Rx to OTC Switch-Market Analysis
Contents
Introduction
Over-the-counter (OTC) drugs are medicines that may be sold directly to a consumer without a prescription from a healthcare professional, and are commonly used to treat symptoms of common illnesses that may not require the direct supervision of a physician.
- For a medicine to be granted OTC status, it must have a wide safety margin and be effective, and must bear understandable labeling to ensure proper use
- More than 700 OTC products on the market today use ingredients or dosages, that were available only by prescription, less than 30 years ago
- Rx to OTC switch refers to the transfer of proven prescription drugs (Rx) to non-prescription, over-the-counter (OTC) status. Rx to OTC switch is a data-driven, scientifically rigorous, and highly regulated process that allows consumers to have OTC access to a growing range of medicines
There are two ways in which drugs are commonly switched as approved by FDA in US :
- The OTC Drug Review
- Began in 1972
- Ongoing assessment of the safety and effectiveness of all nonprescription drugs
- Panels of non-government experts review active ingredients in marketed OTC drug products to determine whether they can be classified as safe and effective
- About 40 former prescription-only drug ingredients have been switched by this process
- New drug application (NDA) process
- Manufacturers submit data to the FDA showing the drug is appropriate for self-administration.
- The submission includes studies showing that the product's labeling can be read, understood, and followed by the consumer without the guidance of a health care provider
- Some drugs are approved initially as OTC drugs, but most are first approved for prescription use and later switched to OTC
