Over-the-Counter (OTC) Applications
What is an Over-the-Counter Application? The Over-the-Counter Application is the documentation submitted to the FDA to gain approval to manufacture and market non-prescription or OTC medications. This documentation can either be an NDA or an ANDA based on the chosen marketing pathway.
Pathways for Marketing Approval of OTC drugs.
Direct-to-OTC pathway is used for drugs that have not previously received approval as a prescription drug and requires the submission of an NDA. These drugs are often already approved in foreign markets, and the FDA has post-marketing data available to them.
Prescription-to-OTC switch is used for drugs that have previously been granted NDA or ANDA approval. There are two types of prescription-to-nonprescription switches.
- Full switch requires the submission of an efficacy supplement by the sponsor. On approval, the drug will only be available as a non-prescription drug.
- Partial switch, during which the sponsor only switches some indications to non-prescription status. This requires the submission of a new NDA.
Additional requirements for OTC drug approvals
- Compliance with the OTC drug monograph system.
- Consumer studies demonstrating label comprehension, the ability of consumers to decide if the drug is appropriate for them, and prevention of use-related hazards.
- Efficacy and safety data, and post-marketing safety data for prescription-to-OTC switches.
