Plaquenil and chloroquine tab

Why President Trump is at odds with his medical experts over using malaria drugs against Covid-19

And a small and preliminary clinical trial of hydroxychloroquine in France circulated widely and stirred excitement on social media including from the president — though its findings were hardly definitive about whether the drug would benefit coronavirus patients. Doctors can already prescribe them off-label. I feel good about it. Just a feeling.

Several other small studies of other antiviral drugs have also shown glimmers of hope. So what should doctors do?

A 100% COVID-19 cure? No, chloroquine effectiveness only anecdotal

Hydroxychloroquine: learn about side effects, dosage, special precautions, and more on MedlinePlus. Medscape - Indication-specific dosing for Plaquenil (hydroxychloroquine sulfate), Dosage Forms & Strengths. tablet. mg. Malaria. Prophylaxis. Indicated for prophylaxis of malaria in geographic areas where chloroquine resistance is not.

How likely is it that the possible benefits shown in a small study will turn out to be a mirage? One way of understanding this is to look at what happens with medicines in clinical trials. Experimental drugs are usually studied in three stages of progressively larger studies. The first, called Phase 1 trials, are small studies used to get an early read on efficacy and rule out obvious safety issues. The study referenced by Trump , and other studies done so far of potential treatments for Covid, are small and hastily designed even by the standards of Phase 1 studies.

So how often do infectious-disease drugs that enter Phase 2 studies reach the market? An analysis by the Biotechnology Industry Organization says they worked out only That means that three-quarters of the time, medicines against infectious disease that looked promising in small studies either were ineffective or had side effects that made them unusable. It goes to one of the big truths about how doctors, eager to see a new drug succeed, can subconsciously lie to themselves with clinical studies: To be trustworthy, these studies often need to be randomized.

The use of randomization as the standard way to design a medical study goes back to another deadly infectious disease: tuberculosis. In the early part of the 20th century, it was a scourge, and many doctors turned to gold-based treatments, to try and control it.

What is Hydroxychloroquine?

They turned out to be toxic and ineffective. That study, published in the British Medical Journal in , became the basis for most modern medical research. The study Trump and others have touted was anything but randomized. Instead, Covid patients were treated with either hydroxychloroquine or the combination of hydroxychloroquine and azithromycin, an antibiotic also known as Zithromax, at a hospital in Marseille, France. But for doctors on the front lines, particularly in New York City, where hospitals are becoming overwhelmed and where there are many patients on ventilators, the drugs could be an immediate option.

Perhaps as a result, there are shortages cropping up for patients with lupus and other diseases who need the drug. The University of California, San Francisco , and the University of Washington both recommend hydroxycholoroquine for very sick Covid patients.

Chloroquine or Plaquenil: What is it and can it really treat coronavirus?

The qualms about the French study extend to two other studies of antiviral drugs as potential Covid treatments. A study of 80 patients given the Japanese flu drug favipriavir, which is not approved in the U. A small randomized trial of HIV medicines, published in the New England Journal of Medicine, found no overall benefit, but hints that it helped some subgroups of coronavirus patients. For drug development, getting results so soon is blindingly fast.

For doctors on the ground and patients who are struggling to breathe, it is agonizingly slow.

Republish this article. Efficacy is not assessed until Phases II and III, where the drug is tested, in double-blind fashion, against a placebo control.

What the heck does Trump know about medicine? He sounds like an idiot.

The Pres is right on this one, we need to follow the French protocol and give very sick people a chance to live. I agree with Thomas laValley. Are they cheerleading for the FDA?

  1. Indications and dose!
  2. The science behind chloroquine.
  3. Why is this medication prescribed??

Because these are given in tablet form and there is a five day regimen hopefully wider usage on positive tested patients providing informed consent will build the case for this regimen as well as remdesivir. If a person is drowning front of you, would any of you take the time to determine if the flotation device you are about to throw is US Coast Guard approved?

The hospitals should already have this information. James DiNicolantonio , a cardiovascular research scientist and doctor of pharmacy based in Kansas City, Missouri.

Regarding the danger of metastases, the analyses had been first run within the general population. The changes are most often permanent, but in some cases, vision has improved. Retrieved 18 March Int J Antimicrob Agents. Which make sense, since these compounds accumulate in the lysosomes, due to their high logP and basicity. Patients can save significantly on their prescriptions medicine when buying them from a licensed pharmacy in the United Kingdom and different international locations such as Canada, Australia, and New Zealand. However, aged sufferers are more likely to have age-associated kidney problems, which may require caution and an adjustment in the dose for patients receiving this medicine.

But DiNicolantonio and other physicians warn that the drug cocktail could be lethal for patients with underlying heart conditions. And, in the hands of children, even small doses may be lethal. Furthermore, the mad rush to get hold of these drugs is causing significant shortages among pharmacies and drug manufacturers , which may put lives at risk, particularly in those who rely on these drugs to treat life-threatening conditions, such as lupus.
