The pharmaceutical industry has a long history of prioritizing the research and sale of medicines that will yield the largest amount of revenue and placing the health of people second. This gap is especially prevalent in countries of the Global South. This article first explores the dichotomy in research between the Global North and the Global South and then looks at examples of how access to key medicines used in diseases such as HIV, oncology and hepatitis C is limited in the latter group of countries.

Article Synopsis
  • Prescrire International is a French drug bulletin that rates new drug approvals, and this study looks at drugs it rated as "not acceptable" to see if they were also approved in Canada.
  • Researchers checked the reasons for the ratings and compared the approval dates between France and Canada.
  • Most of the drugs deemed "not acceptable" by Prescrire were still available in Canada, raising concerns about whether these drugs are really safe or helpful for patients.

Studies based on the United States Open Payment database have demonstrated an association between the promotion and prescribing of opioids. An equivalent database does not exist in Canada; therefore, I undertook a narrative review of the literature. In 2015, Purdue spent over CAN$4 million promoting a single product and generated over 160 pages of journal advertising.

Cambodia has experienced exponential economic growth in recent years and is expected to graduate from least developed country (LDC) status within the next decade. Membership of the World Trade Organization (WTO) will require Cambodia to grant product and process patents for pharmaceuticals upon LDC graduation. This study aims to measure the impact of the WTO Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) on the price of HIV and hepatitis C medicine in Cambodia once it graduates from LDC status and is obliged to make patents available for pharmaceutical products and processes.

Background: This study examined multiple aspects about the approval of new drugs: the characteristics of the drugs, the quality and quantity of information that Health Canada discloses about the demographics of patients enrolled in clinical trials, the characteristics of the trial, and the type of review that it uses. It examines whether there have been changes in these measures between 1 September 2012 and 31 March 2022.

Methods: A list of all new drugs approved, type of review used, and drug characteristics was generated from Health Canada annual reports.

Semaglutide (▼Ozempic solution for injection, ▼Rybelsus tablets-Novo Nordisk) was initially granted market authorisation for the treatment of type 2 diabetes as an adjunct to diet and exercise. In 2021 and 2022, regulatory agencies in the USA and Europe licensed semaglutide (▼Wegovy solution for injection-Novo Nordisk) for the treatment of individuals who are obese, or overweight and who have at least one weight-related comorbidity. Manufacturer-sponsored randomised controlled trials have shown a loss of almost 12% of body weight over a 68-week period, however, once the medication is stopped people regain most of their pretreatment weight.

Introduction: Privatisation through the expansion of private payment and investor-owned corporate healthcare delivery in Canada raises potential conflicts with equity principles on which Medicare (Canadian public health insurance) is founded. Some cases of privatisation are widely recognised, while others are evolving and more hidden, and their extent differs across provinces and territories likely due in part to variability in policies governing private payment (out-of-pocket payments and private insurance) and delivery.

Methods And Analysis: This pan-Canadian knowledge mobilisation project will collect, classify, analyse and interpret data about investor-owned privatisation of healthcare financing and delivery systems in Canada.

The COVID-19 pandemic showed the close relationship between the Canadian government and the pharmaceutical industry when it came to both domestic and international issues. Domestically, the government chose to prioritize advice about vaccine acquisition from a panel of heavily conflicted people; it signed contracts worth billions of dollars with companies for vaccines but the contents of contracts were largely kept secret. The government also committed over CAD$1 billion in funding for research on COVID-19 but without any requirement that any forthcoming intellectual property or diagnostic and therapeutic products had to be accessible and affordable in low- and middle-income countries (LMICs).

Since 2019, the Chinese central government has taken significant steps to centralize national purchasing power and has implemented a pooled procurement system. In this paper, we provide an in-depth analysis of China's National Volume-Based Procurement (NVBP) policy, which represents a unique approach to pooled procurement within the pharmaceutical sector. The primary objectives of the NVBP are to reduce drug prices, enhance access to affordable medications, and improve the overall functioning of the pharmaceutical industry in China.

The pharmaceutical industry's promotion of opioids in North America has been well-documented. Yet despite the clear consequences of improperly classifying pharmaceutical company messaging and frequently permissive approaches that allow the pharmaceutical industry to self-regulate its own advertising, there has been scarce investigation to date of how pharmaceutical industry stakeholders interpret definitions of "advertising." This study explores how variations of "marketing" and "advertising" are strategically framed by the different actors involved in the manufacturing and distribution of pharmaceutical opioids.
