SMI, DPI, pMDI or Mesh Nebulizer: Drug Delivery Device Comparison FAQ
Answers for pharma partners comparing the four main handheld inhalation delivery platforms and what to consider when selecting a CDMO.
What are the four handheld inhalation drug delivery platforms?
The four main handheld platforms are the Soft Mist Inhaler (SMI), Dry Powder Inhaler (DPI), pressurized metered-dose inhaler (pMDI), and mesh nebulizer.
How does a Soft Mist Inhaler (SMI) deliver medication?
An SMI delivers medication as a slow, fine soft mist with high lung deposition. It is well suited to liquids and solutions that need deep-lung targeting and patient-friendly coordination.
What is a Dry Powder Inhaler (DPI)?
A DPI delivers a powder aerosol generated from the patient's inspiratory effort. It is breath-actuated and requires no propellant, making it good for stable powder formulations.
What is a pressurized metered-dose inhaler (pMDI)?
A pMDI is a propellant-driven metered-dose spray. It is compact and familiar, making it suitable for established formulations.
What is a mesh nebulizer?
A mesh nebulizer produces a fine mist via a vibrating mesh. It is suited to solutions and suspensions, larger volumes, and patient comfort.
How should a pharma partner select the right platform?
Key criteria include formulation compatibility (solution, suspension, or powder), lung targeting and particle size as reflected by the fine-particle fraction, usability and adherence, and the development and manufacturing maturity of the chosen partner.
Why consider a CDMO for inhalation device development?
A capable CDMO handles design, tooling, assembly, and regulatory documentation, reducing time to market. Regulatory confidence comes from quality systems such as FDA registration, CE marking under MDR, and ISO 13485.
Which platforms does DSB Medical develop and manufacture?
