RESUMO
INTRODUCTION: Antimicrobial resistance (AMR) is a global concern. Currently, the greatest mortality due to AMR is in Africa. A key driver continues to be high levels of dispensing of antibiotics without a prescription. AREAS COVERED: A need to document current rates of dispensing, their rationale and potential ways forward including antimicrobial stewardship programmes (ASPs). A narrative review was undertaken. The highest rates of antibiotic purchasing were in Eritrea (up to 89.2% of antibiotics dispensed), Ethiopia (up to 87.9%), Nigeria (up to 86.5%), Tanzania (up to 92.3%) and Zambia (up to 100% of pharmacies dispensing antibiotics without a prescription). However, considerable variation was seen with no dispensing in a minority of countries and situations. Key drivers of self-purchasing included high co-payment levels for physician consultations and antibiotic costs, travel costs, convenience of pharmacies, patient requests, limited knowledge of antibiotics and AMR and weak enforcement. ASPs have been introduced in some African countries along with quality targets to reduce inappropriate dispensing, centering on educating pharmacists and patients. EXPERT OPINION: ASP activities need accelerating among community pharmacies alongside quality targets, with greater monitoring of pharmacists' activities to reduce inappropriate dispensing. Such activities, alongside educating patients and healthcare professionals, should enhance appropriate dispensing of antibiotics and reduce AMR.

OBJECTIVE: Measures are ongoing to prevent the spread of COVID-19 and treat it with medicines and personal protective equipment (PPE). However, there has been considerable controversy surrounding treatments such as hydroxychloroquine with misinformation fuelling prices hikes and suicides. Shortages have also appreciably increased costs of PPE, potentially catastrophic among lower- and middle-income countries such as Nigeria with high copayment levels. Consequently, a need to investigate changes in availability, utilization, and prices of relevant medicines and PPE during the pandemic in Nigeria. METHODS: Exploratory study among community pharmacists with a survey tool comprising four sections including questions on changes in consumption, prices, and shortages of medicines and PPE from the beginning of March 2020 to the end of June 2020. In addition, suggestions from community pharmacists and co-authors on ways to reduce misinformation. FINDINGS: 30 out of 34 pharmacists participated giving a response rate of 88.2%. Significant increases were seen (3-fold or more increase) in the consumption of hydroxychloroquine (100%), vitamins/immune boosters (96.7%) and antibiotics (46.7%) as well as PPE (100%). Considerable price increases (50% increase or greater) also seen for antimalarials (96.7%), antibiotics (93.3%), vitamins/immune boosters (66.7%), and PPE (100%). Shortages are also seen for hydroxychloroquine and vitamins/immune boosters but most severe for PPE (80% of pharmacies). CONCLUSION: Encouraging to see increases in the utilization of vitamins/immune boosters and PPE. However, a considerable increase in the utilization and prices of antimicrobials is a concern that needs addressing including misinformation. Community pharmacists have a key role in providing evidence-based advice and helping moderate prices.
RESUMO
Introduction: There are growing concerns among European health authorities regarding increasing prices for new cancer medicines, prices not necessarily linked to health gain and the implications for the sustainability of their healthcare systems.Areas covered: Narrative discussion principally among payers and their advisers regarding potential approaches to the pricing of new cancer medicines.Expert opinion: A number of potential pricing approaches are discussed including minimum effectiveness levels for new cancer medicines, managed entry agreements, multicriteria decision analyses (MCDAs), differential/tiered pricing, fair pricing models, amortization models as well as de-linkage models. We are likely to see a growth in alternative pricing deliberations in view of ongoing challenges. These include the considerable number of new oncology medicines in development including new gene therapies, new oncology medicines being launched with uncertainty regarding their value, and continued high prices coupled with the extent of confidential discounts for reimbursement. However, balanced against the need for new cancer medicines. This will lead to greater scrutiny over the prices of patent oncology medicines as more standard medicines lose their patent, calls for greater transparency as well as new models including amortization models. We will be monitoring these developments.

Background: Countries across Africa and Asia have introduced a variety of measures to prevent and treat COVID-19 with medicines and personal protective equipment (PPE). However, there has been considerable controversy surrounding some treatments including hydroxychloroquine where the initial hype and misinformation led to shortages, price rises and suicides. Price rises and shortages were also seen for PPE. Such activities can have catastrophic consequences especially in countries with high co-payment levels. Consequently, there is a need to investigate this further. Objective: Assess changes in utilisation, prices, and shortages of pertinent medicines and PPE among African and Asian countries since the start of pandemic. Our approach: Data gathering among community pharmacists to assess changes in patterns from the beginning of March until principally the end of May 2020. In addition, suggestions on ways to reduce misinformation. Results: One hundred and thirty one pharmacists took part building on the earlier studies across Asia. There were increases in the utilisation of principally antimalarials (hydroxychloroquine) and antibiotics (azithromycin) especially in Nigeria and Ghana. There were limited changes in Namibia and Vietnam reflecting current initiatives to reduce inappropriate prescribing and dispensing of antimicrobials. Encouragingly, there was increased use of vitamins/immune boosters and PPE across the countries where documented. In addition, generally limited change in the utilisation of herbal medicines. However, shortages have resulted in appreciable price increases in some countries although moderated in others through government initiatives. Suggestions in Namibia going forward included better planning and educating patients. Conclusion: Encouraging to see increases in the utilisation of vitamins/immune boosters and PPE. However, concerns with increased utilisation of antimicrobials needs addressing alongside misinformation, unintended consequences from the pandemic and any appreciable price rises. Community pharmacists and patient organisations can play key roles in providing evidence-based advice, helping moderate prices through improved stock management, and helping address unintended consequences of the pandemic.
RESUMO
INTRODUCTION: The potentials of Africa for growth and economic transformation through science remains challenging because of existing gaps in knowledge and infrastructure. The Africa Pharmacological Science Gateway project and the Medicines Utilization Research in Africa Group seek to meet the research needs of African pharmacologists. This study aimed at identifying priority needs that might be met by access to information and tools through e-infrastructure. METHODS: A web-based cross-sectional study among 472 members of pharmacological societies in Africa to obtain information on their research interests and skills, available resources, needs, and knowledge gaps. Descriptive analyses were done. RESULTS: A total of 118 responses from 13 countries were received, mostly from Nigeria (48.3%) and South Africa (21.3%). Respondents had wide ranges of research interests predominantly in drug utilization research. The desired resources included drug utilization research training and tools, pharmacokinetics and pharmacometrics modeling training and tools, drug-drug interaction and medicine prices resources, statistical analysis resources, access to journals, training in specific laboratory techniques, equipment and funding for research-related activities. CONCLUSIONS: Key areas of needs not currently provided by the African Pharmacological Science Gateway e-infrastructure were identified to guide the further provision of resources on the e-infrastructure and potentially enhance research capacity within the continent.

OBJECTIVES: The problem of antimicrobial resistance (AMR) has assumed pandemic dimensions especially among low-and middle-income countries such as Nigeria. Irrational use of currently available antimicrobial agents is a major contributory factor. There remains a paucity of documented information on the determinants of antibiotic prescribing among physicians in Nigeria to guide future strategies to reduce AMR. This study therefore aimed to investigate the patterns and determinants of antibiotic prescribing among doctors in a tertiary hospital in Nigeria as the first step to improve future antibiotic use in hospitals. METHODS: A cross-sectional survey of the determinants of antibiotic prescribing among doctors in the Lagos State University Teaching Hospital, Ikeja, was performed using a structured questionnaire. Information was obtained about the doctors and the factors determining their prescription of antibiotics. The results were summarized using descriptive statistics with Statistical Package for Social Science. RESULTS: Ninety-eight respondents were studied with a mean age of 36.24(9.01) years, a mean duration of practice of 10.68(9.25) years, and mainly males (64.3%). Ninety-seven percent prescribe antibiotics frequently, mostly based on clinical judgment and experience with rare laboratory supports. Factors of cost, drug availability, and information from pharmaceutical representatives influenced antibiotic prescribing. There were indications of nonexistence or nonfunctional institutional policies and guidelines regarding antimicrobial therapies. CONCLUSION: There is an urgent need to institute evidence-based institutional policies and guidelines for improving antimicrobial use among hospitals in Nigeria. This is already being followed up.

OBJECTIVE: Pharmaceutical companies spend significant amount of resources on promotion influencing the prescribing behavior of physicians. Drug promotion can negatively impact on rational prescribing, which may adversely affect the quality of patient care. However, little is known about these activities in Nigeria as the most populous country in Africa. We therefore aimed to explore the nature of encounters between Nigerian physicians and pharmaceutical sales representatives (PSRs), and how these encounters influence prescribing habits. METHODS: Cross-sectional questionnaire-based study conducted among practicing physicians working in tertiary hospitals in four regions of Nigeria. RESULTS: 176 questionnaires were completed. 154 respondents (87.5%) had medicines promoted to them in the previous three months, with most encounters taking place in outpatients' clinics (60.2%), clinical meetings (46%) and new medicine launches (17.6%). Information about potential adverse effects and drug interactions was provided in 41.5%, and 27.3% of cases, respectively. Food, in the form of lunch or dinner, was the most common form of incentive (70.5%) given to physicians during promotional activities. 61% of physicians felt motivated to prescribe the drug promoted to them, with the quality of information provided being the driving factor. Most physicians (64.8%) would agree to some form of regulation of the relationship between medical doctors and the pharmaceutical industry. CONCLUSION: Interaction between PSRs and physicians is a regular occurrence in Nigeria, influencing prescribing practices. Meals and cheap gifts were the most common items offered to physicians during their encounters with PSRs. The need for some form of regulation by professional organizations and the government was expressed by most respondents to address current concerns.

Generic medicines have the same efficacy and safety as originators at lower prices; however, there are concerns with their utilization in Nigeria. Objective was to evaluate physicians' understanding and perception of generics. A questionnaire was administered among physicians working in tertiary healthcare facilities in four geo-political regions of Nigeria. Questionnaire response was 74.3% (191/257) among mainly males (85.9%). The mean knowledge score regarding generics was 5.3 (maximum of 9) with 36.6%, 36.1% and 27.2% having poor, average and good knowledge respectively. Cross-tabulation showed statistical significance (p = 0.047) with the duration of practice but not with position, subspecialty or sex. The majority of respondents did not believe that generic medicines are of lower quality than branded medicines. Therapeutic failure was a major concern in 82.7%, potentially discouraging the prescribing of generics, and a majority (63.9%) did not support generic substitution by pharmacists. Knowledge gaps were identified especially with the perception of generics, which need to be addressed.
