A small device for administering medicinal substances into the mouth or nose so that they can be breathed in.
Device used to deliver medication in an aerosol form that can be inhaled by people with asthma or other respiratory diseases. Inhalers are small, portable, and practical. They are used to deliver measured doses of drugs that improve breathing by dilating the airways. The types of antiasthma medication that are delivered by inhalers include bronchodilators, corticosteroids, and cromolyn sodium.
A mechanism for administering a drug in the form of a powder or aerosol. mainly used by patients with asthma. Inhalers are basically of two types: aerosol, and dry-powder inhaler. The former delivers the drug as an aerosol spray when the patient presses the top of the canister containing the drug; the latter works by putting a drug capsule in the end of the chamber and, when the patient presses the top, the capsule is pierced and the drug released. A variety of ‘spacing devices’ are available for use with pressurized (aerosol) inhalers, providing metered doses. The space introduced between the inhaler and the mouth reduces the velocity of the aerosol and thus the impact it has on the throat. More time is thus allowed for evaporation of the propellant, with a greater concentration of drug particles being inhaled into the air tubes and lungs. Devices with larger spacing devices and a one-way valve are very effective and particularly useful for children and patients needing higher doses of the drug.
A device for administering medicines by inhalation.
An inhaler is a device utilized for administering drugs in the form of powder or vapor. It finds primary use in treating various respiratory disorders, including asthma and chronic bronchitis. Metered-dose inhalers offer a precise dose when pressed. Inhalation drugs encompass bronchodilators and corticosteroids.
