"Codeine Is My Helper": Misuse of and Dependence on Codeine-Containing Medicines in South Africa

Multi-modal neuroprotection of Argemone mexicana L. against Alzheimer's disease: In vitro and in silico study

Argemone mexicana L. is a medicinal plant, but its impact on Alzheimer's disease (AD) is right now undetermined. We intended to investigate the in-vitro anti-AD potential of leaves and flowers of A. mexicana methanol, ethanol, and ethyl extracts and to identify multi-modal anti-AD phytochemicals by computational approaches. Molecular docking of 196 phytochemicals identified three hit phytochemicals (protoberberine, protopine, and codeine) with higher binding affinity and multi-targeting ability toward AChE, BChE, BACE-1, and GSK-3β. Further MM-GBSA assays confirmed the integrity of these phytochemicals as the hit phytochemicals. However, these phytochemicals demonstrated favorable pharmacokinetics (PK) and drugable properties having no toxicity. Molecular dynamics simulations confirmed the binding strength of the hit phytoconstituents in the active pockets of AChE, BChE, BACE-1, and GSK-3β with multi-targeting inhibitory activities. All the extracts exhibited dose-dependent antioxidant and anti-cholinesterase activities supporting the in silico results in the context of oxidative stress and cholinergic pathways. Our results offer scientific validation of the anti-AD properties of Argemone mexicana L. and identified protoberberine, protopine, and codeine that could be used for the development of multi-modal inhibitors of AChE, BChE, BACE-1, and GSK-3β to combat AD. Additional in vivo validation is recommended to ensure a thorough assessment in the present research.

A scoping review on the availability and utilization of essential opioid analgesics in Sub-Saharan Africa

BACKGROUND

Management of acute, post-operative, and chronic pain requires access to and availability of opioids. While often oversupplied in high-income countries, significant shortages exist in low- and middle-income countries. We conducted a scoping review on availability and usage of opioids in Sub-Saharan Africa (SSA).

METHODS

The five-stage approach of Arksey and O'Malley (2005) was used. MEDLINE via PubMed, EMBASE, and SCOPUS were search and results categorized into themes: 1) Local/regional availability and supply, 2) Consumption patterns, 3) Legislation and policy, 4) Costs and financing, 5) Knowledge and cultural beliefs, and 6) Education and training.

RESULTS

6923 studies were identified from which 69 (1%) met inclusion criteria. Five key findings were: 1) Significant shortages exist, especially in rural areas, 2) Non-opioid analgesics commonly used as first-line acute pain management, 3) Barriers to market entry and bureaucratic processes prevent local production, 4) Significant knowledge gaps/myths exist amongst healthcare practitioners on opioid use, and 5) Continuous education and short courses will be critical.

CONCLUSIONS

Major challenges significantly limit availability and utilization of essential opioids in SSA. Reforms needed to upscale training and education, increase uptake by professionals, and increase market entry.

Suspected inappropriate use of prescription and non-prescription drugs among requesting customers: A Saudi community pharmacists' perspective

Background

Inappropriate use of medications is a global health concern, and this is attributed to the increased accessibility to prescription and non-prescription (over-the-counter) drugs at community pharmacies. We investigated the inappropriate use of prescription and non-prescription drugs in community pharmacies based on the perspectives of the community pharmacists in Saudi Arabia.

Methods

This was a questionnaire-based, cross-sectional survey which employed convenient sampling (snowball technique) to recruit participants. Being a licensed practicing pharmacist in a retail chain or an independent community pharmacy was the inclusion criteria. Participants were asked to report the drugs they suspected of being inappropriately used along with the frequency, age and gender of the suspected customers. Pharmacists were also asked to mention the action taken to limit inappropriate use at their pharmacy.

Results

A total of 397 community pharmacists completed the questionnaire (86.9 % response rate). 86.4% of the pharmacists suspected some level of abuse or misuse to have occurred. After receiving the questionnaire, the pharmacists reported suspected inappropriate use as encountered during the past three months. Cumulative inappropriate use was reported 1069 times (prescription drugs - 530; non-prescription drugs - 539). The top three inappropriately used prescription-drug categories were gabapentinoids (22.5%), antipsychotics (17.5%) and topical corticosteroids (12.1%). Among non-prescription drugs, cough products (33.2%) ranked first, followed by cold and flu products (29.5%) and first-generation antihistamines (10.8%). The cross tabulations revealed that being in the age range of 26-50 years and being a male was significantly associated (p < 0.001) with abuse/misuse of antipsychotics, antidepressants, gabapentinoids, cough products and first-generation antihistamines. Eye products (Bimatoprost) and skin products abuse/misuse had significant association with female gender (p < 0.001).

Conclusion

The results of our study provide crucial information to the healthcare authorities regarding the medications that can be inappropriately used at the community pharmacies in Saudi Arabia which necessitates implementation of stringent dispensing regulations. Educational programs can be implemented to increase the awareness among public regarding the harmful effects of inappropriate use of drugs.

Pattern of substance use and substance use disorder in adolescent learners at public secondary schools in Gaborone, Botswana

INTRODUCTION

Substance use amongst adolescents remains a global public health challenge. The potential negative health outcomes of substance use suggest the need to understand the pattern of use and the associated factors among adolescents. This study aimed to describe the prevalence of substance use, SUDs, and PD and the associated factors in adolescent learners at public schools in Gaborone, Botswana.

METHODS

A cross-sectional study was conducted at 13 public secondary schools in Gaborone among 742 students. Assessment tools included the World Health Organization drug questionnaire, DSM-5 interview for SUD, and the General Health Questionnaire-12.

RESULTS

The mean age (SD) of the participants was 15.26 (1.57) years, and there were more females (55.5%). Over two-fifths (44.6%) of learners reported psychoactive substance use in the past 12 months, and 31.5% meeting DSM 5 criteria for a SUD. Alcohol was the most used psychoactive substance (25.1%). Male gender (AOR = 1.94; 95% CI: 1.26-2.995), having a friend (AOR = 4.27; 95% CI: 2.68-6.78), or father (AOR = 1.87; 95% CI: 1.14-3.04), who uses substance, and higher levels of PD (AOR = 1.09; 95% CI: 1.03-1.17) remained significantly associated with SUD. Regular participation in religious activities negatively correlated with SUD (AOR = 0.61; 95% CI: 0.38-0.96).

CONCLUSION

The high prevalence of substance use and SUDs among in-school adolescents is concerning. Substance use programs need to include family-focused and religious-based therapy and youth empowerment in developing positive peer relationships. Also, they should be integrated with mental health screening to assess comorbid PD.

Misuse of Over the Counter and Prescription Only Medication by Adults Accessing Specialist Treatment Services in the UK: A Narrative Synthesis

Background

Concerns about the misuse of over the counter (OTC) and prescription only medication (POM) are due to their impact upon physical/mental wellbeing, drug interactions and drug-related deaths. Improving an understanding of the pattern of use by people accessing specialist substance misuse services (SMSs) should enable improvements to treatment provision.

Aim

To review the literature on the misuse of OTC/POM among adults accessing SMS, including the pattern of use, types of medication and associated characteristics.

Methods

This review is reported in line with PRISMA. The protocol has been registered on PROSPERO (CRD42020135216) and separately published. A search of Cochrane, OVID Medline, Pubmed, Scopus and Web of Science databases and grey literature was undertaken. Only English language publications outlining OTC/POM misuse by adults in receipt of psychological/pharmacological interventions for substance misuse were included. Two reviewers conducted the title, abstract and full-text reviews using predetermined selection criteria and a piloted data extraction form to ensure a consistent approach. A third reviewer resolved disagreements and the Mixed Methods Appraisal Tool assessed for bias. Ethical approval was not required.

Results

Thirteen studies with notable heterogeneity were included in the narrative synthesis after non-UK-based and ineligible publications were excluded, from the 143 potentially relevant papers. To reduce bias all studies were included in the analysis and GRADE-CERQual was applied. 'High confidence' was identified for all review findings, despite moderate methodological limitations. Antihistamine, benzodiazepine and opioid misuse was mentioned most frequently. Usage patterns and supply sources varied. Adverse consequences and polypharmacy are concerning. Withdrawal symptoms perpetuated misuse, often alongside illicit substance use, comorbid psychiatric/pain disorders and street drug shortages.

Conclusion

OTC/POM misuse is common amongst adults accessing SMS. A renewed approach to withdrawal management is required. The limited number of studies may impact on generalisability but allowed for a more detailed review. Restricting to UK studies improved relevance due to drug market variations and availability of medicines in different countries. Further UK-based research on OTC/POM misuse in SMS is needed to build upon the current paucity in the published literature.

'I Was Present but I Was Absent': Perceptions and Experiences of the Non-Medical Use of Prescription or over the Counter Medication among Employed South African Women

BACKGROUND

The need for workplace substance use prevention programmes globally and in South Africa is driven by the growing problem of substance use and the associated burden on the health and welfare of employees, their families and organizations. Substance use, which include the non-medical use of medications (both prescription and over-the counter), remains widespread and is a major cause of mortality and a risk factor for non-communicable diseases (NCDs).

METHOD

Twenty in-depth semi-structured qualitative interviews were conducted with employed women in treatment or shortly out of treatment for the non-medically indicated use of over the counter or/and prescription medications (NMIU). These interviews were conducted face-to face with women residing in the Western and Eastern Cape provinces of South Africa. Thematic analysis using NVIVO was used to analyse data collected.

RESULTS

The findings from this study suggest that previous use of legal or illegal substances and challenging life experiences underpin pathways to the non-medical use of over-the-counter and prescription medications among employed women. Factors found to contribute to misuse relate to a lack of understanding on risks, and health professional prescribing practices, while mitigators to harmful use were related to increased awareness and understanding harmful practices, the need for improved access and referral to specialist treatment as well as prevention programmes for women.

CONCLUSION

With the improved understanding of the issues surrounding the NMIU of over-the-counter and prescription medications among employed women, the need for interventions to prevent misuse and inadvertently dependency is highlighted.

Physician Perspectives on Codeine Accessibility, Patterns of Use, Misuse, and Dependence in Saudi Arabia

In Saudi Arabia, there are concerning rates of non-compliance with pharmaceutical regulations prohibiting the pharmacy dispensing of prescription-only medications without a physician prescription. This is the first study in the Middle East which examines physicians’ perceptions regarding misuse of codeine, listed as a narcotic, controlled, and prescription-only drug. The CODEMISUSED survey was adapted to the Saudi Arabian context and pilot tested, prior to cross-sectional administration to physicians in Riyadh, Jeddah, Abha, and Jazan (n = 105). Descriptive statistics (frequencies and percentage) present physician level of agreement, neutrality, and disagreement with statements regarding codeine prescribing, patient awareness and use, online and community pharmacy availability, and dependence. The study indicates concern by physicians regarding patient intentional use of codeine to enhance mood, misuse patterns, lack of awareness around habit-forming use and iatrogenic dependence, and sourcing via illegal dispensing. It underscores the imperatives to address pharmacy compliance with pharmaceutical regulatory controls, implement enhanced pharmacovigilance, and improve awareness around safe use.

A mixed-methods systematic review of the prevalence, reasons, associated harms and risk-reduction interventions of over-the-counter (OTC) medicines misuse, abuse and dependence in adults

Background

Over-the-counter (OTC) medicines are typically safe. However, there is evidence that OTC medicines can sometimes cause harm as a result of their misuse, abuse and dependence.

Aim of the review

To review the literature on OTC medicines misuse, abuse and dependence in adults and identify the implicated medicines, contributing factors, associated harms and risk-mitigating interventions.

Methods

Following PRISMA guidelines, electronic databases including Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, MEDLINE, PsycINFO Web of Science and Google Scholar were searched for peer-reviewed journal articles published in English between January 2011 and March 2019. Quantitative, qualitative and mixed-methods studies assessing aspects of misuse, abuse and dependence of OTC medicines in individuals aged 18 years or more were included. Studies that solely focused on adolescents only, doping in sports or abuse of OTC medicines in people who are substance abusers were excluded. The random effect meta-analysis model was used to pool the prevalence among the population-based studies.

Results

Of 2355 peer-reviewed studies initially identified, 53 were included in this review. According to the study design, the prevalence varied, but the overall pooled prevalence in the population-based studies was: 16.2% for misuse, 2.0% for abuse, and 7.2% for dependence. The common OTC medicines groups involved in the problematic use were analgesics (with or without codeine), sedative antihistamines, cough mixtures containing dextromethorphan. Physical, psychological, social and financial harms were associated with problematic use of OTC medicines in addition to hospitalisation and death. Interventions for the affected individuals were provided mainly through the community pharmacies, general practices and specialised addiction centres.

Conclusion

The problematic use of OTC medicines is quite prevalent in adults, necessitating raising public awareness about their safe use. In addition, innovative harm minimisation models need to be developed, evaluated and implemented across health care settings.

Misuse of medication in adult substance misuse services: a systematic review protocol

INTRODUCTION

There is a growing concern about the misuse of over the counter (OTC) and prescription only medication (POM) because of the impact on physical and mental health, drug interactions, overdoses and drug-related deaths. These medicines include opioid analgesics, anxiolytics such as pregabalin and diazepam and antidepressants. This protocol outlines how a systematic review will be undertaken (during June 2021), which aims to examine the literature on the pattern of OTC and POM misuse among adults who are accessing substance misuse treatment services. It will include the types of medication being taken, prevalence and demographic characteristics of people who access treatment services.

METHODS AND ANALYSIS

An electronic search will be conducted on the Cochrane, OVID Medline, Pubmed, Scopus and Web of Science databases as well as grey literature. Two independent reviewers will conduct the initial title and abstract screenings, using predetermined criteria for inclusion and exclusion. If selected for inclusion, full-text data extraction will be conducted using a pilot-tested data extraction form. A third reviewer will resolve disagreements if consensus cannot be reached. Quality and risk of bias assessment will be conducted for all included studies. A qualitative synthesis and summary of the data will be provided. If possible, a meta-analysis with heterogeneity calculation will be conducted; otherwise, Synthesis Without Meta-analysis will be undertaken for quantitative data. The reporting of this protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.

ETHICS AND DISSEMINATION

Ethical approval is not required. Findings will be peer reviewed, published and shared verbally, electronically and in print, with interested clinicians and policymakers.

An Evaluation of Opioid Use in Black Communities: A Rapid Review of the Literature

BACKGROUND

There are multiple aspects of the opioid crisis among Black people, who have been left out of the broader conversation. Despite evidence of increased opioid overdose deaths, less is known about opioid use among Black people. This review synthesizes research on Black people who use opioids; the goals are to advance knowledge, highlight research gaps, and inform clinical practice.

METHODS

This rapid review investigating opioid use among Black people utilized systematic review methods and was conducted according to a predefined protocol with clear inclusion criteria (PROSPERO ID: 177071). A comprehensive search strategy was used, including published and gray-literature sources (i.e., literature that has not been formally published). A narrative summary of the results is presented.

RESULTS

A total of 76 works were selected for inclusion and full text review. Sex, age, geographic location, and involvement in the carceral system were associated with the use of opioids among Black individuals. Non-epidemiologic factors included treatment-seeking patterns, disparate clinician prescribing, and social determinants.

CONCLUSIONS

Through this rapid review we suggest three main areas of focus: (1) including culturally informed collection methods in epidemiologic surveys to accurately reflect prevalences, (2) funding research that specifically addresses the importance of culture in accessing treatment, and (3) directly studying how social determinants can improve or exacerbate health outcomes. Focusing on the unique needs of Black people who use opioids is warranted to increase treatment initiation and adherence among a population less likely to engage with the traditional health care system.

Prevalence and correlates of prescription drug diversion and misuse among people living with HIV in the eThekwini district, KwaZulu-Natal, South Africa

BACKGROUND

Prescription drug diversion, and misuse has increased over the past decade and is notably in high-income-countries and significantly contributes to the opioid epidemic. People living with HIV (PLWH) are particularly vulnerable to prescription drug diversion, and misuse as most experience chronic pain, mental health problems and HIV-related illnesses. The researchers investigated the prevalence and correlates of prescription drug diversion, and misuse among PLWH in the eThekwini district, KwaZulu-Natal.

METHODS

A cross-sectional study was conducted among 392 PLWH, conveniently recruited from the public healthcare facilities located in rural, semi-urban and urban areas of the eThekwini district. Participants answered questions about their background, prescription medications, substance use, and prescription drug diversion, and misuse. Descriptive analysis was performed to estimate the prevalence of prescription drug diversion, and misuse. Multivariable logistic regression was used to identify predictors of prescription drug diversion, and misuse.

FINDINGS

Overall, 13% of the participants reported lifetime prescription drug diversion. The most common type of diversion was using prescription medication not prescribed by a healthcare provider (11%), followed by sharing of prescription medication (9%) and buying prescription medication without a medical script (5%). Twenty-three per cent of the participants reported prescription drug misuse in the past 90 days, with using prescription medication without a healthcare providers' guidance (9%) and not following the scheduled time periods (8%) being the most common reported types of misuse. Self-medicating was identified as a risk factor for prescription drug misuse. There was no association between ART adherence and prescription drug diversion, and misuse.

CONCLUSION

The study findings contribute to improving the limited data available on prescription drug diversion, and misuse among PLWH in South Africa. The prevalence underscores a need for urgent interventions when prescribing medications with potential risks. Addressing the risk of self-medicating is imperative for HIV care outcomes and to avert death.

Pharmacological Aspects of Over-the-Counter Opioid Drugs Misuse

Several over-the-counter (OTC) drugs are known to be misused. Among them are opioids such as codeine, dihydrocodeine, and loperamide. This work elucidates their pharmacology, interactions, safety profiles, and how pharmacology is being manipulated to misuse these common medications, with the aim to expand on the subject outlined by the authors focusing on abuse prevention and prevalence rates. The reviewed literature was identified in several online databases through searches conducted with phrases created by combining the international non-proprietary names of the drugs with terms related to drug misuse. The results show that OTC opioids are misused as an alternative for illicit narcotics, or prescription-only opioids. The potency of codeine and loperamide is strongly dependent on the individual enzymatic activity of CYP2D6 and CYP3A4, as well as P-glycoprotein function. Codeine can also be utilized as a substrate for clandestine syntheses of more potent drugs of abuse, namely desomorphine (“Krokodil”), and morphine. The dangerous methods used to prepare these substances can result in poisoning from toxic chemicals and impurities originating from the synthesis procedure. OTC opioids are generally safe when consumed in accordance with medical guidelines. However, the intake of supratherapeutic amounts of these substances may reveal surprising traits of common medications.

Experiences of over-the-counter codeine misusers and accounts of recovery: A qualitative study in Tasmania, Australia

INTRODUCTION AND AIMS

There is international concern about misuse of over-the-counter (OTC) codeine, yet few studies have reported the perspectives of misusers themselves. This study explored the experience of OTC codeine misuse and recovery in Tasmania, Australia.

DESIGN AND METHODS

Semi-structured telephone interviews were conducted with 15 self-identified long-term users of OTC codeine. The interview guide prompted responses about reasons for codeine use, positive and negative impacts, recovery, identity and codeine accessibility. Transcripts were analysed abductively using qualitative content analysis. Categories that emerged from misuser accounts were aligned to three broad temporal phases: (i) transition to misuse; (ii) growing awareness; and (iii) towards recovery.

RESULTS

Salient features of the misuse experience included: initial use for the self-treatment of physical pain; ongoing use to self-medicate physical pain, stress or mental health conditions; a perception of safety of OTC codeine; an insidious transition from use to misuse; growing awareness of a problem over time; support provided by family, friends and the internet; recovery through self-change; and recognition that recovery is an ongoing process.

DISCUSSION AND CONCLUSIONS

Knowledge and understanding of the experience of OTC codeine misuse and recovery is critical to inform and tailor approaches to prevention and intervention. The findings suggest that strategies to improve the management of pain, stress and mental health, raise self-awareness of problematic use and potential for self-change, and increase social and web-based supports, should be considered when designing health policy initiatives that aim to reduce misuse.

'For pain, no shame' and 'My secret solace': Accounts of over-the-counter codeine dependence using Q methodology

BACKGROUND

Dependence on over-the-counter (OTC) codeine is recognised internationally as a rising public health issue. The effectiveness of health intervention strategies may be influenced by the beliefs held by those who are dependent. Applying Q methodology, this study aimed to identify shared accounts of OTC codeine dependence.

METHODS

Twenty-six participants from Tasmania, Australia, met eligibility criteria for the study as long-term OTC codeine users with a Severity of Dependence Score of five or higher. Forty-six opinion statements about OTC codeine dependence were sourced from the literature and online discussion forums. These were rank-ordered by participants from least to most agree and explanatory comments for the most strongly positioned statements were provided. By-person factor analysis was used to group participants who had sorted the statements similarly.

RESULTS

Two distinct accounts of OTC codeine dependence were identified. Participants representing Factor One, 'For pain, no shame', were not ashamed of their OTC codeine use, believed access should not be restricted and regarded it as necessary for the relief of physical pain. In contrast, Factor Two, 'My secret solace', was characterized by feelings of guilt and shame. Participants in this group intentionally used codeine for its effects on mood; to help them relax and to relieve stress, rather than solely for pain relief. They did not consider regular use of codeine to be socially acceptable and hid their use from others.

CONCLUSION

The way in which OTC codeine use is viewed by those who are dependent is not uniform. Two distinct accounts were identified in this sample. Participants from each group varied in their beliefs about access, causality, reasons for use and feelings of legitimacy and shame. An understanding of these differences can be used to better target interventions and guide policy for the prevention and management of OTC codeine dependence.

Prescription drug diversion among people living with HIV: a systematic scoping review

OBJECTIVES

Globally, people living with HIV (PLWH) are at greater risk for various infections and chronic pain, therefore, vulnerable to prescription drug diversion which might negatively impact HIV care. The study purpose is to gather evidence on prescription drug diversion among PLWH.

STUDY DESIGN

This is a systematic scoping review.

METHODS

Arksey and O'Malley's framework and recommendation by Levac et al. were used to guide this study. Literature was searched in PubMed, Google Scholar, EBSCOhost (Academic Search Complete, MEDLINE and Newspaper Source) and Open Access Theses and Dissertations. Studies reporting evidence of prescription drug diversion from January 1996 to July 2017 were included. Thematic content analysis was performed to summarize data on the prevalence.

RESULTS

Twenty-nine studies were eligible for data synthesis. Twenty-six studies were conducted in the United States of America (USA), one study in France and two multicountry studies; one study in Kenya and Uganda and the other study in Botswana, Kenya, Malawi, South Africa; Zimbabwe, India, Thailand, Brazil and the USA. Research evidence shows high prevalence of prescription drug diversion for analgesics and antiretroviral drugs; meanwhile, stimulants and erectile dysfunction drugs were the least diverted drugs among PLWH. There is a research gap in low- to middle-income countries (LMICs) investigating prescription drug diversion among PLWH.

CONCLUSION

Our findings reveal that diversion of various prescription drug classes among PWLH exists. There is lack of research in LMICs. We recommend research in LMICs where there is high HIV prevalence.

The Opioid Epidemic in Africa And Its Impact

Purpose of review

Opioid use disorder (OUD) is a global phenomenon and is on the rise in Africa, denoting a shift from historical patterns of drug transport to internal consumption. In contrast, opioids for clinical pain management in Africa remain among the least available globally. This region also has the highest HIV and HCV disease burden, and the greatest shortages of health workers and addiction treatment. We undertook a systematic review of the literature to describe opioid use in Africa and how it is being addressed.

Recent findings

A total of 84 articles from 2000 to 2018 were identified. Descriptions of country-specific populations and patterns of opioid misuse were common. A smaller number of articles described interventions to address OUD.

Summary

OUD occurs in sub-Saharan Africa, with attendant clinical and social costs. Evidence-based policies and health system resources are needed to promote OUD prevention and management, and infectious disease transmission reduction.

A comparative analysis of pharmacists' perspectives on codeine use and misuse - a three country survey

BACKGROUND

The misuse of codeine is of increasing concern in a number of countries, particularly as this relates to over -the-counter pain and cough relief medication, and is also supplied as a prescription medicine. The study aimed to obtain and analyse the opinions and experience of pharmacy staff with regard to codeine misuse.

METHODS

A cross-sectional web-based survey of pharmacy staff's perspectives on this issue was administered through professional or regulatory bodies and completed by samples drawn in South Africa (n = 124), Ireland (n = 464) and the United Kingdom (n = 129).

RESULTS

The majority of participants reported combination codeine-containing products as most popular, but significantly more pharmacy staff in South Africa reported codeine-containing cough syrups as most commonly popular (X² = 122.7(2), p < 0.001). Codeine use was also seen significantly more of a public health problem in South Africa than in the other two countries (X² = 7.6(2), p = 0.02). There was no difference across countries in the level of codeine misuse reported by pharmacy staff. Further findings indicate that professional training and education is desired, with unequivocal findings for the need for greater codeine control (X² = 12.0(2), p = 0.002).

CONCLUSION

In conclusion, there were some inter-country differences, but overall the findings seem to suggest that pharmacists across all three countries view codeine misuse as a problem among their customers. Recommendations centre on risk management, surveillance and staff training.
