Pharmaceutical Aerosols, Dry Powder Inhalation Systems and Nasal Delivery Devices

Register InterestNo Course Dates Currently Available


The purpose of the Course is to provide a sound background in aerosols generally and metered inhalers and dry powder devices, specifically. Since none of these product administration systems can be developed in isolation, a high level of integration is required between product, pack/device so that an adequate performance and shelf life can be achieved by effective testing procedures. This involves a thorough knowledge of formulations and the materials (metal, plastics, rubbers, etc.) from which the pack/device component may be produced. The aim of the Course is to provide information across these diverse areas.


Three Day "Team Taught" Intensive Course for Scientists, Managers and Technicians

Pharmaceutical aerosols, (particularly as metered dose inhalers (M.D.I."s) and dry powder inhalation systems, have over recent years, shown a steady growth in conjunction with nebulisers and nebulisation systems. More recently nasal delivery devices are increasingly being used as novel drug delivery systems. The advantages and disadvantages of all these devices will be compared, with M.D.I's and dry powder inhalation systems being covered in detail from development through marketing, launch and patient use.

The increasing demands of the world"s regulatory authorities in terms of product performance, safety and quality and how this has led to more sophisticated testing procedures together with a rational approach to product evaluation and supporting documentation will be reviewed.

Who Should Attend?

The Course is designed to provide a broad knowledge base on aerosols and dry powder devices with limited reference to nebulisers. It is therefore intended for those who require an overview of the technologies involved as well as those who require specialised knowledge of more specific areas, ie. R & D, Development, Production, QA, QC and Regulatory Affairs.
