Dual chamber injection devices can be classified as either dual chamber syringes or dual chamber pen injectors. The Pen injector segment can be further divided into single-use dual chamber pen injectors and reusable dual chamber pen injectors. The latter relies on the use of a replaceable dual chamber cartridge that is inserted into the pen injector prior to use. While the use of dual chamber devices represents a cost premium for drug marketers relative to competing reconstitution methods such as vial adaptors, it also provides an opportunity for branding.
Because of stability and shelf life factors, therapeutic proteins must either be stored under special conditions or formulated to retain their efficacy from the time of manufacture until they are dispensed. Liquid protein drugs require refrigeration until dispensed - a distribution strategy referred to as the 'Cold Chain'. Alternatively, proteins can be formulated as powders. These lyophilized proteins must be reconstituted prior to injection.
The correlation between chronic conditions and the benefits of patient self-administration continues to influence therapeutic product decisions, managed care initiatives and regulatory actions. Drug injection device designs are increasingly being based on the results of human engineering inputs and patient preference research. Branding and packaging choices are more frequently being driven by data sources historically employed by consumer product marketers. For drug developers and device suppliers, the implications of these trends are influencing product development methodology and changing supply chain relationships. Decisions regarding as-supplied packaging that were once considered boilerplate have moved to the early stages of the development process.
