Abstract
Increment in amount of medicines prepared in hospital pharmacy was analyzed statistically on the basis of monthly summation of the amount. The number and amount of external liquid preparations, number of ointment preparations and times of regenerations of ion-exchange resin showed close relationship with the month number. The number and amount of oral liquid preparations, number of powder preparations, that of ophthalmic solutions or nasal drops and of clinical reagents exhibited reciprocal relationships with the month number. When the residuals were determined by Run test and Durbin-Watson ratio after significant correlations were estimated with straight lines, the number of oral liquid preparations, number and amount of external liquid preparations, number of ophthalmic solutions or nasal drops, that of ointments and times of regenerations of ionexchange resin were not distributed along the straight lines.
