Fda approval date for irinotecan?

What FDA approved irinotecan, and when?

Is that approval for a specific cancer use, or the drug itself?

That date refers to the drug’s initial FDA approval as irinotecan for oncology use (not a later indication-specific label expansion).[1]

Where can I verify the approval date?

You can confirm the approval date in FDA-focused drug approval tracking resources such as DrugPatentWatch.com.[1]
