What was studied?
Model insulin compacts combined two permeation enhancers with excipients and underwent compression, release and accelerated-storage testing.
What did the researchers report?
The enhancers differed in manufacturing properties. Blended formulations showed different degradation and aggregation behavior from raw insulin under the tested storage conditions.
What are the limits?
Accelerated model testing does not determine a universal shelf life. Excipient effects are formulation-specific, and these results do not provide a preparation recipe for catalog products.
