Why Micotil Works

Micotil is a proven, long-lasting BRD treatment that offers flexible, cost-effective dosing for both metaphylaxis and individual pull-and-treat therapy. Explore below how it impacts the lungs, respiratory tract and immune cells in cattle after just one dose.

Alveolar macrophages, the primary defence mechanism in the lower respiratory tract. engulf pathogens, kill and digest them. * They recruit neutrophils through cytokine release.

A Timeline Of Micotil


  • Micotil reaches cattle’s lungs in 1 hour1,2
  • Micotil reaches consolidated lungs in 2 hours1,2



  • Micotil stays at effective levels for 3 to 4 days through the respiratory tract, including pneumonic lung tissue,1,2 tracheal mucosa3 and where the respiratory infectious process begins - the tonsils3



  • Micotil maintains levels in alveolar macrophages3 and neutrophils4 for up to 10 days
  • These immune cells deliver Micotil when and where it's needed most - at the site of the infection
