Drug products such as biologics, vaccines and products whose chemical and physio-chemical stability depends on temperature put an added emphasis on pharmaceutical manufacturers to ensure proper handling, storage, transportation and dispensing. Maintaining a secure “cold chain” during the storage, handling and transportation of temperature-sensitive drugs, vaccines and blood products not only assures product quality and integrity for the benefit of the patient, but also helps to keep the manufacturer, hospital, pharmacist, physician and nurse in compliance with various laws, regulations, guidelines and codes.
