What is a Patient Access Scheme (PAS)?
A patient access scheme (PAS) is a confidential discount agreement between a pharmaceutical manufacturer and a payer. The term is similar to drug rebates in the US, but PAS is more commonly used in areas with single payer systems and especially the UK.

The details of a PAS are come to following negotiation between the manufacturer and payer and may involve set ceilings as determined by local HTA bodies (such as NICE in the UK).
