Orally disintegrating drug delivery is currently the gold standard in the pharmaceutical industry where it is regarded as the fastest, safest, convenient, and most economic method of drug delivery having the highest patient compliance and preferred over conventional tablets. The goal of this study was to formulate and evaluate oral disintegrating tablets (ODTs) of Metoclopramide hydrochloride to overcome swallowing difficulties. The key to developing successful ODT formulation by direct compression method is to select the right super disintegrant. Nine formulations were prepared using different super disintegrants such as sodium starch glycolate (SSG), croscarmellose sodium (CCS), and crospovidone (CP) at three concentrations i.e. 2.8 %, 4 %, and 4.8 %. The formulation was evaluate for pre and post-compression parameters like angle of repose, compressibility index, Hausner's ratio, uniformity of content, thickness, hardness, friability, drug content, wetting time, water absorption ratio, dispersion time, in-vitro disintegration time etc. Results revealed that among the 9 formulations, the formulation MHF9 containing 4.8 % of crospovidone was selected as the best formulation as its wetting time 28 second, disintegration and dispersion time 7 second and 18 seconds, percentage drug release after 15 minutes was 102.52 %.
Background Natural bioactive components derived from plant secondary metabolites have been pronounced as valuable alternatives for anticipating and subsiding hepatotoxic effects and its chronic complications based on experimental verification. The focus of this review is to elucidate the commonly used modern medicine for the treatment of liver disease and how major phytoconstituents have been tested for hepatoprotective activity, mechanism of action of some promising agents from natural sources, and clinical trial data for treating in patients with different liver diseases by the aid of natural phytoconstituents. Main text The review shows fifteen major isolated phytoconstituents, their biological sources, chemical structures, utilized plant parts, type of extracts used, hepatoprotective assay method, and their possible mechanism of action on the hepatoprotection. Nine promising hepatoprotective leads from natural sources with their chemistry and hepatoprotective mechanism are mentioned briefly. The review further includes the recent clinical trial studies of some hepatoprotective leads and their clinical outcome with different liver disease patients. Scientific studies revealed that antioxidant properties are the central mechanism for the phytoconstituents to subside different disease pathways by upsurging antioxidant defense system of cells, scavenging free radicals, down surging lipid peroxidation, improving anti-inflammatory potential, and further protecting the hepatic cell injury. In this review, we summarize recent development of natural product-based hepatoprotective leads and their curative potential for various sort of liver diseases. Furthermore, the usefulness of hit and lead molecules from natural sources for significant clinical benefit to discover new drug molecule and downsizing the problems of medication and chemical-induced hepatotoxic effects is extrapolated. Conclusion Further research are encouraged to elucidate the pharmacological principle of these natural-based chemical agents which will stimulate future pharmaceutical development of therapeutically beneficial hepatoprotective regimens.
Background: COVID-19 has become a great public health concern in the world. In this unbridled situation, most of the educational institutes have been closed as a result. Education sector suffers the worst during this period as it fails to get the real priority of the government. Aim: This study aims to assess the psychological impact, behavioral changes, and perception of the COVID-19 pandemic on health science students of Nepal. Methods: A web based online questionnaire that includes General Anxiety Disorder (GAD-7) was used among 765 participants in between August and September 2020. A chi square test was used to test the association between variables. Results: The prevalence rate of moderate and severe anxiety was 16.1%. Surprisingly, participants with different ethnicity, study program, university affiliation, symptoms related to COVID-19, confirmed or suspected case, living status were associated with the anxiety level (p<0.05). The majority of the participants were engaged in all recommended and avoidance behaviors. Majority of the participants have right perception about hand washing frequency, wearing face mask, avoid going out that can reduce the risk of catching COVID-19. Awareness of corrected hand hygiene practice was 20.4%. Conclusions: The awareness of correct hand washing practice is less optimal, increase anxiety levels and changes behavioral responses to COVID-19 have been dramatic during the rising phase of the outbreak. These findings will help the concerned authorities to make the necessary policies and strategies in order to improve the mental health of the participants.
<p class="abstract"><strong>Background:</strong> Urinary tract infection (UTI) is the most common infection caused by the presence and growth of pathogenic microorganisms within the human urinary system into the lower and upper genito-urinary tract. UTI continues to be major health problems in developing countries like Nepal.</p><p class="abstract"><strong>Methods:</strong> A prospective observational study was conducted from June 2019 to November 2019 in the outpatient and inpatient department of Manipal teaching hospital. The face-to-face interview was adopted in 137 UTI patients with the census sampling technique. </p><p class="abstract"><strong>Results:</strong> A total of 137 patients (121 out-patients and 16 in-patients), 82 (59.85%) female, and 55 (40.15%) males were enrolled in which UTI was observed in more than half of the sample in the aged group of 25-54. <em>Escherichia coli</em> was the most common uropathogens isolated whereas dysuria was the most common presenting symptom among the patients. Cefixime 200 mg followed by nitrofurantoin 100 mg was the most commonly prescribed medicine for UTI. Disodium hydrogen 1.40 g oral liquid, pantoprazole 40 mg tablet, and multivitamins were commonly prescribed supportive medications. The empirically prescribed average cost was Nepalese rupee (NRs.) 820.44 whereas the total definitive average cost was NRs. 305.54. The average cost of medical management for in-patients was NRs. 2316.55 including registration, urine analysis, investigation bed charge, and other consumable charges as well as discharge medicine cost.</p><p class="abstract"><strong>Conclusions:</strong> With lower cost, higher sensitivity, and high prescription, cefixime, and nitrofurantoin could be better drugs for the management of UTI among outpatient department (OPD) patients while ceftriaxone could be better for in-patients.</p><p> </p>
