Which inhaled medication listed uses lactose as a carrier?

The use of lactose as a carrier is specifically associated with formulations of certain inhaled medications, predominantly those that are dry powder inhalers. In the context of Foradil (Formoterol), it is known that lactose serves as a carrier for the active ingredient, enabling the medication to be delivered effectively to the lungs when inhaled. Lactose is commonly utilized in inhalation products to improve the flow and dispersion of the powder, ensuring that a consistent dose reaches the airways.

Other medications listed, such as Advair, Budesonide, and Salmeterol, may have different formulations that do not utilize lactose as a carrier or may be delivered via alternative mechanisms, such as metered-dose inhalers (MDIs) or nebulizers, which do not require lactose as a powder carrier. Thus, the presence of lactose as a carrier makes Foradil (Formoterol) the correct choice in this instance, underscoring the importance of understanding the formulation characteristics of inhaled asthma medications.
