Embodiment Construction

[0072] Specific embodiments of the disclosed medicated module and drug delivery system enable the administration of a fixed predetermined dose of a second medicament (secondary drug compound) and potentially variable ) dose of the first agent (primary drug compound). By setting the dose of the primary medicament by the user, the fixed dose of the second medicament can be automatically determined. This fixed dose of the second medicament may be a single dose. Furthermore, a second dose of a possibly variable dose of the first medicament may be administered via the same single dispense interface. In the context of this disclosure, the term "drug delivery interface" may be any type of outlet that allows two or more medicaments to exit the drug delivery system and be delivered to a patient. In a preferred embodiment, the single drug delivery interface comprises a hollow needle cannula.

[0073] In a preferred configuration, the drug delivery interface comprises: a needle cannul...

Abstract

A medicated module (100) is attachable to a drug delivery device (102). The medicated module (100) includes a housing (104) having a proximal end and a distal end, the proximal end has a connector (110) configured for attachment to a drug delivery device (102). The distal end contains a shuttle (112). A first needle (114) is fixed in the housing (104) and a second needle (116) is fixed in the shuttle (112). The medicated module (100) also includes a reservoir (118) in the housing (104) comprising a medicament (12). Further, the medicated module (100) includes a guard assembly (122) positioned in the housing (104) and configured to move in an axial direction during application to an injection site. Preferably, the medicated module (100) is locked out after at least two injections of the medicament (105) contained in the drug delivery device (102).

Description

technical field [0001] Particular embodiments of the present disclosure relate to medical devices and methods for delivering at least two drug agents from separate reservoirs utilizing a device having only a single dose setter and a single dispense interface. A single delivery program initiated by the user may deliver a non-user settable dose of the second drug formulation and a variably settable dose of the first drug formulation to the patient. The drug formulations may be contained in two or more multi-dose reservoirs, containers or packages, each containing separate (single drug compound) or premixed (co-formulated multiple drug compounds) drug formulations. Background technique [0002] Some disease states require treatment with one or more different agents. In order to deliver an optimal therapeutic dose, some pharmaceutical compounds need to be delivered in a specific relationship to each other. Here, combination therapy may be desirable but not achievable in a sing...
