The usual therapeutic doses for the treatment of both angina pectoris and cardiac arrhythmia vary widely among beta-blocking agents, with a maximum of about a 200-fold difference, despite subjects' same clinical improvement at the varying doses. In order to clarify the mechanism of this difference, we analyzed retrospectively the cardiac pharmacological activities of beta-blocking agents based on the receptor occupancy theory by using both their unbound concentrations in plasma at steady state (Cssf), as well as dissociation constants (KB and KI, which were determined by in vitro binding experiments and by in vitro pharmacological experiments, respectively) for a beta 1 receptor. A significant log-linear relationship between Cssf and the KB values was obtained with a slope of regression line of 0.91 (r=0.83, p<0.01). On the other hand, the correlation coefficient of the relationship between Cssf and the KI values was low, with a slope of about 0.5 (r=0.80, p<0.01). The beta 1 receptor occupancies calculated from KB values at the steady state condition after the oral administration of usual doses were almost constant (80.5±16.8%), regardless of the wide variation of usual doses of the drugs. This result indicated that the receptor occupancy may be an appropriate indicator for the pharmacological activity of the drug. Furtheremore, there were significant relationships between the primary pharmacokinetic parameters : Cb/Cf, CLtot/F, and Vdssf, and the octanol/water partition coefficient (PC), with correlation coefficients of 0.80, 0.50 and 0.85, respectively. Accordingly, it is suggested that the prediction of a ususal dose of a new beta-blocking agent can be carried out by using the KB and PC values based on quantitative structure-Pharmacokinetic/pharmacodynamic relationships. This methodology should be very useful for estimating the rational usual dose of a new beta-blocking agent from the animal experimental and physicochemical data in the preclinical study.

It is well known that change in drug distribution occur in association with hepatic disease. The prediction of the variation in the volume of distribution of drugs at steady-state (Vdss) in hepatic disease is very useful for the planning of drug dosage regimens. In the present study, we tried to develop methodology for estimating Vdss in hepatic disease based on physiological pharmacokinetics. The following two methods were utilized to predict Vdss in hepatic disease (hepatic cirrhosis and hapatitis). Method 1 : Vdss in hepatic disease was predicted assuming that Vdss in hepatic disease is not different from that in the normal condition. Method 2 : it is assumed that hepatic disease could not lead to alterations in the tissue binding but in the plasma binding, Vdss in hepatic disease was calculated according to the mass balance equation (Vdss=7.2+7.8·fP+27·fp/fT ; where fP and fT are plasma and tissue unbound fraction, respectively) by using the data of Vdss and fp in normal condition and that in hepatic disease. In hapatic cirrhosis, a significant correlation between the observed and predicted values according to Method 1 was obtained with a slope of regression line of 0.79 (p<0.001). On the other hand, a significant linear correlation between the observed and predicted values according to Method 2 was obtained with a slope of 1.03 (p<0.001). Furthermore, a significant difference in percent errors between the two methods was observed (p<0.05). In hepatitis, same resuls were also obtained. In conclusion, it is suggested that the extent of intrinsic tissue binding of various drugs is little altered in hepatic disease. The prediction of the apparent volume of distribution in hepatic disease according to Method 2 was successful for most drugs studied and very useful for clinical use.

We studied the effect of advising outpatients on the rational use of ophthalmic solutions and compliance by a questionnaire (n=158), in order to establish the optimal consultation method. A total of 41.8% of the patients answered the questionnaire. In compairing the actual use of ophthalmic solutions before and after consultation, the rates of rational use increased for all items except for “applications per day”, which decreased slightly from 93.4% before the consultation to 90.2% after that. In particular, “eyelid closure” and “nasolacrimal occlusion” after instillation, and “the 5 min interval of instillation in the case of plural medication”, considerably increased from 34.8% before the consultation to 60.6% after that, from 9.5% to 50.8% and from 45.9% to 73.8%, respectively. The compliance remarkably improved in glaucoma patients after consultation regarding “the 5min interval of instillation” .Based on these results, our consultation method for the rational use on ophthalmic solutions was thus evaluated. However, since some patients who still did not appreciate the need for the rational use of such medication still presented, further improvements in the consultation method requires for the rational use.

Drug informations on a suitable insertion duration of suppositories and on a deal with the problem of the loss from rectal are essential for the proper therapy of patients. In the present study, we collected the data on drug disposition after administration of commercially available suppositories which had systemic pharmacological effects, and then analized pharmacokinetically on the problems of the insertion duration of them and the loss from rectal. The rectal absorption rate and the cumulative absorption ratio of drugs from commercially available suppositories were estimated by the deconvolution analysis. The plasma concentration data after rectal and intravenous administration were obtained in nine kinds of drugs, which were ampicilline, ketoprophene, indomethacine, acetoaminophene, phenobarbital, donperidone, bromazepam, buprenorphine and morphine. It was shown that the completion time of the absorption of drug from the suppositories varied largely from 50 min for ampicilline to 8 hours for donperidone. Comparing the time periods required to reach to 50% in the cumulative absorption ratio in those drugs, the fastest time was found in ampicilline (15 min), and the slowest was in aminophylline (90 min). These findings make it possible to the persue counseling for the patients on the proper insertion duration of each suppositories. The simulation of the time course of blood drug concentration after the loss of suppositories from rectal and the supplement of them was successfully performed, suggesting that the optimal drug concentration could be controled by the rational supplemental dose. In conclusion, the drug information based on the deconvolution analysis can be useful to instruct a rational use of suppositories to the pharmacist and/ or the patients.

16品種・系統24点の米を用いて米粉試料を調製し,粗蛋白質含量,アミロース含量,損傷澱粉量および粒度構成を測定した.米粉の粒度は全ての供試材料で200メッシュ通過割合が90%以上だったが,粒度構成は米粉試料により異なった.特徴的な品種は300メッシュ通過割合が他種類に比べ高かった北陸166号であり,損傷澱粉量も少ない傾向が認められた.<BR>グルテンを添加混合した米粉の物性を測定したところ,ファリノグラフ吸水率は品種間差が存在し,米粉のアミロース含量との相関が認められた.一方,米粉パンの比容積や形状は米粉試料により異なり,グルテンを添加混合した米粉中のアミロース含量やビスコグラフ特性と相関がある事が示唆された.なお,米粉パンの最大比容積は米粉のアミロース含量が25%前後で得られると推定された.米粉パンの硬度は米粉のアミロース含量と相関が認められた.焼成後の時間の経過とともにパンの硬度は増加したが,品種により硬度の増加速度に違いが認められた.アミロースや蛋白質含量が同程度の品種に比べ,粉質米や低グルテリン米ではパンの硬度や硬化速度が低いものも存在し,米の蛋白質組成等がパン物性に影響を与えていることが示唆された.以上の結果から,中アミロース米(アミロース含量15~25%程度)が米粉パン製造適性に優れると思われた.

We conducted a survey to evaluate a system adopted by the Pharmacy Department of Tokyo University Hospital to address the problem of drug compliance under this system, patients are provided with a "Drug History Handbook", or drug notebook. This survey attempted to determine the extent to which a "Drug History Handbook" helped patients understand the drug they were taking, and the extent to which it was utilized during visits to other institutions. Based on the results of the survey we evaluated the efficacy of "Drug History Handbook" as a means to enable patients themselves to perform comprehensive drug information management. Out of 288 patients respondmg to the survey 149 (52%) had a "Drug History Hand-book"149out of 286 respondents or 40% had been diagnosed at other institutions. The respondents who said they had shown their "Drug History Handbook" to phamacists or physicians at other pharmacies, hospitals, or medical institutions were numbered 7 1 out of 149 (48%), including duplicate responses. At community pharmacies conducted at the same time, responses were obtained from 48 pharmacies. Of the 48 responding pharmacies, 21 (44%) said that patients had presented either "Drug History Handbook"or "prescription cards" From these results, it is clear that the patients thus realized the importance of keeping a complete record of the drugs they had taken, and that presenting information about drug history can be a very valuable aid in both prescribing and preparing appropriate medications. From thus survey, it was found that the use of a "Drug History Handbook" can help prevent the dispersal of information about purchase of over the counter drugs as well as prescription drugs. As a means of patient education, it can also be extremely effective for avoiding the duplicated administration of medications and drug-drug interactions.

We studied the effects of various infusion containers materials on the fluid volumes, different infusion fluids and fluid concentrations of nartograstim (NT), a recombinant human granulocyte colony stimulating factor, on the adsorption of NT to containers, after adding NT preparations (Neu-up^&ltss;[O!R}> for injection 100) into infusion fluids. The NT concentrations in the infusion fluids after adding NT to containers were determined by a high-performance liquid chromatographic method or bioassay. When 1000 ng of NT was added to 500 ml physiological saline in glass containers (final concentration : 200 ng/ml), the residual rates in the fluids was to 89.5% immediately after addition, and thereafter decreased 73.3% at 6 hr and 59.1% at 24 hr. Similarly, when NT was added to the same solution in polypropylene containers, the residual rates was 74.2% immediately after adding, and 37.5% at 6 hr, and 27.8% at 24 hr. The results in the ethylenvinyl acetate and polyethylene containers were also similar to those in the polypropylene containers. No influence of the volumes (100 and 250 ml) or the kinds of fluids (physiological saline, 5% glucose solution and ringer lactate solution) on the residual rates of NT in fluids was observed. As the fluid concentrations of NT were higher, the residual rates were found to be larger within the range of 100- 1200 ng/ml. These decreases in the NT concentrations in the infusion fluids could be prevented almost completely by adding commercially available total-vitamin injections containing polysorbate surfactants.
