A chemical compound in viagra could help cure coronavirus patients: study

Since the coronavirus pandemic began, there have been many discoveries and findings that science has made. Although the vaccine against COVID-19 will take time to arrive, Some drugs that may be effective in helping patients are already known., as is the case of remdesivir, recently approved by the United States for use.

In this same sense, it has been discovered that one of the molecules that are part of viagra could be helpful in developing a drug against coronavirus. This is what a study still in progress at Massachusetts General Hospital (United States).

Nitric oxide is a short-acting gas that serves to widen the blood vessels in the lungs. When inhaled in high doses, patients increase their blood oxygen level, so that patients do not lose their respiratory capacity, as it happens in the most serious phases of COVID-19. For this reason, although it originally has a utility to treat erectile dysfunction, it can also be of great help in alleviating the main symptoms of the virus.

In the clinical trial a mask has been provided to patients, who for 30 minutes over 2 or 3 times a day receive this dose of nitric oxide. Meanwhile, another group of patients inhales a placebo so that the true effect of this gas on the body can be compared.

Preliminary trial results suggest that nitric oxide may even kill the virus.. In other words, it would not only alleviate the symptoms, but they would also make the coronavirus disappear from the body. This gas was already used to treat MERS and SARS in 2004 and 2005, and showed encouraging results.

Nitric oxide is often used to help some prematurely born babies breathe. They are also useful in adults suffering from respiratory hypertension, since it locally dilates the blood vessels near the lungs, without affecting those of the rest of the body.

This gas is not dangerous for humans. It is made up of oxygen and nitrogen, the most common compounds in the atmosphere.

For now, it is being used in 3 different lines of research: in seriously ill patients who need a respirator to continue living, in patients who begin to present severe lung problems, and finally in healthcare personnel who are exposed to the virus.

However, there is still time and the trial is further developed to verify that the preliminary results are so positive.
