NAME OF THE VETERINARY MEDICINAL PRODUCT Coldostin, 4800000 IU/g, powder for use in drinking water/milk 2. QUALITATIVE AND QUANTITATIVE COMPOSITION Each gram contains: ACTIVE SUBSTANCE_:_ Colistin sulfate 4 800 000 IU EXCIPIENTS: For the full list of excipients, see section 6.1. 3. PHARMACEUTICAL FORM Powder for use in drinking water/milk. White to off-white powder. 4. CLINICAL PARTICULARS 4.1 TARGET SPECIES Cattle (calves), sheep (lambs), pigs, chickens and turkeys. 4.2 INDICATIONS FOR USE, SPECIFYING THE TARGET SPECIES Treatment and metaphylaxis of enteric infections caused by non-invasive _Escherichia coli_ susceptible to colistin sulfate. In the case of metaphylaxis, the presence of the disease in the group must be established before the product is used. 4.3 CONTRAINDICATIONS Do not use in cases of hypersensitivity to colistin sulfate or to any of the excipients. Do not use in cases of resistance to polymyxins. Do not use in horses, particularly in foals, since colistin sulfate, due to a shift in the gastrointestinal microflora balance could lead to the development of antimicrobial associated colitis (Colitis X), typically associated with Clostridium difficile, which may be fatal. 4.4 SPECIAL WARNINGS FOR EACH TARGET SPECIES As an adjunct to treatment, good management and hygiene practices should be introduced in order to reduce the risk of infection and to control the potential build-up of resistance. There is cross-resistance between colistin sulfate and polymyxin B. Colistin sulfate exerts concentration-dependent activity against Gram-negative bacteria. Following oral administration high concentrations are achieved in the gastrointestinal tract, i.e. the target site, due to the poor absorption of the substance. These factors indicate that a longer duration of treatment than the one indicated in section 4.9, leading to unnecessary exposure, is not recommended.
