Advair/Seretide (salmeterol and fluticasone propionate) is a combination inhaler that treats asthma and COPD by combining a long-acting bronchodilator with an anti-inflammatory corticosteroid. This dual-action medication provides both immediate symptom relief and long-term disease control, making it effective for patients whose conditions arent adequately managed with single-agent therapy. For patients seeking affordable respiratory medications, working with qualified healthcare providers ensures proper inhaler technique training, appropriate dose selection, and ongoing monitoring for both therapeutic effectiveness and potential side effects associated with combination respiratory therapy management.
