Course overview

This interactive seminar will provide a comprehensive overview of metered-dose inhaler technology, giving participants a valuable insight into market potential and recent industry trends. The programme will clarify the therapeutic targets and look at the various delivery technologies available. There will be detailed coverage of the manufacturing process, equipment and options, together with quality and inspection requirements, human factors and bioequivalence. Our highly experienced trainer will address the regulations applying to inhalation products and provide guidance on the regulatory pathways to follow.

The event will benefit those new to this area and will also be of value to anybody who requires a refresher on the opportunities available with this technology. The seminar format will include practical workshops, which past delegates have found invaluable, and ample opportunity for discussion on any specific issues with an expert in this field.
