Tilmicosin is a broad-spectrum semi-synthetic bactericidal macrolide antibiotic synthesized from tylosin. It has an antibacterial spectrum that is predominantly effective against Mycoplasma, Pasteurella and Haemophilus spp. and various Gram-positive organisms such as Corynebacterium spp. It is believed to affect bacterial protein synthesis through binding to 50S ribosomal subunits. Cross-resistance between tilmicosin and other macrolide antibiotics has been observed. Following oral administration, tilmicosin is excreted mainly via the bile into the faeces, with a small proportion being excreted via the urine.

Indications

Macrotyl-250 Oral is indicated for the control and treatment of respiratory infections associated with tilmicosin-susceptible micro-organisms such as Mycoplasma spp. Pasteurella multocida, Actinobacillus pleuropneumoniae, Actinomyces pyogenes and Mannheimia haemolytica in calves, chickens, turkeys and swine.
