Tylan®

Background

Tylosin is a bacteriostatic, time-dependent macrolide antibiotic with good activity against Gram-positive aerobes. There is somewhat less activity against Gram-negative aerobes, but good activity against Pasteurellaceae. Tylosin is not effective against Pseudomonas aeruginosa and most Enterococcus spp. Distribution is wide, and excretion is primarily as unchanged drug in bile and urine.

Acceptable Uses

  • Treatment of campylobacteriosis, clostridial diarrhea, or cryptosporidioisis.
  • Treatment of upper respiratory tract disease associated with Mycoplasma or Chlamydia spp.
  • Control (but not necessarily cure) of inflammatory bowel disease or idiopathic antibiotic-responsive diarrhea.

Unacceptable Uses

  • Low doses of tylosin was previously used to prevent or reduce tear-staining (secondary to epiphora). This is now considered irresponsible antimicrobial use and the FDA has removed all tylosin products used solely to treat tear-staining from the market.

  • Tylan 200mg/ml injectable suspension

Notes

  • Erythromycin is used to predict susceptibility.
