Pulmonary surfactants are drugs that act as components of alveoli, one of the lungs, to transport oxygen and other nutrients into the bloodstream. These drugs play a crucial role in maintaining healthy lung function by blocking the passage of gases from the alveoli through thin airways.
(What Does Pulmonary Surfactant Do?)
One of the main mechanisms by which pulmonary surfactants work is by forming an array of complex molecules called surfactant proteins. These proteins bind to surfaces on the surface of tiny cells called microstasis cells within the lungs, such as capillaries, and then trigger a chemical reaction that activates the receptor for extracellular CO2, which is the molecule released by the lungs during breathing.
Another mechanism by which pulmonary surfactants work is by producing pro-inflammatory substances like leukotensin and interleukin-6 (IL-6). IL-6 is involved in regulating immune responses and can help prevent infections, while leukotensin is a neurotransmitter that helps recruit blood vessels to the lungs and stimulate inflammation.
Pulmonary surfactants also have anti-inflammatory properties that help reduce inflammation in the lungs. They can be used to treat conditions such as asthma, bronchitis, and lung cancer by reducing inflammation and improving airflow to the lungs.
However, there are some potential downsides to using pulmonary surfactants. One of the main concerns is that they may cause serious side effects if not used properly. For example, inhaling too much surfactant or when taking them at high doses can cause increased heart rate, shivering, and even blood clots. It’s important to follow the instructions for use carefully and take only the amount of pulmonary surfactant that is needed for the task at hand.

Overall, pulmonary surfactants play an important role in maintaining healthy lung function by blocking the passage of gases from the alveoli through thin airways. While there are some potential downsides to using these drugs, they can also provide significant benefits in treating certain conditions.
