Dry Powder Inhaler Dry Powder Inhaler a device that contains a drug in dry powder form, and which when breath actuated, converts it into an aerosol cloud for inhalation
Stands for "dry powder inhaler". This is a variety of device that provides a new way of taking inhaled medicine. The propellants used in regular metered dose inhalers can be bad for the environment. For this reason, drug companies are in the process of switching over to DPI's, which do not use a propellant at all. The medicine is in the form of a very fine powder, which is easily inhaled without the use of an aerosol spray device. There are advantages for patients, too.
