Attempt to fast track some potential antiviral drugs from known drugs

In summary, researchers have evaluated 47 already known drugs for their potential to treat COVID-19 and have found promising leads. These drugs are now being tested on patients in clinical trials. Interestingly, it was found that dextromethorphan, commonly used in cough syrup, may actually encourage the virus in lab tests. This highlights the importance of carefully evaluating medications and not just relying on all-in-one treatments. Simple natural remedies like honey and drinking plenty of fluids may be more effective in soothing symptoms.

This is not anything we can use today, but is an intelligent way to find something to abate Covid 19, i.e., an anti-viral drug. Ones that we already know and use for another purpose. Please read the popular article, it is meant for non-biologists.

1. Evaluate all of the already known drugs, ones used and accepted for another purpose. All of these drugs have had extensive testing and are actively used today.
2. Take the few that have potential, 47 drugs, test them on green monkey cells in the lab.
3. Perform clinical trials on patients with the best one(s) from step 2.

Several have been found and have been, or are being, moved into step 3.

An interesting side note: dextromethorphan (cough syrup med) seems to encourage the virus in lab tests. They are going to evaluate whether this is a real effect before notifying clinicians to stop patients from taking the drug for a cough. Ironically one of the symptoms of Covid 19.

Sort of an "un-medicine" - one that helps the pathogen instead of the patient. Just what do not need right now.

All of this is still up in the air. We have to wait until step 3 is complete, then we can see what further steps, if any, are needed.

The real takeaway is that when you get the world's bio-scientists geared up and all pulling toward the same goal, an amazing amount of innovative research can happen.

Looks to be pretty common. It's in both of the cough medicines we had in our cabinet. Guess we'll set these aside until we get vaccinated next month... :wink:

I don't think the stuff about cough medicines is really new. There are two main types the ones that suppress coughing, dextromethorphan being the most commonly used these days and then these are expectorants like guaifenesin.
If people have a dry irritating cough a suppressant will help, but of course coughing is one of our natural defences to try and remove irritants. Expectorants are used to help loosen thick mucus and make it easier to cough up, there are loads of these. A lot of other medicines add all sorts of other drugs like antihistamines and decongestants.
In real terms none of these things are considered a treatment for anything, they are primarily for comfort, it also makes sense that drugs that suppress some of our natural defences like coughing, might be counter productive. This is one of those areas in which some simple natural products might be the best to consider, honey containing drinks can help sooth irritated throats. I say drinks because plenty of fluids is probably the best way to loosen mucus.
The all in one treatments with all sorts of drugs are probably best avoided.

1. What is the purpose of fast tracking antiviral drugs from known drugs?

The purpose of fast tracking antiviral drugs from known drugs is to expedite the process of finding effective treatments for viral infections. By repurposing existing drugs, scientists can bypass the lengthy process of developing new drugs from scratch and potentially save lives in the face of a viral outbreak.

2. How do scientists determine which known drugs to use for fast tracking?

Scientists use a variety of methods to determine which known drugs may be effective against a particular virus. This can include screening existing drugs for potential antiviral activity, studying the mechanisms of action of different drugs, and analyzing the chemical structures of known drugs to identify potential candidates.

3. What are the potential risks of fast tracking antiviral drugs from known drugs?

One potential risk is that the repurposed drug may not be as effective against the virus as originally hoped. Additionally, there may be unknown side effects or interactions with other medications that could arise from using a drug for a different purpose. It is important for scientists to thoroughly test and monitor these drugs before making them available to the public.

4. How long does the fast tracking process take?

The fast tracking process can vary in length depending on the specific drug being repurposed and the urgency of the viral outbreak. It typically involves several stages of testing and clinical trials, which can take anywhere from a few months to a few years. However, in emergency situations, the process may be expedited to make the drug available as quickly as possible.

5. Are there any successful examples of fast tracking antiviral drugs from known drugs?

Yes, there have been several successful examples of fast tracking antiviral drugs from known drugs. For example, the drug remdesivir was originally developed for Ebola but is now being used to treat COVID-19. Another example is the drug oseltamivir, which was originally developed for influenza but has also been found to be effective against other viruses such as SARS and MERS.
