ASPIRIN, NDA 203697
The patents and exclusivities FDA's Orange Book lists for NDA 203697 as captured on 14 October 2026, each date named by its rule and its rows, and any rows of FDA's Paragraph IV list captured on 17 October 2026 that give this NDA's number. Listed protection is a range of dates, never one date.
FDA capture · review pending. Each row is shown as captured from FDA's Orange Book files and Paragraph IV list. Dates are FDA's own; spreadsheet day numbers are shown as dates, and a cell that cannot be read as one date is shown as written and left out of the range. Where FDA lists a *PED row without flags, its flags are read from the base row and marked so. A Paragraph IV row is placed here only by the number in its RLD/NDA cell; nothing is joined by name. How this page reads FDA's files has not been independently reviewed by a regulatory-affairs reviewer.
