Nasal drug delivery depends on many factors, including the conditions of use by the patient, the drug formulation, and the spray pump and aerosol characteristics. In recent years, the types of drug administered via the nasal route have expanded from locally acting drugs, such as those for allergic rhinitis, to delicate molecules for systemic activity, such as vaccines, proteins and peptides, which can be difficult to administer noninvasively. While the nasal cavity provides a delivery pathway for these large molecules, the rate of mucociliary clearance in the nasal cavity may hinder the extent of absorption. Therefore, formulators must develop mechanisms that improve absorption for high molecular weight compounds.

Respirable drug delivery is becoming increasingly popular because it provides a non-invasive route with rapid drug uptake, not only for the treatment of respiratory complaints, but also for the systemic delivery of substances that cannot be delivered orally.
