What is the function of a bronchodilator?

A bronchodilator is a type of medication primarily used to relax and widen the airways in the lungs, which helps to improve airflow and ease breathing. This is particularly important for individuals with respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), where airway constriction can lead to difficulty in breathing.

By opening constricted airways, bronchodilators alleviate symptoms like shortness of breath, wheezing, and coughing associated with these conditions. This function is critical for maintaining adequate oxygenation and overall respiratory health.

Other options listed serve entirely different purposes. Reducing fever is typically achieved with antipyretics, suppressing coughing generally involves the use of cough suppressants, and managing blood clotting relates to anticoagulants or antiplatelet medications. Each of these options addresses separate medical needs and is not related to the primary action of bronchodilators.
