Investigation and inquest
On 11 January 2021 I commenced an investigation into the death of Amy Anne June Ganner, aged 26 years. The investigation concluded at the end of the inquest on 22 June 2021. The conclusion of the inquest was Misadventure. The medical cause of death was 1a) Combined Drugs Toxicity.
Circumstances of the death
Against a background of complex health conditions with chronic pain the deceased inadvertently ingested an excessive amount of prescribed medication prior to being discovered on 6th January 2021.
Coroner’s concerns
The deceased had suffered with chronic pain from complex medical conditions for several years. Her medication included Tramadol capsules; Zomorph modified release capsules and morphine sulphate oral solution all of which were opioid drugs associated with central nervous and respiratory depressant effects. Their individual effects would be enhanced when taken in combination and these depressant effects would be exacerbated by her use of the other drugs appropriately prescribed for her. As for all opiate cases the toxicological significance of the morphine concentration will depend upon the degree of tolerance possessed by the deceased. In this case as the opiate based medication was prescribed for her and being used regularly she would be expected to have a degree of tolerance. However it is known and was asserted in evidence that tolerances can be quickly lost, in the event of a period of abstinence; that the diminution of tolerance varies from person to person and is extremely difficult to predict. Whilst the deceased was intelligent and had a clear understanding of the risks, benefits and role of her medication both her general practitioner who gave evidence and I believe that it would be extremely helpful if the Department of Health was to support the production of a leaflet in both electronic and paper formats dealing with the concept of ‘tolerance’ and emphasising the serious risk of toxicity which would be available to all whom are prescribed opiate based medication
