Question 21

A new NDC number must be assigned after a substantial change in a medication's dosage form.

A new National Drug Code (NDC) number is required when there is a substantial change in the dosage form of a medication, as this change can significantly affect the way the drug is manufactured, prescribed, and administered.

A) indication

While changes in a medication's indication can be significant, they do not necessitate a new NDC number according to federal law. The indication pertains to the disease or condition the drug is intended to treat, and such changes are not categorized as substantial alterations in the drug's formulation or delivery.

B) inactive ingredients

Changes in inactive ingredients may be important for the formulation of a medication, but they do not automatically require a new NDC number unless they affect the drug's safety or effectiveness. Federal law typically recognizes that alterations in inactive components alone do not constitute a substantial change warranting a new NDC.

C) expiration date

The expiration date of a medication is related to its stability and shelf life, but it does not represent a change in the medication's formulation or delivery method. Therefore, an updated expiration date does not trigger the need for a new NDC number.

D) dosage form

A change in the dosage form of a medication, such as switching from a tablet to a liquid or changing the delivery mechanism, does require a new NDC number. This is because the dosage form directly impacts the drug's administration and effects, making it a substantial change necessitating reclassification under federal regulations.

Conclusion

The requirement for a new NDC number is specifically tied to substantial changes in a medication's dosage form, which can significantly influence patient outcomes and drug usage. Other options, such as changes in indication, inactive ingredients, or expiration dates, do not meet the criteria for requiring a new NDC, thus reinforcing the importance of dosage form as the correct answer.
