Microwave thawing of frozen minibag admixtures

An efficient system is described for the preparation of high volume minibag admixtures e.g. cefazolin. The system includes use of bulk reconstitution, freezing and microwave thawing techniques; special admixture dosage forms; and, the use of technical staff. The system can be utilized in any centralized, intravenous, admixture service where the workload is demanding for existing staff.
