Description
The combination of colistin and trimethoprim acts additive. Colistin is an antibiotic from the group of polymyxins with a bactericidal action against Gram-negative bacteria like E. coli, Haemophilus and Salmonella spp. Since colistin is absorbed for a very small part after oral administration only gastrointestinal indications are relevant. Trimethoprim is an antibacterial agent with a bacteriostatic action against many Gram-negative and Gram-positive bacteria like E. coli, Haemophilus, Pasteurella, Salmonella, Staphylococcus and Streptococcus spp. After oral administration trimethoprim is absorbed almost totally and penetrates well into tissues and cells.
