Why 503B of the FD&C Act matters

As a long-time advocate for clearer FDA authority and stronger oversight, PharMEDium has been voluntarily registered with the FDA since its inception – more than two decades before the passage of the Drug Quality and Security Act (DQSA).

Advancing the science behind what we do.
