又一个坏消息,羟氯喹估计也没戏了。
FDA warns against using hydroxychloroquine for coronavirus outside of hospitals
Clinical trials can continue, but the drug's heart risks are too great to be used outside of controlled settings.

The Food and Drug Administration on Friday cautioned against prescribing hydroxychloroquine to COVID-19 patients outside of hospital settings or clinical trials. The drug, an antimalarial, was repeatedly touted by President Donald Trump as a possible treatment for the coronavirus.
"The FDA is aware of reports of serious heart rhythm problems in patients with COVID-19 treated with hydroxychloroquine or chloroquine, often in combination with azithromycin," the
FDA wrote on its website.

"We are also aware of increased use of these medicines through outpatient prescriptions. Therefore, we would like to remind health care professionals and patients of the known risks associated with both hydroxychloroquine and chloroquine," the FDA said.
The agency said hydroxychloroquine can still be used in hospital settings or in clinical trials, but it was not immediately clear whether some planned trials would be stopped.
Cardiologists have been sounding the alarm about hydroxychloroquine's heart risks for weeks, saying the drug could be deadly in a small number of patients who are susceptible to heart conditions.
