Problems solved by technology

This problem means that pre-mixed formulations of multiple active agents may not be suitable, as these premixed formulations may have a fixed ratio of active ingredients that cannot be changed by the health care provider or user
[0006] There is also the problem of requiring multiple drug mixture treatments, as many users cannot handle delivery systems that must use more than one drug, or make the necessary precise calculations of the required dose combinations

Embodiment Construction

[0043] According to specific embodiments of the disclosed drug delivery device, a non-user settable or fixed or predetermined dose of a second drug (adjuvant mixture) and a variable dose of a first drug (primary drug mixture) are delivered via a single output or Medication dispensing interface dispense. The dose of the primary drug set by the user automatically determines the fixed dose of the second drug. In a preferred embodiment, the drug dispense interface is a needle cannula (hollow needle). figure 1 One possible embodiment of the invention is shown, in which a multi-use injection device 10 (housing not shown) has two reservoirs arranged side by side, one containing a first medicament 1 and the other containing a second medicament 2 . As an example, the first drug 1 is insulin. The second drug 2 may be GLP1. Preferably, the reservoirs contain multiple doses of each drug. Each reservoir is preferably self-contained and provided as a sealed and sterile cartridge. These...

Abstract

A injection system for co-delivery of two medicaments (1, 2) having a drug delivery device (10) containing a primary reservoir containing a first medicament (1) and that has a secondary reservoir containing a second medicament (2) where the drug delivery device (10) has only one dose setter (12) for the primary reservoir and that automatically determines the dose of the second medicament (2). Both medicaments (1, 2) are delivered through a single dispense interface.

Description

technical field [0001] According to specific embodiments, the present application relates to medical devices and methods for delivering at least two medicaments from separate reservoirs using a device having only a single dose setter and a single dispense interface. In particular embodiments, a single delivery program initiated by the user results in a non-user-settable dose of the second medicament and a user-variable set dose of the first medicament to be delivered to the patient. The medicaments are contained in two or more dosage reservoirs, containers or packages, each of which contains separate (single drug compound) or pre-mixed (co-formulated multi-drug mixture) medicaments. The present invention is particularly beneficial as the therapeutic response can be optimized for a specific target patient group by controlling and defining the treatment regimen. Background technique [0002] Certain disease states require treatment with one or more different drugs. Certain d...
