Expert Understanding of Inhaled Formulation Systems and Device Compatibility

Developing and commercializing new inhaled drug products requires deep scientific understanding through a continuous focus on testing, data collection, and expert analysis. We can help through ‘hands-on’ testing support integrated with consultancy on inhaled product development through all pre-clinical and clinical development stages.

Flexible OINDP Testing and Development

If you develop, manufacture, or test orally inhaled and nasal drug products (OINDPs), we can help.

Our end-to-end service spans early-stage product characterization and analysis, device selection and testing, and extends to manufacturing validation, cleaning instructions, and small-scale manufacturing. Our consultants have a proven track record in aerosol science, inhaler development, the planning and execution of clinical programs, and successful regulatory filings.

Working with us is like recruiting your own specialist respiratory scientific team. We offer state-of-the-art technologies, general-purpose analytical testing, expertize in device verification testing, and an excellent understanding of inhaled formulation systems and device compatibility.

With years of in-house and consultancy experience in inhalation and aerosol science, device optimization, and novel device regulatory projects, our consultants can give expert guidance on efficient, cost-effective testing approaches for novel products and formulations to ensure regulatory approval.

Whitepaper: Improving the Sustainability of Pressurised Metered Dose Inhalers

Since their introduction in 1956, pressurised metered dose inhalers (pMDIs) have become the dominant treatment choice for patients suffering from common respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). However, unbeknown to most patients and many doctors, pMDIs account for 3.9% of NHS’s annual carbon emissions. 1Here we will discuss how formulation changes might be the answer to the pMDI-related sustainability problem.
