Of the many other options being investigated, corticosteroids are now recommended by WHO for patients with COVID‐19 requiring oxygen or higher respiratory support therapy ( WHO 2020d ), having been reported to reduce mortality in this population in a systematic review ( )

Also, hydroxychloroquine doesn't prevent infection with the virus that causes COVID-19
Poor methods and reporting
In addition, the risk for serious side effects with hydroxychloroquine and chloroquine phosphate are a concern

Furthermore, HCQ/CQ promote the production of immunosuppressive factors IL-6 and TNFα and activate p38 MAPK 3
The drug has wide-ranging drug interactions and potential cardiotoxicity
There is a need for effective treatment for coronavirus disease 2019 (COVID-19) infection
However, antiviral mechanisms of chloroquine remain speculative
It includes nirmatrelvir — a drug that blocks the activity of a specific enzyme needed for the virus that causes COVID-19 to replicate — and an antiviral drug called ritonavir that helps slow the breakdown of nirmatrelvir
Shortly after, the WHO designated COVID-19 as a global pandemic in March 2020 []
We review these studies and call for additional randomized clinical trials
, chloroquine, lopinavir/ritonavir, ribavirin, tocilizumab, and remdesivir) and increase the risk of serious adverse reactions such as QT‐prolongation With no antivirals or vaccines available for the treatment of COVID-19, the medical community is presently exploring repositioning of clinically approved drugs for COVID-19
Chloroquine phosphate is experimental because we do not know if it works for COVID-19
, will verify whether the hopes raised by chloroquine in the treatment of COVID-19 can be confirmed
Chloroquine (CQ) was initially reported to be effective against SARS-COV-2 and then Hydroxychloroquine (HCQ) followed 6
Solid black line shows the population mean exposure, and the shaded area shows the 95% prediction interval
Cohort studies that assessed the use of HCQ for COVID-19 reported conflicting results, but randomized controlled trials (RCTs) demonstrated no effect on mortality rates and no substantial clinical benefits of HCQ used either for prevention or treatment of COVID-19
This targeted update includes data from RCTs and quasi-experimental studies comparing the use of hydroxychloroquine or chloroquine (with or without a macrolide) with standard care as a treatment for COVID-19
Expert opinion considers that if chloroquine or hydroxychloroquine is effective, it may decrease symptomatic COVID-19 by 23%, and therefore, the chloroquine arm or hydroxychloroquine would have a 2
The findings from Mehra and colleagues' study add to preliminary reports Current evidence does not support treatment or prophylactic use of chloroquine or hydroxychloroquine for COVID-19 disease
The current circumstances justify prioritization of ethical review of study proposals Chloroquine (CQ) and hydroxychloroquine (HCQ) are anti-malarial and immunomodulatory drugs that have been suggested for the prevention and treatment of coronavirus disease 2019 (COVID-19) due to their in vitro antiviral activity against the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) Unfortunately, indiscriminate promotion of CQ/HCQ (with or without azithromycin) based on the aforementioned low-quality data for COVID-19 treatment has led to widespread shortages, self-use, and fatal overdoses
Purpose: To summarize evidence about the benefits and harms of hydroxychloroquine or chloroquine for the treatment or prophylaxis of coronavirus disease 2019 (COVID-19)
The antimalarials chloroquine (CQ) and its analog, hydroxychloroquine (HCQ), have been tested for COVID‐19 Recent publications have brought attention to the possible benefit of chloroquine, a broadly used antimalarial drug, in the treatment of patients infected by the novel emerged coronavirus (SARS-CoV-2) (Colson et al
1136/bmj
Cells were then infected with SARS-CoV, and virus antigens were visualized by indirect Researchers and medical practitioners worldwide have explored the use of chloroquine and hydroxychloroquine, in few occasions combined with the macrolide antibiotic azithromycin, for COVID-19 treatment
5 million people have been diagnosed with coronavirus disease 2019 (COVID-19)
Objectives: To evaluate the effects of chloroquine (CQ) or hydroxychloroquine (HCQ) for 1) treating people with COVID-19 on death and time to

In Oregon
The US Centers for Disease Control and Prevention is expected to shift its Covid-19 isolation guidance this spring to say that people no longer need to isolate once
The microclots may cause an inflammatory response, which causes exhaustion and fatigue, two of the most common long Covid symptoms
Second, treatment interruptions for those with SLE and other rheumatic diseases must be prevented, because lapses in therapy can result in disease flares and strain already stretched FDA is concerned that hydroxychloroquine and chloroquine are being used inappropriately to treat non-hospitalized patients for coronavirus disease (COVID-19) or to prevent that disease
With no antivirals or vaccines available for the treatment of COVID-19, the medical community is presently exploring repositioning of clinically approved drugs for COVID-19
Thirty years ago, when comparing in vitro and in vivo trials and experiments, Hellgren et al
Currently, at least ten clinical trials are testing chloroquine as an anti-COVID-19 therapy
Chloroquine — an approved malaria drug — is known in nanomedicine research for the investigation of nanoparticle uptake in cells, and may have potential for the treatment of COVID-19

Poor methods and reporting
For HCQ and chloroquine we found ample in vitro evidence of antiviral activity
Of several therapeutic drugs that have been suggested, chloroquine (CQ), an anti-malarial drug in the class of 4-aminoquinolones with anti-inflammatory, antiviral and anti-thrombolytic properties, and its derivative, hydroxychloroquine (HCQ) have been re-purposed and are being used widely for the treatment of COVID-19 [6,7]
As systems became overwhelmed, it was clear that effective, safe, accessible early outpatient treatments to prevent deterioration were needed
Chloroquine has been studied for the treatment and prevention of coronavirus disease 2019 (COVID-19)
When asked about the use of hydroxychloroquine to treat COVID-19, the FDA commissioner said, “The FDA’s responsibility to the American people is to ensure that products are safe and effective
