You're missing the point that patients receiving this treatment are considered in a terminal condition and are likely on life-support (that is the only situation you could give an unapproved drug to a patient).
This is not an unapproved drug, just an off-label use. From wikipedia:
> Chloroquine was discovered in 1934 by Hans Andersag.[3][4] It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system.[5]
Where did you see that this is for terminal conditions? Raoult suggested even patients with mild symptoms be treated with those molecules to reduce the contagion.
