Possible Causes of the Drug Shortage

The causes are unknown to most people –patients, pharmacists, and physicians–who are dealing with this problem.

Those who do know the causes are reluctant to publicize them.

The following is a list of possibilities:

    1. Big pharmaceutical companies discontinuing or actively combatting generics in order to enhance sales of newer, more expensive, brand-name drugs. Sometimes companies discourage sales of their own cheaper brands or arrange “deals” in marketing. For an example, click here. For another example, in 2013 a lawsuit has ensued between two American pharmaceuticals Hospira and ICU over marketing practices to Canada. Pharmaceutical companies in various countries are also lobbying for longer patent protection before generic drugs can be released; this concern is part of Canada-European Union free trade discussions. For a discussion, see here. Sometimes pharmaceuticals “tweak” their drugs slightly to apply for a renewed patent in a process called “evergreening.” A landmark case in India, rejected evergreening of an important cancer drug. For an April 2013 discussion of pay-for-delay, click here. In September 2014, New York launched a lawsuit against manufacturers for anti-trust manipulation of Alzheimer market, by deliberately stopping production of a cheaper form to favour a newer more expensive form in advance of patent expiration; the company reluctantly agreed to keep making the drug for 60 more days.
    2. Prices of generic drugs fixed at prices too low to cover manufacturing costs (e.g., in US Medicare). In June 2012, this cause was endorsed by a report of the US Committee on Oversight and Government Reform and by pharmaceutical lobby groups in Europe. In August 2013, it was said to be behind a shortage of essential drugs in India. This “cause” has little traction in Canada where many provinces claim that we pay inflated prices for generics when compared with other countries. See Council of Federation report of July 2012 and Supreme Court ruling on Ontario’s ban on in-house generics in November 2013. See also 2014 article.
    3. Pharmacists choosing not to stock cheaper drugs because profit margin is too narrow.
    4. Shortage of substrate (materials to make drugs).
    5. Growing demand for medicines in developing world.
    6. Manufacturing or quality control breakdowns within production lines owing to lack of investment to improve or maintain standards.
    7. Manufacturing slowdowns owing to greater vigilance by FDA or Health Canada. This cause was characterized as “meaningless red tape” by a report of the US Committee on Oversight and Government Reform in June 2012. The FDA strongly disputes these charges in a letter of 23 July 2012. In May 2014, the same cause was invoked to explain a shortage of paclitaxel in Canada, attributed to Health Canada’s overzealous interpretation of guidelines (see here).
    8. Canada has almost no drug manufacturing industry of its own and is vulnerable to changes elsewhere. Massive layoffs and closures at pharma companies in 2010-12 are said to be owing to the expiration of patents on blockbuster drugs. The 2014 shutdown of Biolyse, which produced 80% of the paclitaxel used in Canada, putting 60 people out of work and resulting in an 80-fold increase in price for the product, which would be supplied by an American firm (see here). These changes further distance sites of manufacturing from Canada.
    9. Legislative changes to financing arrangements for generic drugs, for example in Ontario and Alberta, resulting in declining profitability for pharmacists and manufacturers. These changes provoke cause #3 above. Pharmacists decide not to stock the drugs, and manufacturing further declines in response to lower demand.
    10. No Canadian controls require the pharmaceutical industry to warn of shortages in advance, let alone provide the reasons. Notification is voluntary and, so far, incomplete. Go to Tracking page for current lists.
    11. Political sanctions against countries, such as Iran (e.g. see here).
    12. Moral objections to executions in some US states results in refusal to supply lethal drugs.
    13. Failure to communicate within government agencies. According to the GAO in early 2015, the US Drug Enforcement Administration (DEA) has not effectively coordinated with FDA for administration of quotas on controlled substances needed for making drugs.
    14. Effect of large Hospital Group Purchasing Organizations in USA–creating a “monopsony” (single buyer, many sellers) [also "monopsomy"]. Their unethical and anti-trust business practices, such as vendor kickbacks or “pay for delay” schemes, have placed profit above manufacturing standards and patient supplies. For a shocking example from July 2012, click here. For an April 2013 discussion of pay-for-delay, click here. This cause figured in a report of the US Committee on Oversight and Government Reform, 15 June 2012. In April 2013, the US Supreme Court refused to hear an appeal from a company convicted by jury for using these anti-trust practices. But a US GAO report released in November 2014 tended to absolve the GPOs from wrongdoing by emphasizing how they save money within Medicare. Canada has at least three GPO’s one Medbuy is based in London Ontario. Another HealthPro is in the Toronto area, and a third Sigma Santé is in Montreal. In 2013, clients of the GPO Medbuy in southwestern Ontario experienced an under-dosing error of chemotherapy drugs, which Medbuy blamed on the compounding pharmacy that supplied the drug. In May 2013, it emerged that the Canadian GPO, Health Pro, is a client of the American pharmaceutical Hospira and that 25 of the 136 drugs that Hospira has contracted to supply to HealthPro are on back order. HealthPro broke its contract with Biolyse when the Canadian manufacturer was temporarily shut down owing to a government inspection. No evidence suggests that Canadian GPOs violate anti-trust laws.
