Ontario Drug Benefit database(1)

In Canada between 1975 and 1996, expenditures on all drugs increased from $1.2 to $10.8 billion, and their share of total health spending rose from 9.7% to 14.4%. Prescription cialis professional made up about 70% of this total in 1994 . Given the level of spending and the important role of pharmacotherapy in modern medicine, research on medication use is essential. Important sources of information on medications prescribed and dispensed in the general population are drug claims databases such as those maintained by the Ontario Drug Benefit (ODB) program.

This database contains records of more than 42 million medications dispensed in 1999 to eligible beneficiaries, which included 2.15 million Ontarians in 1998 (1.23 million people aged 65 years and older, 924,000 people on social assistance, and others). The ODB provides drug coverage for almost half of all medications dispensed in Ontario and the ODB database is the second largest prescription claims database in Canada (second to the Regie de l’Assurance Maladie du Quebec [RAMQ]), which contains records from 55 million prescriptions claims dispensed in 1999).
