RESUMO

Prescription drug costs within oncology remain a challenge for many patients with cancer. The Mark Cuban Cost Plus Drug Company (MCCPDC) launched in 2022, aiming to provide transparently priced medications at reduced costs. In this study, we sought to describe the potential impact of MCCPDC on Medicare Part-D oncology spending related to cancer-directed (n = 7) and supportive care (n = 26) drugs. We extracted data for drug-specific Part-D claims and spending for 2021. Using 90-count purchases from MCCPDC, we found potential Part-D savings of $857.8 million (91% savings) across the 7 cancer-directed drugs and $28.7 million (67% savings) across 21/26 (5/26 did not demonstrate savings) supportive care drugs. Collectively, our findings support that alternative purchasing models like MCCPDC may promote substantial health care savings.

RESUMO

BACKGROUND: US adults often overpay for generic prescription medications, which can lead to medication nonadherence that negatively impacts cardiovascular outcomes. As a result, new direct-to-consumer online medication services are growing in popularity nationwide. Amazon recently launched a $5/month direct-to-consumer medication subscription service (Amazon RxPass), but it is unclear how many US adults could save on out-of-pocket drug costs by using this new service. OBJECTIVES: To estimate out-of-pocket savings on generic prescription medications achievable through Amazon's new direct-to-consumer subscription medication service for adults with cardiovascular risk factors and/or conditions. METHODS: Cross-sectional study of adults 18-64 years in the 2019 Medical Expenditure Panel Survey. RESULTS: Of the 25,280,517 (SE ± 934,809) adults aged 18-64 years with cardiovascular risk factors or conditions who were prescribed at least 1 medication available in the Amazon RxPass formulary, only 6.4% (1,624,587 [SE ± 68,571]) would achieve savings. Among those achieving savings, the estimated average out-of-pocket savings would be $140 (SE ± $15.8) per person per year, amounting to a total savings of $228,093,570 (SE ± $26,117,241). In multivariable regression models, lack of insurance coverage (adjusted odds ratio [OR] 3.5, 95%CI 1.9-6.5) and being prescribed a greater number of RxPass-eligible medications (2-3 medications versus 1 medication: OR 5.6, 95%CI 3.0-10.3; 4+ medications: OR 21.8, 95%CI 10.7-44.3) were each associated with a higher likelihood of achieving out-of-pocket savings from RxPass. CONCLUSIONS: Changes to the pricing structure of Amazon's direct-to-consumer medication service are needed to expand out-of-pocket savings on generic medications to a larger segment of the working-age adults with cardiovascular risk factors and/or diseases.

RESUMO

The permeation of small molecules across biological membranes is a crucial process that lies at the heart of life. Permeation is involved not only in the maintenance of homeostasis at the cell level but also in the absorption and biodistribution of pharmacologically active substances throughout the human body. Membranes are formed by phospholipid bilayers that represent an energy barrier for permeating molecules. Crossing this energy barrier is assumed to be a singular event, and permeation has traditionally been described as a first-order kinetic process, proportional only to the concentration gradient of the permeating substance. For a given membrane composition, permeability was believed to be a unique property dependent only on the permeating molecule itself. We provide experimental evidence that this long-held view might not be entirely correct. Liposomes were used in copermeation experiments with a fluorescent probe, where simultaneous permeation of two substances occurred over a single phospholipid bilayer. Using an assay of six commonly prescribed drugs, we have found that the presence of a copermeant can either enhance or suppress the permeation rate of the probe molecule, often more than 2-fold in each direction. This can have significant consequences for the pharmacokinetics and bioavailability of commonly prescribed drugs when used in combination and provide new insight into so-far unexplained drug-drug interactions as well as changing the perspective on how new drug candidates are evaluated and tested.

RESUMO

BACKGROUND: Medication use during pregnancy has increased in the United States despite the lack of safety data for many medications. OBJECTIVE: This study aimed to inform research priorities by examining trends in medication use during pregnancy and identifying gaps in safety information on the most commonly prescribed medications. STUDY DESIGN: We identified population-based cohorts of commercially (MarketScan 2011-2020) and publicly (Medicaid Analytic eXtract/Transformed Medicaid Statistical Information System Analytic Files 2011-2018) insured pregnancies ending in live birth from 2 health care utilization databases. Medication use was based on filled prescriptions between the date of last menstrual period through delivery, as well as the period before the last menstrual period and during specific trimesters. We also included a cross-sectional representative sample of pregnancies ascertained by the National Health and Nutrition Examination Survey (2011-2020), with information on prescription medication use during the preceding month obtained through maternal interviews. Teratogen Information System was used to classify the available evidence on teratogenic risk. RESULTS: Among over 3 million pregnancies, the medications most commonly dispensed at any time during pregnancy were analgesics, antibiotics, and antiemetics. The top medications were ondansetron (16.8%), amoxicillin (13.5%), and azithromycin (12.4%) in MarketScan, nitrofurantoin (22.2%), acetaminophen (21.3%; mostly as part of acetaminophen-hydrocodone products), and ondansetron (19.5%) in Medicaid Analytic eXtract/Transformed Medicaid Statistical Information System Analytic Files, and levothyroxine (5.0%), sertraline (2.9%), and insulin (2.9%) in the National Health and Nutrition Examination Survey group. The most commonly dispensed suspected teratogens during the first trimester were antithyroid medications. The use of antidiabetic and psychotropic medications has continued to increase in the United States during the last decade, opioid dispensation has decreased by half, and antibiotics and antiemetics continue to be common. For one-quarter of medications, there is insufficient evidence available to characterize their safety profile in pregnancy. CONCLUSION: There is a need for more drug research in pregnant patients. Future research should focus on anti-infectives with high utilization and limited level of evidence on safety for use during pregnancy. Although lack of evidence is not evidence of safety concerns, it does not indicate risk either. In many instances, the benefits outweigh the risks when these medications are used clinically, and some of the medications with no proven safety may be necessary to treat patients.

RESUMO

AIMS: We aimed to examine trends in overall prescription medication use among patients with type 2 diabetes in the United States to provide insights for patient care. MATERIALS AND METHODS: We used nationally representative data from the National Health and Nutrition Examination Survey from 1999 to 2020 and included adult patients with type 2 diabetes. We examined the use of prescription drugs, overall and by drug class, polypharmacy (use of ≥5 medications), and number of medications attributed to specific classes. RESULTS: In the period 2015-2020, the mean patient age was 59.6 (51.0-70.0) years, with 46.8% (43.6-49.9) being female and 57.8% (52.8-62.8) being non-Hispanic White. Among 9489 adults with type 2 diabetes, the prevalence of polypharmacy was high and increased from 35.1% (31.6-38.6) in 1999-2002 to 47.2% (43.7-50.7) in 2003-2006, and further to 51.1% (48.3-53.9) in 2015-2020 (p for trend <0.001). Increasing trends of polypharmacy were found across all population subgroups and across the majority of therapeutic classes. Use of non-cardiometabolic medications was common. Among them, the most common were antidepressants (19.8%), proton pump inhibitors (19.0%) and analgesics (16.2%). Among patients with polypharmacy, approximately 40% of medication use was attributed to non-cardiometabolic medications. CONCLUSIONS: Prescription medication burden and complexity increased substantially among patients with type 2 diabetes, with more than 50% of patients with polypharmacy. Attention should be paid to this escalating medication use and regimen complexity, which requires multidisciplinary and coordinated care.

RESUMO

Changes in the dynamics of prescription drug markets have raised issues regarding whether the United States Bureau of Labor Statistics' (BLS') Prescription Drug Consumer Price Index (CPI-Rx) has adequately kept up with the evolving marketplace. The CPI-Rx limits its sampling frame to retail outpatient outlets and excludes prescription pharmaceuticals dispensed in non-retail settings such as hospitals, physician/clinic outpatient facilities, and nursing homes. Thus, the CPI-Rx overlooks the increasingly important specialty pharmaceuticals dispensed in non-retail settings, whose transactions are instead captured in the overall hospital and professional services component of the medical care CPI. Specialty drugs now account for about 55% of all U.S. drug spending, double the share of a decade earlier. To the extent specialty drug price growth differs from that of traditional pharmaceuticals, the CPI-Rx could provide an inaccurate measure of overall drug price inflation. We calculate a chained Laspeyres CPI using data from the Merative™ MarketScan® Databases for the years 2010-2019 and IQVIA-designated specialty drugs and offer evidence showing that by not sampling specialty drugs in non-retail settings, the CPI-Rx has understated overall U.S. prescription drug inflation by just under 75 basis points annually. We discuss implications for health care policy and suggest the BLS examine the feasibility of publishing an overall pharmaceutical price index incorporating both traditional and specialty pharmaceuticals dispensed in retail and non-retail settings.

RESUMO

The Medicare Part D program has been documented to increase the affordability and accessibility of drugs and improve the quality of prescription drug use; however, less is known about the equity impact of the Part D program on potentially inappropriate prescribing-specifically, incidences of polypharmacy and potentially inappropriate medication (PIM) use based on different racial/ethnic groups. Using a difference in the regression discontinuity design, we found that among Whites, Part D was associated with increases in polypharmacy and "broadly defined" PIM use, while the use of "always avoid" PIM remained unchanged. Conversely, Blacks and Hispanics reported no changes in such drug utilization patterns.

RESUMO

BACKGROUND: The Medicines Intelligence (MedIntel) Data Platform is an anonymised linked data resource designed to generate real-world evidence on prescribed medicine use, effectiveness, safety, costs and cost-effectiveness in Australia. RESULTS: The platform comprises Medicare-eligible people who are ≥18 years and residing in New South Wales (NSW), Australia, any time during 2005-2020, with linked administrative data on dispensed prescription medicines (Pharmaceutical Benefits Scheme), health service use (Medicare Benefits Schedule), emergency department visits (NSW Emergency Department Data Collection), hospitalisations (NSW Admitted Patient Data Collection) plus death (National Death Index) and cancer registrations (NSW Cancer Registry). Data are currently available to 2022, with approval to update the cohort and data collections annually. The platform includes 7.4 million unique people across all years, covering 36.9% of the Australian adult population; the overall population increased from 4.8 M in 2005 to 6.0 M in 2020. As of 1 January 2019 (the last pre-pandemic year), the cohort had a mean age of 48.7 years (51.1% female), with most people (4.4 M, 74.7%) residing in a major city. In 2019, 4.4 M people (73.3%) were dispensed a medicine, 1.2 M (20.5%) were hospitalised, 5.3 M (89.4%) had a GP or specialist appointment, and 54 003 people died. Anti-infectives were the most prevalent medicines dispensed to the cohort in 2019 (43.1%), followed by nervous system (32.2%) and cardiovascular system medicines (30.2%). CONCLUSION: The MedIntel Data Platform creates opportunities for national and international research collaborations and enables us to address contemporary clinically- and policy-relevant research questions about quality use of medicines and health outcomes in Australia and globally.

RESUMO

BACKGROUND: Osteoarthritis (OA) patients taking prescription opioids for pain are at increased risk of fall or fracture, and the concomitant use of interacting drugs may further increase the risk of these events. AIMS: To identify prescription opioid-related medication combinations associated with fall or fracture. MATERIALS & METHODS: We conducted a case-crossover-based screening of two administrative claims databases spanning 2003 through 2021. OA patients were aged 40 years or older with at least 365 days of continuous enrollment and 90 days of continuous prescription opioid use before their first eligible fall or fracture event. The primary analysis quantified the odds ratio (OR) between fall and non-opioid medications dispensed in the 90 days before the fall date after adjustment for prescription opioid dosage and confounding using a case-time-control design. A secondary analogous analysis evaluated medications associated with fracture. The false discovery rate (FDR) was used to account for multiple testing. RESULTS: We identified 41 693 OA patients who experienced a fall and 24 891 OA patients who experienced a fracture after at least 90 days of continuous opioid therapy. Top non-opioid medications by ascending p-value with OR > 1 for fall were meloxicam (OR 1.22, FDR = 0.08), metoprolol (OR 1.06, FDR >0.99), and celecoxib (OR 1.13, FDR > 0.99). Top non-opioid medications for fracture were losartan (OR 1.20, FDR = 0.80), alprazolam (OR 1.14, FDR > 0.99), and duloxetine (OR 1.12, FDR = 0.97). CONCLUSION: Clinicians may seek to monitor patients who are co-prescribed drugs that act on the central nervous system, especially in individuals with OA.

RESUMO

INTRODUCTION: Maternal demographics have evolved, and more women than ever enter pregnancy with preexisting comorbidity and with potentially complex medication exposure, including polypharmacy (concomitant intake of multiple medications). This study aims to describe the evolution of medication use in pregnancy in Denmark from 1998 to 2018 with special focus on polypharmacy, patterns of use, and underlying demographics. MATERIAL AND METHODS: A Danish nationwide historical registry study based on all clinically recognized pregnancies with a gestation ≥10 weeks between 1998 and 2018. Medication use was estimated by redemption of prescriptions during pregnancy. RESULTS: Among a total of 1 402 327 clinically recognized pregnancies, redemption of at least one prescription medication during pregnancy increased from 56.9% in 1998 to 63.3% in 2018, coinciding with an increased use of polypharmacy (from 24.8% in 1998 to 35.2% in 2018). The prevalence of pregnant women who used medications for chronic conditions increased more than the prevalence of women treated for occasional or short-time conditions. Redemption of one or multiple prescription medications during pregnancy was mostly seen among pregnant women ≥35 years of age. However, pregnant women <25 years old exhibited the largest increase in medication use during the study period. CONCLUSIONS: Medication use in general, and polypharmacy in particular, increased from 1998 to 2008, possibly as the result of an increased prevalence of pregnant women with chronic conditions requiring pharmacological treatment. Notably, a marked maternal age-based discrepancy in usage pattern was observed, highlighting the need for further research in this area. The rise in the prevalence of polypharmacy during pregnancy underscores the need for pharmacovigilance to monitor adverse effects. Future studies should investigate the patterns of polypharmacy and the accompanying maternal and fetal risks.

RESUMO

BACKGROUND: Adolescent athletes' values ​regarding health behaviors, including their attitudes toward doping, are largely derived from those of their parents. Therefore, clarifying the factors that affect parents' intentions regarding their children's medicine intake and nutrition can help elucidate the process of forming values ​​of healthy behaviors in young athletes. METHODS: Between March 8 and March 9, 2021, an online questionnaire survey was conducted via an Internet research company; data from 2,000 residents in Japan were collected. Participants were male and female residents aged 30-59 years with children in elementary or high school and belonging to sports clubs. The survey items included respondent's and child's basic information, respondent's health literacy, and level of sports in which the respondent and child were (or are) engaged. Respondents were also asked if they would like their children to receive prescription drugs, over-the-counter drugs, herbal medicines, vaccines, supplements, or energy drinks. Logistic regression analysis was performed to analyze the relationship between respondents' basic information and health literacy and their intention to receive prescription and over-the-counter drugs, herbal medicines, vaccines, supplements, and energy drinks. RESULTS: Higher parental health literacy was associated with higher children's willingness to receive prescription drugs (odds ratio [OR] = 1.025, 95% confidence interval [CI]: 1.016-1.035), over-the-counter drugs (OR = 1.012, 95% CI: 1.003-1.021), prescription herbal medicines (OR = 1.021, 95% CI: 1.021-1.030), over-the-counter herbal medicines (OR = 1.012, 95% CI: 1.003-1.021), and vaccines (OR = 1.025, 95% CI: 1.016-1.035). Conversely, the children's intention to receive energy drinks (OR = 0.990, 95% CI: 0.980-1.000) decreased significantly. As the child's athletic level increased, parents' willingness for their children to receive oral prescription medicines decreased (OR = 0.886, 95% CI: 0.791-0.992) and that to receive supplements (OR = 1.492, 95% CI: 1.330-1.673) and energy drinks significantly increased (OR = 1.480, 95% CI: 1.307-1.676). CONCLUSION: Health literacy of adolescent athletes' parents is associated with their children's willingness to receive medicines. Healthcare providers should counsel parents of adolescent athletes to allow their children to receive necessary drug treatments and prevent doping violations caused by supplement intake.

RESUMO

BACKGROUND: Rural-urban differences in health service use among persons with prevalent dementia are known. However, the extent of geographic differences in health service use over a long observation period, and prior to diagnosis, have not been sufficiently examined. The purpose of this study was to examine yearly rural-urban differences in the proportion of patients using health services, and the mean number of services, in the 5-year period before and 5-year period after a first diagnosis of dementia. METHODS: This population-based retrospective cohort study used linked administrative health data from the Canadian province of Saskatchewan to investigate the use of five health services [family physician (FP), specialist physician, hospital admission, all-type prescription drug dispensations, and short-term institutional care admission] each year from April 2008 to March 2019. Persons with dementia included 2,024 adults aged 65 years and older diagnosed from 1 April 2013 to 31 March 2014 (617 rural; 1,407 urban). Matching was performed 1:1 to persons without dementia on age group, sex, rural versus urban residence, geographic region, and comorbidity. Differences between rural and urban persons within the dementia and control cohorts were separately identified using the Z-score test for proportions (p < 0.05) and independent samples t-test for means (p < 0.05). RESULTS: Rural compared to urban persons with dementia had a lower average number of FP visits during 1-year and 2-year preindex and between 2-year and 4-year postindex (p < 0.05), a lower likelihood of at least one specialist visit and a lower average number of specialist visits during each year (p < 0.05), and a lower average number of all-type prescription drug dispensations for most of the 10-year study period (p < 0.05). Rural-urban differences were not observed in admission to hospital or short-term institutional care (p > 0.05 each year). CONCLUSIONS: This study identified important geographic differences in physician services and all-type prescription drugs before and after dementia diagnosis. Health system planners and educators must determine how to use existing resources and technological advances to support care for rural persons living with dementia.

RESUMO

BACKGROUND: Data from the social media platform X (formerly Twitter) can provide insights into the types of language that are used when discussing drug use. In past research using latent Dirichlet allocation (LDA), we found that tweets containing "street names" of prescription drugs were difficult to classify due to the similarity to other colloquialisms and lack of clarity over how the terms were used. Conversely, "brand name" references were more amenable to machine-driven categorization. OBJECTIVE: This study sought to use next-generation techniques (beyond LDA) from natural language processing to reprocess X data and automatically cluster groups of tweets into topics to differentiate between street- and brand-name data sets. We also aimed to analyze the differences in emotional valence between the 2 data sets to study the relationship between engagement on social media and sentiment. METHODS: We used the Twitter application programming interface to collect tweets that contained the street and brand name of a prescription drug within the tweet. Using BERTopic in combination with Uniform Manifold Approximation and Projection and k-means, we generated topics for the street-name corpus (n=170,618) and brand-name corpus (n=245,145). Valence Aware Dictionary and Sentiment Reasoner (VADER) scores were used to classify whether tweets within the topics had positive, negative, or neutral sentiments. Two different logistic regression classifiers were used to predict the sentiment label within each corpus. The first model used a tweet's engagement metrics and topic ID to predict the label, while the second model used those features in addition to the top 5000 tweets with the largest term-frequency-inverse document frequency score. RESULTS: Using BERTopic, we identified 40 topics for the street-name data set and 5 topics for the brand-name data set, which we generalized into 8 and 5 topics of discussion, respectively. Four of the general themes of discussion in the brand-name corpus referenced drug use, while 2 themes of discussion in the street-name corpus referenced drug use. From the VADER scores, we found that both corpora were inclined toward positive sentiment. Adding the vectorized tweet text increased the accuracy of our models by around 40% compared with the models that did not incorporate the tweet text in both corpora. CONCLUSIONS: BERTopic was able to classify tweets well. As with LDA, the discussion using brand names was more similar between tweets than the discussion using street names. VADER scores could only be logically applied to the brand-name corpus because of the high prevalence of non-drug-related topics in the street-name data. Brand-name tweets either discussed drugs positively or negatively, with few posts having a neutral emotionality. From our machine learning models, engagement alone was not enough to predict the sentiment label; the added context from the tweets was needed to understand the emotionality of a tweet.

RESUMO

Introduction: Haven is a student-run free clinic in New Haven, Connecticut, that serves more than 500 patients annually. Haven's pharmacy department helps patients obtain medications by providing discount coupons or medications from the clinic's in-house pharmacy, directly paying for medications at local pharmacies, and delivering medications to patients' homes. This study aimed to identify prescriptions that have the highest cost among Haven patients. Methods: Our sample consisted of all Haven patients who attended the clinic from March 2021 through March 2023. Patients were eligible to be seen at Haven if they were aged 18 to 65 years, lacked health insurance, and lived in New Haven. We determined the lowest cost of each medication prescribed to Haven patients by comparing prices among local pharmacies after applying a GoodRx discount. We defined expensive medication as more than $20 per prescription. We excluded medical supplies. Results: Of the 594 Haven patients in our sample, 64% (n = 378) required financial assistance and 22% (n = 129) were prescribed at least 1 expensive medication. Among 129 patients prescribed an expensive medication, the mean (SD) age was 45.0 (12.3) years; 65% were women, and 87% were Hispanic or Latino. Median (IQR) household annual income was $14,400 [$0-$24,000]. We identified 246 expensive medications; the median (IQR) price per prescription was $31.43 ($24.00-$52.02). The most frequently prescribed expensive medications were fluticasone propionate/salmeterol (accounting for 6% of all expensive medications), medroxyprogesterone acetate (6%), albuterol sulfate (5%), and rosuvastatin (5%). Conclusion: The average Haven patient has an income well below the federal poverty level, and many have chronic cardiovascular and respiratory conditions that require expensive medications. Future research should work toward making medications universally affordable.

RESUMO

BACKGROUND: People who use drugs experience pain at two to three times the rate of the general population and yet continue to face substantial barriers to accessing appropriate and adequate treatment for pain. In light of the overdose crisis and revised opioid prescribing guidelines, we sought to identify factors associated with being denied pain medication and longitudinally investigate denial rates among people who use drugs. METHODS: We used multivariable generalized estimating equations analyses to investigate factors associated with being denied pain medication among people who use drugs reporting pain in three prospective cohort studies in Vancouver, Canada. Analyses were restricted to study periods in which participants requested a prescription for pain from a healthcare provider. Descriptive statistics detail denial rates and actions taken by participants after being denied. RESULTS: Among 1168 participants who requested a prescription for pain between December 2012 and March 2020, the median age was 47 years and 63.0% were male. Among 4,179 six-month observation periods, 907 (21.7%) included a report of being denied requested pain medication. In multivariable analyses, age was negatively associated with prescription denial (adjusted odds ratio [AOR] = 0.98, 95% confidence interval [CI]:0.97-0.99), while self-managing pain (AOR = 2.48, 95%CI:2.04-3.00), experiencing a non-fatal overdose (AOR = 1.51, 95%CI:1.22-1.88), engagement in opioid agonist therapy (AOR = 1.32, 95%CI:1.09-1.61), and daily use of heroin or other unregulated opioids (AOR = 1.32, 95%CI:1.05-1.66) were positively associated with being denied. Common actions taken (n = 895) after denial were accessing the unregulated drug supply (53.5%), doing nothing (30.6%), and going to a different doctor/emergency room (6.1%). The period following the introduction of new prescribing guidelines was not associated with a change in denial rates. CONCLUSIONS: A substantial proportion of people who use drugs continue to be denied prescriptions for pain, with such denial associated with important substance use-related harms, including non-fatal overdose. Guidelines specific to the pharmaceutical management of pain among people who use drugs are needed.

RESUMO

BACKGROUND: Serotonin toxicity is a well-described phenomenon that is commonly attributed to a variety of drug-drug combinations. Some unregulated herbal supplements have been implicated in the onset of serotonin toxicity, however, there is currently minimal literature available on the potential for black cohosh to contribute to rhabdomyolysis and serotonin toxicity, in spite of its known serotonergic properties. CASE REPORT: A middle-aged woman presented to the emergency department with serotonin toxicity and rhabdomyolysis shortly after taking black cohosh supplements in the setting of long-term dual antidepressant use. The serotonin toxicity and rhabdomyolysis resolved with IV fluids, benzodiazepines, and discontinuation of the offending drugs. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Patients are sometimes not aware of how over-the-counter supplements might interact with their prescription medications. Female patients taking black cohosh to manage hot flashes and menopausal symptoms could be at risk for developing rhabdomyolysis and serotonin toxicity if they are also taking other serotonergic agents.

RESUMO

Importance: The Federal Trade Commission's (FTC) oversight role in the pharmaceutical market is critical to the health of patients and the health care system. This study characterized the FTC's policy on the pharmaceutical market in recent decades, identifying the types of actions it has favored, barriers it has faced, and authorities that remain untested. Objective: To review FTC legal actions in the pharmaceutical market from 2000-2022. Evidence Review: Legal actions were determined through manual review of search results from the FTC's online Legal Library as well as a 2023 FTC report on pharmaceutical actions. The alleged misconduct, type of legal action taken, timing, and outcome were collected from press releases, complaints, orders, and other legal documents. Findings: From 2000-2022, the FTC challenged 62 mergers, brought 22 enforcement actions against allegedly unlawful business practices, and made 1 rule related to pharmaceuticals. Alleged misconduct in enforcement actions involved anticompetitive settlements in patent litigation (n = 11), unilateral actions by brand manufacturers to delay generic competition (n = 6), noncompete agreements (n = 4), and monopolization (n = 3), with 10 outcomes involving monetary payment, totaling $1.6 billion. Of the 62 mergers the FTC challenged, 61 were allowed to continue, 58 after divesting certain drugs to third-party competitors. The FTC's reliance on drug divestitures decreased from 18 drugs per year from 2000-2017 to 4.3 per year from 2017-2023. Conclusions and Relevance: The FTC brought about 1 enforcement action and 3 merger actions per year against pharmaceutical manufacturers from 2000-2022, pursuing a small fraction of the estimated misconduct and consolidation in the pharmaceutical marketplace. Although the FTC faces substantial legal and practical limitations, important tools remain untested, including a rule defining "unfair methods of competition," that may allow it to more effectively prevent repetitive patterns of anticompetitive behavior.

RESUMO

Pharmacists and pharmacies are key drivers in the American marketplace. They serve as an endpoint of the pharmaceutical supply chain and are the dispensers of a range of consumer goods, some nonthreatening and others potentially harmful to public health. In adding pharmacies to the roster of consumerist locales in the postwar period, scholars might draw even deeper connections about the transformation of health, corporate medicine, and American economic power. To understand the interface of consumerism, corporatism, and health in postwar America, this article holds the postwar pharmacy as a key site of commodity exchange and business and positions it within the larger American firmament, paying attention to the design of pharmacies. In particular, the article will add to the knowledge about the tangible ways that medical and health care spaces are constructed, organized, and designed to best generate profits. Besides prescription medications, alcohol, tobacco, and sugar-rich products were also vital elements of the postwar pharmacy and will be featured in this article. What is more, this article focuses on a central debate between pharmacists during the postwar period about how pharmacies were shifting from the role of healer to that of a retailer - from a "conscientious guardian" to a "commercialized jungle" - in order to highlight how the public health role of pharmacies was undermined by industry pressures for profit. Based on unused corporate guides and manuals, company records, photographs, and management documents, this article will spotlight the underexplored interiority of pharmacies - the store's insides, processes of organization, and design features related to potentially habit-changing substances.

RESUMO

With the severe rapid aging in China, the health management system of elderly-related diseases is facing great challenges. Because of its various effects such as lipid-lowering, anti-inflammatory, and primary and sencondary prevension of atherosclerotic cardiovascular disease, etc, ω-3 fatty acids are increasingly being valued in the field of geriatric medicine. To further standardize the application of ω-3 fatty acid drugs in the field of geriatrics, initiated by the Chinese Medical Association Geriatrics Branch, based on the existing medical evidence and combined with the clinical practice of geriatrics in China, 12 recommendations were proposed, including the application of ω-3 fatty acids on cardiovascular diseases, chronic kidney disease, nervous system disease, respiratory system disease, sarcopenia, frailty, osteoporosis, tumor and autoimmune diseases, aiming to provide guidance for clinical decision-making in geriatric diseases.
