OTTAWA, ON, Sept. 21, 2022 /CNW/ – This report is the first to use the Drug Shortages in Canada website to provide insight into the issue of drug shortages in Canada. The report takes into account reports of drug shortages provided from April 1, 2017 to March 31, 2020. Its study period, which precedes the COVID-19 pandemic, will provide future researchers with a benchmark for assessing drug shortages. impact of the pandemic on drug supply.

According to the report, shortages were reported for 29% of drugs sold in Canada in 2019-20. However, 91% of drug shortage reports involved non-patented drugs from multiple sources that could be substituted with a product from another manufacturer. Therefore, only a small number of shortages were associated with a large drop in the number of public drug plan beneficiaries submitting claims. These findings provide important context, but are not intended to minimize the adverse effects that certain shortages can have on individual patients and on the healthcare system, particularly when it is not possible to substitute other products for the drugs in question. by shortages or when the dosage form or strength of the drugs is not interchangeable.

About three-quarters of shortages (74%) were reported as “resolved” within six months of their occurrence. Shortages of patented drugs and single-source non-patented drugs were resolved more quickly than shortages of non-patented drugs from multiple sources.
