* This table includes subsidised (PBS/RPBS) and non-subsidised use (information from Pharmacy Guild survey). The defined daily dose/
thousand population/day is a more useful measure of drug utilisation than prescription counts. It shows how many people, in every
thousand Australians, are taking the standard dose of a drug every day. (See `Monitoring drug use in Australia' Aust Prescr 1993;16:27-9).
