Which of the following medications is used primarily for asthma?

Ventolin HFA is primarily used for treating asthma as it contains albuterol, a bronchodilator that works by relaxing the muscles in the airways and increasing airflow to the lungs. It is often utilized during asthma attacks to relieve symptoms such as wheezing and shortness of breath. Patients with asthma may also keep it on hand for use before exercise to prevent exercise-induced bronchospasm.

The other medications listed serve different purposes. Benadryl, an antihistamine, is typically used for allergies and is not indicated for asthma treatment. Flonase is a nasal spray containing fluticasone, used primarily to manage symptoms of allergic rhinitis rather than asthma. Dulcolax is a laxative used for relieving constipation and has no role in managing respiratory conditions like asthma. Understanding the specific uses and mechanisms of these medications is crucial in effectively managing patient care in pharmacy practice.
