Abstract:

Methods and devices for delivering variable amounts of a drug formulation directly from a drug delivery device without requiring point of use reconstitution as a separate mixing step are described herein. These methods and devices increase the convenience, speed and simplicity of administration of drug formulations. The devices mix two or more components in a constant mixing ratio effectively simultaneous to administration, and allow for variable doses while retaining the desired ratio of the components in each dose. The devices are particularly useful for administering drug formulations that are unstable at room temperature in liquid form. The methods described herein generally use conventional devices that have been modified to administer an unstable compound and provide acceptable storage stability. Typical devices include infusion sets, pump reservoirs, syringes, pens, vials and cartridges.
