Abstract
A medicated module for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device containing a primary medicament accepts a medicated module containing a single dose of a secondary medicament and where both medicaments are delivered through a hollow needle. The medicated module is initially in a locked state until attached to a drug delivery where a locking plate is moved to a triggering state. The medicated module does not require the user to manually engage a reservoir containing the secondary medicament. Instead, a biasing member automatically activates the reservoir when the needle guard is retracted when the module is in the triggering state. The needle guard prevents accidental needle sticks before and after an injection, and locks after dose delivery.
