Overactive bladder: OTC oxybutynin transdermal patch for women

Area of Science:

• Urology
• Pharmacology
• Public Health

Background:

• Overactive bladder (OAB) is a prevalent condition affecting millions of adult women in the U.S.
• OAB significantly diminishes health-related quality of life for affected individuals.
• Many women with OAB do not seek medical treatment, despite its impact.

Purpose of the Study:

• To evaluate the efficacy and safety of an antimuscarinic agent for OAB.
• To assess the suitability of transitioning a prescription OAB medication to over-the-counter (OTC) availability.
• To inform the development of consumer-friendly drug labeling for self-treatment.

Main Methods:

• Review of existing efficacy and safety data for the prescription formulation of oxybutynin.
• Evaluation of consumer research studies to guide OTC product development.
• Assessment of the regulatory process for prescription-to-OTC drug switches.

Main Results:

• The prescription antimuscarinic medication demonstrated established efficacy and safety profiles.
• Consumer research provided insights into patient understanding and usability of OTC labeling.
• The transition to OTC availability was supported by prior clinical data.

Conclusions:

• An over-the-counter oxybutynin transdermal patch offers a new self-treatment option for women with OAB.
• The availability of OTC oxybutynin empowers females to manage OAB symptoms independently.
• The drug's efficacy and safety data support its use in a self-treatment context.
