Biopharmaceuticals are inherently different to other drugs and the following principles guiding their storage, preparation, and handling should be followed:9, 10
- biopharmaceuticals are protein-based agents and refrigeration is often required
- biopharmaceuticals cannot tolerate extremes in temperature when transported such as car boots and aeroplane baggage holds
- use safe handling precautions for biopharmaceuticals that are considered hazardous (e.g. IFN)
- wear gloves when biopharmaceuticals are irritating to the skin (e.g. rituximab)
- when lyophilised product is reconstituted the vial should not be shaken, and the solution should be directed down the side of the vial and not onto powder
- do not shake as this may cause foaming and can denature the protein
- not all biopharmaceuticals are compatible with all plastic syringes and intravenous tubing.
The SCN needs to be familiar with the agents being administered and provide information to individuals on drug interactions.The oral TKI imatinib and the second generation agents dasatinib and nilotinib are all metabolised via the P450 microenzyme CYP3A4.25, 28 Co-administration of certain drugs may increase or decrease the metabolism of these agents. Individuals taking imatinib should be informed of the need to avoid grapefruit products and alcohol due to the increased risk of liver toxicity and P450 interactions.28
