The Science

While our motivation is simple, the science that goes into creating a lung surfactant that resembles the real thing is a little more complicated.

Infasurf® (calfactant), made to do more.

Infasurf® (calfactant) is the only natural, FDA approved surfactant manufactured in the U.S. by a unique calf lung lavage method. This process yields a surfactant that closely mirrors native calf lung surfactant in both composition and activity.
