Metered-dose Inhaler - Uses

Uses

Metered-dose inhalers are only one type of inhaler, but they are the most commonly used type. The replacement of chlorofluorocarbons propellants with hydrofluoralkanes (HFA) resulted in the redesign of metered-dose inhalers in the 1990s. For one variety of beclomethasone inhaler, this redesign resulted in considerably smaller aerosol particles being produced, and led to an increase of potency by a factor of 2.6.

• Asthma inhalers contain a medication that treats the symptoms of asthma.
• Dry powder inhalers involve micronised powder often packaged in single dose quantities in blisters or gel capsules containing the powdered medication to be drawn into the lungs by the user's own breath. These systems tend to be more expensive than the MDI, and patients with severely compromised lung function, such as occurs during an asthma attack, may find it difficult to generate enough airflow to get good function from them.
• A nicotine inhaler allows cigarette smokers to get nicotine without using tobacco, much like nicotine gum or a nicotine patch. Nicotine inhalers that are marketed as nicotine replacement therapy should not be confused with electronic cigarettes, which produce vapour and which are marketed mainly as devices that smokers can use in non-smoking areas. Nicotine inhalers are also known by their nickname of “the puffer”. These devices are made of thin plastic, sometimes resembling a cigarette, or a cylinder shape. It contains a porous nicotine filled plug, located in the base of the product. When you puff on the inhaler, nicotine vapor is inhaled and absorbed in the mouth’s lining. Every inhaler delivers almost four hundred puffs of this nicotine vapor. It is also considered healthier than the traditional cigarette, as it takes about eighty puffs to get an equal amount of nicotine that is acquired through only one cigarette. The nicotine inhaler is also temperature sensitive. In cooler weather, less nicotine is delivered. The Nicotine Inhaler is considered easier to use than the electronic cigarette as it is usually disposable, and contains less parts than the electronic cigarette.
