Question: 1 / 400

What is the main organ affected by drugs targeting Beta-2 receptors?

Heart

Lungs

Drugs that target Beta-2 receptors primarily affect the lungs. Beta-2 adrenergic receptors are a type of adrenoceptor that, when stimulated, cause relaxation of bronchial smooth muscle. This makes them particularly important in the treatment of conditions such as asthma and chronic obstructive pulmonary disease (COPD), where bronchodilation is necessary to improve airflow and alleviate symptoms.

Activation of Beta-2 receptors leads to the dilatation of airways, making it easier for individuals to breathe. This is why medications such as albuterol, which are selective Beta-2 agonists, are commonly prescribed for respiratory issues. The other options do not primarily involve the Beta-2 receptor mechanism; the heart primarily concerns Beta-1 receptors, while the digestive system and kidneys are not significantly influenced by Beta-2 receptor activity in the same way as the lungs.
