Ability to achieve successful injection of drug or biologic depends on many factors including but not limited to needle diameter, drug viscosity, spring force, lubrication, plunger geometry and material properties. One additional challenge to be considered during verification of the drug delivery system is effect of back pressure from the patient (tissue). This talk will highlight various options and/or considerations for back pressure during feasibility and design verification testing. Concepts are broadly applicable to pen/auto injectors, on body delivery systems, pre-filled syringes and other delivery systems.
