We conducted training in communication skills as part of the pharmaceutical care training for graduate students studying at the Graduate School of Pharmaceutical Sciences, Nagasaki University. In this study, we made a questionnaire survey of the graduate students' views on this pharmaceutical care training program. The results showed that almost all students found the communication skills training to be useful in helping (simulated) patients to comply with instructions. This communication skills training is thus considered to be useful for improving pharmaceutical care training for graduate students training to become hospital pharmacist's section.

THEODUR® Tablets 100 (TDR·T) and THEODUR® Dry Symp 20%(TDR·DS) are sustained-releasepme pamations of theophylline. The dissolution test was used to examine the effects of TDR·T and TDR·DS soaked with milk on the release of theophylline from these preparations. The dissolution of theophylline from TDR·T soaked with milk was slower than that of the control thus indicating a delay in the release of theophylline. Milk did not affect the dissolution of theophylline from TDR·DS. In conclusion, the diffemence between the structures of TDR·T and TDR·DS seemed to produce dif5erences in the dissolution of theophylline soaked with milk. Accordingly, patients are recommended to take TDR·T with water apd not with milk.

To reduce the time and cost needed to make hospital preparations, an automatic dispensing device to prepare disinfectants was developed. We prepared 200 bottles of disinfectant (500 mL) containing 7% ethanol and 0.1% benzalkonium chloride with an automatic device and 200 bottles using the manual process, and then randomly selected preparations were evaluated concerning variations in drug concentrations, stability for long periods and preparation cost. The variations in the drug concentrations in the preparations made with the device were narrower than those observed when using with the manual process. Although the volume of the preparations with the device was less than that when using the manual process, the variation range in the volume in both preparations was similar. Both preparations were stable for 4.5 months at room temperature. The preparation time and cost using the device was about half of that when using the manual process. These results indicate that our automatic dispensing device was found to be very useful in preparing disinfectants.

The effects of an α-glucosidase inhibitor, acarbose on serum lipoproteins as well as hemoglobin A1c were studied in type 2 diabetes mellitus patients. Furthermore, the improving rates of hemoglobin A1c and serum lipoproteins were compared between the patients with and those without patient-counseling by a pharmacist.Acarbose was administered to 55 poor control type 2 diabetes mellitus patients for 4 months. Overall, the level of HbA1c was reduced by 1.55%. The reduction in patients with patient counseling (PC, n=17) was 2.1% while that in patients without such counseling (non-PC, n=38) was 1.05%(p<0.01). Total cholesterol and triglyceride levels were reduced in total by 7.7%, 21.8%, respectively, but the rate of decrease was significantly larger in PC than in non-PC patients (8.8% vs 5.3% for total cholesterol, 29.3% vs 10.1% for triglyceride, both p< 0.001). The Midband, which migrated between VLDL and LDL on polyacrylamide disc electrophoresis disappeared in 45% of the patients, and the Midband of PC disappeared in 60% of the patients, whereas the same rate for non-PC was 35%.These results suggested that the delayed glucose absorption by acarbose in type 2 diabetes mellitus improved the serum lipoproteins as well as the blood glucose level, and that patient counseling by a pharmacist significantly improved the efficacy of this agent.

( Received September 27, 1999 Accepted March 6, 2000 ) The purpose of this report is to clarify the relationship between the dosage of furosemide and the occurrence of hyperuricemia. 59 patients with heart failure who were treated with furosemide were analyzed retrospectively. We defined hyperuricemia to be more than 7.0mg/dL in males and 5.5mg/dL in females. Any patients with renal failure, gout, diabetes mellitus and an abnormal purine-metabolism were excluded from this investigation. The frequency of hyperuricemia was 78.0% in the 59 patients receiving furosemide. The incidence of hyperuricemia due to furosemide medication was as follows: 80% in the 20mg treated group (n=10); 81.5% in the 40mg treated group (n=27); 100% in the 60mg treated group (n =2); and 100% in the 80mg treated group (n=14) . Furthermore, in the groups receiving 20 mg, 40mg and 80mg of furosemide, the average doses of allopurinol (urate synthesis inhibitor) were 50.0•}16.7mg (mean•}SE, n=10), 88.5•}15.0mg (mean•}SE, n=26) and 130.2•}26.0mg (mean•}SE, n=10), respectively. These results indirectly suggest that the increases in the amount of furosemide correlated with the serum urate level. In conclusion, to avoid hyperuricemia, the serum urate levels should be carefully checked in

The influences of both the mixing ratios of Witepsol as a lipophilic base and the temperature on the drug release from the zonisamide suppositories was investigated. Mixed types of zonisamide suppositories consisting of Witepsol H-15 (H) and Witepsol S-55 (S) as a lipophilic base were prepared and the release of zonisamide from a suppository was determined using the dissolution apparatus in Paddle method of JPX III. The release rate of zonisamide from the Witepsol (H: S=4: 1) suppository and Witepsol (H: S=3: 1) suppository at 4 hours after start of the release test were 66.6% and 56.5%, respectively. The former was significantly higher (p<0.05) than that of the latter. The release volume and mean dissolution time (MDT) of zonisamide from a suppository increased and decreased, respectively, according to the high mixing ratio of Witepsol H 15.The effect of low temperature (32 and 34°C) on drug release from the zonisamide suppositories was also studied using artificial membranes. The drug release properties were changed according to the mixing ratios of the two lipophilic bases and the temperature of the fluid tested. At a low temperature, the amount of released zonisamide correlated with the ratio of Witepsol S 55 in the suppository. However, the amount of the drug released from the zonisamide suppositories decreased at temperatures lower than normal body temperature. These results indicate that the ratio of Witepsol H 15 and Witepsol S 55 in suppositories was important while the temperature also influence drug absorption from the rectum with zonisamide suppositories.

In order to study the pharmacokinetics of vinorelbine and provide information necessary to determine the optimal therapy, a specific and reliable method to determine the levels of vinorelbine in biological fluids is required. We, therefore, established a highly sensitive and specific assay method for vinorelbine in biological fluids using reverse phase HPLC. The vinorelbine level was determined using HPLC with UV detection at 268 nm, combined with liquid-liquid extraction using diethyl ether for sample clean-up. The HPLC system used an ODS column and a mobile phase of 48 vol% methanol containing 0.05 vol% trifluoroacetic acid. The absence of endogenous interference and the excellent chromatographic behavior of vinorelbine provides accurate results even at low concentrations. The limit of determination is 2 ng/mL (100μL, sample), and the range of the assay is from 2 to 200 ng/mL. Consequently, this method is thus suggested to be highly sensitive and specific for determining the vinorelbine levels in biological fluids. Using this method, we measured the plasma concentrations of vinorelbine after a single intravenous administration of vinorelbine at 1.2 mg/kg in male rats. The plasma concentration ofvinorelbine disappeared triphasically after the intravenous administration of the drug.Based on these findings, this method is considered to be useful for drug monitoring of clinical specimens and also for basic studies, using small animals.

A 55-year-old woman is described whose serum calcium and phosphorus levels had to be controlled by the administration of calcium salts due to the absence of normal parathormore secretion after the removal of her thyroid gland. After the operation, the serum calcium levels were well controlled by the administration of calcium carbonate and alfacalcidol. However, after the added administration of famotidine, the serum calcium level decreased within a few days, and the appearance of tetania was observed. As a result, the daily dosage of calcium carbonate and alfacalsidol were increased, however the serum calcium level still did not improve. When the administration of famotidine was stopped, however, the tetania was disappeared and the serum calcium level increased. The findings of this case suggest that the calcium carbonate became insoluble in water due to an increase in the intragastric pH level caused by the addition of famotidine, which led to a decrease in calcium absorption from the small intestine.

A 2-year and 5-month old male child was admitted to our hospital, deu to signs of antiepileptic drug intoxication. He had been administered zonisamide and valproic acid for the treatment of epilepsy. One day after taking the medicines prepared in an outside pharmacy according to the doctor's prescription, he showed ataxia. The serum valproic acid concentration was within the normal therapeutic range, when measured using the fluorescence polarization immunoassay method (FPIA). We assayed the zonisamide concentration in patient serum using the capillary electrophoresis method. The peak of zonisamide was very low, but another extremely high peak was found. This peak was identified as phenytoin based on the migration time and absorption spectrum. We therefore concluded that the patient fell into phenytoin intoxication by taking a large amount of phenytoin that had been incorrectly prepared. The capillary electrophoresis method appears to be useful for therapeutic drug monitoring, especially in drug intoxication, because of its specificity of separation, simultaneous determination, speed of analysis, and small injection volume.

He had been administered zonisamide and valproic acid for the treatment of epilepsy. One day after taking the medicines prepared in an outside pharmacy according to the doctor's prescription, he showed ataxia. The serum valproic acid concentration was within the normal therapeutic range, when measured using the fluorescence polarization immunoassay method (FPIA). We assayed the zonisamide concentration in patient serum using the capillary electrophoresis method. The peak of zonisamide was very low, but another extremely high peak was found. This peak was identified as phenytoin based on the migration time and absorption spectrum. We therefore concluded that the patient fell into phenytoin intoxication by taking a large amount of phenytoin that had been incorrectly prepared.

The serum drug concentrations in 6 cases of acute hydroxyzine intoxication patients were measured by HPLC. The patients were admitted about 1-10 hours after ingesting from 200 to 15000mg hydroxyzine. The serum hydroxyzine levels were within a range of 0.12-1.70μg/mL. The elimination half-lives were within a range of 4.7-111 hours during treating the patients by forced diuresis. The serum hydroxyzine levels associated with drowsiness was>0.51μg/mL, while that associated with vomiting was >0.51μg/mL and that with is miosis was> 1.40μg/mL. Only one fetal case was encountered. However, the fetal case could possibly have been due to trazodone rather than hydroxyzine because the concentration of hydroxyzine was 0.12μg/mL.
