The present invention relates to a method for enabling hospitals or clinics to administer a dose of a drug to patients in need thereof while avoiding steps of manipulation, dilution, reconstitution, dispensing, sterilization, transfer, handling or compounding before intravenous administration. The present invention further relates to a perfusion system comprising different sets of perfusion containers, each container comprising a ready-to-infuse, stable, sterile, aqueous perfusion solution of a drug, wherein the set of perfusion containers alone or in combination provides for direct intravenous administration of a desired dose of the drug to a patient in need thereof, such that the delivered dose is equal to or within ± 5% of the calculated dose.本發明係相關於使醫院或診所能夠將藥物劑量給藥予對其需要的病患並同時避免靜脈給藥前的操作、稀釋、還原、分裝、消毒、轉移、處理或合成之步驟的方法。 本發明係進一步相關於一種灌注系統，該系統包含不同組的灌注容器，每個容器包含立即可注入的、穩定的、無菌的、水性的藥物灌注溶液，其中此組灌注容器單獨或結合地提供所需藥物劑量的直接靜脈內給藥予對其需要的病患，如此所輸送劑量相等於所計算劑量或在該所計算劑量的 ± 5%之內。
