Fake drugs, real concerns: Counterfeit HIV medications and community trust.

Counterfeit medications infiltrate drug supply chains at various entry points. While scientific advancements continue to deter counterfeit medications, these imitation therapies still manage to circumvent national and international regulations to reach unsuspecting consumers. Certain manufacturers of human immunodeficiency virus (HIV) prevention and treatment medications within the United States recently encountered counterfeit versions of their therapies that in some instances contained antipsychotic and pain reliever products. People on HIV treatment or those taking HIV prevention therapies who consume counterfeit medications are at risk of having their HIV management strategies compromised or seroconverting from an HIV negative to an HIV positive status, respectively. The implicated manufacturers reportedly took legal actions against the discovered counterfeiters, alerted impacted pharmacies, and assisted them with removal of illegitimate drugs. However, communities' gradual awareness or lack thereof in regards to counterfeit HIV prevention and treatment medications is likely to result in speculation about how many consumers took real versus fake medications, contributing to consumer distrust. This commentary provides details of a stakeholder meeting that took place with one of the leading manufacturers of HIV treatment and prevention medications to query its responses to counterfeit medications identified among its available product supplies in pharmacies. This manuscript also recommends to manufacturers ways to augment their communication strategies to communities if similar medicinal breaches occurred in the future.

Counterfeit medicines: relevance, consequences and strategies to combat the global crisis

Abstract Counterfeiting of medicines, also known as "falsification" or "adulteration", is the process in which the identity, origin, or history of genuine medicines are intentionally modified. Currently, counterfeit medicines are a global crisis that affects and is mostly caused by developing countries in Asia, Africa and Latin America. These countries lack strict law enforcement against this practice and have low-income populations with medicinal needs. Lately, the crisis has escalated, impacting developed countries as well, e.g., the US and the EU, mainly via the Internet. Despite this extension, some current laws aim to control and minimize the crisis' magnitude. Falsification of medicines maintains an illegitimate supply chain that is connected to the legitimate one, both of which are extremely complex, making such falsification difficult to control. Furthermore, political and economic causes are related to the crisis' hasty growth, causing serious consequences for individuals and public health, as well as for the economy of different countries. Recently, organizations, technologies and initiatives have been created to overcome the situation. Nevertheless, the development of more effective measures that could aggregate all the existing strategies into a large functioning network could help prevent the acquisition of counterfeit medicines and create awareness among the general population.

Cenário da falsificação de medicamentos no Brasil entre os anos de 2015 e 2022 / Scenario of drug counterfeiting in Brazil between 2015 and 2022

A falsificação de medicamentos é uma prática criminosa frequente em situações de alta demanda, carência de produtos e preços elevados no mercado, gerando muitos riscos à saúde da população. Objetivo: Estabelecer o panorama da falsificação de medicamentos no Brasil entre os anos de 2015 e 2022. Método: Trata-se de um estudo descritivo e retrospectivo dos registros de apreensão de medicamentos com indícios de falsificação, disponibilizados pela Agência Nacional de Vigilância Sanitária. Resultados: 30 fármacos diferentes foram mencionados nos registros de falsificação do período estudado, com predomínio de medicamentos biológicos e controlados e das formas farmacêuticas de via parenteral. Os fármacos que apresentaram mais registros de falsificação foram somatropina, imunoglobulina, sofosbuvir/ledispavir, eculizumabe e defibrotida. Conclusão: Por muitos anos, a falsificação de medicamentos no Brasil foi caracterizada principalmente por estimulantes sexuais masculinos, anabolizantes e anorexígenos. Entretanto, nos últimos anos, os medicamentos de alto custo destinados ao tratamento de doenças crônicas e raras se sobressaíram. Este cenário pode estar relacionado a diversos fatores, como gravidade das doenças, avanços das terapias medicamentosas, elevada lucratividade, falta de acesso aos medicamentos e dificuldades sociais e econômicas associadas à pandemia da doença por coronavírus 2019 (COVID-19)

Drug counterfeiting is a common criminal practice in situations of high demand, lack of products and high market prices, which generates risks to the health of the population. Objective: To establish an overview of drug counterfeiting in Brazil between 2015 and 2022. Method: This is a descriptive and retrospective study of data on drugs arrest with evidence of counterfeiting made available by the Brazilian Health Surveillance Agency. Results: 30 different drugs were mentioned in counterfeiting records for the period studied with a predominance of biopharmaceuticals and controlled substances, and parenteral pharmaceutical forms. The drugs with the most falsification records were somatropin, immunoglobulin, sofosbuvir/ledispavir, eculizumab and defibrotide. Conclusion: For many years, drug counterfeiting in Brazil was mainly characterized by male sexual stimulants, anabolic steroids, and anorectic. However, high-cost drugs for treating chronic and rare diseases have recently gained prominence. This scenario may be related to several factors, such as the severity of the diseases, advances in drug therapies, high profitability, lack of access to drugs, and social and economic difficulties associated with the coronavirus disease 2019 (COVID-19) pandemic

Assessment of the Quality of Injectable Antibiotics in Benin.

Substandard and falsified medicines are an enormous threat to global health. Poor quality antibiotic preparations contribute to the development of antimicrobial resistance. In surgery, where the occurrence of healthcare-associated infections is high, healthcare teams need to rely on the quality of antibiotic prophylaxis to prevent infections. We assessed the quality of antibiotics used for surgical infection prophylaxis in Benin. Thirty-three samples were collected from six hospitals located in various departments in Benin. The antibiotics (powders for injection: amoxicillin + clavulanic acid, ampicillin, ceftriaxone; solutions for injection: ciprofloxacin, gentamicin, metronidazole) were assessed using visual inspection, pharmacotechnical tests (including uniformity of mass, pH measure, sterility test, and active pharmaceutical ingredient identification), and assay tests (including a simple analytical method thin layer chromatography) and complex analytical techniques (ultraviolet-visible spectrophotometry, high-performance liquid chromatography-diode-array detection, conductometry). Because the material needed for the methods recommended by the pharmacopeias to assess the dosage of gentamicin was not available, we developed and validated a conductometry method. Results showed that 97% (n = 32) of the samples passed visual inspection; 100% (n = 33) of the samples passed the pharmacotechnical tests, identification of active ingredients, and sterility test; 88% (n = 29) passed the test for percentage of active pharmaceutical ingredients. Overall, 15% of the samples did not pass the quality test (3% on visual inspection and 12% for excess active ingredients). Although most of the samples passed the quality tests, it appears important to perform routine quality control for intravenous medicines.

The plague of unexpected drug recalls and the pandemic of falsified medications in cardiovascular medicine as a threat to patient safety and global public health: A brief review.

Valsartan, losartan, and irbesartan, are widely used in the treatment strategies of cardiovascular medicine diseases, including hypertension and heart failure. Recently, many formulations for the aforementioned diseases contained active pharmaceutical ingredients and had been abruptly recalled from the market due to safety concerns mainly associated with unwanted impurities - nitrosamines, which are highly carcinogenic substances accidentally produced during manufacturing. Along with cardiovascular medications, formulations containing ranitidine were also recalled from the market. This poses a particular threat to public health due to the non-prescription status of these drugs. Regulatory authorities, including the Food and Drug Administration and European Medicines Agency among others, have taken action to minimize patient risk and improve the manufacturing quality as well as re-checking current guidelines and recommendations. While these steps are necessary to avoid further recalls, authorities should remember the growing concerns of patients regarding the safety and efficacy of pharmacotherapy. Apart from the genuine manufacturing mistakes mentioned above, falsified and counterfeit medications should be at the heart of global attention. The lack of a well-accepted definition of falsified/counterfeit medications has impeded political and scientific efforts to mitigate risk of this phenomenon. Falsified Medicines Directive should be considered the most pivotal legislation recently enacted to harmonize international cooperation. In summary, one should remember that only international and direct collaboration between patients, stakeholders, and authorities be considered a remedy for a pandemic of falsified medicines and plague of unexpected recalls due to safety concerns.

Tadalafil and Sildenafil illicit association: Stability- indicating HPLC method, photodegradation kinetic and toxicological studies

Abstract The illicit market of counterfeit medicines containing sildenafil and tadalafil has been causing serious public health problems. Thus, further studies on this illicit association are needed. A stability-indicating HPLC method was developed for simultaneous determination of tadalafil (TAD) and sildenafil (SIL) using a C18 column (250 x 4.6 mm, 5 µm). Detection was achieved at 284 nm, for TAD, and 292 nm, for SIL. The method was considered to be specific, linear, precise, accurate, robust, and sensitive. In the photodegradation kinetic studies, the drugs showed a first-order reaction rate when isolated, and zero-order when associated. Toxicological assays demonstrated that the photodegraded drugs decreased cell viability in compared to non- degraded drugs, suggesting cytotoxic activity. Additional, mutagenic activity was not observed under the tested conditions. Photodegraded drugs, in association, depicted DNA damage index, suggesting genotoxic effects. The obtained results will be able to support the forensic intelligence laboratories, as well as to alert the population about the risk inherent to consuming counterfeit products.

Substandard Cisplatin Found While Screening the Quality of Anticancer Drugs From Addis Ababa, Ethiopia.

PURPOSE: A postmarket evaluation of chemotherapy dosage forms in Ethiopia was conducted to test the accuracy of the chemoPAD, a paper analytical device for drug quality screening. MATERIALS AND METHODS: In September of 2018 in Addis Ababa, Ethiopia, 41 anticancer drug dosage forms (representing 4 active ingredients, 5 brands, and 7 lot numbers) were collected and were rapidly screened for quality using a chemotherapy paper analytical device (chemoPAD). Confirmatory analysis via high performance liquid chromatography was conducted. RESULTS: The chemoPAD showed that the correct active pharmaceutical ingredient was present in doxorubicin, methotrexate, and oxaliplatin injectable dosage forms. However, 11 of 20 cisplatin samples failed the screening test. Confirmatory assay by high-performance liquid chromatography showed that all 20 cisplatin samples-comprising three lot numbers of a product stated to be Cisteen-were substandard, containing on average 54% ± 6% of the stated cisplatin content. Inductively coupled plasma optical emission spectroscopy analysis of five representative samples found 57% to 71% of the platinum that should have been present. The sensitivity of the chemoPAD for detection of falsified products could not be measured (as none were present in these samples), but the selectivity was 100% (no false positives). The sensitivity for detection of substandard products was 55%, and the selectivity was 100% (no false positives). CONCLUSION: Although instrumental analysis by pharmacopeia methods must remain the gold standard for assessing overall drug quality, these methods are time consuming and patients could be exposed to a bad-quality drug while clinical workers wait for testing to be performed. The chemoPAD technology could allow clinicians to check at the point of use for serious problems in the quality of chemotherapy drugs on a weekly or monthly schedule.

Experiences With Counterfeit Aesthetic Medical Devices and Injectables: A National Survey.

BACKGROUND: Counterfeit medical devices and injectables have recently garnered interest in the field of aesthetics. Unlike their original counterparts, these counterfeit products have neither been tested nor verified using certified quality control measures. OBJECTIVE: Our study investigated the pervasiveness of counterfeit products in the field as well as the experiences and attitudes of practitioners. MATERIALS AND METHODS: An online survey was distributed to current members of the American Society for Dermatologic Surgery (ASDS) and the American Society for Laser Medicine and Surgery (ASLMS). RESULTS: For medical devices, 37.4% have encountered counterfeits and 20.1% have experienced patients with adverse events from them. For injectables, 41.1% have encountered counterfeits and 39.7% have experienced patients with adverse events from them. Compared with their original, most respondents believe that counterfeits are worse in terms of reliability, safety, and effectiveness. The majority also believe that counterfeits are either very or extremely endangering to patient safety. CONCLUSION: Counterfeit medical devices and injectables are not uncommonly encountered. Overall, practitioners believe counterfeits are endangering patient safety and result in adverse events and think that either stricter rules and regulations or better enforcement of existing regulations is necessary.

Facing internet fake-medicine and web para-pharmacy in the total absence of official recommendations from medical societies.

PURPOSE: Internet fake information, parapharmacy and counterfeit drugs are a market of hundreds of billion dollars. Misleading internet data decrease patients' compliance to medical care, promote use of questionable and detrimental practices, and jeopardize patient outcome. This is particularly harmful among cancer patients, especially when pain and nutritional aspects are considered. Provision of Web recommendations for the general audience (patients, relatives, general population) from official medical-providers might be useful to outweigh the detrimental internet information produced by non-medical providers. METHODS: 370 oncology and anesthesiology related societies were analyzed. Our objective was to evaluate the magnitude of web-recommendation for cancer cachexia and cancer pain for the general audience provided by official medical organizations' web sites at global level. RESULTS: Magnitude of web-recommendations at global level was surprisingly scant both for coverage and consistency. Seven official medical societies provided updated web-recommendation for cancer cachexia to their patients/family members, and 15 for cancer pain. Scantiness was unrelated by continent, developmental index, oncology tradition, economic-geographic area and society type scrutinized. CONCLUSIONS: Patients need expert advice when exposed to fake internet information largely dominated by paramedical market profits. In this era of "new media" the patients' net-education represents a new major educational challenge for medical societies.

Falsification of biotechnology drugs: current dangers and/or future disasters?

Falsified medical products have become a global threat since they were first mentioned to the general public at the conference of experts on the rational use of drugs organized by the world health organization (WHO) in 1985. Today, official estimates of the annual death toll due to falsified medical products range between two hundred thousand and one million. Although the extent of this global problem is the most significant in the developing world, an increasing number of reports have demonstrated the presence of a substantial (black) market for falsified medical products in the developed world. In recent years, also biotechnology drugs (synthetic peptide drugs and protein drugs) have been reported to be prone for falsifications. Next to the traditional doping related substances and image-enhancing polypeptides (e.g., human growth hormone, melanotan II) also essential medicines such as insulin, oxytocin and monoclonal antibodies have been falsified. The danger regarding the use of these falsified polypeptide drugs lies in the fact that end-users have no guarantee of the safety and efficacy of these preparations. Multiple reports have namely described the presence of the wrong active pharmaceutical ingredient (API), the wrong dosage or the absence of the API. Additionally, adverse health effects have been reported in the past due to toxic contaminations and product or process related impurities. Moreover, also unauthorized polypeptides or polypeptides which failed clinical trials or are still subject of clinical or pre-clinical assessments have been found in seizures of regulatory agencies. It stands to reason that regulatory agencies and analytical laboratories handling falsified biotechnology drugs have stepped up efforts to counter these grievous practices. The analysis of these falsified polypeptides and putative impurities is however not always straightforward. Often (bio)analytical laboratories have to resort to a combination of electrophoretic techniques, immunological assays and mass spectrometry based approaches to merely identify the content of seized samples. In addition, the difference in size (peptide vs proteins vs monoclonal antibodies), complexity (e.g., isoforms, glycosylations) and different synthesis techniques (chemical synthesis, recombinant expression, native protein isolation) result in a wide range of putative health risks. This review therefore aims to provide a brief overview of the genuine biotherapeutics present on the market and their quality prerequisites. Next, we describe the identification strategy utilised by our lab to identify the API in falsified biotherapeutics, followed by a discussion of the putative hazards due to impurities and contaminations that were found or could be encountered in falsified biotherapeutics. Finally, we terminate with an educational prediction of what may happen in the future and possible ways to counteract putative future disasters.

Oncology drugs in the crosshairs of pharmaceutical crime.

Oncology drugs clearly have become a target for pharmaceutical crime. In 2016, falsified oncology drugs ranked fifth in the most commonly falsified drug category among the reports received by the Pharmaceutical Security Institute. Although the prevalence of illicit oncology drugs in the legal supply chains appears to be small, these drugs are difficult to detect, particularly in clinical practice. Forthcoming countermeasures to detect illicit drugs in high-income countries include compulsory antitampering devices and product verification technology for a risk-based selection of medicines. Health-care professionals must implement these new procedures into their workflow and remain vigilant about those medicines that are not selected. Although countermeasures should firmly tighten supply chain security, there are concerns about how quickly pharmaceutical crime will adapt to these protections. Because patients and health-care professionals have shown a lenient attitude towards purchasing medicines from unreliable sources, measures against the highly accessible illegal medicine supply chain remain necessary. To improve detectability in clinical practice, reporting of ineffectiveness and unusual drug effects as adverse events or adverse drug reactions is essential.

[Current cases of falsified medicinal products within the competence of the Federal Institute for Drugs and Medical Devices (BfArM) : Case studies and extent]. / Aktuelle Fälschungsfälle bei Arzneimitteln in der Zuständigkeit des Bundesinstituts für Arzneimittel und Medizinprodukte (BfArM) : Fallbeispiele und Ausmaß.

The nature of a falsification of a medicinal product can vary a lot. Therefore the means to detect them and the potential risk to patient safety can also be very different. The whole range of falsification will be described using observed cases from the Federal Institute for Drugs and Medical Devices (BfArM).Based on the relatively low number of detected cases of falsified medicines, the legal supply chain can still be regarded as safe. It has to be assumed that in the illegal supply chain, e. g. illegal internet trade, the majority of the offered medicinal products are not only falsifications due to illegal trade but because they are completely falsified. Therefore there is an especially high risk for the consumer to be harmed by medicinal products that do not fulfil the required specifications.The trend indicates that increased efforts will be necessary to keep the legal supply chain safe and to contain illegal trade with falsifications. The higher federal authorities BfArM, PEI and BVL are involved in this task by coordinating and ensuring the flow of information to the concerned authorities and stakeholders as well as informing the public. Increased efforts are also necessary due to the rising involvement of organised crime in the falsification of medicinal products. A package of measures was enacted with the Falsified Medicines Directive 2011/62/EU to protect the legal supply chain from falsified medicinal products.

[The Herceptin® case : A case of falsification of medicinal products to a greater extent]. / Der Herceptin®-Fall : Ein Fälschungsfall von Arzneimitteln größeren Ausmaßes.

Falsified medicines are a raising problem for the German drug market. The complex distribution channels across the European market facilitates the introduction of falsified and stolen medicines into the legal supply chain and may pose a risk for patients. The "Herceptin® case" from 2014 of falsified medicines of Italian origin demonstrates how complex distribution systems have been misused by criminal organizations in order to introduce stolen and thus falsified medicines via the parallel trade into the market, and which measures the authorities and the parallel-traders in the national and European network have taken to ensure patient safety. Falsified medicines will continue to be a problem in the future, so new monitoring systems have to be established and effectively used for prevention. The introduction of the EU-wide serialisation system in February 2019 is therefore intended to identify falsified drugs and to prevent the further trade as well as the expenditure to the patient. Furthermore, the maintenance and intensification of the cooperation between all EU authorities involved remains indispensable to close gateways in the distribution system for falsified medicines and to minimise the risk to the population.
