About Us

The Area 4 Pharmacotherapy Network (A4PN) is working to improve patient access to pharmacotherapy services in southern and eastern metropolitan Melbourne.

Pharmacotherapy is also commonly known as Opioid Replacement Therapy (ORT), Opioid Substitution Therapy (OST) and Medication Assisted Treatment of Opioid Dependence (MATOD). It is an effective evidence-based treatment for opioid dependence, involving the use of buprenorphine/naloxone,  buprenorphine or methadone.

Opioid dependence is a growing public health concern affecting a wide variety of people, including those who are prescribed opioids for pain and those who take illicit opioids.

Recovery and reduction in harms to the individual and wider community are some of the many benefits of pharmacotherapy.


A4PN supports health professionals across Victoria to prevent, identify and manage opioid dependence. 

Our services:

  • Direct access to local Addiction Medicine Specialists

  • Clinical advice and secondary consultations

  • Peer-to-peer mentoring for GPs and pharmacists

  • Accredited professional development opportunities, such as GP Peer Group Learning meetings

  • On-site and virtual education and support at your general practice or pharmacy

  • Whole-of-practice staff training and support for managing opioid dependence, including advice about MBS billing

See our Health Professionals page to find out more about how we can support you.

The Area 4 Pharmacotherapy Network (A4PN) is funded by the Department of Health and Human Services. South Eastern Melbourne PHN and Eastern Melbourne PHN are partners leading this initiative.
