Early in the COVID-19 pandemic, there was a desperate need for a therapy against the scourge which was decimating health care systems worldwide
In the prevention and treatment of Coronavirus disease 2019 (COVID-19) in the United States, 74% trust their health care providers
The original report of hydroxychloroquine as a treatment for Covid-19 described 26 patients who had been treated in an open-label, single-group study that involved contemporaneous, but Taking hydroxychloroquine to prevent COVID-19 may increase the risk of diarrhoea, nausea, abdominal pain, drowsiness and headache

The treatment group received oral HCQ 400 mg/d (200 mg twice daily) from day 1 to 5
27%, of the receipt of immunosuppression it was 39
In this randomized, double-blind, placebo-controlled trial, we investigated the efficacy of hydroxychloroquine as Covid-19 postexposure prophylaxis
Thanks to modern medicine, the stifling, deadly cloud of the worst pandemic in more than a century was lifting
We investigated the effect of HCQ and CQ in hospitalized patients on the non-ICU COVID-ward
7%) patients reported QT prolongation
The drugs have some in vitro activity against several viruses, Rapid reporting and dissemination of results and its consequences regarding the use of hydroxychloroquine for COVID-19

It has mainly been used in Latin America as compassionate treatment with no evidence supporting its efficacy in COVID-19; some health ministries have even modified their treatment policies Background: In France, the combination hydroxychloroquine (HCQ) and azithromycin (AZ) is used in the treatment of COVID-19
Mechanism of action of hydroxychloroquine

In the early phase chloroquine phosphate and hydroxychloroquine sulphate have been used to fight this illness on the basis of handful observational and small randomized Fig
17 According to the COVID-19 EMA pandemic task force, both drugs have been shown to cause heart rhythm problems due to Based on these early reports, hydroxychloroquine alone and in combination with azithromycin was incorporated into our institutional clinical guidelines for the treatment of hospitalized patients with COVID-19
With the onset of the COVID pandemic, India has been facing several issues, such as shortage of diagnostic tools, medical equipment, and related medical supplies
The outbreak of coronavirus disease-19 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly evolved into a global pandemic
Also, the rate of serious adverse effects was similar between both Groups 1
First, hydroxychloroquine might be effective in early treatment, since the absence of evidence is not evidence of absence
Thus, the potential benefit of hydroxychloroquine in the Introduction
In fact, these two drugs have been used for decades for the therapy and control of malaria and Physicians prescribing drugs off-label to Covid-19 outpatients in Brazil have been backed and encouraged by a decision from the Brazilian Federal Board of Medicine issued in April 2020 that authorised, in the name of "physician's autonomy," the prescription of hydroxychloroquine to early/mild Covid-19 cases, and by a protocol from the The FDA revoked the emergency use authorization (EUA) for hydroxychloroquine for the treatment of COVID-19 on June 15, 2020, after results from several clinical trials failed to show that HCQ We aimed to determine whether early treatment with hydroxychloroquine (HCQ) would be efficacious for outpatients with COVID-19
This randomised, double-blinded, placebo controlled clinical trial evaluated the efficacy of hydroxychloroquine plus azithromycin (HCQ/AZT) in reducing viral loads in patients with early and mild SARS-CoV-2 infection
10-12 However, lack of evidence on efficacy and safety led multiple Norwegian coronavirus disease 2019 (NO COVID-19) pragmatic open label study to assess early use of hydroxychloroquine sulfate in moderately severe hospitalised patients with coronavirus disease 2019: A structured summary of a study protocol for a randomised controlled trial
Currently, there is insufficient evidence about the efficacy and safety of hydroxychloroquine in COVID-19
Effect of Early Treatment With Hydroxychloroquine or Lopinavir and Ritonavir on Risk of Hospitalization Among Patients With COVID-19: The TOGETHER Randomized Clinical Trial | Infectious
1: Hydroxychloroquine (HCQ) shows several potential effects against
Hydroxychloroquine is an anti-malaria drug that was prescribed off-label to treat COVID
In this randomized, double-blind, placebo-controlled trial, we investigated the efficacy of hydroxychloroquine as Covid-19 postexposure prophylaxis
Hydroxychloroquine (HCQ) has no clinical benefit in treating COVID‐19 in hospitalized patients, with moderate‐ to high‐certainty evidence from several randomized trials, and a probable increase in adverse events associated with its use
It was quickly adopted in China, Europe, and the USA
Conclusions
HCQ is
It was developed more for its use in rheumatological conditions []
In the early phase chloroquine phosphate and hydroxychloroquine sulphate have been used to fight this illness on the basis of handful observational and small randomized Fig
Initial interest in the use of HCQ was triggered by a small nonrandomized study that has since received heavy criticism The agency stressed that patients and healthcare professionals only use chloroquine and hydroxychloroquine for their authorized use or as part of clinical trials or national emergency use programs for the treatment of COVID-19
2 claimed that “ultimately, Hydroxychloroquine did not have clinical benefit,”2 and that, therefore, “we can finally close the curtains on Hydroxychloroquine for COVID-19
With the onset of the COVID pandemic, India has been facing several issues, such as shortage of diagnostic tools, medical equipment, and related medical supplies
The global push for the use of hydroxychloroquine (HCQ) and chloroquine (CQ) against COVID-19 has resulted in an ongoing discussion about the effectivity and toxicity of these drugs
One major challenge in the battle against this deadly disease is to find effective therapy
