WHO: Dexamethasone is the only effective drug

The director general of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, said that dexamethasone is currently the only drug that has been shown to be effective against the severe form of COVID-19.

Dexamethasone is a corticosteroid that with the arrival of COVID-19 was put into practice to attack the disease, showing its initial results in a clinical trial carried out in the United Kingdom that indicated that it can save the lives of patients with the virus in critical condition .

Treatment reduces mortality by approximately one third among patients requiring ventilation and by approximately one fifth among those requiring only oxygen therapy.

Test. Adhanom recalled that six months ago the WHO launched the Solidarity Trial, the world's largest randomized controlled test of the therapeutics of COVID-19 that involves almost 13.000 patients in 500 hospitals in 30 countries, to evaluate the effectiveness of four drugs for the treatment of this disease.

He stressed that in June the agency announced the suspension of the hydroxychloroquine group and in July it did the same with the combination of lopinavir and ritonavir. Now, interim results have also shown that remdesivir and interferon have little effect in preventing death from COVID-19.
