugs was 252, for a total value was ¥839655. Cost of leftover drug prescriptions could be reduced by ¥702695, and the value of drugs thrown away was ¥94801. In total, we could reduce the amount of leftover drugs by 83.7%. The cost of leftover drug for one dose package (ODP) is higher than that for non-ODP. However, there were no significant differences in results per age, sex, number and kinds of drugs, prescription days and premium contribution rate. These results suggest that prescription regulation by inventory of leftover drugs in community pharmacies could significantly reduce overall medical expenses. Further studies are necessary in order to account for patients’ health, and to establish more efficient patient education to raise outpatients’ adherence to the new programs.

A variety of human diseases, including neurodegenerative disorders, ischemic heart disease, diabetes, and cancer have been reported to be associated with mitochondrial dysfunction. Because of this, mitochondrial therapy is expected to be useful and productive in the treatment of such diseases. We previously reported on the development of a MITO-Porter, a liposome-based nanocarrier that permits macromolecular cargos to be delivered into mitochondria via membrane fusion. Intracellular observations using the green fluorescence protein as a model macromolecule provided confirmation that a macromolecule could be delivered to mitochondria in living cells by the MITO-Porter. Here, we present our current findings on the development of mitochondrial medicine and mitochondrial gene therapy based on our mitochondrial drug delivery system (DDS). In this review, we propose “mitochondrial DDS” as a theme for “DDS research for innovative drug development” and discuss the contribution of mitochondrial DDS to innovative drug development.
