PFSITM Soft Mist Inhaler

The Pre-Filled Syringe Soft Mist Inhaler (PFSI™) is a ready-to-use, patient-friendly platform that combines high-performance drug delivery with everyday convenience. Compact and pocket-sized, it ensures efficient delivery deep into the lungs, giving patients the therapy they need, when they need it.

Device Overview
High-Performance Lung Delivery, Made Simple

The Pre-Filled Syringe Soft Mist Inhaler is a ready-to-use, patient-friendly inhalation platform that combines high-performance drug delivery with everyday convenience.

Compact and pocket-sized, it delivers over 60% of the dose deep into the lungs, giving patients the therapy they need, when they need it. Designed for both biologics and small molecules, the PFSI™️ protects sensitive formulations with our proprietary Rayleigh spray nozzle technology and high-quality glass syringe primary packaging.

The device generates a gentle, propellant-free aerosol cloud to ensures precise and efficient drug delivery to the lungs. Available in both reusable and disposable configurations, the PFSI™ adapts to treatment schedules ranging from single-day course to month-long therapy.

Its ergonomic base unit and precision cartridge system enable multiple uses while maintaining sterile integrity at every replacement. Made with recyclable materials, the PFSI™ enhances patient convenience while reducing waste and environmental impact.

Why choose PFSI™?
  • Metered, propellant-free, multi-dose inhaler
  • Glass container closure system to protect your formulation
  • Reloadable for multiple use. Recyclable at the end of life
  • Sterile integrity with every cartridge change
  • Built-in flow guidance to support consistent inhalation
  • High-efficient drug delivery for optimal lung deposition and reduced waste
  • Low shear stress spray technology for sensitive biologic molecules
  • Scalable technology utilising existing manufacturing infrastructure
Device Tailoring
Your Therapy, Your Device

The flexible design of the PFSI™ adapts to the unique needs of each therapy, ensuring formulation compatibility and optimal patient outcomes.

Spray and aerosol profiles can be optimised for specific formulations, while customisable metered dosing enables precise, targeted treatment. Sensitive molecules are safeguarded through gentle, low-shear delivery that preserves their integrity.

Available in both reusable and disposable formats, the PFSI™ adaps to different treatment schedules ranging from single-day courses to month-long regimens. With intuitive flow guidance and ergonomic design, drug delivery and lung deposition are optimised for each patient group, making every therapy not only effective, but also safe and convenient.

Manufacturing and Upscaling
From Concept to Global Supply

The PFSI™ is built on a platform designed for smooth translation from early-stage development to large-scale commercial production.

Its modular design enables rapid adaptation to different therapies without compromising quality or performance. Scalable processes, compatible with existing pharmaceutical infrastructure, ensure efficient manufacturing at every stage—from clinical batches to global supply.

Robust primary glass packaging maintains stability and sterility, while precision engineering guarantees consistent spray performance across every unit. With a future-ready production framework, the PFSI™ offers partners confidence in seamless upscaling, regulatory alignment, and reliable market delivery.

Protective Delivery for Sensitive Formulations
Protecting your Biologics From Fill to Patient

Gentle aerosolisation for mRNA, proteins, and complex modalities

The PFSI™ Soft Mist Inhaler is designed to protect fragile biologics and small molecules during pulmonary delivery. Leveraging low-shear Rayleigh nozzle technology and high-quality glass primary packaging, the system preserves molecular integrity throughout aerosolisation, making it ideally suited for mRNA-, protein-, and other complex therapeutic modalities.
