Which type of medication delivery system uses a spray format?

Aerosols are designed to deliver medication in a spray format, allowing for fine particles of medication to be inhaled or delivered to mucous membranes. This method of delivery is effective for conditions such as asthma or other respiratory issues where medication needs to reach the lungs directly. The aerosolization process helps in creating a mist that can easily be inhaled, which is essential for rapidly treating acute symptoms.

In contrast, injectables refer to medications delivered with a syringe or needle directly into the body, which is a very different method. Oral tablets are solid forms of medication meant to be swallowed, while transdermal patches deliver medication through the skin over an extended period. Each of these alternatives uses distinct mechanisms and formats that do not involve a spray delivery system.
