What does FDA approved mean?

What does FDA approved mean? Yeah, I mean, Food and Drug Administration in the United States approves the drugs for use in patients and most of the times, you know, they want to see the drug is safe, as we discussed in phase one studies and also in phase two studies showing effectiveness and also in phase three studies to show that it is effective compared to already established standard of care and it is safe to be given. So once the drug shows the safety and effectiveness, then only it will be approved for that indication by the FDA.
