Assessment of knowledge, attitude and practice of over-the-counter drugs and dietary supplements among non-healthcare college students in Chitradurga
Get PDFBackground: The market for OTC drugs and dietary supplements is rapidly growing. However, there exists a lack of adequate awareness among the general public regarding the advantages and potential drawbacks associated with these products, particularly among the younger generation, who heavily rely on the internet for information. Therefore, this study sought to assess the knowledge, attitude and practice of college students regarding OTC drugs and dietary supplements, including prevalence and associated factors.
Methods: A prospective interventional study with 306 participants was conducted. Data were collected using a self-designed and pre-validated questionnaire and analysed using Statistical Package for the Social Sciences (SPSS) version 28. Descriptive and inferential (T-test) statistics were use.
Results: The prevalence of usage of OTC drugs and DSs was found to be 98.4% and 61.4% respectively. Easy accessibility (42.2%), safe and well tolerable (32.5%) were the main factors that influenced them to turn to SM with OTC drugs. The respondent’s preference for DSs was primarily driven by their desire to maintain good health (33.6%). Internet (22.2%) and healthcare professionals (21.9%) were the two most reported sources that students relied on to obtain information about DSs. The result revealed poor knowledge and a positive attitude towards OTC drugs and DSs among all participants.
Conclusions: A high prevalence of self-medication with OTC drugs and dietary supplements use was highlighted. Notable issues and improper practices were recognized. The findings indicate a need for education to enhance knowledge about OTC drugs and DSs and to encourage safe practices
Assessment of knowledge, attitude and practices of generic drugs and their potential nocebo effects among second year medical students in a rural tertiary care teaching hospital: a cross-sectional study
Get PDFBackground: As drugs contribute significantly to healthcare costs, reduction in their cost by using generics offers a significant advantage so evaluation was done of knowledge, attitude, and practices of generic drugs and their potential nocebo effects among second year medical students in a tertiary care teaching hospital.
Methods: A prospective, observational, and questionnaire-based study was conducted after approval by the Institutional Ethics Committee. Pretested and validated questionnaire consisting of 26 questions about generic drugs was filled by 92 participants. The filled questionnaires were collected and analyzed on Microsoft Excel sheet.
Results: Majority (90.2%) students had heard about generic drugs, however, only 18.5% students thought there was a nocebo effect associated with the use of generic drugs. Majority of the study population had a positive attitude towards use of generic drugs and believed them to be equally efficacious as branded drugs in addition to not having more side effects than branded drugs, though their current practices did not reflect this knowledge and attitude. 63% also said that following this study, they were likely to prescribe or consume generics as future doctors and patients.
Conclusions: The participants had sufficient knowledge and positive attitude towards use of generic drugs. Knowledge regarding the possible nocebo effects of generic drugs was lacking
Combination of purple sweet potato (Ipomoea batatas L.) leaf extract with metformin on blood glucose and total cholesterol levels of albino rats induced by high-fat diet and streptozotocin
Get PDFBackground: Diabetes mellitus is a metabolic disease characterized by hyperglycemia due to impaired insulin secretion, often accompanied by hypercholesterolemia. Metformin is a first-line antihyperglycemic drug that is often combined with other antihyperglycemic drugs. Purple sweet potato leaves have been widely studied to reduce glucose and cholesterol levels.
Methods: This study was an experimental study using rats induced with a high-fat diet and streptozotocin, which were divided into 8 treatment groups, namely groups given CMC Na 0.5%, Metformin 45 mg/kg BW, Purple Sweet Potato Leaf Extract (SPLE) 200 mg/kg BW, SPLE 400 mg/kg BW, SPLE 800 mg/kg BW, SPLE 200 mg/kg BW with metformin 45 mg/kg BW, SPLE 400 mg/kg BW with metformin 45 mg/kg BW, and SPLE 800 mg/kg BW with metformin 45 mg/kg BW.
Results: After treatment for 28 days with SPLE doses of 200 mg, 400 mg, and 800 mg/kg BW, both single doses and combinations with metformin showed a decrease in fasting blood glucose levels and total cholesterol, which were statistically significantly different (p<0.05) between treatment groups using the one-way ANOVA. The combination of SPLE 800 mg/kg BW with metformin normalized blood glucose levels of 93.50±4.93 mg/dl.
Conclusion: The combination of purple sweet potato leaf extract with metformin is more effective in reducing blood glucose and total cholesterol levels compared to the single administration of metformin and SPLE
Pharmacokinetics of amphotericin B after accidental overdose in an adult critically ill patient treated with plasmapheresis: a case report and review of literature
Get PDFAmphotericin B is a broad-spectrum antifungal agent that is used in the treatment of systemic fungal infections. We describe the case of a 62-year-old female patient with recent aneurysmal subarachnoid hemorrhage who was treated for suspected ventriculitis and a fungal coinfection. Instead of liposomal amphotericin B (L-AmB), 465 mg (5 mg/kg) amphotericin B deoxycholate (DOC) was inadvertently administered, leading to refractory shock with multiple organ failure and requiring mechanical ventilation. Since an overdose of amphotericin B can lead to fatal consequences and has a half-life of 15 days, plasmapheresis was started. The serum concentration decreased from 1.32 µg/mL to 0.62 µg/mL before plasmapheresis, demonstrating a mean half-life of 49 hours. After two plasmapheresis sessions, the serum concentration further dropped to 0.26 µg/mL, demonstrating a mean half-life of 17 hours. In contrast, the third plasmapheresis session had no effect on serum concentration. The patient made a full recovery, potentially facilitated by enhanced amphotericin B elimination through plasmapheresis. Positive outcomes were previously reported in two adult patients treated with plasmapheresis. However, other reports without plasmapheresis described fatal outcomes in adult patients, albeit with a twofold overdose compared to the two patients successfully treated with plasmapheresis. Moreover, plasmapheresis itself carries risks such as hypocalcemia, metabolic alkalosis, and coagulation deficits. Consequently, the role of plasmapheresis in amphotericin B overdose is still debated
Case report on anti-tuberculosis drug-induced hepatitis and pancreatitis
Get PDFTuberculosis (TB) is a widespread infectious disease primarily impacting the lungs but with potential effects on various organs, such as bones, kidneys, and intestines. This case underscores a rare yet serious complication associated with anti-TB drug (ATD) treatment-the development of drug-induced acute pancreatitis. In this instance, a 65-year-old male undergoing ATD therapy exhibited symptoms including fever, vomiting, and fatigue. Despite receiving medical intervention, including intravenous antibiotics and hepatoprotective drugs, the patient's condition progressively worsened, ultimately resulting in a fatal outcome. This case emphasizes the crucial significance of early identification and effective management of such complications, highlighting the necessity for vigilant monitoring and regular assessment of liver function tests throughout ATD treatment
Knowledge, attitude and practices regarding antimicrobial use and resistance among community members of Mtendere Township in Lusaka, Zambia: findings and implications on antimicrobial stewardship
Get PDFBackground: Antibiotic resistance is a public health problem affecting all countries and leads to an increase in morbidity and mortality rates. In Zambia, there is little information on the knowledge, attitude, and practices of community members about antibiotic use and resistance. This study assessed the knowledge, attitude and practices (KAP) regarding antimicrobial use (AMU) and antimicrobial resistance (AMR) among community members in Mtendere township of Lusaka Zambia.
Methods: This was a cross-sectional study that was conducted from May 2020 to August 2020 using a structured questionnaire among 369 Mtendere residents. The data were analyzed using Statistical Package for Social Sciences (SPSS) version 22.0.
Results: Of the 369 participants, 50.9% were male and 62.1% were aged between 18 and 29 years. Overall, this study found a poor KAP (38% good knowledge, 58% positive attitudes, and 52% good practices) regarding AMU and AMR. More than half of the participants 66.7% (246/369) had heard of antibiotics, 33.6% heard of AMR, and 23% heard of antimicrobial-resistant infections. Most of the participants 48.2% were not aware that AMR is a public health issue. A total of 52.8% (195/369) of the participants said they did not take antibiotics without consulting a doctor or pharmacist, translating into a prevalence of self-medication of 47.2%.
Conclusions: This study showed that Mtendere residents had poor KAP towards antibiotic use and resistance. There is a need to implement community-based interventional campaigns including antimicrobial stewardship programmes address the gaps in KAP identified in this study
A review on cardiovascular risk in rheumatoid arthritis
Get PDFA systemic inflammatory disease known as rheumatoid arthritis (RA) is distinguished by excessive cardiovascular disease (CVD) morbidity and death. Traditional CV risk factors may partially contribute to CV disease in RA. Shared inflammatory mediators, post-translational modifications of peptides/proteins and subsequent immune responses, changes in the composition and function of lipoproteins, increased oxidative stress, and endothelial dysfunction are some of the mechanisms that link RA and CVD. The detailed pathogenetic pathway by which this association between RA and CVD might be explained is still not entirely known. It is crucial for controlling cardiovascular risk in people with RA. Optimizing care of traditional risk factors in addition to those inherent to RA is necessary to lessen the burden caused by CVD. The potential effect of planned Cardiac risk management in these individuals is highlighted by findings for under diagnosis and inadequate treatment of conventional CVD risk factors in RA. Present cardiovascular standards suggest RA patients to be examined for and treated for CVD risk factors without appropriate treatment goals. Utilizing potent anti-rheumatic medications that can reduce disease activity and treating the conventional CV risk factors should both be part of the therapy of CV risk in RA. There is currently insufficient scientific data to develop therapy targets for RA-related CVD risk factors. Thus, more study is required on the traditional CVD risk factor screening and management in RA patients
Evaluation of nephrotoxicity effects of the methanol leaf extract of A. angustifolia in Wistar rats
Get PDFBackground: Agave angustifolia is a common traditional remedy in localities for disease treatment. This study focussed on evaluating the nephrotoxicity activity of the methanol extract of A. angustifolia leaf.
Methods: Twenty-five Wistar rats of both sex were randomly shared into five groups. Group 1 received 10 mL/kg distilled water, group 2 gentamicin 80mg/kg, extract groups (3, 4 and 5) were placed on 100 mg/kg, 200 mg/kg and 400 mg/kg of A. angustifolia leaf extract administered orally through an orogastric tube for 14 days. The rats were sacrificed using chloroform, and their kidneys were harvested, weighed and immediately fixed in 10% buffered formalin for histological analysis and blood samples were collected by cardiac puncture for biochemical and haematological analysis.
Results: Results showed there was no marked difference in the levels of the packed cell volume (PCV) in all the concentrations of the extract as well as the controls. The gentamicin group showed a remarkable rise in the serum urea and creatinine level when compared to both the control and extract groups. Similar effects were observed in the 100 mg/kg and 200 mg/kg of the extract. However, severe kidney injury was observed in the group treated with 400 mg/kg of the extract.
Conclusions: Despite the beneficial potential of A. angustifolia, it also exhibited toxic effects on the kidney thereby causing significant damage to the kidney morphology at higher doses. The damages inflicted in these tissues are dose-dependent. Therefore A. angustifolia should be taken in low doses within shortest period of time
Drug induced bullous fixed drug eruption: a case report
Get PDFBullous fixed drug eruption, which is a cutaneous adverse drug reaction, is commonly seen with antimicrobials and analgesics. Bullous drug eruptions are infrequent, but because they pose a challenge both to affected patients and to treating physicians, they are considered to be the most severe cutaneous adverse reactions (SCAR). It is important to recognize these conditions and to differentiate them from other clinical entities involving blister formation. There may be early signs and symptoms that indicate a severe bullous drug eruption even before blisters and erosions of the skin and mucous membranes become obvious. Once the diagnosis is suspected, appropriate diagnostic procedures and adequate management must be initiated. The latter includes identification of the potentially inducing drug, although it should be taken into account that not all cases of bullous eruptions are drug-induced. In cases with drug causality the potentially culprit agent must be withdrawn, while in cases with other aetiology the underlying condition, e.g. an infection, must be treated appropriately. In addition to best supportive care, immunomodulating therapy may be considered. Here we report 64-year-old male with bullous fixed drug eruptions due to doxycycline administration
