Magnusson","doi":"10.4236/PP.2021.121002","DOIUrl":"https://doi.org/10.4236/PP.2021.121002","url":null,"abstract":"Introduction: The inflammatory mechanisms of COVID-19 suggest that corticosteroids may \u0000be beneficial, but their benefits must outweigh their potential risks. The \u0000RECOVERY trial results suggest that dexamethasone 6 mg/day (but not other steroids) may confer mortality \u0000benefits on ventilated COVID-19 patients. Methods: This is a narrative review of the literature about the use of ciclesonide \u0000and dexamethasone for COVID-19 patients. Literature is being created rapidly \u0000and this review is offered as a state-of-the-science narration. Results: The SARS-CoV-2 virus is an RNA virus whose RNA is transcribed via open \u0000reading frames, making its elimination difficult. Coronaviruses have evolved \u0000multiple strategies for proteolytic activation of the spike; viral replication \u0000occurs entirely in the cytoplasm. In this connection, the RNA-cleaving \u0000endoribonuclease (NSP-15 also known as EndoU) may play a key role by facilitating \u0000viral double-stranded RNA recognition by the host’s macrophages. Furthermore, the virus is able to undergo RNA \u0000recombination rapidly, enabling it to evade host immunity and develop \u0000drug resistance. Ciclesonide is an inhaled corticosteroid that reduces lung \u0000inflammation and blocks the activity of specific kinases which may explain its \u0000anti-inflammatory effect. Dexamethasone is known to reduce mortality in \u0000ventilated COVID-19 patients. Discussion: Systemic corticosteroids were used in previous coronavirus epidemics \u0000(SARS and MERS) and pulmonary histology of these patients is similar to those \u0000in COVID-19 patients. Acute respiratory distress syndrome is the main cause of \u0000death in most COVID-19 infections and steroids may be effective in addressing \u0000that condition, brought on by cytokine storm. However, it should be noted that \u0000inhaled steroids likely have a narrower window for effect than systemic \u0000regimens. Conclusion: Dexamethasone has been proven to confer mortality benefits on ventilated \u0000COVID-19 patients and may be used with inhaled ciclesonide, which has few side \u0000effects and can be locally metabolized. Further study is needed.","PeriodicalId":19875,"journal":{"name":"Pharmacology & Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85315657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bitterness intensities of dry syrups mixed with various beverages were also evaluated using the taste sensor. Twenty dry-syrup formulations of antibacterial and anti-allergic drugs containing bitter active ingredients, frequently used in pediatric medicine in Japan, were selected for testing. The main factors influencing palatability were determined by factor analysis of data from human gustatory sensation testing using the semantic differential method. It was shown that the bitterness intensity of dry syrups in water could be predicted by the artificial taste sensor. The influence of different beverages (orange juice, milk or cocoa) mixed with the dry syrups was evaluated using the artificial taste sensor. Taste and texture were found to be the principal factors influencing the palatability of dry syrups. While the bitterness intensities of some dry syrups were increased by mixing with orange juice, the bitterness intensities of most dry syrups were decreased by mixing with milk or cocoa. This suggests that one or more constituents of milk or cocoa may reduce the bitterness intensities of dry syrups.","PeriodicalId":19875,"journal":{"name":"Pharmacology & Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74401072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Supplements are becoming popular as they can be purchased easily. In Japan, the “Food with Function Claims” system began in 2015; the market for supplements is expected to continue to expand. However, the use of some supplements has not been supported with sufficient scientific evidence; some products have even caused health problems. In addition, consumers may not be able to make correct decisions based on the information from the Internet. Unlike medicine, the instruction on the usage of supplements is not precise. Therefore, improving the quality of the information on the supplements will become more necessary in the future. This study aims to improve the quality of the information on supplements by surveying the disintegration and dissolution behavior of the carnitine-containing supplements and evaluated their quality. The products tested here were supplements containing commercial carnitine. Disintegration test and dissolution test were conducted according to the Japanese Pharmacopoeia. Carnitine was quantified by high-performance liquid chromatography. The disintegration tests revealed that the products had different disintegration times, varying from 35 to 100 minutes; some products took more than 5 hours to disintegrate. Thus, some products had a slow rise in their dissolution rate. These results suggest that the carnitine-containing supplements used in this study may affect the absorption process. Therefore, in the case of oral administration, the expected effect might not be achieved depending on the product.","PeriodicalId":19875,"journal":{"name":"Pharmacology & Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80951607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
