Innovating solutions for accessible recovery

Frenelle PBC values equal access and putting patients first. We strive to improve the patient experience, and ensure critical medications are accessible to all.

Opioid Use Disorder

Opioid misuse affects 10 million individuals in the U.S., with 2.7 million formally diagnosed with Opioid Use Disorder (OUD) and 1.8 million treated with buprenorphine.


Many OUD patients relapse, supporting the need for an improved long-acting injectable treatment to enable patients to break this cycle.
