Do You Have These Asthma Symptoms? Get The Facts On Effective Treatment For Asthma Symptoms

Asthma is a chronic lung condition with narrowed and inflamed airways caused as a result of hypersensitiveness to some allergens. The symptoms of asthma vary from person to person and in any individual from time to time. Many symptoms may be subtle and are also present in other respiratory conditions thus making diagnosis difficult. The four major recognized symptoms in asthma are shortness of breath with exertion, wheezing, cough that may be chronic or may occur when exposed to cold, dry air and chest tightness.

Most asthma medications work by relaxing bronchospasm (bronchodilators) or reducing inflammation (corticosteroids). Inhaled medications are preferred as they act directly on the airway surface and airway muscles where the asthma problems initiate and absorption of inhaled medications into the rest of the body is minimal. Inhaled medications include beta-2 agonists, anticholinergics, corticosteroids, and cromolyn sodium. Beta-2 agonists are inhaled bronchodilators which are called agonists because they promote the action of the beta-2 receptor of bronchial wall muscle. This receptor acts to relax the muscular wall of the airways (bronchi), resulting in bronchodilation. The bronchodilator action of beta- 2 agonists starts within minutes after inhalation and lasts for about four hours. Albuterol, metaproterenol, terbutaline sulfate are some beta-2 agonists.

The anticholinergic agents act on a different type of nerves than the beta-2 agonists to achieve a similar relaxation and opening of the airway passages. Ipratropium bromide is a commonly used anticholinergic agent. These two groups of bronchodilator inhalers when used together can produce an enhanced bronchodilation effect.

When symptoms of asthma are difficult to control with beta-2 agonists, inhaled corticosteroids are often added. Corticosteroids can improve lung function and reduce airway obstruction over time. Examples of inhaled corticosteroids include beclomethasone dipropionate. Expectorants are also used to thin airway mucus, making it easier to clear the mucus by coughing. For patients with atopic asthma, in addition to bronchodilator medications, avoiding allergens or other irritants is very important.

In patients who cannot avoid the allergens, or in those whose symptoms cannot be controlled by medications, allergy shots are considered. In patients with severe asthma, inhaled medications are unlikely to reverse the process and a mechanical ventilator may be needed to assist the lungs and respiratory muscles. A face mask or a breathing tube is inserted in the nose or mouth for this treatment. When asthma is unresponsive to treatment with an inhaler, patients should promptly seek medical attention at the closest hospital emergency room or their asthma specialist office.
