In this episode, Gwen and Petra take on a Vital Health Podcast best-of about generic drug shortages and supply chain risk. They unpack the healthcare terms at the center of the discussion – generics, biologics, biosimilars, APIs, and PBMs – and explain how pricing pressure, manufacturing concentration, and reimbursement dynamics can affect whether medicines actually reach patients. It is a plain-English look at why drug shortages are not just a pharmacy problem, and why keeping medicines affordable also means keeping a strong supply chain.
