We investigated the relation between the pH value of an infusion solution and the decrease of liquid level in a drip chamber in an infusion set. In the study, an infusion solution (not TPN solution) was admixed with sodium bicarbonate solution (Meylon® Injection) and dripped into an infusion set. It was found that the liquid level in the drip chamber was decreased sharply when the pH value of the infusion solution became smaller than 7. Furthermore, with regard to infusion solutions that showed a large decrease of liquid level, the concentration of CO2 in the drip chamber at the start of drip infusion was approximately 2 v/v% in the conventional procedure where no preventive measures were attempted for such decrease, while its concentration was as high as 15 v/v% when preventive measures were attempted for such decrease. As compared with the conventional procedure, there was no difference in the CO2 concentration at 2 hours of drip infusion. These results indicate that the effect of prevention of decreasing the liquid level in the drip chamber was confirmed by changes in the CO2 concentrations in a drip chamber. The concentration of H2CO3 involved in the decrease of liquid level in the drip chamber was approximately 10% of the total concentration of H2CO3, which was confirmed by measuring H2CO3 concentrations at the end of an infusion set when the infusion solution admixed with Meylon Injection, which showed the largest decrease of liquid level in the drip chamber, was dripped into an infusion set.

It has been reported that earthquakes tend to aggravate the physical and mental conditions of diabetic patients in particular due to interruption of their medication and perhaps tremendous deterioration in their living conditions as well.In this study,we conducted a survey of diabetic patients concerning their preparedness for earthquakes at three hospitals in Ehime Prefecture.The results indicated that many diabetic patients did not have a sufficient supply of emergency medicines in the event of such a disaster.In addition,many seemed to be unaware of the names of the medicines that they were taking.Based on these results and previous findings,we prepared"The Disaster Preparedness Guide for Patients with Diabetes" which includes information on medication,food,and ways of monitoring their health.The printed manual was distributed to hospitals in Ehime Prefecture and the PDF file of it was uploaded to the website of Ehime University Hospital.Afterwards,we conducted an anonymous survey of diabetic patients and medical staff concerning this material.Most respondents considered our guide to be useful for learning about disaster preparations.These findings suggest that it is necessary for medical staff to educate diabetic patients adequately concerning disaster preparations.

We have been conducting a four-week practical hospital training course incorporating experience-oriented programs for fourth-year undergraduate students at Ehime University Hospital. There are 17 such programs in the curriculum among them instruction in the self-administration of insulin and bronchial asthma inhalers, nutrition support, drug counseling training using case-based learning procedures and role-play practice (CBL practice), and evidence based medicine (EBM practice) based on the provision of drug information. Self-learning exercises were devised for CBL and EBM practices. At the end of the practical hospital training course, we conducted a questionnaire survey concerning understandability, extent of previous understanding, training time, necessity of each program and degree of satisfaction with it. Analysis of the responses showed that student satisfaction with the practical training program was positively and significantly correlated with understandability (r=0.756, p<0.01) and degree of experience received (r=0.538, p<0.05). However, there was no correlation between satisfaction and previous understanding, training time or necessity. These results suggest that the experience-oriented programs enhanced students' understanding of the hospital practical training and also increased their satisfaction with it.

We determined the adhesion loss in a metering glass for 9 types of syrup for infants,and investigated the relationship between the adhesion loss and the rheological properties of the syrups.There was a good correlation (r2=0.981)between the viscosity of the syrups and percentage syrup residues on the metering glass.Further,from the viewpoints of accuracy and efficiency in dispensing,our finding that percentage residues for a dispenser were much lower (<0.15%) than for the metering glass suggested that it was better to use a dispenser for dispensing viscous syrups with a viscosity of at least 50-60 mPa·s.The results of our examination of syrup viscosities in the present study are expected to be useful information for their administration,and to contribute to the establishment of dispensing procedures based on scientific evidence.

To improve the drug information service and standardize pharmaceutical care for inpatients of the Department of Japanese Oriental Medicine, Toyama University Hospital, we created a Kampo (Oriental) medicine database and used it in the preparation of medication instruction sheets. The database was configured on a Power Mac G4 (Apple Computer, Inc.; Cupertino, CA, USA) personal computer operating on Mac OS 10.4 using FileMaker Pro 6 database software. The database comprised 5 interlinked files-patient registration file, constituent crude drug registration file, Kampo formula registration file, and a file for the making and storing of instruction sheets. Information on 239 crude drugs and 560 Kampo formulae obtained from our "Hospital Manual for Japanese Oriental Medicine" was recorded in the database. Further, color photographs of the plants from which the herbal medicines were derived and other natural medicines were included in the instruction sheets to give patients a better understanding of Kampo pharmacotherapy. The database has made it easy to prepare personalized instruction sheets, which can be done by only entering the patient's ID and the Kampo formulae prescribed or crude drug name. In addition, the medication instructions for each inpatient and the indication(s) of prescribed Kampo formulae have been recorded in the database for later use in the management of inpatient histories and to provide utilization statistics for Kampo medicines. When a questionnaire survey of inpatients of the Department of Japanese Oriental Medicine was carried out to evaluate the usefulness of the medication instruction sheets prepared using the database, it was found that they gave patients a better understanding of Kampo pharmacotherapy and made them more interested in it. In conclusion, our database system will help improve the drug information service and quality of pharmaceutical care for inpatients treated with Kampo formulae prepared from crude drugs.

To evaluate the economic impact of regimens including the oral anticancer drug S-1 (a combination of tegafur, gimeracil, and oteracil), we performed cost-minimization analysis to compare the medical costs of S-1 plus irinotecan (IRIS) with those of conventional intravenous treatment with oxaliplatin or irinotecan plus fluorouracil and folinic acid (mFOLFOX6/FOLFIRI) in patients with advanced colorectal cancer. Patients with advanced colorectal cancer were extracted from the ordering system database for outpatients in Showa University Hospital. Direct medical costs and patients' time-related costs were calculated from the hospital billing data and the average Japanese labor wage, respectively. The results were analyzed from a limited societal perspective. Twenty-nine patients with advanced colorectal cancer were identified, and 25 IRIS regimens, 11 mFOLFOX6 regimens, and 5 FOLFIRI regimens were registered. Mean (± SE) monthly costs of treatment were 183,682 (± 4,767) yen for IRIS regimens and 279,077(± 13,345) yen for mFOLFOX6/FOLFIRI regimens. The monthly cost of IRIS regimens was significantly lower than that of mFOLFOX6/FOLFIRI regimens (P < 0.0001). IRIS regimens are cost-saving compared to mFOLFOX6 or FOLFIRI regimens for the management of advanced colorectal cancer.

Pharmacists can play a significant role in medical care by helping to ensure the proper use of drugs, and a knowledge of pharmacokinetics is indispensable for this. Therapeutic Drug Monitoring (TDM) is a pharmacy practice that involves the full use of such knowledge. Practical training in TDM in pharmacist education should thus be an optimal way acquiring skill in applying pharmacokinetics knowledge in the clinical setting. However, in the Model Core Curriculum for practical training at hospitals implemented in 2010, there is only 1 specific behavioral objective (SBO) concerning TDM, and only 1 day is given to training on TDM. With this in mind, we developed an original experience-based TDM curriculum that includes 5-days of practical training. The curriculum was introduced for students in the 2010 pharmaceutical internship to evaluate its components.All students who took our curriculum considered that the 1-day of TDM training stipulated in the Model Core Curriculum was not sufficient, and that around 5 days of training, the period we have set, would be necessary. They also indicated a high level of satisfaction with it, viewing the training components as appropriate. These findings suggest that our curriculum would be effective.

To investigate the description of the expiration date and manufacturing number on the drug packages, "pillow" packages and "heat-seal" packages, the questionnairing was carried out to pharmaceutical companies. Fifty-six drugs consisting of three hundred thirty-seven items, with sales of over 10 billion yen in 1998, were investigated at the corresponding 26 companies. The recovery rate of the questionnaire from the company was 100%, and the answer for all questions was also perfect. Three hundred fourteen items (93%) have had description regarding the manufacturing number and/or the expiration date on the heat-sealed packages. The manufacturing number took precedence over the expiration date. Of 269 pillow packages, 69 items (26%) have had description of manufacturing number and/or expiration date on the pillow package. There were 41 products (12%) that the company did not guarantee an expiration date being described on the box container when the packages were taken out from the box container. As a result, the description of the manufacturing number and expiration date on the packages, "pillow" and "heat-seal", is still not complete even though the companies guarantee the expiration date when the drugs were stored with these packages. Since the information of the expiratioh date is necessary for the appropriate management of tablet and capsule products, it is required to describe manufacturing number and expiration date on every drug package including "pillow" and "heat-seal" packages.

With the introduction of 6-year pharmacy educational program in 2006,a provision was made to assign pharmacist faculties having working experience as pharmacists in pharmacy schools.In October 2007,we conducted a survey to investigate the situation of pharmacist faculties.We sent a questionnaire to 247 pharmacist faculties in 66 pharmacy schools and the response rate was 84.9%.The faculties consisted of professors (43%),associate professors (23%) and lecturers (23%),and 77% of them had a Ph.D.degree.In a typical week,the major activities they engaged in were educational activities (20.6 hrs),research (12.2 hrs) and management (9.6 hrs).While the average time they were occupied by clinical practice was 3.5 hrs,67% of them did not do any.Half of the faculties did not conduct any research with students or graduate students in their own schools,and in 2007 only 55% applied for Grant-in-aid for Scientific Research from the Ministry of Education,Culture,Sports,Science and Technology of Japan.Twenty-six percent said they were very satisfied or satisfied with their work on a five-point scale,and 44% rated their degree of satisfaction as fair.In conclusion,our survey showed that most pharmacy faculties are not sufficiently engaged in clinical practice and do not spend much time in clinical research.We hope that its results will promote discussions among pharmacy personnel concerning the role of pharmacist faculties so that even better clinical pharmacy education may be provided to students in pharmacy schools.

Fluvoxamine, a selective serotonin reuptake inhibitor (SSRI), is widely used in the treatment of patients with depression. It is known that fluvoxamine inhibits the activity of human cytochrome P450 enzymes (CYP) responsible for the oxidative metabolism of many drugs. Inhibition of CYP results in a number of clinically important pharmacokinetic drug interactions.Therefore, the interaction between warfarin and fluvoxamine was evaluated. The patients treated with fluvoxamine were selected from the prescription database file made for the prescriptions order entry system, which contains all the prescriptions filled for the inpatients and outpatients. There were 106 patients treated with fluvoxamine between July 2000 and June 2001. Of 106 patients, 20 used warfarin concomitantly during the study period. Increased INR/Dose values were observed in all patients after the initiation of fluvoxamine therapy. Subsequently, the high INR/Dose values were observed during the concomitant use of warfarin and fluvoxamine (P<0.01). It is suggested that the increase in the anticoagulant activity of warfarin occurred when fluvoxamine is used concomitantly. Therefore, frequent coagulation tests are required in patients treated with warfarin after the initiation or discontinuation of fluvoxamine therapy. In conclusion, warfarin should be used with worry when fluvoxamine is used concomitantly.

Smoking is a risk factor for pulmonary diseases,cardiovascular diseases and many other morbid conditions but it is difficult to get patients to cease smoking due to the strength of nicotine dependence.As one of our pharmaceutical management and counseling services,we conducted a smoking cessation intervention program for inpatients in which we counseled them on the proper use of nicotine replacement products using a smoking cessation guidebook,and evaluated the usefulness of such counseling.We interviewed 228 patients and from among them enrolled 18 current smokers and 11 people who had stopped smoking during the past 30 days as subjects.The content of the program was evaluated through a questionnaire survey of patients and the success of the counseling by pharmacists was evaluated by smoking cessation status at discharge.Immediately after the program,44.4% of the smokers had ceased smoking and this figure had increased to 83.3% at the time of discharge.All subjects who had stopped smoking during the past 30 days continued to refrain from smoking until discharge.The results of the questionnaire survey showed that the use of a smoking cessation guidebook in the intervention enhanced awareness of the importance of ceasing smoking in 89.7% of the subjects.Though they were frequently made aware of nicotine replacement products,only about 10% had wished to use them.The findings of the questionnaire survey suggest that our smoking cessation intervention program for inpatients involving counseling on the proper use of nicotine replacement products improved patients’awareness of the importance of smoking cessation and reduced the smoking rate.

Octreotide is often administered to patients by addition to total parenteral nutrition (TPN) as well as by subcutaneous injection. However, the concentration has not been determined to remain greater than 90% through the completion of its administration. This study investigated the stability of octreotide during administration in ELNEOPA No 1 TPN solution, a four-chambered duplex delivery system.The level of octreotide in the upper-chamber of the ELNEOPA No 1 duplex delivery system, pH 4.0, remained stable, whereas that in the lower chamber, pH 7.0, decreased to less than 90% of the initial concentration immediately after mixing. The final concentration of octreotide in pH 7.5 buffer solution was significantly lower than that in pH 5.1 buffer solution. The influence of pH was reversible. However, a fraction of octreotide suffered decomposition in pH 7.5 buffer solution. Hence, it might be suitable to inject octreotide into the upper chamber that has the lowest pH among the 4 chambers of the duplex drug delivery system used by ELNEOPA No 1.Reducing agents such as sodium hydrogen sulfite caused the concentration of octreotide to decrease. Although the mixed solution of the 4 chambers contains sodium hydrogen sulfite, the concentration of octreotide remained greater than 90% for about 3 days. The decrease in concentration caused by sodium hydrogen sulfite seemed to be protected by the co-presence of glucose or cysteine.The results of our octreotide concentration studies suggest the possibility that the therapeutic effects of octreotide administered via TPN would be equivalent to the effects following subcutaneous administration.

Very little information is provided with OTC drugs and unlike prescription products,they do not have package inserts or interview forms.The purpose of this study was to examine the stability of 5 acetaminophen-containing OTC drugs by observing temporal changes in their characteristic physico-pharmaceutical parameters (hardness,mass,elution,drug migration) when they were preserved under conditions in which temperature and humidity were altered.From the results,it was assumed that 3 of the 5 drugs were affected by temperature and humidity,and that it was difficult to maintain stability when they were taken out of their packages.In particular,the drugs seemed to be more adversely affected the higher the temperature was and changes in parameters were greater.Also,the results of an elution test conducted after 24 hours of storage suggested that there was deterioration in 3 of the products.In conclusion,our findings clearly showed that patients need adequate explanation on how to keep OTC drugs.

Very little quality information is available for generic pharmaceutical preparations and this is particularly so for injectable preparations for which few quality studies have been conducted. With this in mind, we conducted an inter-lot quality variation investigation on nafamostat mesilate preparations for both the original and generic products and compared the results. The investigation involved measuring amounts of impurities other than those of the active ingredient by high performance liquid chromatography.For the nine generic products investigated, impurity amounts were about 2.4 times that of the original (min. 2.0 times-max. 3.1 times). We determined that these differences were not due to hydrolysates of the active ingredient but to unknown substances since the amounts of these unknown substances in the generic products were about 5.7 times (min. 4.7 times-max. 8.0 times) their amount in the original product.Concerning inter-lot variation (maximum value-minimum value), we found that the variation in total impurity amounts for the generic products was 1.8 times (min. 0.7 times-max. 2.8 times) that of the original product, while the variation in unknown substance amounts for the generics was 3.1 times (min. 1.0 times-max.4.6 times) that for the original.The results of the present study suggest that it is necessary to take inter-lot variation into account in evaluating the quality of generic products. They also suggest that the higher contents of unknown impurities in the generics could be a cause of the in-circuit precipitation which has been reported with generic versions of nafamostat mesilate during blood purification in the clinical setting.

One of the major adverse effects of Shakuyaku-kanzo-To (SKT),a herbal medicine containing licorice,is licoriceinduced pseudoaldosteronism with hypokalemia and hypertension.Owing to the risk of hypokalemia,caution should be therefore exercised when SKT is co-administered with potassium lowering drugs.In order to clarify this risk,we examined the occurrence of hypokalemia in 103 patients receiving SKT.Thirty (29.1%) of the 103 patients developed hypokalemia and SKT dosing periods tended to be longer in these patients than in those who did not develop hypokalemia (54.5 vs.23.0 days,respectively).The co-administration of potassium lowering drugs was more frequent in the patients with hypokalemia (90.0% vs.64.4% for no hypokalemia p<0.01).The occurrence rates of hypokalemia varied with drugs co-administered with SKT ; with 75.0% for glycyrrhizin preparations,47.2% for diuretics,41.9% for glucocorticoids,20.0% for sennoside preparations and 25.0% for others.The above results confirmed that the co-administration of potassium lowering drugs enhanced SKT-induced hypokalemia.Frequent serum potassium monitoring is therefore required when potassium lowering drugs,especially glycyrrhizin preparations,diuretics and glucocorticoids,are co-administered to patients receiving SKT.

Among the adverse effects of anticancer drugs, critical effects have attracted the most attention. However, non-critical adverse effects that lower the quality of life of cancer patients have been gaining recognition. For example, the package insert of tegafur・gimeracil・oteracil potassium (S-1) was modified and lacrimal duct obstruction was added to the list of critical adverse effects on September 25, 2012. In a similar vein, this study aimed to examine the awareness of healthcare professionals regarding the adverse effects of anticancer drugs on the eyes. A web-based questionnaire survey was administered to medical doctors and pharmacists. We received responses from 38 doctors and 123 pharmacists. Only 39.5% (15) of the doctors and 33.3% (41) of the pharmacists were aware of the adverse effects of anticancer drugs on the eyes. Among respondents who had observed these adverse effects, only 12.5% (1/8) of doctors and 11.1% (2/18) of pharmacists reported them to the authorities or the pharmaceutical companies. The results suggest that the adverse effects of anticancer drugs on the eyes should gain more recognition among healthcare professionals. Therefore, we would like to encourage them in obtaining information concerning the safety of medicines and to report all observed adverse effects regardless of their severity.

We examined the procedures for dispensing tablets or capsules that are not approved for crushing after checking the basis for such non-approval regarding 108 medicines introduced in our hospital. The problems are summarized as 1) a reduction in the pharmacological efficacy, 2) lowering the compliance due to a bitter taste or unpleasant odor, 3) dispersing hazardous powder, and 4) a disappearance of the efficacy of improved formulation such as for enteric coating.The taste of the ground tablets or capsules that are indicated to not be crushed was examined and compared with various concentrations of quinine hydrochloride powder in 8 healthy volunteers who showed a normal response to a bitter taste. Thirty-one out of 43 drugs were found to be tolerable to the taste, in which 13 drugs were less bitter than 0.5% quinine hydrochloride powder. However the other drugs either induced numbness or had a pungent taste and unpleasant odor, which were also considered to become the major reasons for nonapproval for crushing. Therefore, we found that several tablets have no serious problems, when they are dispensed after grinding. On the other hand, a number of hygroscopic medicines and anticancer agents tended to easily disintegrate in water. As a result, they can be prescribed by suspending them in water immediately before taking them. Our findings suggest that several tablets or capsules that are non-approved for crushing may thus be dispensed without any serious problems after crushing or disintegrating them in water. Therefore, our present findings may offer some useful information on the countermeasures for dispensing tablets and capsules that are not approved for crushing.

Anxieties about the quality of generic drugs are one of reasons why these drugs are not generally used in therapies in Japan. To reduce anxieties, we propose a statistical and objective method to evaluate the quality of generic drugs using the coefficient of variances (CVs) calculated from their pharmacokinetic parameters. CVs were estimated from AUC, Cmax, Tmax, t1/2, and MRT, which were provided as publicly-available drug information. The generic drug assessment tool (G-DAT), an original equation derived from the ratio of CVs of corresponding generic to original drugs, and the quality of generic drugs was statistically evaluated. As expected, when evaluated with G-DAT, there was little variance between original and generic drugs using 11 medicines. Antihypertensive dihydropyridines with a lower solubility were shown to have a larger CV. No significant difference in CVs was observed when famotidine and ebastine OD tablets were taken with or without water. G-DAT and the ratio of CVs (CCVs) of generic to original drugs revealed pharmacokinetic equivalences between generic and original drugs. The proposed comparative evaluation showing equivalent pharmacokinetics of generic to original drugs can be used as one solution to reduce anxieties and increase the reliability of generic drugs.

Pharmaceutical support systems for anti-neoplastic drug preparation for chemotherapy in hospital information systems are in need of improvement. With this in mind we developed a new support system in collaboration with system engineers (SEs) in January 2005. In the presentation of our requirements for the support system to the SEs, the most important part of the development process, we proposed a development model based on an end-user prototype system. The model comprised a five-step design and development of the prototype system through end-user computing, evaluation of the prototype system through actual use, the introduction of a step to determine the exact task requirements, detailed discussions with the SEs, and installation. Among the functions of the prototype system were support functions for the input of prescriptions, inventory management and task data assessment and a print-out function for record sheets. This model produced excellent results for the upgrade whose express purpose was the introduction of an end-user computing step. Furthermore, to evaluate the preparation support system, time-determinative factors involved in the preparation were analyzed and compared using data collected in November 2004 and March 2005. In the evaluation, two pharmacists dispensed a total of 791 and 1003 admixtures for 341 and 426 injection prescriptions, respectively, and the average preparation times were 18.15 and 15.43 minutes/prescription, respectively. Multiple regression analysis revealed several time-determinative factors with correlation coefficients of 0.803 and 0.668. The significant time-determinative factors were the number of vials, ampoules, and bottles for admixtures and the properties of drugs dispensed. The new system has resulted in improved patient safety and operational efficiency.

We conducted a home medical care (HMC) training workshop consisting of presentations given by regional HMC leaders that targeted community pharmacists in collaboration with a nearby pharmaceutical association. Subsequently, we conducted a questionnaire survey with the pharmacists in attendance to assess their opinions of the present HMC situation. The participants' satisfaction with the workshop was relatively high, at an average of 8.13 out of 10. Among the participants, 70.9% had experience with HMC, such as visiting pharmacy services at patients' homes, with the most frequently practiced activity being “drug administration guidance for patients at home.” However, activities such as “accompanying medical rounds” and “participation in home care conferences” were not widely practiced (at a rate of less than 50% of the most popular activity) among the participants. Next, many participants responded that the key HMC factors were the creation of systems of cooperation between different professionals and their environmental arrangements. Participants also made suggestions for future lectures, such as on the subjects of contract procedures and HMC case reports. Furthermore, the participants suggested that the qualities necessary for effective HMC were a wide and practical knowledge of HMC and a positive attitude. In conclusion, many patients stated that cooperation with other professionals is important in deepening pharmacists' HMC involvement, and the pharmacists hoped to establish greater communication between pharmacists and other HMC workers.
