Mental health services in Gauteng, South Africa: A proxy evaluation using pharmaceutical data

Background: South African legislation advocates for equitable access to mental healthcare services integrated into general healthcare settings. Mental, neurological, and substance use (MNS) disorders are often comorbid. Pharmacoepidemiology provides indirect evidence of service provision for conditions amenable to medicine treatment. Aim: The study aims to evaluate medicine procurement for MNS disorders at different service levels in the health system. Setting: The Public health sector, Gauteng province formed the setting for the study. Method: A secondary analysis of the Gauteng pharmaceutical database was conducted using Anatomic Therapeutic Chemical (ATC) and defined daily dose (DDD) methodology. Anatomic Therapeutic Chemical classes of medicines for MNS disorders were included. Defined daily doses and costs were calculated per 1000 population served by each facility and service level. Statistical comparisons were made using chi-square testing. Results: General healthcare settings accounted for 90% (R118 638 248) and specialised hospitals for 10% (R13 685 032) of expenditure on medicines for MNS disorders, procuring 94% (n = 49 442 474) and 6% (n = 3 311 528) of DDDs, respectively. Although district clinics procured 60% of DDDs, they procured the least per 1000 population served, whereas district hospitals procured the most. For almost all ATC classes, procurement differed significantly between municipalities at every service level and between specialised hospitals. Conclusion: In Gauteng province, most medicines for MNS disorders are procured by general healthcare services, but access to care may not be equitable. While population coverage at district clinics appears low, district hospitals may experience the greatest care burden. Research regarding quality of care at each service level is recommended. Contribution: This study provides insight into service provision for MNS disorders.

Strengthening healthcare through family medicine training in the Gambia: The journey so far

According to the World Health Organizations (WHO) family medicine forms the bedrock upon for accessible, affordable and equitable healthcare for any country. The need for family doctors is more acute for low income countries like The Gambia. More so that The Gambian health infrastructure is suboptimal and appropriate health personnel is low. This is worsened by brain drain leading to poor health indices. Despite these challenges and more, the department of Family Medicine was accredited for training in the Gambia with improved infrastructure (at the training centre), with 7 residents. Though there are still challenges there are also opportunities and strengths. There is therefore hope that the right personnel will be produced for an improved Gambian health system.

In vivo studies could not confirm in vitro prophylactic synergism between Moringa essential oil and Lactobacillus reuteri (MT180537)

Abstract Aerobic vaginitis (AV) is a recently defined vaginal recurring infection, which is treated with antibiotics. However, excessive and prolonged use of antibiotics disrupts healthy vaginal microflora and leads to the emergence of antibiotic resistance among pathogens. This situation has directed researchers to explore alternative antimicrobials. The current study describes in vitro and in vivo antimicrobial efficacy and pharmaceutical interactions between plant essential oils (EOs) and five lactic acid bacteria (LABs), isolated from the healthy vagina, against E. faecalis, one of the major etiological agents of AV. In vitro experiments confirm good antimicrobial activity of both plant EOs and cell free supernatant (CFS) from LABs. Based on high antimicrobial efficacy, Moringa essential oil (MO) was selected to determine its nature of interaction with CFS of five LAB strains. Synergism was recorded between MO and CFS of L. reuteri (MT180537). To validate in vitro findings, prophylactic responses of individual and synergistic application of MO and L. reuteri (MT180537) were evaluated in an E. faecalis (MW051601) induced AV murine model. The prophylactic efficacy was evidenced by a reduction in intensity of clinical symptoms, E. faecalis (MW051601) count per vaginal tissue along with a reduction in AV associated changes in histological markers of infection in animals receiving Moringa essential oil and L. reuteri (MT180537) alone or in combination. However, significant synergism between Moringa essential oil and L. reuteri (MT180537) could not be observed. Our data confirms the importance of in vivo experiments in deducing pharmacological interactions.

Resumo Vaginite aeróbica (VA) é uma infecção vaginal recorrente definida recentemente, que é tratada com antibióticos. No entanto, o uso excessivo e prolongado de antibióticos perturba a microflora vaginal saudável e leva ao surgimento de resistência aos antibióticos entre os patógenos. Esta situação levou os pesquisadores a explorar antimicrobianos alternativos. O presente estudo descreve a eficácia antimicrobiana in vitro e in vivo e as interações farmacêuticas entre óleos essenciais vegetais (OE) e cinco bactérias lácticas (BAL), isoladas de vagina sã, contra E. faecalis, um dos principais agentes etiológicos da AV. Os experimentos in vitro confirmam a boa atividade antimicrobiana de ambos os EOs de plantas e sobrenadante livre de células (CFS) de LABs. Com base na alta eficácia antimicrobiana, o óleo essencial de Moringa (MO) foi selecionado para determinar sua natureza de interação com o sobrenadante livre de células (CFS) de cinco cepas de LAB. Sinergismo foi registrado entre MO e CFS de L. reuteri (MT180537). Para validar os resultados in vitro, as respostas profiláticas da aplicação individual e sinérgica de MO e L. reuteri (MT180537) foram avaliadas em um modelo murino AV induzido por E. faecalis (MW051601). A eficácia profilática foi evidenciada por uma redução na intensidade dos sintomas clínicos, contagem de E. faecalis (MW051601) por tecido vaginal, juntamente com uma redução nas alterações associadas a AV nos marcadores histológicos de infecção em animais que receberam óleo essencial de Moringa e L. reuteri (MT180537) sozinho ou em combinação. No entanto, não foi possível observar sinergismo significativo entre o óleo essencial de Moringa e L. reuteri (MT180537). Nossos dados confirmam a importância dos experimentos in vivo na dedução de interações farmacológicas.

Preparation and in vivo Distribution of Essential Oil from Alpinia zerumbet Fructus Encapsulated Nanoemulsions / 中国实验方剂学杂志

ObjectiveTo prepare oral nanoemulsions encapsulating essential oil from Alpinia zerumbet fructus（EOFAZ） and to investigate its pro-absorption effect in vitro and distribution in vivo. MethodThe proteoglycan conjugate polysaccharides of vinegar-processed Bupleuri Radix-bovine serum albumin（VBCP-BSA） was prepared by Maillard reaction of VBCP and BSA. Taking VBCP-BSA as emulsifier， vitamin B12（VB12） as absorption enhancer， and medium chain triglycerides mixed with EOFAZ as oil phase， the nanoemulsions loaded with EOFAZ was prepared by high energy emulsification method. The particle size， particle size distribution， surface Zeta potential， EOFAZ content and appearance and morphology of the nanoemulsions were characterized， and fluorescein tracer method was used to investigate the absorption effect of fluorescein-labeled EOFAZ nanoemulsions in vitro and their distribution in vivo. ResultVBCP-BSA was formed by Maillard reaction for 48 h with high grafting rate. Using VBCP-BSA as emulsifier， the homogeneous pink nanoemulsions was prepared and denoted as EOFAZ@VBCP-BSA/VB12. The particle size of the nanoemulsions was less than 100 nm and the particle size distribution was uniform. The surface of the nanoemulsions was a weak negative charge， and the shape was spherical. The encapsulation rate of the nanoemulsions for EOFAZ was greater than 80%， which had a good absorption effect in vitro and could enhance liver accumulation after oral administration. ConclusionThe designed proteoglycan nanoemulsions can effectively load EOFAZ， promote oral absorption and enhance liver distribution， which can provide experimental basis for the development of oral EOFAZ liver protection preparations.

O fim da extensão das patentes e as Parcerias para Desenvolvimento Produtivo: reflexos no acesso a medicamentos no Brasil / The end of patent extensions and the Productive Development Partnerships: effects on access to medicines in Brazil

Resumo A covid-19 jogou luz sobre o impacto negativo da propriedade intelectual na saúde e deu nova relevância à Ação Direta de Inconstitucionalidade 5529/DF, que, acatada pelo Supremo Tribunal Federal em 2021, culminou na extinção da extensão automática de patentes no Brasil. Este estudo busca analisar o efeito do julgamento histórico da ADI 5529/DF sobre pedidos de patente e as patentes de interesse das Parcerias para Desenvolvimento Produtivo (PDP). Trata-se de um estudo com base em uma pesquisa documental de análise do andamento, até 31 de dezembro de 2020, de 90 pedidos de patente relacionados a 15 medicamentos objetos de PDP. Nos sites do Instituto Nacional de Propriedade Industrial, do Ministério da Saúde, da Anvisa e da Câmara de Regulação do Mercado de Medicamentos, foram pesquisadas variáveis para comparar o cenário patentário dos medicamentos com o das PDP. De 88 pedidos válidos, 28 patentes foram concedidas, das quais dezessete foram estendidas para mais de vinte anos (média de 24 anos e nove meses). A decisão do STF resultou em mais de 68 anos de monopólio perdidos, potencialmente desanuviando alternativas para a produção de genéricos no país. Neste momento de retomada das PDP, estratégias para a superação de barreiras patentárias deveriam ser incorporadas à política.

Abstract The COVID-19 pandemic has shed light on the negative impact of intellectual property on health and has given new relevance to the Direct Action of Unconstitutionality 5529/DF, which was ruled by the Supreme Court in 2021, resulting in the extinction of automatic patent extensions in Brazil. This documentary case study analyzes the effects of the judicial decision on patent applications and patents of interest for Productive Development Partnerships (PDP), investigating the progress of 90 patent applications related to 15 PDPs drugs of interest until Decembre 31, 2020. Variables for comparing the drug patent scenario with that of the PDPs were researched on the websites of the National Institute of Industrial Property, the Ministry of Health, ANVISA, and the Brazilian Medicines Market Regulation Chamber. Of 88 valid applications, 28 patents were granted, 17 of which had been extended to more than 20 years (24 years and 09 months average). The court decision resulted in a loss of over 68 years of monopoly, potentially opening alternatives for generic production. This resumption of the PDP policy should incorporate strategies to overcome patent barriers.

Retrospective review of medicine utilization for noncommunicable diseases in three public sector pharmacies in Jamaica / Revisión retrospectiva del uso de medicamentos para enfermedades no transmisibles en tres farmacias del sector público de Jamaica / Revisão retrospectiva do uso de medicamentos para doenças não transmissíveis em três farmácias da rede pública na Jamaica

ABSTRACT Objective. The rational use of medicines offers a cost-saving strategy to maximize therapeutic outcomes for developing and developed countries. The aim of this study was to evaluate the rational use of medicines for selected noncommunicable diseases (NCDs) at three pharmacies at public hospitals in Jamaica using the World Health Organization's (WHO's) prescribing indicators. Methods. In this retrospective cross-sectional study, prescriptions for adult outpatients containing at least one medicine for cardiovascular disease, diabetes, cancer, chronic obstructive pulmonary disease or asthma that were filled between January and July 2019 were reviewed using WHO's prescribing indicators for the rational use of medicines. Data were analyzed and expressed as descriptive and inferential statistics. For all analyses conducted, significance was determined at P < 0.05. Results. A total of 1 500 prescriptions covering 5 979 medicines were reviewed; prescriptions were mostly written for female patients aged 42-60 years. Polypharmacy was observed in 35.6% (534) of prescriptions, and there was an average of 4 medicines per prescription, with a maximum of 17. Most of the prescriptions at each site were filled, with the main reason for not dispensing a medicine being that it was out of stock. Generic prescribing was high for all sites, accounting for more than 95% (5 722) of prescribed medicines. There was full compliance with prescribing according to the WHO Model List of Essential Medicines at two of the sites, but it was just off the target at Site 1, by 1.4%. Conclusions. The WHO guidelines for the rational use of medicines were followed with respect to the proportion of medicines prescribed from the WHO Model List and the proportion of antibiotics prescribed. The number of medicines per prescription and the proportion of medicines prescribed by generic name did not meet the WHO criteria. However, prescribing was aligned with treatment guidelines for the selected NCDs.

RESUMEN Objetivo. El uso racional de los medicamentos proporciona una estrategia de ahorro de costos para maximizar los resultados terapéuticos tanto en los países en desarrollo como en los países desarrollados. El objetivo de este estudio fue evaluar el uso racional de medicamentos para algunas enfermedades no transmisibles (ENT) seleccionadas en tres farmacias de hospitales públicos de Jamaica, usando los indicadores de prescripción de la Organización Mundial de la Salud (OMS). Métodos. En este estudio transversal retrospectivo se examinaron las prescripciones realizadas a pacientes ambulatorios adultos que incluían al menos un medicamento para enfermedades cardiovasculares, diabetes, cáncer, enfermedad pulmonar obstructiva crónica o asma, dispensadas entre enero y julio del 2019, utilizando los indicadores de prescripción para el uso racional de medicamentos de la OMS. Los datos se analizaron y expresaron mediante estadística descriptiva e inferencial. Para todos los análisis realizados se estableció un nivel de significación de p <0,05. Resultados. Se examinó un total de 1 500 prescripciones que incluían 5 979 medicamentos; la mayor parte de ellas correspondían a pacientes de sexo femenino de 42 a 60 años. Se observó que había polimedicación en el 35,6% (534) de las prescripciones, con un promedio de 4 y un máximo de 17 medicamentos por receta. En todos los centros se dispensó la mayor parte de los medicamentos prescritos, y el motivo principal para no hacerlo fue la falta de existencias del medicamento en cuestión. La prescripción de genéricos fue elevada en todos los centros y supuso más del 95% (5 722) de los medicamentos prescritos. En dos centros la prescripción se realizó en su totalidad de acuerdo con la Lista Modelo de Medicamentos Esenciales de la OMS, pero en el centro 1 no se alcanzó el objetivo por un 1,4%. Conclusiones. Se siguieron las directrices de la OMS para el uso racional de medicamentos en cuanto a la proporción de medicamentos prescritos de la Lista Modelo de la OMS y la proporción de antibióticos prescritos. El número de medicamentos por receta y la proporción de medicamentos prescritos mediante su nombre genérico no cumplieron con los criterios de la OMS. Sin embargo, las prescripciones estaban en consonancia con las directrices de tratamiento de las enfermedades no transmisibles seleccionadas.

RESUMO Objetivo. O uso racional de medicamentos é uma estratégia de contenção de custos para maximizar os resultados terapêuticos em países desenvolvidos e em desenvolvimento. O objetivo deste estudo foi avaliar o uso racional de medicamentos para algumas doenças não transmissíveis selecionadas em três farmácias de hospitais públicos na Jamaica a partir dos indicadores de prescrição preconizados pela Organização Mundial da Saúde (OMS). Métodos. Estudo transversal retrospectivo que avaliou receitas médicas de pacientes ambulatoriais adultos contendo pelo menos um medicamento prescrito para doença cardiovascular, diabetes, câncer, doença pulmonar obstrutiva crônica ou asma e dispensadas entre janeiro e julho de 2019. A avaliação foi realizada a partir dos indicadores de prescrição preconizados pela OMS para o uso racional de medicamentos. Os dados obtidos foram analisados por meio de estatísticas descritivas e inferenciais. O nível de significância de p <0,05 foi adotado em todas as análises. Resultados. Ao todo, foram analisadas 1 500 receitas médicas compreendendo 5 979 medicamentos. Em sua maioria, as receitas foram prescritas para pacientes do sexo feminino com idades entre 42 e 60 anos. A polifarmácia foi observada em 35,6% (534) das receitas; em média, foram prescritos 4 medicamentos, até um máximo de 17. As farmácias estudadas dispensaram a maior parte dos medicamentos receitados. O principal motivo para não fornecer algum medicamento foi o desabastecimento. O percentual de medicamentos genéricos foi alto em todos os locais, representando mais de 95% (5 722) do volume receitado. Houve plena observância da Lista Modelo de Medicamentos Essenciais da OMS nas receitas analisadas em dois dos locais estudos, e observância quase completa (diferença de 1,4%) no local 1. Conclusões. As diretrizes da OMS de uso racional de medicamentos foram cumpridas no que se refere ao percentual de medicamentos receitados de acordo com a Lista Modelo da OMS e o percentual de antibióticos receitados. Os critérios da OMS não foram cumpridos quanto ao número de medicamentos por receita e ao percentual receitado usando o nome genérico. Porém, os medicamentos foram receitados de acordo com as diretrizes terapêuticas para as doenças não transmissíveis selecionadas.

Política industrial farmacéutica, un requisito clave para la autonomía sanitaria de Colombia

Colombia depende de la importación de medicamentos, así como de gran parte de los materiales (principios activos y excipientes) requeridos para su elaboración; problemática que genera consecuencias sanitarias y macroeconómicas, las cuales se agudizan en el contexto de desindustrialización nacional y de disrupción tecnológica. De esta manera, se acepta que la disponibilidad y acceso a medicamentos y otras tecnologías sanitarias esenciales son un requisito fundamental para alcanzar la autonomía sanitaria de un país. Por lo tanto, resulta imprescindible coordinar esfuerzos entre diversos sectores sociales para desarrollar una agenda pública enfocada a la creación de condiciones que fortalezcan las capacidades científicas y tecnológicas de la industria farmacéutica local, y con ello, mejorar el suministro farmacéutico del país. En el presente documento se presentan conceptos teóricos y prácticos que deberían ser considerados en la definición y materialización de una política pública encaminada a fortalecer la industria farmacéutica y favorecer la autonomía sanitaria de Colombia.

Colombia has a notorious dependency on the importation of medicines, as well as a large part of the materials (active ingredients and excipients) required for their manufacture. This problem generates health and macroeconomic consequences, which are exacerbated in the context of national deindustrialization and technological disruption. In this way, it is accepted that the availability and access to medicines and other essential health technologies are a fundamental requirement to achieve the health autonomy of a country. Therefore, it is crucial to coordinate efforts between several social sectors to develop a public agenda focused on creating conditions that allow strengthening the scientific and technological capabilities of the local pharmaceutical industry, thereby, improving the country's pharmaceutical supply. This document presents conceptual and practical topics that should be considered to defining and materializing a public policy aimed at strengthening the local pharmaceutical industry and favoring Colombia's sanitary autonomy.

Comparison of 25-hydroxyvitamin D and bilirubin levels between patients with essential tremor and Parkinson's disease / Comparação dos níveis de 25-hidroxivitamina D e bilirrubina entre pacientes com tremor essencial e doença de Parkinson

Introduction: Differential diagnoses between essential tremor and Parkinson's disease is challenging in some individuals, with both disorders sharing similarities. Considering these links, we hypothesized that both conditions have a similar profile for some antioxidant molecules, including 25-hydroxyvitamin D and bilirubin. Methods: We performed a cross-sectional study comparing serum levels of 25-hydroxyvitamin D and bilirubin in 31 ET patients, 38 PD, and 65 controls matched for age. We used the Fahn-Tolosa-Marin scale for the severity of tremors in the ET group. We used Hohen-Yahr and MDS-UPDRS part III scales in the PD group. In addition, we evaluated sociodemographic characteristics, including age, sex, ethnicity, years of study, duration of disease, and use of primidone. Results: We found no differences in serum levels for 25-hydroxyvitamin D or bilirubin subtype levels between the ET and PD groups. We found low levels of indirect bilirubin in the PD group compared to the controls. We did not find differences between ET and controls in all biomarkers of the study. Conclusion: ET and PD patients have similar profiles for 25-hydroxyvitamin D and bilirubin serum levels. The discovery of differences in oxidative stress biomarkers in both conditions, mainly low-cost substances available clinically, can assist in the differential diagnosis and, in the future, prognostication and better therapy management (AU).

Introdução: O diagnóstico diferencial entre tremor essencial (TE) e a doença de Parkinson (DP) é desafiador em alguns indivíduos com ambas as afecções apresentando algumas similaridades. Assim sendo, hipotetizamos que ambas têm perfil similar de algumas moléculas antioxidantes, incluindo 25-hidroxivitamina D e bilirrubina. Méto-dos: Realizamos um estudo transversal comparando os níveis séricos de 25-hidroxivitamina D e bilirrubinas em 31 indivíduos com TE, 38 com DP e 65 controles pareados por idade. A escala de Fahn-Tolosa-Marin foi usada para avaliação da gravidade do tremor no grupo com TE e Hohen-Yahr e UPDRS parte III na avaliação do grupo com DP. Também foram avaliadas as características sociodemográficas. Resultados: Não encontramos diferenças nos níveis séricos de 25-hidroxivitamina D ou bilirrubina entre os grupos TE e DP. Encontramos baixos níveis de bilirrubina indireta no grupo DP comparado aos controles. Não encontramos diferenças entre os grupos com TE e controles em nenhum dos biomarcadores do estudo. Conclusão: Pacientes com TE e DP apresentam níveis séricos semelhantes de 25-Hidroxivitamina D e bilirrubinas. Diferenças nos biomarcadores de estresse oxidativo em ambas as condi-ções, principalmente substâncias de baixo custo disponíveis na clínica, pode auxiliar no diagnóstico diferencial e, futuramente, no prognóstico e otimização terapêutica (AU).

Essential oil of Cordia curassavica (Jacq) Roem. & Schult: in vitro and in silico evaluation of effects on dengue virus replication and cytokines production / Aceite esencial de Cordia curassavica (Jacq) Roem. & Schult: evaluación in vitro e in silico del efecto sobre la replicación del virus dengue y la producción de citoquinas

The lack of effective conventional therapie s against dengue has created an interest in herbal preparations as alternative therapies. In the present study, in vitro effects of Cordia curassavica essential oil (EO) on both dengue virus replication and cytokine production were examined. Predictions of molecular interactions between EO compounds and virus and cell proteins were performed with AutoDock Vina. The EO inhibited replication of dengue virus serotypes at IC 50 < 30 µg/mL, and it reduced 87% TNF - α, 67% IL - 8 and 46% IFN - α in LPS - stimulated PBMCs. The main EO compounds were trans - ß - caryophyllene (21.4%), germacrene D (17.8%), α - copaene (16.5%), trans - ß - guaiene (8.2%), and α - pinene (6.0%). The first two compounds, δ - cadinene, α - muurolene, α - cubebene and ß - burbonene were coupled to proteins involved in the TLR - 4 cytokine effector pathway. 3,7 - Guaiadiene was coupled to the viral E and C proteins. This study demonstrates the potential of C. curassavica EO as a starting point for discovering novel therapeutic for dengue.

La falta de terapias eficaces para el dengue ha suscitado interés por preparados herbales como terapias alternativas. En el presente estudio se examinaron efectos in vitro del aceite e sencial (AE) de Cordia curassavica sobre la replicación del virus dengue y producción de citoquinas. Se realizaron predicciones de interacciones moleculares entre los compuestos del AE y proteínas virales y celulares con AutoDock Vina. El AE inhibió la rep licación de serotipos del virus a CI 50 < 30 µg/mL y redujo 87% TNF - α, 67% IL - 8 y 46% IFN - α en MNCP. Los principales compuestos del AE fueron trans - ß - cariofileno, germacreno D, α - copaeno, trans - ß - guaieno y α - pineno. Los dos primeros compuestos, el δ - cadineno, el α - muuroleno, el α - cubebeno y el ß - burboneno se acoplaron a proteínas implicadas en la vía efectora de citoquinas TLR - 4. El 3,7 - guaiadiene se acopló a las proteínas virales E y C. Este estudio demuestra el potencial del AE de C. curassavica como punto de partida para descubrir nuevas tera pias para el dengue.

Factores asociados a la adherencia al tratamiento farmacológico en pacientes con diabetes sin hipertensión arterial

Objetivo: Identificar los factores asociados a la adherencia al tratamiento farmacológico en pacientes con diabetes mellitus tipo 2 sin hipertensión arterial. Materiales y métodos: Estudio transversal y analítico en pacientes con diabetes mellitus tipo 2 sin hipertensión arterial. Se integraron el grupo con adherencia al tratamiento (n = 145) y el grupo sin adherencia al tratamiento (n = 49), determinado por la escala de adherencia a la medicación de Morisky de 4 ítems (MMAS-4). Como factores asociados, se estudiaron sexo, vida en pareja, escolaridad, ocupación, edad agrupada en decenios y tiempo de evolución de la diabetes agrupada en menos de un año, de 1 a 5 años, de 6 a 10 años y más de 10 años. El plan de análisis estadístico incluyó la prueba de ji al cuadrado. Resultados: Se identificaron el sexo (p = 0,045), la vida en pareja (p = 0,045), la edad (p = 0,001) y el tiempo de evolución de la enfermedad (p = 0,001) como factores asociados a la adherencia al tratamiento farmacológico. La escolaridad no se identificó como un factor asociado a la adherencia terapéutica en el paciente con diabetes mellitus tipo 2 (p = 0,289). A mayor edad, menor adherencia al tratamiento farmacológico en el paciente con diabetes: el punto de corte se presenta a los 60 años; después de esta edad, el porcentaje en el grupo no adherente es mayor que en el grupo con adherencia (p = 0,001). A mayor tiempo de evolución de la diabetes, menor probabilidad de adherencia; en el grupo no adherente, el porcentaje de pacientes con más de 10 años de evolución es 67,3 % y en el grupo con adherencia el porcentaje corresponde a 33,8 % (p = 0,001). Conclusiones: Se identificaron los factores asociados a la adherencia al tratamiento farmacológico en pacientes con diabetes mellitus tipo 2 sin hipertensión arterial.

Objective: To identify the factors associated with adherence to drug therapy among patients with type 2 diabetes mellitus without hypertension. Materials and methods: A cross-sectional, analytical study conducted with patients with type 2 diabetes mellitus without hypertension, divided into an adherent group (n = 145) and a non-adherent group (n = 49), determined by the 4-item Morisky Medication Adherence Scale (MMAS-4). The associated factors were sex, cohabitation, schooling, occupation, age in 10-year groups and diabetes progression time grouped in less than 1 year, from 1 to 5 years, from 6 to 10 years and more than 10 years. The statistical analysis plan included the chi-square test. Results: The factors associated with adherence to drug therapy were identified as sex (p = 0.045), cohabitation (p = 0.045), age (p = 0.001) and disease progression time (p = 0.001). Schooling was not identified as a factor associated with adherence to drug therapy among patients with type 2 diabetes mellitus (p = 0.289). The older the patient with diabetes, the lower the adherence to drug therapy; the cut-off point was 60 years of age, after which the percentage in the non-adherent group was higher than in the adherent group (p = 0.001). The longer the diabetes progression time, the lower the probability of adherence; in the non-adherent group the percentage of patients with more than 10 years of disease progression was 67.3 % and in the adherent group the percentage was 33.8 % (p = 0.001). Conclusions: The factors associated with adherence to drug therapy among patients with type 2 diabetes mellitus without hypertension were identified
