Opioid purchases and expenditure in nine western European countries: 'are we killing off morphine?'.
BACKGROUND
In clinical practice the major role of opioid drugs is the management of malignant and nonmalignant pain. The primary aim of this study is to evaluate the trend in sales of four opioid analgesic drugs (codeine, tramadol, morphine, fentanyl), from wholesalers to community pharmacies, as an indicator of opioid consumption in nine European countries in 2001, 2002 and 2003. Secondary aims are to compare: (a) the amount of each drug purchased by different countries in 2003; (b) the average price for each drug in the different countries in 2003; and (c) the total expenditure for each opioid from 2001 to 2003.


METHODS
Data from the Statistical Report on drugs purchased by pharmacies was supplied by IMS Health, an internationally accepted information provider for the pharmaceutical and health care industries.


RESULTS
In the period 2001 2003, while the percentage increase of purchases of fentanyl and tramadol was considerable, that of morphine was the lowest in most of the nine countries. The largest consumer of codeine was the UK and of tramadol was Belgium. The consumption of morphine was the lowest reported in all the countries together and was three times lower than that of transdermal fentanyl. There was a high variability in the costs of the opioids among the different countries. In 2003, the total expenditure for fentanyl reached the highest total expenditure [corrected] followed by codeine. Morphine presents the lowest expenditure in all nine countries and over all three years.


CONCLUSIONS
These results open up many questions. What factors influence opioid purchasing and costs in these European countries? It would be interesting to have the answers from those people who know the actual situation in the individual countries.
