Oxycodone dispensed use from July 2002 onward for two different data sources (Australian Total and AUS PBS). 

AUS TOTAL is all use of the medicine - subsidised and non subsidised (this latter includes medicine prescribed privately and those medicines priced under the general co-payment [now $36.90 and $6.00 for concession]). AUS PBS is a subset of AUS TOTAL and includes only subsidised use of each medicine through the PBS. Use is measured in DDD (defined daily dose) per 1,000 population/day.
