Which drug is classified as an anti asthmatic steroid?

Fluticasone propionate is classified as an anti-asthmatic steroid, also known as a corticosteroid. This type of medication is used to reduce inflammation and swelling in the airways, making it easier for asthma patients to breathe. Corticosteroids work by mimicking the effects of hormones produced by the adrenal glands, helping to control allergic and inflammatory responses in the body. In the context of asthma, reducing airway inflammation is crucial to managing symptoms and preventing asthma attacks.

The other medications listed serve different purposes. Insulin Detemir is a long-acting insulin used to manage blood sugar levels in people with diabetes. Doxazosin Mesylate is primarily used to treat high blood pressure and symptoms of benign prostatic hyperplasia, not asthma. Amoxicillin with Clavulanate Potassium is an antibiotic combination used to treat various bacterial infections, thus not related to asthma treatment. Understanding the specific classifications and uses of these medications highlights why Fluticasone propionate is the correct answer in the context of anti-asthmatic therapy.
