Health Canada asked 102 drug manufacturers and distributors to stop marketing opioids, 25 responded

This summer, Health Canada asked more than 100 pharmaceutical industry players to stop any and all of theiropioid marketingto health care professionals in Canada. So far, just a quarter of them have written back.

Nearly 4,000 Canadians died from apparentopioidoverdoses last year, up from nearly 3,000 in 2016. As part of the government's response to thecrisis, Health Minister Ginette Petitpas Taylor and the director general of Health Canada wrote to 102 opioid manufacturers, distributors and affiliates earlier this summer asking them to stop pitching the drugs to health care workers while the government considers introducing new regulations.

"I welcome your prompt acknowledgement and action on this request," wrotePetitpasTaylor back in June.

Of the responses, six companies Ethyparm, Mint Pharmaceuticals Inc., Paladin Labs Inc., Pro Doc Lte, Purdue Pharma and Teligentagreed to cease marketing opioids.

Others wrote back to tell the department they don't currently promote or sell opioids in Canada. Indivior Canada, which makes the opioid replacement therapy Suboxone, argued in its letter for a distinction between products prescribed for pain and those meant for addiction treatment.

"Indivior is committed to ethical and responsible marketing and promotion," reads the company's response.

ThierryBelair, a spokesperson for the minister, said theyare "cautiously optimistic" about the results so far.

Purdue Pharma, the makers of OxyContin, publicized their response to the minister back in July. Its letter says the company has stopped actively promoting its prescription opioids in Canadabut would still discuss its opioids with health-care professionals "reactively" by having staff in its medical affairs department deal with "requests for information."

South of the border,the company has acknowledged that its promotions exaggerated the safety of taking OxyContin and minimized the risks of addiction, but its Canadian arm hasn't made any admissions of responsibility.

The province of British Columbia named Purdue Pharma, Paladin Labs and Pro Doc,among others, in its recently launched lawsuit to reclaim costs associated with the ongoing opioid crisis.

The provincial government alleges the companies contributed to that crisis by downplaying the risks of their opioid products particularlytheir addictive potential when advertising them to physicians.

New regulations could be coming

Canada has the second highest rate, per capita, of prescription opioid use in the world, and the number of opioid-related hospital visits and deaths here is rising.

Petitpas Tayor's letters to the drug manufacturers and distributor were meant to act as a stopgap measure while the government decides whether or how to introducerestrictions on the way drug companies market opioids to doctors.

The government has consulted with stakeholders and new regulations could be in place by early 2019.

Those regulations could include new limits on visits by drug companies'sales representatives to doctors' offices,conferences and educational courses sponsored by opioid makersand opioid ads in scientific journals.

"While there is value in the pharmaceutical industry conveying educational and scientific information about a health product," says a poston Health Canada's website,"evidence suggests that the marketing and advertising of opioids has contributed to increased prescription sales and availability of opioids."

Dr. Joel Lexchin, who has studied the industry for close to 40 years, said he'd like to see Health Canada take over drug marketing altogether.

"The biggest issue that Health Canada has to grapple with is the fact that, for virtually the entire existence of Health Canada, it's turned over regulation or promotion to either the pharmaceutical industry itself or to organizations, which are heavily influenced by the pharmaceutical industry," he said.

"I used to teach at York University. The equivalent of what goes on in the drug world would be to tell the students, 'Well, you define what is cheating on the exam and you monitor yourself. And if you're caught, you decide what the penalties should be.'''
