Evaluation of Sweet Orange (<i>Citrus sinensis</i>) Waste-Derived Pectin as a Sustained Release Excipient in Matrix Tablets of Nifedipine https://www.ajol.info/index.php/epj/article/view/275323 <p>Pectin is a natural polymer that has a wide range of pharmaceutical applications including in controlled drug delivery. The annual orange&nbsp; production of Ethiopia is reported to be about 26,000 tons in 2022. From this amount, the peels account for 30 - 40% of the total weight of&nbsp; the fresh fruit which are damped as a waste material resulting in ecological and economic burden of disposing the accumulated waste&nbsp; products. This waste material can be converted to 590 - 780 tons of pectin annually, generating a huge sum of money. The objective of&nbsp; this research work was to isolate and characterize the physicochemical properties of orange peel (<em>Citrus sinensis</em>) waste-derived pectin as&nbsp; a matrix-forming polymer for sustained release tablet formulations using nifedipine as a model. Pectin was extracted from the dried&nbsp; orange peel powder by acidified hot water extraction method. The extracted pectin was found to be a non-free-flowing, poorly compressible powder with a degree of methyl esterification of 39% and is classified as low methoxy pectin. The galacturonic acid (GalA)&nbsp; content of the extracted pectin was found to be 90 ± 2%. Pectin-based matrix tablets of nifedipine were prepared by the non-aqueous wet&nbsp; granulation method with and without incorporating zinc chloride and calcium chloride and showed successful sustained release&nbsp; effect. The weight variation, hardness, friability, tensile strength, and disintegration time of the formulations were within acceptable&nbsp; ranges. The formulated matrix tablets sustained the drug release for more than 12 h. At equal concentrations, zinc pectinate showed a&nbsp; better sustaining effect than calcium pectinate. The drug release data were fitted into different release kinetics models and the Hixson- Crowell model best fitted the release data. In conclusion, Citrus sinensis peel waste-derived pectin can be employed as a safe natural&nbsp; excipient in a sustained drug delivery system.&nbsp;</p> Bedilu Amare Yonas Brhane Anteneh Belete Copyright (c) 2024 2024-07-31 2024-07-31 38 1 1 16 Comparative <i>in vitro</i> Quality Evaluation of Four Brands of Atenolol Tablets Available in Addis Ababa, Ethiopia https://www.ajol.info/index.php/epj/article/view/275324 <p>The circulation of substandard medicines remains a serious problem in resource-limited countries in subSaharan Africa, where most of the drugs available are imported. Antihypertensive drugs are one of the drug categories with numerous brands having significant price&nbsp; variations. Therefore, it is essential to compare and evaluate the bioequivalence of such drugs. The aim of the present study was to&nbsp; evaluate the physicochemical quality attributes and in vitro equivalence of four brands of atenolol tablets available in different retail&nbsp; outlets in Addis Ababa, Ethiopia. Four brands of atenolol 50 mg tablets were purchased from different community pharmacies in Addis&nbsp; Ababa, and were randomly coded as brand A, B, C, and D. Physicochemical quality control parameters of tablets such as tablet hardness,&nbsp; friability, weight variation and disintegration time were evaluated. Dissolution profile and active pharmaceutical ingredient (API) content&nbsp; was also determined by UV absorption spectrophotometry. The study revealed that all the studied brands meet official pharmacopoeial&nbsp; requirements of weight variation, hardness, thickness, friability, disintegration and dissolution profile. On the other hand, the API content&nbsp; of all the brands except D (118.30%) complied with the limit of USP. In water medium, disintegration time of the sample tablets ranged from 1.82 ± 0.47 to 16.95 ± 0.88 min and all the brands released &gt;85% of the label claim within 15 min. Hence, all the studied&nbsp; brands except D can be considered as pharmaceutically equivalent and could be prescribed interchangeably.&nbsp;</p> Abebe Birsew Sofia Seid Muluwork Sahile Copyright (c) 2024 2024-07-31 2024-07-31 38 1 17 24 Standardization Methods for the Roots of <i>Echinops kebericho</i> Mesfin: An Endemic Medicinal Plant of Ethiopia https://www.ajol.info/index.php/epj/article/view/275325 <p><em>Echinops kebericho</em> Mesfin is one of the most important medicinal plants of Ethiopia with a long traditional use against a range of&nbsp; ailments. The major limitation to the use of herbal medicines such as <em>E. kebericho</em>, however, is the absence of quality control parameters.&nbsp; The present study aims to standardize the roots of <em>E. </em><em>kebericho</em> using samples collected from two different geographical locations. The&nbsp; standardisation was validated by using standard protocols such as microscopy, physicochemical parameters, chemo profiling with liquid chromatography-quadrupole time of flight-mass spectrometry (LC-QTOF-MS), gas chromatography-mass spectrometry (GC-MS), and&nbsp; spectroscopic methods using fourier transform infrared spectroscopy (FTIR). Microscopically, the transverse section of the root showed&nbsp; vascular cambium and secondary xylem, while the longitudinal view of the root displayed vascular cambium. LC-QTOF-MS and GC-MS&nbsp; analyses identified 16 and 40 compounds, respectively. The major constituents identified in the studied extracts were selected as marker&nbsp; compounds. Thus, pyrocurzerenone and lappaconitine which were identified in the 80% methanol extract by LC-QTOF-MS, and&nbsp; dehydrocostus lactone and dihdrodehydrocostus lactone detected in the n-hexane extract by GC-MS analysis were used as marker&nbsp; compounds. IR spectral analysis further indicated that the rootextractsof <em>E. kebericho</em> are rich in terpenoids. These parameters&nbsp; describesome physicochemical features of <em>E. kebericho</em>, which can be useful in its quality control and safe use. Furthermore, results from&nbsp; the chemo-profiling could help in the isolation of medicinally significant compounds.&nbsp;</p> Awraris Anbasie Tarekegn Birhanu Frehiwot Teka Mariamawit Yonathan Yeshak Copyright (c) 2024 2024-07-31 2024-07-31 38 1 25 44 The Pattern of Dyslipidemia and its Associated Factors among Recently Diagnosed Patients with Type 2 Diabetes Mellitus at Saint Paul Hospital Millennium Medical College, Addis Ababa, Ethiopia: A Comparative Cross Sectional Study https://www.ajol.info/index.php/epj/article/view/275326 <p>Dyslipidemia which is a common phenomenon in type-2 diabetes mellitus (T2DM) patients, significantly increases cardiovascular events.&nbsp; In this study, the prevalence and pattern as well as possible risk factors of dyslipidmia in Ethiopian patients recently diagnosed with T2DM&nbsp; was determined. This hospital-based crosssectional study enrolled 127 patients with T2DM from a tertiary referral hospital, St.&nbsp; Paul’s Hospital Millennium Medical College (SPHMMC), Addis Ababa, Ethiopia. A semi-structured questionnaire was used to obtain&nbsp; demographic and cardio-metabolic risk factors while information on comorbidities, full fasting lipid profile, fasting blood glucose, and&nbsp; glycated hemoglobin A1c were abstracted from the medical charts. Dyslipidemia was defined according to the Third Report of the&nbsp; National Cholesterol Education Programme (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in&nbsp; Adults criteria, while elevated levels of non-HDLc was defined as non-HDLc levels ≥ 130 mg/dl. A Chi-square test, student’s t-test and&nbsp; Kruskal-Wallis test were used accordingly. Multivariate logistic regression analyses were performed to determine factors associated with&nbsp; component lipid abnormalities. The prevalence of dyslipidemia in T2DM patients was 92.1%. There was no significant difference in the&nbsp; prevalence of dyslipidemia between the female and male sexes (95.12 % vs. 86.67 %, p = 0.17), although the prevalence of individual lipid&nbsp; abnormality varied with gender. The prevalence of high total cholesterol, high triglycerides, low HDLc and high LDLc was 28.35%, 52.76%,&nbsp; 64.57%, and 69.29%, respectively. The prevalence of low HDLc (p = 0.002) and high LDLc (p = 0.037) was significantly higher among&nbsp; females than males, though the difference was barely significant for high total cholesterol (p = 0.05). The prevalence of mixed&nbsp; atherogenic dyslipidemia, combined dyslipidemia and isolated dyslipidemia was 37 (29.1%), 34 (26.8%), and 27 (21.3%), respectively. The&nbsp; mixed atherogenic dyslipidemia was the most common pattern of dyslipidemia (37, 29.1%), with the proportion being higher in women&nbsp; than in men (36.6% vs. 15.6%, p = 0.013). The female gender, age less than 50 years, and not being on statin treatment, physically inactive,&nbsp; not being hypertensive, and being on metformin + insulin regimen were significantly associated with different component lipid abnormalities in patients with T2DM. The study indicated a high prevalence of dyslipidemia in patients with T2DM attending clinic at&nbsp; SPMMCH with atherogenic mixed dyslipidemia being the commonest pattern. This implies that most of the T2DM patients are at a higher&nbsp; risk of cardiovascular disease. Therefore, it is mandatory to screen, implement routine treatments, and educate diabetic patients about&nbsp; diabetic dyslipidemia and its associated risk factors.&nbsp;</p> Abraham Degaga Sisay Sirgu Hasniza Zaman Huri Birhanemeskel Tegene Ephrem Engidawork Workineh Shibeshi Copyright (c) 2024 2024-07-31 2024-07-31 38 1 45 60 Thromboembolism Risk and Management in Hospitalized COVID-19 Patients: A Single-Center Experience in Ethiopia https://www.ajol.info/index.php/epj/article/view/275327 <p>COVID-19 predisposes patients to venous thromboembolism (VTE) due to excessive inflammation, hypoxia, immobilization, diffuse&nbsp; intravascular coagulation (DIC), and pulmonary thrombotic microangiopathy. COVID-19 patients who developed VTE were at a higher risk&nbsp; of developing complications and death than those who did not. This study aimed to evaluate the risk, incidence, and management of&nbsp; VTE in hospitalized COVID-19 patients at Tikur Anbessa Specialized Hospital (TASH), Addis Ababa, Ethiopia. A crosssectional&nbsp; retrospective study was conducted among 146 COVID-19 patients admitted to TASH. The modified Caprini risk score was used to assess&nbsp; the risk of VTE in COVID-19 patients. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 25. Of the 146&nbsp; patients included in the study, 84 (57.53%) were males and the age was between 18 and 89 (mean 45.56 ± 18.17) years. More than one- third of the patients (69.2%) had a ≥ 5 VTE risk score for developing VTE, with a mean score of 3.63 ± 0.60. The most frequently observed&nbsp; VTE risk factors were symptomatic COVID-19 (88.40%), serious lung disease (56.2%), and age &gt; 40 years (52.10%). Thromboprophylaxis&nbsp; was prescribed to 98 patients (67.12 %). The incidence of VTE was 15.75%, and most patients (91.3%) had the highest VTE risk (score ≥ 5).&nbsp; It can be concluded that all patients with COVID-19 were at risk of developing VTE, with low utilization of thromboprophylaxis. The&nbsp; incidence of VTE was high and majorly occurred in patients who did not receive prophylaxis. Radiological methods should be used to&nbsp; diagnose VTE for optimizing its diagnosis and management.</p> Ashenafi Teklu Alfoalem Araba Abiye Minyahil Alebachew Woldu Gobezie Temesgen Tegegne Tamrat Assefa Tadesse Copyright (c) 2024 2024-07-31 2024-07-31 38 1 61 68 Knowledge and Practice of Community Pharmacy Professionals on Medication Safety during Pregnancy in Addis Ababa, Ethiopia https://www.ajol.info/index.php/epj/article/view/275328 <p>Community pharmacists, the most&nbsp; ccessible healthcare professionals and&nbsp; experts in medicine should have relevant and updated&nbsp; knowledge and skills regarding dispensing medicines during pregnancy. The purpose of this study was to assess the knowledge and&nbsp; practice of community pharmacy professionals regarding medication safety during pregnancy in Addis Ababa, Ethiopia. A cross-sectional&nbsp; study using a semistructured questionnaire was conducted among 117 community pharmacy professionals working in community&nbsp; pharmacies and drug stores in the Lideta sub-city, Addis Ababa, Ethiopia. The lists of medicines were prepared based on the US FDA drug&nbsp; risk category (A, B, C, D, and X) during pregnancy, and then revised and validated by an expert pharmacist working in the community&nbsp; pharmacy and a senior clinical pharmacist practicing in a university teaching hospital. Data were analyzed using SPSS version 26. All participants provided verbal informed consent prior to participating in the study. Most of the respondents [80 (68.4%), 90 (77.8%), and 90&nbsp; (77.8%)] knew that amoxicillin was safe in all three trimesters. Only approximately one-third of the pharmacy professionals believed that&nbsp; budesonide inhalers were safe during all pregnancy periods. Regarding knowledge of the safety of over-the-counter drugs, 77.8% and&nbsp; 59.8% identified acetaminophen and ibuprofen as safe and unsafe, respectively, during the third trimester. Approximately 78.6% of the&nbsp; respondents were asked about the pregnancy status of women of reproductive age and advised pregnant women about over-the- counter drugs (65.8%) and herbal medicines (23.9%) that should not be taken during pregnancy. The overall knowledge score on&nbsp; medication safety during pregnancy was 59.8%, and 51.3% of community pharmacists followed safe practices while dispensing medicines&nbsp; to pregnant women. Approximately 80.3% of the respondents updated their knowledge regarding the safety of medications during&nbsp; pregnancy. The overall knowledge of medication safety during pregnancy by community pharmacy professionals is suboptimal, and&nbsp; there are gaps and variations in the knowledge and practice of medication safety during pregnancy, which mandates in-service training&nbsp; programmes to provide better dispensing quality services for pregnant women based on correct and evidence-based information.&nbsp;</p> Mekdes Worku Tamrat Assefa Tadesse Atalay Mulu Fentie Dawit Teshome Gebregeorgise Copyright (c) 2024 2024-07-31 2024-07-31 38 1 69 76
