SINGLE SHOT NASAL unidose systems with proven performance

Aptar Pharma's UDS was designed to enable the systemic delivery of drugs without the need for injection or administration by a healthcare professional.

Available for both liquid and powder formulations, the UDS devices are robust, primeless, easy-to-use systems with one handed actuation, 360° functionality and precise nasal drug delivery.
Approved with multiple drug products by the FDA, with over 100 million units sold worldwide, Aptar Pharma's UDS liquid and powder devices are used by thousands of people every day in a range of scenarios from migraine medication through to breakthrough pain in end-of-life situations.

UDS are applicable for therapies where a small and very precise amount of active drug formulation is required in a single nasal shot. Some of these therapies delivered intra-nasally require high deposition in targeted areas of the nasal cavity. The nose-to-brain pathway which may allow therapeutic compounds to enter the CNS requires the targeting of the upper part of the nasal cavity or “the olfactory region”.

Our range of UDS, and in particular the UDS powder, is designed to address the nose-to-brain pathway. Dry powder formulations bring additional benefits, such as lack of preservatives, administration of larger doses of drugs and the improved stability of the formulation.
