Trends in counterfeit drugs and pharmaceuticals before and during COVID-19 pandemic

The Problems with Online Health Product Sales: How can Regulations be Improved?

With the rapid proliferation of online businesses, national authorities are facing challenges managing the online supply of illegal health products due to the anonymity of the internet, increasing number of global syndicates, new technologies, and inability to enforce against overseas sellers. This paper describes these challenges and the Health Sciences Authority's regulatory approaches to tackle the online sales of illegal health products. These include partnering with platform administrators to remove illegal online postings, leveraging technological tools and relevant legislation, empowering consumers to make informed decisions, and fostering closer collaborations across different jurisdictions to combat online pharmaceutical crimes.

Availability of essential, generic medicines before and during COVID-19 at selected public pharmaceutical supply agencies in Ethiopia: a comparative cross-sectional study

OBJECTIVES

Lockdowns and border closures impacted medicine availability during the COVID-19 pandemic. This study aimed to assess the availability of essential, generic medicines for chronic diseases at public pharmaceutical supply agencies in Ethiopia.

DESIGN

Comparative cross-sectional study.

SETTING

The availability of essential, generic medicines for chronic diseases was assessed at two public pharmaceutical supply agency hubs.

PARTICIPANTS

The current study included public supply agency hub managers, warehouse managers and forecasting officers at the study setting.

OUTCOMES

The assessment encompassed the availability of chronic medicines on the day of data collection, as well as records spanning 8 months before the outbreak and 1 year during the pandemic. A total of 22 medicines were selected based on their inclusion in the national essential drug list for public health facilities, including 17 medicines for cardiovascular disease and 5 for diabetes mellitus.

RESULTS

The results of the study indicate that the mean availability of the selected basket medicines was 43.3% (95% CI: 37.1 to 49.5) during COVID-19, which was significantly lower than the availability of 67.4% (95% CI: 62.2 to 72.6) before the outbreak (p<0.001). Prior to COVID-19, the overall average line-item fill rate for the selected products was 78%, but it dropped to 49% during the pandemic. Furthermore, the mean number of days out of stock per month was 11.7 (95% CI: 9.9 to 13.5) before the outbreak of COVID-19, which significantly increased to 15.7 (95% CI: 13.2 to 18.2) during the pandemic, indicating a statistically significant difference (p<0.001). Although the prices for some drugs remained relatively stable, there were significant price hikes for some products. For example, the unit price of insulin increased by more than 130%.

CONCLUSION

The COVID-19 pandemic worsened the availability of essential chronic medicines, including higher rates of stockouts and unit price hikes for some products in the study setting. The study's findings imply that the COVID-19 pandemic has aggravated already-existing medicine availability issues. Efforts should be made to develop contingency plans and establish mechanisms to monitor medicine availability and pricing during such crises.

Dual-signalled magneto-optical barcodes with lanthanide-based molecular cluster-aggregates

A proof-of-concept for magneto-optical barcodes is demonstrated for the first time. The dual-signalled spectrum observed via magnetic circular dichroism spectroscopy can be used to develop anti-counterfeiting materials with extra layers of security when compared with the widely studied luminescent barcodes.

Dynamic supervision of counterfeit products based on blockchain technology: A differential game on goodwill accumulation

Counterfeiting is a serious problem in many industries, and the annual profit and tax losses caused by counterfeit products in China have reached over 60 billion yuan. The focus of this paper is to study the effect of blockchain technology in terms of supervising counterfeit products as well as product quality and service decisions under blockchain from a dynamic optimization perspective. We consider the role of blockchain when disclosing product quality information and develop a dynamic optimization model before and after blockchain adoption using differential game theory. Meanwhile, we solve the model using the Hamilton-Jacobi-Bellman (HJB) equation and backward induction and conduct parametric, comparative, and numerical analyses of the equilibrium solutions. The main findings are as follows: First, we find that in the absence of blockchain, counterfeit products can reduce brand goodwill and decrease the quality and service level of genuine products; however, supervising counterfeit product sales through blockchain can improve this problem under the critical conditions determined in this work. Second, in the direct sales mode, we find that if the unit operating cost and fixed cost of blockchain are small, the brand owner's adoption of blockchain can not only combat the counterfeiter's profit but also increase its own profit. Third, in the wholesale sales mode, we find that the best conditions in which a brand owner can establish blockchain are only related to the related costs of blockchain, while retailers also need to increase the selling price of genuine products when establishing blockchain. Fourth, we find that supply chain performance and blockchain supervisory effects are sensitive to key parameters through numerical analysis in a quantitative form. These findings have important implications for genuine enterprises in terms of determining the conditions for establishing blockchain to combat counterfeiting and for optimizing product quality and service decisions when using blockchain technology.

Tackling Counterfeit Drugs: The Challenges and Possibilities

Drugs that have been manufactured or packaged fraudulently are referred to as counterfeit/fake/spurious/falsified drugs because they either lack active ingredients or have the incorrect dosages. Counterfeiting of drugs has become a global issue with which the whole world is grappling. The World Health Organization states the frightening figure in which almost 10.5% of the medications worldwide are either subpar or fake. Although developing and low-income countries are the targets of the large-scale drug counterfeiting activities, fake/substandard drugs are also making their way into developed nations including the USA, Canada, and European countries. Counterfeiting of drugs is leading to not only economic loss but is also playing its part in the morbidity and mortality of patients. The recent COVID-19 pandemic fuelled the demand for certain categories of medicines such as antipyretics, remdesivir, corticosteroids, vaccines, etc., thus increasing the demand and manufacture of subpar/fake medicines. This review articulates the current trends and global impact of drug counterfeiting, current and potential measures for its prevention and the role of different stakeholders in tackling the menace of drug counterfeiting.

A narrative review of illegal online pharmacies and contemporary issues with restricting FDA-approved medication access

The rapid growth of technology has transformed the way the public purchases many products, including medications. Online medication purchasing has become a convenient and confidential route for patients to access healthcare without leaving their homes. Online pharmacies have many benefits but also present an increased risk for patient harm caused by unintentionally purchasing from illegal online pharmacies. Illegal online pharmacies are those that operate online without the requisite valid licenses or supply drugs not approved by the Food and Drug Administration (FDA). As obtaining certain medications has become restricted, either due to policy or drug shortages, more patients are relying on services provided by Internet pharmacies. The overturning of Roe versus Wade has caused an emerging drug restriction that may coerce the public to turn to Internet pharmacies for purchasing medications. A narrative review was conducted to analyze both the past and present effects of medications sold by illegal online pharmacies to help recognize the implications of restricting access to FDA-approved medications. Several large science and health literature databases were searched to find relevant references. Resulting resources, which referenced the connection between restricting access to FDA-approved medications and the increase in illegal online sales, were included in this review. The information evaluated in this article will help inform healthcare providers and policymakers of the inadvertent effects of restricting access to FDA-approved medications.
