Pharmaceutical Aerosols, Dry Powder Inhalation Systems and Nasal Delivery Devices

Register Interest

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.
