An experimental Ebola drug was deemed ethical by the United Nations on Tuesday, and will be sent to Liberia to treat two sick doctors.

The U.N. debated the ethics of Zmapp this week because the drug was never tested on humans.

As long as users of Zmapp have "informed consent, freedom of choice, confidentiality, respect for the person, preservation of dignity and involvement of the community," they can use the drug, according to the U.N.

So far, two Americans and one Spanish person have used this drug. All patients were sent to their home countries before the treatment.

As of Monday night, 1,013 people have died due to Ebola.

"There's no reason to try this medicine on sick white people and to ignore blacks," Marcel Guilavogui, a pharmacist in Conakry, Guinea told The Associated Press. "We understand that it's a drug that's being tested for the first time and could have negative side effects. But we have to try it in blacks too."

The U.S. government said it had put Liberian officials in touch with Mapp Biochemical Inc., which made the drug, reported AP.

Liberia issued a statement saying it is also receiving an experimental treatment from the World Health Organization. It's unclear whether the drug they referred to is Zmapp, because there are other experimental drugs in development.
