What does the formulary under DIDFA list?

The formulary under the Drug Interchangeability and Dispensing Fee Act (DIDFA) lists all products that are defined as interchangeable. This means that the formulary includes medications that can be substituted for one another without compromising efficacy or safety. The inclusion of these interchangeable products is crucial because it provides pharmacists with the flexibility to dispense alternative medications while ensuring patients receive effective treatments.

Interchangeable drugs are typically those that have the same active ingredient, dosage form, strength, and route of administration, and they can be expected to have the same clinical effect and safety profile. This is significant in pharmacy practice as it allows for cost-effective dispensing, supporting both patient adherence and the efficient use of healthcare resources.

The other options do not accurately reflect the purpose of the formulary under DIDFA. For instance, banned drugs would not be part of a formulary aimed at promoting safe medication use, while drugs available only through hospitals or those requiring special approval have different regulatory considerations and would not be included in the interchangeable drugs listing.
