Bronchodilators: a remedy for acute Asthma symptoms

One of the most common medications that is used to treat asthma is the bronchodilator. Quick-acting bronchodilators are used only for the rapid “rescue” of asthma in an acute attack. And long-acting bronchodilators are taken daily to control the course of the disease. Bronchodilators expand the bronchi, which ensures a normal circulation of oxygen. Bronchodilators also help clear the lungs of mucus. Since the airways are open, the mucus freely moves and easily expectorates.

What type of bronchodilator stops the exacerbation of asthma symptoms?

There are three types of bronchodilators:

  1. beta-agonist;
  2. anticholinergic;
  3. theophylline.

These medications can be in the form of inhalers, tablets, liquid medications, and injections, but the best way to take a beta-agonist and anticholinergics through inhalers.

What is fast-acting bronchodilator?

Fast-acting bronchodilators are called “for relief of symptoms”, instantaneous or “analgesic” remedies. Bronchodilator quickly removes the severity of the attack, opening the airways. Instant drugs are used for sudden exacerbation of the disease. Inhalation medicine begins to act a few minutes after inhalation and the effect last 2-4 hours. Bronchodilators in inhalers should be taken 15-20 minutes before the onset of physical exertion (with asthma stress).

Quick-acting bronchodilators can also be used in aerosols to stop an asthma attack at home. As for tablets, they have much fewer advantages compared to inhalers. Since they have many side effects due to the fact that tableted bronchodilators need to be taken in large doses and before they enter the lungs they pass through the blood. And inhalation bronchodilators fall directly into the lungs and cause fewer side effects.

An overdose of rapid bronchodilators, in inhalers, tablets or in liquid form, is a sign of an unstable course of the disease, which requires more aggressive intervention. If you have to use the bronchodilator more than twice a week, consult a doctor about changing the treatment program.

What is long-acting bronchodilator?

Long-acting bronchodilators are used to maintain asthma at a specific level (and not for a quick stopping of an attack). The action of the bronchodilator lasts up to 12 hours. Those bronchodilators, which contain formoterol, begin to act after a few minutes, and those that contain salmeterol – after 45 minutes.

Long-acting bronchodilators should be taken twice a day. But regular use of bronchodilators without an additional inhaled steroid increases the risk of death. For more detailed information, read the instructions.

  • Nervousness
  • Overexcitation or hyperactivity
  • Cardiopalmus
  • Stomach upset
  • Problems with sleep (insomnia)
