Is PDUFA the same as FDA approval?

Excuse me, I've been doing some research on the drug development process and came across the term PDUFA. Could you please clarify for me if PDUFA is synonymous with FDA approval? I understand that the FDA oversees the approval of drugs in the US, but I'm a bit confused about the role PDUFA plays in this process. Could you elaborate on the difference, if any, and how PDUFA fits into the overall framework of FDA drug approvals? Thank you in advance for your clarification.
