Introflor-100 Oral



Solution for oral administration


Florfenicol is a synthetic broad-spectrum antibiotic that is effective against most Gram-positive and Gram-negative bacteria isolated from domestic animals. Florfenicol, a fluorinated derivative of chloramphenicol, acts by inhibiting protein synthesis at the ribosomal level and is bacteriostatic.
Florfenicol does not carry the risk of inducing human aplastic anaemia that is associated with the use of chloramphenicol, and also has activity against some chloramphenicol-resistant strains of bacteria.


Introflor-100 Oral is indicated for preventive and therapeutic treatment of gastrointestinal and respiratory tract infections, caused by florfenicol sensitive micro-organisms such as Actinobaccillus spp. Pasteurella spp. Salmonella spp. and Streptococcus spp. in swine and poultry. The presence of the disease in the herd should be established before preventive treatment. Medication should be initiated promptly when respiratory disease is diagnosed.
