Willingness, Attitude, and Associated Factors towards Adverse Drug Reaction Reporting among Healthcare Providers in Mizan Tepi University Teaching Hospital, Southwest Ethiopia

Background. An adverse drug reaction (ADR) is harm that arises from the use of a drug. Adverse drug reactions have a huge impact on the health system since they result in drug-related morbidity and mortality as well as indirect costs such as loss of productivity at work. Reporting of adverse drug reactions to a relevant authority is one of the methods of enhancing medication safety; however, underreporting of adverse drug reactions by health workers is a major challenge in enhancing medicines safety. The aim of this study was to assess the willingness, attitude, and associated factors of healthcare providers towards ADRs reporting at Mizan Tepi University Teaching Hospital (MTUTH). Methods. A cross-sectional mixed method was conducted among healthcare providers working in Mizan Tepi University Teaching Hospital from August to September 2021. A total of 190 healthcare providers and five key informants were participated in the study. The quantitative data were collected using self-administered structured questionnaires, and for the qualitative study, data from the key informant interviews were collected using a semistructured questionnaire containing open-ended questions. The collected data were coded, entered, and analyzed using a Statistical Package for Social Sciences (SPSS, version 21). Furthermore, the logistic regression model was fitted to see the association between attitude items and demographic characteristics. Variables with value <0.05 were considered as statistically significant. Analysis of the qualitative data was done by sorting the data into categories and examining the emerging themes. Results. The majority of individuals in the study (81.6%) were willing to report adverse drug reactions. High percent (57.9%) of the study participants knew how to report ADR to responsible body and 66 (34.7%) of the study participants believe that ADR reporting is the responsibility of all healthcare professionals. 86 (45.3%) of respondents encountered ADR cases during their professional career. It was found that the majority of participants (53.7%) had a positive attitude toward ADR reporting. The professional distribution and work experiences of healthcare professionals had a significant impact on their attitude toward ADR reporting (). Conclusion. A large percentage of study subjects were willing to report adverse drug reactions to the appropriate authorities. The majority of healthcare providers were found to have a good attitude towards ADR reporting. Professional distribution and work experiences were significantly associated with attitude of healthcare providers towards ADR reporting. In order to improve the ADR reporting practices of the healthcare professionals and increase the ADR reporting load at the national level, the national regulatory body should collaborate with health facilities.

Sweat Cortisol and Cortisone Determination in Healthy Adults: UHPLC-MS/MS Assay Validation and Clinical Application

A simple and effective ultra-high-performance liquid chromatography assay linked to tandem mass spectrometry (UHPLC-MS/MS) for measuring cortisol and cortisone levels in human sweat has been developed and validated. A noninvasive world standard sweat collecting equipment was utilized to collect samples. The samples were analyzed using an Atlantis dC18 (2.1 × 100 mm, 3 μm) column with a 2 mM ammonium acetate and acetonitrile (1 : 1, v : v) mobile phase. In an isocratic condition, the mobile phase was delivered at a flow rate of 0.3 ml/minute. A positive electrospray ionization interface with multiple-reaction monitoring mode was used to provide simultaneous quantification of cortisol, cortisone, and internal standard at transitions of 363.11 to 121.00, 361.18 to 163.11, and 367.19 to 121.24, respectively. The method was validated for cortisol and cortisone determination over a concentration range of 0.5–50 ng/mL The detection limits for cortisol and cortisone in human sweat were 0.3 and 0.2 ng/ml, respectively. The interday coefficients of variation of cortisol and cortisone were ≤8.5% and ≤10.01%, whereas bias was in the range from −7.9% to 2.1% and from −4.3% to 3.0%, respectively. The assay was successfully applied to evaluate the cortisol-to-cortisone ratio in sweat samples collected from healthy adult volunteers.

Solubility Enhancement of a Poorly Water-Soluble Drug Using Hydrotropy and Mixed Hydrotropy-Based Solid Dispersion Techniques

Purpose. The biopharmaceutics classification system places rosuvastatin calcium in class II has a low and fluctuating oral bioavailability. The research focus is to maximize rosuvastatin calcium solubility in water and dissolution rate by employing and combining various hydrotropic agents to make a solid dispersion using solvent evaporation techniques. Methodology. The experimental study was conducted at Duhok University, College of Pharmacy. Initially, assess rosuvastatin’s solubility in hydrotropic agents including urea, mannitol, citric acid, sodium benzoate, and sodium salicylate at concentrations of 10, 20, 30, and 40% w/v. Then, various ratios of 2 and 3 hydrotropic agents were employed to reduce the concentration of each hydrotropic agent. By using a solvent evaporation procedure, solid dispersions were made. The solid dispersion powders underwent evaluation for their percentage drug content, percentage yield, solubility, dissolution test, XRD, DSC, SEM, and FTIR. For statistical analysis, GraphPad InStat Demo software was used to conduct a two-way analysis of variance (ANOVA). Results. In comparison to the pure drug, the solubility of hydrotropic solid dispersions and physical mixtures of rosuvastatin with a combination of hydrotropic agents (sodium salicylate, sodium benzoate, and urea) in the ratio of 13.33 for each increased in all formulations significantly, and all manufactured formulations’ drug release ranged from 98.83 to 104.78%, indicating a noticeably higher dissolution rate. Conclusion. The concept of mixed hydrotropic solid dispersion was shown to be an original, risk-free, and cost-effective method for enhancing the bioavailability of drugs that have a low degree of solubility in water.

Artocarpus hirsutus Lam Leaf Extract-Evaluation of Analgesic and Anti-Inflammatory Activity

The study involved extraction, identification, and evaluation of pharmacological activities of the phytochemicals present. Artocarpus hirsutus Lam, commonly known as Wild jack is a greatly valued medicinal plant, which belongs to the plant family Moraceae. Preliminary phytochemical screening studies indicated the presence of flavonoids, saponins, tannins, glycosides, and alkaloids. This study estimated the analgesic and anti-inflammatory prospective of ethanolic leaf extract of Artocarpus hirsutus Lam. The findings showed that at various doses of 100, 200, and 400 mg/kg body weight when administered orally to rats, analgesic effects were produced, also the anti-inflammatory effect studied by carrageenan-induced rat paw edema test showed major anti-inflammatory action. The result indicates that the leaf extract of Artocarpus hirsutus Lam possesses major analgesic and anti-inflammatory activity and therefore requires further investigations to better understand the mechanism of action.

Cytotoxic and Antioxidant Properties of Natural Bioactive Monoterpenes Nerol, Estragole, and 3,7-Dimethyl-1-Octanol

The therapeutic potential of medicinal plants is noted because of the presence of varieties of biochemicals. The monoterpenes, like nerol, estragole, and 3,7-dimethyl-1-octanol, have been reported for antimicrobial, antifungal, anthelmintic, and antioxidant activities. This study evaluated the toxic, cytotoxic, and oxidant/antioxidant effects of these compounds by several in vitro (DPPH and ABTS radical scavenging, and ferric reducing potential), ex vivo (hemolysis), and in vivo (Artemia Salina and Saccharomyces cerevisiae) assays. Results suggest that estragole and 3,7-dimethyl-1-octanol at 31.25–500 μg/mL did not exhibit significant cytotoxic effects in the A. Salina and hemolysis tests. Nerol showed significant cytotoxic effects on these test systems at all test concentrations. The monoterpenes showed radical (ABTS•+ and DPPH) scavenging capacities in a concentration-dependent manner in vitro tests. However, they did not oxidize the genetic material of S. cerevisiae (SODWT, Sod1Δ, Sod2Δ, Sod1/Sod2Δ, Cat1Δ, and Cat1Δ/Sod1Δ) lines. Among the three monoterpenes, nerol may be a good candidate for antioxidant and anti-tumor therapies.

Molecular Docking and Dynamics Simulation of Several Flavonoids Predict Cyanidin as an Effective Drug Candidate against SARS-CoV-2 Spike Protein

The in silico method has provided a versatile process of developing lead compounds from a large database in a short duration. Therefore, it is imperative to look for vaccinations and medications that can stop the havoc caused by SARS-CoV-2. The spike protein of SARS-CoV-2 is required for the viral entry into the host cells, hence inhibiting the virus from fusing and infecting the host. This study determined the binding interactions of 36 flavonoids along with two FDA-approved drugs against the spike protein receptor-binding domain of SARS-CoV-2 through molecular docking and molecular dynamics (MD) simulations. In addition, the molecular mechanics generalized Born surface area (MM/GBSA) approach was used to calculate the binding-free energy (BFE). Flavonoids were selected based on their in vitro assays on SARS-CoV and SARS-CoV-2. Our pharmacokinetics study revealed that cyanidin showed good drug-likeness, fulfilled Lipinski’s rule of five, and conferred favorable toxicity parameters. Furthermore, MD simulations showed that cyanidin interacts with spike protein and alters the conformation and binding-free energy suited. Finally, an in vitro assay indicated that about 50% reduction in the binding of hACE2 with S1-RBD in the presence of cyanidin-containing red grapes crude extract was achieved at approximately 1.25 mg/mL. Hence, cyanidin may be a promising adjuvant medication for the SARS-CoV-2 spike protein based on in silico and in vitro research.
