In the case of a pregnant woman experiencing an acute asthma flare, which medication is most appropriate to adjust her regimen?

The appropriate choice for adjusting the medication regimen of a pregnant woman experiencing an acute asthma flare is prednisone. During pregnancy, managing asthma effectively is crucial for both maternal and fetal health.

Prednisone is a corticosteroid that is often utilized for its anti-inflammatory properties in severe asthma exacerbations. It can help reduce airway inflammation and improve lung function, making it a viable option during acute flare-ups. When prescribed in the lowest effective dose for the shortest necessary duration, prednisone is considered safe to use during pregnancy, particularly when the risks of poorly controlled asthma are weighed against the risks associated with the medication.

Other medications mentioned might not be the preferred choice during an acute asthma flare in a pregnant woman. Salmeterol, which is a long-acting bronchodilator, may not provide the rapid relief typically needed during an acute episode. Montelukast, a leukotriene receptor antagonist, serves as a maintenance treatment rather than immediate bronchodilation and may not be sufficient for acute situations. Tiotropium, an anticholinergic medication, is not first-line therapy and is generally not used for fast relief in acute asthma attacks.

Thus, the consideration of both the efficacy and safety profile during pregnancy makes adjusting the regimen with prednisone the most appropriate response for managing
