NHS advice on mixing two licensed products under PGD
13th October 2008
The UK NHS Patient Group Directions (PGD) website has published a frequently asked question entitled "Can two licensed medicinal products be mixed together prior to administration under a PGD?". The information was written in collaboration with the MHRA with some examples to help organisations and practitioners make an informed decision as to whether their practice creates an unlicensed product and therefore cannot be supplied or administered under a PGD. The information does not directly relate to palliative care, however, the MHRA has already confirmed that the mixing of medicines prior to administration by a syringe driver constitutes the creation of an unlicensed product and therefore cannot be supplied or administered under a PGD.
For information on non-medical (independent nurse or pharmacist) prescribing in palliative care, the MHRA recently produced a statement specifically addressing concerns about the mixing of drugs prior to administration via a syringe driver (see link below).

GI bleeding due to interaction between SSRIs and NSAIDs
7th October 2008
A meta-analysis has concluded that the combined use of a selective serotonin reuptake inhibitor (SSRI) and a non-steroidal anti-inflammatory drug (NSAID) may increase the relative risk of an upper gastro-intestinal (GI) bleed six times. It also found that the risk of having an upper (GI) bleed more than doubled in patients taking SSRIs alone, and tripled in those taking NSAIDs alone, compared with controls who were not.
