An alternate technology to MDIs that can be used if the medication being dispensed can be satisfactorily formulated as microfine powder, thus eliminating the use of a chemical propellant.
Similar to an MDI in that it delivers a precisely-measured dose of medicine into the lungs, however it is the patient's inhalation that triggers the medicine's release rather than the press of the canister. The medicine itself is in the form of a dry powder; currently Intal is available in the US in this form.
Medication device that contains a dry powder. These types of medications need to be inhaled quickly, as opposed to the pressurized inhalers that spray the medicine out and need to be inhaled slowly.
a hand held device used to bring medicine into the lungs
A small device similar to a metered dose inhaler, but where the drug is in powder form. The patient exhales out a full breath, places the lips around the mouthpiece, then quickly breathes in the powder. Dry powder inhalers do not require the timing and coordination that are necessary with MDIs.
a mechanism that delivers powdered medication to the lungs.
A portable device used to deliver dry powdered medication to the lungs; single and multi-dose models are available; no propellant is required; all models are breath-actuated and require no hand-lung coordination.
A small device for administering inhaled medication for asthma. The medication in these inhalers is in the form of a dry powder that must be inhaled. There is no device or gas to propel the powder (Aerolizer®, Diskhaler®, Diskus®, Turbuhaler®).
A device for inhaling respiratory medications that come in powder form.
