People with schizophrenia are at heightened risk for physical multimorbidity and premature death. Semaglutide improves cardiometabolic outcomes, yet research is limited among individuals with schizophrenia. This study explored weight loss in Veterans with schizophrenia and physical multimorbidity (ie, heart failure and diabetes) prescribed semaglutide and compared weight changes to those in Veterans without schizophrenia. We hypothesized that those with schizophrenia would experience less weight loss compared to those without schizophrenia.

Competition between firms selling similar drugs is often fostered by policymakers as a means to curb pharmaceutical spending. While firms may compete within these specific drug markets, they also repeatedly encounter rival firms in different markets. This may shape competitive dynamics within and between markets. Yet, multimarket contacts, particularly relevant for multiproduct firms such as pharmaceutical companies, are often overlooked by pricing regulations. This paper investigates how multimarket contacts influence competition between pharmaceutical firms in off-patent markets. Using detailed product-level information on all retail pharmacy sales of generic statin drugs, we quantify the universe of multimarket contacts between firms in these off-patent markets, in Portugal, between 2015 and 2017. We then assess how multimarket contacts affect price competition. To do so, we explore the strict price regulation in Portuguese generic drug markets. Specifically, the Portuguese Internal Reference Pricing System (RPS) defines a price cap for each generic drug. Rather than examining absolute drug prices, we quantify the degree of price competition as the ratio between a firm's drug price and its regulatory price cap (price-to-cap ratio). We find that firms with more multimarket interactions set prices closer to price caps, consistent with the mutual forbearance hypothesis. This effect persists after controlling for brand status, lagged market share, and is not explained by common ownership. Our main results are consistent across alternative model specifications. However, due to limited within-firm variation over time, the effect is not significant in system generalized method of moment instrumental variable estimates. These results suggest that price caps may act as coordination anchors, thus lowering price competition between firms. Policymakers should consider targeted price cap adjustments as safeguards to preserve competition in off-patent drug markets.

Equitable access to essential medicines, which the World Health Organization (WHO) defines as those that meet the priority needs of the population,1 is key to achieving universal health care coverage.(2) However, it is estimated that essential medicines are unaffordable or unavailable to 1 in 4 people worldwide.(3) As governments strive to achieve universal access to essential medicines, it is important to understand how the prices and affordability of these medicines vary between countries. High drug prices strain both personal and government budgets, especially in low- and middle-income countries, where patients often face high out-of-pocket costs.

Although many national surveys of medicine prices and affordability have been conducted, fewer analyses have compared these variables internationally, with most research dating back to 2011 or earlier.(4-20) Many of these studies have focused on high-income countries. Of the studies that also included low- and middle-income nations, most compared the prices of 15 or fewer medicines or included a small number of countries, limiting the generalizability of those findings. Therefore, little is known about the relationship between national income and drug prices. The question remains whether some poor countries routinely pay more than rich countries for the same prescription drugs, possibly owing to weaker pharmaceutical pricing policies.

This cross-sectional study used global data on pharmaceutical sales to compare the list prices of 549 essential medicines in 72 high-, middle-, and low-income markets (covering 87 countries) in 2022, both in nominal and purchasing power–adjusted terms. We also evaluated the affordability of 8 essential medicines used to treat major causes of death and disability globally.
