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.

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.
