2. Formulary Management:

Formulary Development: GPOs collaborate with PBMs to develop and manage formularies that optimize medication access, affordability, and clinical outcomes for member organizations.

Therapeutic Interchange Programs: GPOs may implement therapeutic interchange programs that encourage the use of cost-effective or preferred medications within member organizations’ formularies, promoting cost savings and medication safety.

3. Clinical Support and Education:

Clinical Guidance: GPOs provide member organizations with clinical support, evidence-based guidelines, and educational resources to promote rational medication use, adherence to formulary protocols, and adherence to best practices in pharmacy management.

5. Advocacy and Representation:

Policy Advocacy: GPOs advocate for policy changes, regulatory reforms, and industry initiatives that promote transparency, accountability, and fairness in pharmacy benefit management practices.

Stakeholder Engagement: GPOs engage with PBMs, pharmaceutical manufacturers, regulatory agencies, and other stakeholders to address emerging challenges, promote innovation, and advance shared goals related to medication access, affordability, and patient care.
