Asthma is a global health problem that can occur in all age groups, the prevalence of which is increasing in many developing countries. Two classes of drugs commonly used in the treatment and control of asthma are anti-inflammatory corticosteroids and bronchodilators.
1. In which case do you use an inhaler to control asthma?
In asthma control, the drug can be used orally, by inhalation, or even by injection, but the most common, convenient and effective is still using an inhaler / inhaler device. This form of medicine can generally be used in two cases: to relieve asthma attacks or to control and prevent asthma.
Asthma relief: medicine used to relieve symptoms when an asthma attack occurs (such as cough, wheezing, shortness of breath, pain, tightness in the chest). Asthma control/prophylaxis: medications are routinely used for a long time to treat symptoms and prevent asthma attacks from occurring.
2. Advantages of inhaled inhalers in asthma management
Inhalation sprays are aerosolized form of drugs that are delivered directly into the respiratory tract through the mouth, thus creating a faster effect than oral or aerosol drugs. This is especially important in stopping an asthma attack. The drug is delivered via inhalation to the lungs thereby reducing many of the systemic side effects. The lungs are also the target of the drug, so the dose of the drug to be treated is smaller than that of other routes of the same active ingredient.
The multi-use inhaler device is compact, suitable for hand-held and carried around, and designed to hold multiple doses. An asthma attack can happen at any time, so being able to carry it with you wherever you go is a huge advantage of an inhaler.
