A third class of drugs: an overview.

Area of Science:

• Pharmaceutical policy
• Drug regulation
• Public health

Background:

• Current US drug distribution has two classes: prescription-only and unrestricted over-the-counter (OTC).
• The existing prescription-to-OTC switch process offers a potential pathway for new drug classifications.

Purpose of the Study:

• To discuss the feasibility of establishing a third drug classification.
• To explore a model where drugs are available without a prescription but dispensed exclusively by pharmacists.

Main Methods:

• Literature review and policy analysis of current drug distribution models.
• Examination of the prescription-to-OTC switch process and its implications.
• Discussion of public policy justifications, including healthcare quality and economic impact.

Main Results:

• A third drug class, dispensed by pharmacists without a prescription, is a possibility.
• Significant obstacles hinder the establishment of this new drug class.
• Public policy justification requires demonstrating improved healthcare quality and manageable economic consequences.

Conclusions:

• Establishing a third drug class requires careful consideration of regulatory, economic, and public health factors.
• The success of such a class hinges on clear benefits to public health and economic viability.
