Bronchodilators and Bronchospasms
Recently the term "bronchospasm" has become more frequent when naming the cause of asthma attack, but these terms are basically one and the same. In over 95% cases an asthma attack happens when the muscles around the airways suddenly tighten, causing immediate worsening of symptoms such as cough, difficulty breathing, shortness of breath and others - a reaction that is called a bronchospasm. Usually, bronchospasms are triggered by inhaling an allergen or irritant that the person is especially sensitive to, which is why they happen so suddenly. A bronchospasm can also be caused by several other things, such as physical activity, depression or exhaustion, and by emotional states - fear, anger, laughter, anxiety and others. Medical studies indicate that a bronchospasm can go away on its own, but it is only possible if the negative effects it stimulates are not dangerous or life threatening. Not all asthma patients have asthma attacks severe enough to endanger life or wellbeing, but these cases do happen. On such an occasion, the only option is to artificially relax the muscles constricted by a bronchospasm. This can be done fairly easy using a bronchodilator such as Ventolin (albuterol). A bronchodilator is basically a drug that works by instantly relaxing the muscles around the airways. Ventolin inhaler as well as other drugs in this class stimulate specific receptors in the body which causes an immediate relaxation of airway muscles and relief of symptoms.
