Pharmacists make much efforts to prevent dispensing errors, but actually they cannot avoid such errors. In order to prevent dispensing errors in supply powder preparations to shelf bottle as well as in dispensing and inspection of divided powders, a computerized inspection system was developed. This system is in the marking system with use of barcode in which the drug tariff code established by the Ministry of Health and Welfare is adopted.
Features of the computerized inspection system of dispensing of powder are as follows: 1.It becomes possible to supply powder preparations to shelf bottle exactly. 2. Powder dispensing can be made perfectly by confirming compounding information (maximal dose, permissive weighing error, incompatibility, etc.) in data base, listening to voice recorder for identification of drug name, and keeping record of weighing powder on digital scale and real drug name by barcode. 3. Dispensing error is removed by utilizing console CRT or hard copy of checking prescriptions.
