Rx to OTC Switches Represent Huge Market Potential

By Charles Jaap, MBA, RAC 

Rx to over-the-counter (OTC) switches and the related repositioning of pharmaceutical products from prescription (Rx) dispensing to the retail drug space represent huge market potential.

A strong domestic OTC market

The US market for OTCs more than doubled between 2007 and 2013, growing from $16 billion to $33 billion. [1]

By the beginning of 2014, 240 million Americans were using OTC medicines. [2] When a product moves from behind the pharmacist’s counter to the retail shelf, it can deliver significant increases in revenue.

For example, when nicotine replacement therapies switched to OTC, sales nearly doubled in the first year. [3] [4] Click here to view additional examples of successful Rx-to-OTC switches. [5]

The customer base also tends to be brand loyal as it has been reported that 60 million consumers would not seek alternatives if their OTC medicines were unavailable. [6]

Growing international sales for OTC medicines

Compounding the potential of the US marketplace, global sales for nonprescription drugs are expected to exceed $70 billion by 2015. [7]

Favoring this trend, the European Union, China and other countries have broadened their policies for nonprescription use of drug products that were once available only by prescription. [8]

NSURE expanding Rx to OTC switches

Launched in 2012, FDA’s Nonprescription Drug Safe Use Regulatory Expansion (NSURE) initiative is reviewing a number of disorders and prescription (Rx) drug classes that hold promise for conversion to nonprescription (also known as OTC) status.

Potential therapeutic classes that may become more open as a result include migraine treatments, statins, erectile dysfunction medications, sleep aids and drugs to treat other chronic conditions.

NSURE initially comprised representatives from the FDA, healthcare staff from the Brookings Institute and various Rx to OTC experts. [9]

A public hearing was held on 22-23 March 2012 entitled ‘Using Innovative Technologies and Other Conditions of Safe Use to Expand Which Drug Products Can Be Considered Nonprescription’. [10] [11]

By leveraging technologies and conditions of safe use, NSURE seeks to expand the Rx to OTC switch paradigm, increasing consumer access to necessary medications through nonprescription drug products.

Through the public hearing, the FDA requested comments on the proposed new paradigm, including its potential benefits and costs, which might contribute to making more of the current Rx therapies available to patients, without a prescription. [12] [13]

Rx to OTC switches are become increasingly more consistent with objectives of the Affordable Care Act, as well as regulatory agencies worldwide, including the FDA.

Not a third class of drug products

The NSURE initiative does not seek to create a third class of drug product or necessarily add to the ranks of ‘behind-the-counter’ drugs.

The expectation is that NSURE will encourage creation of rapid diagnostic testing, monitoring technologies and the integration of healthcare professionals into existing regulatory pathways to help expand the pool for OTC drug products available to the consumer. [14]

Better access for better outcomes

Several factors contribute to the under-treatment of common diseases such as insurance, medication costs, and inadequate access to care. [15]

Many Americans lack regular access to basic pharmacotherapy, a constraint that is believed to contribute to under-treatment of many common disorders. [16]

Of particular concern to the NSURE panel was the under-treatment of common chronic diseases that have substantial impact on public health in terms of controllable costs and preventable suffering. [17]

Research suggests that 20%-30% of prescriptions are never dispensed and fully half of common chronic disease therapies are not taken as prescribed.

Nearly 67 million adults have hypertension, yet more than half do not have it under control.

More than 15% of sufferers simply do not treat the disorder. Similar concerns exist for conditions such as diabetes, COPD and others. [18] [19]

Affordable access to medication plays a significant role in equipping consumers to manage their healthcare. The FDA believes greater availability of safe and effective OTC medications is a worthwhile endeavor. [20]

Safe consumer use remains pivotal to Rx to OTC switches

While the outlook for Rx to OTC switches becomes increasingly favorable, do not look for change in the key factors related to the conversion of medications from prescription-only to OTC status.

Safe and effective use will continue to be critical elements that must be demonstrated in the NDA:

  • The patient must be able to adequately self-diagnose his or her medical condition.
  • The medical condition must be successfully self-treated with the nonprescription product.
  • Self-treatment with the nonprescription medication must be safe and effective under the conditions of actual use by the consumer. [21]

Expect 505(b)(2) changes

What is expected to change is the mix of innovative new components that may be included in 505(b)(2) NDAs for Rx to OTC switches.

For example, submissions may conceivably include demonstration of effective pharmacist/patient interfaces and/or proof of patient proper and compliant use of new monitoring technologies.

Rx to OTC consultants helps streamline the switch process

The FDA expressed a desire to increase access to safe and effective nonprescription medications.

The opportunities to bring medications, technology, healthcare professionals, and patients together are wide open.

The key to success with an Rx to OTC conversion begins at project conception and includes start-to-finish strategic drug development planning.

A strategic pharmaceutical consultant such as PDG, experienced with full and partial Rx to OTC conversions and nonprescription NDAs can help streamline the process. The path to the next OTC blockbuster could be as close as your next meeting with PDG and the FDA.
