Seretide Diskus 50/250 mcg contains two medicines: salmeterol and fluticasone propionate. Salmeterol is a long-acting bronchodilator. Bronchodilators help the airways in the lungs to stay open. This makes it easier for air to get in and out. The effects last for at least 12 hours.
Ventolin (salbutamol) is used by patients suffering from various respiratory conditions, including asthma, emphysema, and chronic obstructive pulmonary disease. It can also be used to prevent breathing difficulties (bronchospasm) during exercise.
