The New Drug Application (NDA) is the vehicle in the United
States through which drug sponsors formally propose that
the Food and Drug Administration (FDA) approve a new
pharmaceutical for sale and marketing.

– prove safety and efficacy
505(b)(2) Application
– Relies, at least in part, on published information or
– FDA’s past finding of safety and efficacy
– Examples: new dosage form, strength, route of
– administration, dosing regimen, indication
Abbreviated New Drug Application – 505(j)

– dosage form, strength, route
– Need prove only bioequivalence

new drug application (NDA), and it is a pathway to approval that

previously approved drug. Ideal candidates include:

route of administration
