Often called "MDI". A device that allows delivery of medicine directly into the lungs. The medicine is in the form of a very, very fine powder, and a propellant is used to get the powder out in a cloud to be inhaled. Unfortunately, the propellant used in the standard MDI's is composed of CFC's (chlorofluorocarbons), which are involved in the destruction of the ozone layer. Different types of devices to deliver medicine to the lungs are now being designed, and some are already available to consumers (see DPI). For instructions on use of MDI's (as well as of the newer devices), go to Correct Use of Inhalers and Nebulizers (currently under construction.)
A small aerosol canister in a plastic container that releases a mist of medicine when pressed down from the top — This medicine can be breathed into the airway. Many asthma medicines are taken using an MDI.
A metal canister containing a drug formulation and propellants and placed in a plastic holder that precisely measures out a formulation dose for inhalation.
Delivery method for many asthma and some allergy medications that provides a precise puff of medicine into the lungs.
The most common device people use to take asthma medication. An MDI allows you to inhale a specific amount of medicine (a "metered dose"). It consists of a metal canister, which keeps the medication under pressure, and a plastic sleeve, which helps to release the medication. When you press the canister, medicine particles are propelled toward your throat where you can inhale them.
An inhaler that delivers a pre-measured dose of medicine in mist form into the mouth to be breathed directly into the lungs.

One of many inhalation devices used to inhale medication – often for asthma. Metered dose inhalers are compact, portable devices that deliver consistent doses. Alternate popular and portable ways to deliver inhaled medications are through Dry Powdered Inhalers (devices that break a capsule releasing a dry powder that is then inhaled). ( 4-21)
device which dispenses a specific amount of medication in aerosol or powdered form.
Small hand-held aerosol canister used to deliver inhaled drugs. Surprisingly enough, about 80-90% of an MDI dose is left in the mouth and throat, meaning only 10-20% of the dose makes it to the lungs. This is taken into account when a dosage is prescribed, so do NOT increase the dosage on your own to accommodate this. The 90% left in the patient's mouth consists of the larger particles that are too heavy to make the long trip to the lungs. These particles dissolve, are absorbed by tissue and then sent via the gastrointestinal system to the rest of the body. By using a spacer device such as an Aerochamber, you can reduce this effect since these larger particles are left in the Aerochamber rather than the mouth. Our spacer gets pretty well gunked up after a week or so - I clean it regularly. It is vitally important that the number of sprays emitted from a canister be tracked. Numerous studies have shown that MDI's lose their efficacy long before the canister is truly empty.
A metered dose inhaler (MDI) is a device that helps deliver a specific amount of medication to the lungs. It is commonly used to treat asthma, chronic obstructive pulmonary disease (COPD) and other respiratory problems.
