Contribution of Ethnomedical Use Data to the Marketing Authorization of Traditional Herbal Medicines in Mali.

Background: To improve the supply of health care and health care products, traditional herbal medicines that are safe, effective, and of good quality need marketing authorizations. This study aims to determine the contribution of ethnomedical evidence to the marketing of traditional herbal medicines in Mali. Methods: This was a descriptive cross-sectional study conducted from December 2023 to March 2024 supplemented by a literature review of the legislative and regulatory provisions relating to traditional medicine and the requirements for marketing authorization of traditional herbal medicines in Mali and the West African sub-region. Results: The regulatory framework for marketing authorization is governed by decree no. 04-557/P-RM of 01 December 2004 and interministerial order no. 05-2203/MS-MEP-SG of 20 September 2005 in Mali. These texts set out the specific requirements for the marketing authorization of traditional plant-based medicines, depending on the category. They consider ethnomedical evidence drawn from long experience of traditional use as proof of efficacy and tolerance for category 2 traditional medicines. As a result, marketing authorizations were issued for 15 products derived from traditional medicine and pharmacopeia, 5 of which are included in the National List of Essential Medicines and the National Therapeutic Formulary of Mali. Conclusion: The use of ethnomedical evidence provides a good opportunity to obtain marketing authorization for phytomedicines derived from traditional medicine without having to go through long and costly non-clinical and clinical studies.

Pharmaceutical approaches for enhancing solubility and oral bioavailability of poorly soluble drugs.

High solubility in water and physiological fluids is an indispensable requirement for the pharmacological efficacy of an active pharmaceutical ingredient. Indeed, it is well established that pharmaceutical substances exhibiting limited solubility in water are inclined towards diminished and inconsistent absorption following oral administration, consequently resulting in variability in therapeutic outcomes. The current advancements in combinatorial chemistry and pharmaceutical design have facilitated the creation of drug candidates characterized by increased lipophilicity, elevated molecular size, and reduced aqueous solubility. Undoubtedly, the issue of poorly water-soluble medications has been progressively escalating over recent years. Indeed, 40% of the top 200 oral medications marketed in the United States, 33% of drugs listed in the US pharmacopoeia, 75% of compounds under development and 90% of new chemical entities are insufficiently water-soluble compounds. In order to address this obstacle, formulation scientists employ a variety of approaches, encompassing both physical and chemical methods such as prodrug synthesis, salt formation, solid dispersions formation, hydrotropic substances utilization, solubilizing agents incorporation, cosolvent addition, polymorphism exploration, cocrystal creation, cyclodextrins complexation, lipid formulations, particle size reduction and nanoformulation techniques. Despite the utilization of these diverse approaches, the primary reason for the failure in new drug development persists as the poor aqueous solubility of pharmaceutical compounds. This paper, therefore, delves into the foundational principles that underpin the implementation of various formulation strategies, along with a discussion on the respective advantages and drawbacks associated with each approach. Additionally, a discourse is provided regarding methodological frameworks for making informed decisions on selecting an appropriate formulation strategy to effectively tackle the key challenges posed during the development of a poorly water-soluble drug candidate.

Hirshfeld surface analysis reveals that 46.1% of the inter-molecular inter-actions are from H⋯H contacts, 28.6% are from H⋯O/O⋯H contacts and 14.7% are from H⋯C/C⋯H.

A review of the safety profile, antioxidant, anti-inflammatory, and bronchorelaxant activities of Waltheria indica Linn (Malvaceae): A potential antiasthmatic phytomedicine.

Introduction: Waltheria indica Linn (Malvaceae) is a widely distributed plant in West Africa. It is commonly used in Burkina Faso to treat inflammation-related diseases, including asthma. Previous reviews have focused on the ethnobotanical, traditional uses, phytochemistry, and pharmacological properties of Waltheria indica. This report aims to compile the biological and pharmacological activities that highlight the anti-asthmatic properties of Waltheria indica L. (W. indica). Method: Electronic databases, such as PubMed, Scopus, Hinari, SciFinder, Google Scholar, and ScienceDirect, were used to gather data on Watheria indica. Data on the toxicological, anti-inflammatory, antioxidant, and bronchorelaxant effects of W. indica were collected. Results: Twenty-three studies describing the biological and pharmacological activities relevant to assessing the anti-asthmatic properties of W. indica were found. Nine articles investigated the anti-inflammatory effects, and three manuscripts were found to have bronchorelaxant activity. Five publications reported the antioxidant activity of the plant extracts. Research on the extracts revealed a tolerable safety profile in rats and mice with an LD50 ranging from 300 to 5000 mg/kg body weight, depending on the parts of the plant used. Phenolic compounds, particularly flavonoids, alkaloids, and saponins, were found to be responsible for the activities involved in the assessment of anti-asthmatic properties. Conclusion: The results of this review suggest that W. indica could be a valuable resource for the treatment of asthma and other respiratory diseases. However, further chemical and pharmacological investigations are needed to understand its mechanism of action in treating asthma.

In the crystal of the title compound, C15H16O4, the mol-ecules are connected through C-H⋯O hydrogen bonds, generating [100] chains, which are crosslinked by weak π-π stacking inter-actions.

Systematic Review of Chemical Compounds with Immunomodulatory Action Isolated from African Medicinal Plants.

A robust, well-functioning immune system is the cornerstone of good health. Various factors may influence the immune system's effectiveness, potentially leading to immune system failure. This review aims to provide an overview of the structure and action of immunomodulators isolated from African medicinal plants. The research was conducted according to PRISMA guidelines. Full-text access research articles published in English up to December 2023, including plant characteristics, isolated phytochemicals, and immuno-modulatory activities, were screened. The chemical structures of the isolated compounds were generated using ChemDraw® (version 12.0.1076), and convergent and distinctive signaling pathways were highlighted. These phytochemicals with demonstrated immunostimulatory activity include alkaloids (berberine, piperine, magnoflorine), polysaccharides (pectin, glucan, acemannan, CALB-4, GMP90-1), glycosides (syringin, cordifolioside, tinocordiside, aucubin), phenolic compounds (ferulic acid, vanillic acid, eupalitin), flavonoids (curcumin, centaurein, kaempferin, luteolin, guajaverin, etc.), terpenoids (oleanolic acid, ursolic acid, betulinic acid, boswellic acids, corosolic acid, nimbidin, andrographolides). These discussed compounds exert their effects through various mechanisms, targeting the modulation of MAPKs, PI3K-Akt, and NF-kB. These mechanisms can support the traditional use of medicinal plants to treat immune-related diseases. The outcomes of this overview are to provoke structural action optimization, to orient research on particular natural chemicals for managing inflammatory, infectious diseases and cancers, or to boost vaccine immunogenicity.

Pulmonary function assessment among conventional and organic cotton farmers exposed to pesticides in the Central-West region of Burkina Faso.

BACKGROUND: Respiratory diseases have been associated with the exposure of populations to some environmental pollutants such as pesticides. To assess effects of pesticides on farmers' respiratory health, this study aimed to evaluate the pulmonary function of cotton farmers exposed to synthetic and natural pesticides in the Central-West region of Burkina Faso. METHODS: A cross-sectional study was conducted from June to July 2022 among 281 conventional and 189 organic cotton farmers. After collecting information on pesticide use conditions, pulmonary function tests (PFTs) were performed on each farmer according to the American Thoracic Society/European Respiratory Society guidelines, in order to assess chronic respiratory effects among cotton producers. Binary logistic regression was used to assess factors associated with the occurrence of ventilatory changes. RESULTS: Both conventional and organic cotton farmers reported similar chronic respiratory symptoms in different proportions. The main reported were rhinitis (54.45% conventional vs. 34.92% organic), chest pains (41.28% conventional vs. 23.81% organic), cough (33.45% conventional, 24.34% organic), breathlessness (31.67% conventional, 4.23% organic) (p<0.05). 16.18% and 27.50% of conventional male and female cotton farmers, respectively, had a restrictive defect. Among organic cotton farmers, 15.85% and 18.69%, respectively, of males and females had a restrictive defect. Furthermore, a significant increase in the predicted average percentage of FEV1/FVC ratio was observed among organic cotton farmers after salbutamol's use (p = 0.039). The type of cultivated cotton was not associated with ventilatory changes neither in the univariate analysis, nor in the multivariate analysis. Other factors such as farmers' age, BMI and insecticides use frequency per year were also important. Farmers who used insecticides more than 6 times per season had an increased risk of developing an obstructive defect (OR = 1.603; 95%CI: 0.484-5.309) compared to those who used them 6 times or less. CONCLUSION: Chronic respiratory signs and ventilatory impairments were found among conventional and, to our knowledge, for the first time among organic cotton producers. However, these health effects were more prevalent among conventional cotton farmers than organic ones.

Sex-dependent vulnerability for Wistar rats model following intranasal instillation with Klebsiella pneumoniae ATCC 43816 causing lobar pneumonia.

BACKGROUND: Klebsiella pneumoniae has become one of the major threats to public health as it causes nosocomial and community-acquired infections like lobar pneumonia. This infection causes acute inflammation in the lung, characterized by the recruitment of polymorphonuclear cells, generating free radicals, and decreasing the endogenous antioxidant balance system. Many experimental studies have focused on the induction, progression and resolution of infection up to its peak, but these documented processes remain highly random and their sex dependence un-elicited. These fluctuations of physiopathological parameters would impact disease progression depending on the animal's model and bacterial strain used. The present study investigated the sex-dependent vulnerability of Wistar rats to K. pneumoniae ATCC 43816 lobar pneumonia induced by the intranasal instillation method. METHODS: Experimental pneumonia was induced by K. pneumoniae ATCC 43816 in male and female Wistar rats following intranasal instillation. The physiopathogenesis of the disease was studied by bacteriological and histopathological exams, histomorphometric analysis of the blood and/or lung tissue, and body weight loss in infected animals. In addition, the overall severity of lesions was determined by the total score obtained by averaging the individual scores from the same group of animals. RESULTS: The K. pneumoniae ATCC 43816 strain showed inoculation dose-, incubation time of the disease- and sex-dependent- differences in its ability to induce lobar pneumonia. Evaluation of different parameters showed that the disease peaked on day 15 post-inoculation, with more pathogenic effects on female rats. This observed sex-dependence difference in Wistar rats was mainly highlighted by the determined lethal dose 50 (LD50), bacterial load count in whole blood and lung tissues, body weight loss, inflammatory granulomas forming and diffuse alveolar damages. The pathogenicity was confirmed by scoring the severity of pathologic lesions of lung tissues. CONCLUSIONS: The results obtained highlighted the gender-dependency in the physiopathogenesis processes of K. pneumoniae ATCC 43816 induced-lobar pneumonia, in Wistar rats. Female Wistar rats' susceptibility is useful in studying pathology and in preclinical trial investigations of new treatments for infectious pneumonia.

Development and optimization of a one step process for the production and sterilization of liposomes using supercritical CO2.

Liposomes are very interesting drug delivery systems for pharmaceutical and therapeutic purposes. However, liposome sterilization as well as their industrial manufacturing remain challenging. Supercritical carbon dioxide is an innovative technology that can potentially overcome these limitations. The aim of this study was to optimize a one-step process for producing and sterilizing liposomes using supercritical CO2. For this purpose, a design of experiment was conducted. The analysis of the experimental design showed that the temperature is the most influential parameter to achieve the sterility assurance level (SAL) required for liposomes (≤10-6). Optimal conditions (80 °C, 240 bar, 30 min) were identified to obtain the fixed critical quality attributes of liposomes. The conditions for preparing and sterilizing empty liposomes of various compositions, as well as liposomes containing the poorly water-soluble drug budesonide, were validated. The results indicate that the liposomes have appropriate physicochemical characteristics for drug delivery, with a size of 200 nm or less and a PdI of 0.35 or less. Additionally, all liposome formulations demonstrated the required SAL and sterility at concentrations of 5 and 45 mM, with high encapsulation efficiency.

Entomotherapy as an alternative treatment for diseases due to Gram-negative bacteria in Burkina Faso.

Insects are known for their harmful effects. However, they also benefit humans, animals, plants, and ecosystems. Its beneficial uses include entomophagy and entomotherapy. This study aimed to evaluate the antibacterial activity of insect extracts against Gram-negative bacteria. Antibacterial activities of thirteen crude extracts of medicinal insects were tested against twelve Gram-negative bacteria by diffusion on agar. Imipenem was used as an antibiotic for positive control. The thirteen extracts acted differently against certain Gram-negative bacteria. The largest inhibition diameter was for extracts of Cirina butyrospermi and Mylabris variabilis against Pseudomonas aeruginosa ATCC27853 and Salmonella enteritidis ATCC13076, respectively. The diameters of inhibition obtained using imipenem against these same bacterial strains were 13.0 ± 0.0 mm and 22 ± 1.0 mm, respectively. The lowest inhibition diameter (7.5 ± 0.0 mm) was obtained using Anopheles gambiae extract against Salmonella Typhimurium ATCC14028. Imipenem was active on all strains tested. The highest values of the index multi-resistance to insect's extracts were reported for Pseudomonas aeruginosa ATCC9027 and Serratia odorifera 652411. Overall, the results of this study confirmed the antibacterial activities of insects used by traditional health practitioners to treat different pathologies. Entomotherapy could be an alternative treatment for certain infectious pathologies caused by gram-negative bacteria.

Phytopharmaceutical practices of traditional health practitioners in Burkina Faso: a cross-sectional study.

BACKGROUND: Traditional health practitioners constitute an important part of the health care system in Burkina Faso, particularly in the supply of traditional herbal medicines. Quality and safety of these medicines rely heavily on practices employed during their traditional development. However, traditional phytopharmaceutical practices are poorly described in Burkina Faso. This study aimed to describe the phytopharmaceutical practices of traditional medicine practitioners in Burkina Faso. METHODS: This was a cross-sectional descriptive ethno-pharmaceutical study, conducted from October 1 to November 30, 2020, among traditional practitioners in four randomly selected health districts: Nongr-Massom (Centre region), Tenkodogo (Centre-East region), Diapaga (East region) and Dafra (Hauts-Bassins region). An anonymous semi-structured face-to-face questionnaire was used to collect socio-demographic data and data on raw materials and finished products. RESULTS: Sixty-seven (67) traditional health practitioners, aged 56 years on average, including a majority of men (72%), participated in the study. Gathering of wild medicinal plants was the main source of raw materials acquisition (51.5%), which were usually leaves (32.3%). These raw materials were usually sun-dried (43.9%) and packaged mostly in plastic bags (37.2%). They were derived from 60 plant species belonging to 33 botanical families. Fabaceae was the most represented family (18.7%) and Khaya senegalensis Juss. (Meliaceae) the most cited plant species (5.2%). The finished products had an average shelf life of 17 months and were usually prepared as a decoction (31.7%) and administered most often orally (71.4%). Gastrointestinal disorders were the main predictable adverse events of the finished products (54%). CONCLUSION: This study showed that THPs have important knowledge in the use of medicinal plants, but several shortcomings are observed in their phytopharmaceutical and plant protection practices. Continuous improvement of these practices, through education and training of traditional health practitioners, is essential for the conservation of plant biodiversity and quality assurance of traditional herbal medicines.

Use of traditional medicines among conventional medicine practitioners in Burkina Faso / Utilisation des médicaments traditionnels chez les praticiens de la médecine conventionnelle au Burkina Faso

INTRODUCTION: The integration of traditional medicine into biomedical health care practice is highly dependent on its acceptability by conventional medical practitioners. Its use by conventional practitioners was previously unknown in Burkina Faso. PURPOSE OF RESEARCH: The purpose of this study was to estimate the prevalence of traditional medicine use and the frequency of occurrence of adverse events associated with this use among conventional medical practitioners in Burkina Faso. RESULTS: The majority of the practitioners surveyed were women (56.1%) and the average age was 39.7±7 years. Nurses (56.1%), midwives (31.4%) and physicians (8.2%) were the most represented professions. The prevalence of the use of traditional medicines in the 12 months preceding the survey was 75.6%. Malaria was the main medical reason for using traditional medicines (28%). The frequency of reported adverse events was 10% and mainly concerned gastrointestinal disorders (78.3%). CONCLUSIONS: The majority of conventional medical practitioners in Burkina Faso use traditional medicines for their health problems. This finding suggests the effective integration of traditional medicine into biomedical health care practice which could benefit from good acceptability by these professionals.

Introduction: L'intégration de la médecine traditionnelle dans le système de santé moderne est fortement dépendante de son acceptabilité par les praticiens de ce système. Leur recours à la médecine traditionnelle était jusque-là méconnu au Burkina Faso. But de l'étude: Le but de cette étude était d'estimer la prévalence de l'utilisation des médicaments traditionnels et la fréquence de survenue des événements indésirables parmi les praticiens de santé conventionnels au Burkina Faso. Résultats: La majorité des praticiens enquêtés étaient des femmes (56,1 %) et l'âge moyen s'établissait à 39,7 ±7 ans. Les infirmiers (56,1 %), les sages-femmes (31,4 %) et les médecins (8,2 %) étaient les professions les plus représentées. La prévalence de l'utilisation de médicaments traditionnels durant les douze mois précédant l'enquête était de 75,6 %. Le paludisme apparaissait comme la principale raison médicale du recours aux médicaments traditionnels (28 %). La fréquence des événements indésirables rapportés s'élevait à 10 % et concernaient principalement des troubles gastro-intestinaux (78,3 %). Conclusions: Les praticiens de la médecine conventionnelle ont largement recours aux médicaments traditionnels. Cela suggère l'intégration effective de la médecine traditionnelle dans la pratique biomédicale des soins et la surveillance des risques associés à cette utilisation.

Current Status and Challenges of Pharmacovigilance of Traditional Medicines in French-Speaking West African (UEMOA) Countries.

BACKGROUND: West African Economic and Monetary Union (UEMOA) countries are characterised by a high prevalence of informal use of medicinal plants and traditional medicines by their population for health care, requiring the establishment of pharmacovigilance, in order to monitor the associated health risks. However, the state of implementation of pharmacovigilance for traditional medicines in UEMOA countries is not known. OBJECTIVE: This study aimed to assess the state of implementation of pharmacovigilance for traditional medicines in the eight UEMOA countries, describing the relevant community provisions, assessing the integration of traditional medicines monitoring into national pharmacovigilance systems and identifying related national challenges. METHODS: This was a cross-sectional study using questionnaires, conducted between 1 May and 31 August 2022. A face-to-face questionnaire was administered to officials responsible for the issue within UEMOA and the West African Health Organisation (WAHO). A second online questionnaire was specifically sent to the pharmacovigilance focal points of the eight UEMOA countries. Questionnaires were designed using the WHO indicators for pharmacovigilance. The face-to-face questionnaire collected two types of data, namely community policies and regulations on pharmacovigilance and technical and financial support from sub-regional organisations to countries. The online questionnaire sent to countries collected four categories of data on the study issue: structural data, process data, impact data and data on national challenges. RESULTS: As a community provision, WAHO has a harmonised regulatory framework for phytovigilance. The monitoring of traditional medicines is not effectively implemented in the pharmacovigilance systems of UEMOA countries. Only two reports of adverse events due to traditional medicines have so far been recorded in the Union. The countries have neither funding nor sufficient human resources for pharmacovigilance in general. Monitoring of traditional medicines in the unregulated market, training of stakeholders, risk communication, and integration of traditional health practitioners in reporting systems are the main challenges of countries for the development of pharmacovigilance for traditional medicines. CONCLUSION: The effective compliance of WAHO's harmonised phytovigilance regulatory framework by UEMOA countries and addressing the challenges identified by the countries constitute the basis for the development of pharmacovigilance for traditional medicines within UEMOA.

Preformulation study for the selection of a suitable polymer for the development of ellagic acid-based solid dispersion using hot-melt extrusion.

Ellagic acid is one of the most studied polyphenolic compounds due to its numerous promising therapeutic properties. However, this therapeutic potential remains difficult to exploit owing to its low solubility and low permeability, resulting in low oral bioavailability. In order to allow an effective therapeutic application of EA, it is therefore necessary to develop strategies that sufficiently enhance its solubility, dissolution rate and bioavailability. For this purpose, solid dispersions based on pre-selected polymers such as Eudragit® EPO, Soluplus® and Kollidon® VA 64, with 5% w/w ellagic acid loading were prepared by hot extrusion and characterized by X-ray diffraction, FTIR spectroscopy and in vitro dissolution tests in order to select the most suitable polymer for future investigations. The results showed that Eudragit® EPO was the most promising polymer for ellagic acid solid dispersions development because its extrudates allowed to obtain a solution supersaturated in ellagic acid that was stable for at least 90 min. Moreover, the resulting apparent solubility was 20 times higher than the actual solubility of ellagic acid. The extrudates also showed a high dissolution rate of ellagic acid (96.25% in 15 min), compared to the corresponding physical mixture (6.52% in 15 min) or the pure drug (1.56% in 15 min). Furthermore, increasing the loading rate of ellagic acid up to 12% in extrudates based on this polymer did not negatively influence its release profile through dissolution tests.

Use of supercritical CO2 for the sterilization of liposomes: Study of the influence of sterilization conditions on the chemical and physical stability of phospholipids and liposomes.

The effects of four potential supercritical carbon dioxide (ScCO2) sterilization conditions on the chemical stability of 9 phospholipids and on the physicochemical characteristics of liposomes consisting of stable phospholipids, as well as their sterilization efficiency were evaluated. These conditions were : C1 (ScCO2/70 °C/150 bar/240 min), C2 (ScCO2/0.25 % water/ 0.15% H2O2/ 0.5% acetic anhydride/38° C/85 bar/45 min), C3 (ScCO2/0.08 % peracetic acid/35° C/104 bar/180 min) and C4 (ScCO2/200 ppm H2O2/40 °C/270 bar/90 min). The results showed for phospholipids, a significant increase in hydrolysis products of 3.77 to 14.50 % and an increase in oxidation index of 6.10 to 430.50 % with unsaturated phospholipids for all tested conditions while with saturated phospholipids, no significant degradation was observed. Concerning the liposome formulation, no change in dispersion color and no phospholipid degradation were observed. However, a decrease in liposome size from 126.90 nm to 111.80 nm, 96.27 nm, 99.60 nm and 109.13 nm and an increase in the PdI from 0.208 to 0.271, 0.233, 0.285, and 0.298 were found with conditions C1, C2, C3 and C4 respectively. For the sterilization efficiency, conditions C1, C2 and C3 achieved the required sterility assurance level (SAL) of 10-6 for liposomes.

In Vitro Antioxidant and Anticancer Properties of Various E. senegalensis Extracts.

Although Erythrina senegalensis is a plant widely used in traditional medicine in sub-Saharan Africa, its biological properties have been poorly investigated to date. We first characterized by conventional reactions the composition of several stem bark extracts and evaluated in acellular and cellular assays their pro- or antioxidant properties supported by their high phenolic and flavonoid content, particularly with the methanolic extract. The pro- or antioxidant effects observed did not correlate with their IC50 concentrations against five cancer cell lines determined by MTT assay. Indeed, the CH2Cl2 extract and its ethyl acetate (EtOAc) subfraction appeared more potent although they harbored lower pro- or antioxidant effects. Nevertheless, at equipotent concentration, both extracts induced ER- and mitochondria-derived vacuoles observed by fluorescent microscopy that further led to non-apoptotic cell death. LC coupled to high resolution MS investigations have been performed to identify chemical compounds of the extracts. These investigations highlighted the presence of compounds formerly isolated from E. senegalensis including senegalensein that could be retrieved only in the EtOAc subfraction but also thirteen other compounds, such as 16:3-Glc-stigmasterol and hexadecanoic acid, whose anticancer properties have been previously reported. Nineteen other compounds remain to be identified. In conclusion, E. senegalensis appeared rich in compounds with antioxidant and anticancer properties, supporting its use in traditional practice and its status as a species of interest for further investigations in anticancer drug research.

Hospital preparations of ethanol-free furosemide oral solutions: Formulation and stability study.

Furosemide is a diuretic frequently used in the therapeutic management of edema associated with cardiac, renal, and hepatic failure and hypertension. However, there are a very low number of pharmaceutical dosage forms containing furosemide that are suitable for children under 6- years old. Therefore, there is a real need to develop hospital preparations, especially in the hospital. Four oral pediatric solutions of furosemide (2 mg/Ml) were formulated. Two of those solutions did not contain ethanol. For each formulation, 12 batches of 1600.0 Ml were prepared and packaged in 250.0 Ml brown glass bottles with polypropylene screw caps. The physicochemical properties (visual appearance, pH, osmolarity, drug content) and microbiological quality of the finished product were determined on the freshly prepared solutions and after 90 days of storage at 30°C/65% RH. The physicochemical and microbiological characteristics of the freshly prepared solutions were within the prescribed specifications. After 90 days of storage at 30°C/65% RH, the solutions containing sucrose and those without ethanol showed a slight decrease in pH and furosemide content of about 2.5%-4.5% (w/w). Despite this slight decrease, the characteristics remained within the prescribed specifications. Based on the stability profile of the ethanol-free solution containing sorbitol, it could be implemented in hospitals for the care of pediatric patients.

Design and Implementation of a Computerized Management System for Adverse Drug Reactions at the Sourô SANOU University Hospital (CHUSS) in Bobo-Dioulasso, Burkina Faso.

Pharmacovigilance is the science and activities related to the detection, evaluation, understanding and prevention of adverse drug reactions or any other possible drug-related problems. In our tropics, this discipline is in an embryonic state. The availability of a management system capable of responding to pharmacovigilance activities is the main objective of our study. The coding was done on the DJANGO Framework. Signal detection was done using the ROR method. We designed three modules which are the notification module, the analysis module and the statistics module. This study has allowed us to launch the basis for a computerization of the pharmacovigilance information system and partly meets our objective. However, it could lead to the integration of the dictionary of adverse effects such as MedDRA as well as the International Classification of Medicines (ATC, EphMRA).
