Dear Dr.Ram,
thanks a lot for useful information and comparison of different surfactant medications. We use Curosurf also. My field of interesting is surfactant replacament therapy, therefore I paid my attention about few articles about Infasurf, but a lot of about Survanta, Curosurf. May be nobody don't use Infasurf due to insufficient of SP-B,SP-C concentration and phospholipid fraction or any other clinical reasons.
