What is the primary effect of beclomethasone during treatment?

Beclomethasone is a corticosteroid that is primarily used for its anti-inflammatory properties. Its main effect during treatment is to reduce inflammation, particularly in conditions related to allergic reactions, asthma, or other respiratory issues. By inhibiting the release of inflammatory mediators, beclomethasone helps decrease swelling and redness in the airways, making it easier for patients to breathe. This action is crucial in managing chronic inflammatory conditions and preventing acute exacerbations.

The other options are not relevant to the mechanism of action of beclomethasone. For instance, improving digestion is not a characteristic effect of corticosteroids, nor is increasing blood flow or promoting urination, both of which relate to different physiological processes and medications. Thus, the primary effect of beclomethasone, which is to reduce inflammation, plays a vital role in its therapeutic use.
