- the invention relates to a hydrous suspension formulation comprising a coarse-grained carbon adsorbent which is suitable for binding and removal of harmful substances from the gastrointestinal tract, and to a water-soluble or water-dispersible structuring agent and a humectant.
- these activated carbons are used as dry granules.
- this dry application form is only conditionally suitable because it does not mix homogeneously with dry foods.
- the application to dry food is an essential prerequisite for the commercial success of such a product in animals.
- a liquid or pasty formulation containing the adsorbent can be combined with any type of feed.
- the most important requirements for such a formulation are that the adsorption properties are not unduly reduced and the palatability of the food or feedstuff is not restricted by the composition and consistency nor by the dose volume, even in the case of accidental overdosage or top dressing.
- Formulation based on a water-soluble carrier which mixes with oral administration without problems with the aqueous media of the gastrointestinal tract and the adsorbent is rapidly distributed freely for the adsorption of toxins dissolved in the aqueous medium. good compatibility even with permanent administration

- these adsorbents have a spherical shape, an ideal spherical shape is not necessarily feasible in practice, therefore, “spherical” particles should also be understood as meaning approximately spherical particles.
- the carbon adsorbents used according to the invention preferably have a specific surface, determined by the BET method, of 700 m 2 / g or more, more preferably 800 m 2 / g or more.
- the carbon adsorbents may have functional groups.
- they may have acidic groups which are preferably present in a total amount of 0.30 to 1.20 meq / g, in particular 0.30 to 1.00 meq / g.
- the adsorbents may have basic groups, which are preferably present in a total amount of 0.20 to 0.70 meq / g, in particular 0.30 to 0.60 meq / g.

- these have a total amount of 0.30 to 1.20 meq / g, in particular 0.30 to 1.00 meq / g of acidic groups and a total of 0.20 to 0.70 meq / g, especially 0.30 to 0.60 meq / g of basic groups, with 0.20 to 0.70 meq / g of phenolic hydroxyl groups and 0.15 meq / g or less of carboxyl groups.
- the ratio (a: b) of the total amount of acidic groups (a) to the total amount of basic groups (b) is 0.40 to 2.5.
- the value of [(b + c) -d] for the total amount of basic groups (b), the amount of phenolic hydroxyl groups (c) and the amount of carboxyl groups (d) is preferably 0.60 or more (amounts in meq / g).
- the carbon adsorbents preferably have a pore volume of the pores with a diameter of 20 to 15 000 nm of 0.04 mL / g to 0.1 mL / g, preferably 0.05 mL / g to 0.1 mL / g.
- the formulations according to the invention usually contain 10 to 80% m / V, preferably 20 to 60% m / V, particularly preferably 30 to 50% m / V carbon adsorbent.
- % m / V mass of the respective ingredient in grams per 100 mL of the final formulation.
- the formulations usually contain 1 to 95% m / V, preferably 5 to 60% m / V, more preferably 10 to 40% m / V water.
- the humectant is usually liquid to viscous and water soluble.
- Humectants are preferably used di- or trihydric alcohols having 2 to 10, preferably 3 to 6 carbon atoms, for example, glycerol, ethylene glycol, Diethylene glycol or propylene glycol. Preference is given to propylene glycol and in particular glycerol.
- the humectant is usually contained in the formulations in an amount of 10 to 95% m / V, preferably 50 to 80% m / V.
- the formulations according to the invention also contain a water-soluble or water-dispersible structuring agent, which generally forms a yield-limit gel structure in the suspension formulations. It was found that the addition of a structuring agent improves the stability, in particular the long-term stability of the formulations, which is not easy with the relatively coarse-grained adsorbent.
- suitable structuring agents may be mentioned in particular: cellulose derivatives, such as. Methylcellulose, carboxymethylcellulose, sodium carboxymethylcellulose, hydroxyethylcellulose, polymeric carbohydrates, such as. Xanthan gum, alginate, gum arabic, pectins; Polypeptides, such as. As gelatin, casein, and polyvinylpyrrolidone (PVP), ethyl acrylate and methyl methacrylate copolymers or polyacrylic acid and mixtures of such components.
- PVP polyvinylpyrrolidone
- the structuring agent is usually present in amounts of 0.2 to 15% m / V, preferably 0.5 to 10% m / V, particularly preferably 1 to 5% m / V. If a mixture of structuring agents is used, the above information refers to the total amount.
- the formulation of the invention may contain other conventional pharmaceutical ingredients, such as.
- food dyes and / or pigments such as titanium dioxide or iron oxide.
- pigments are usually contained in amounts of 0.1 to 10% m / V, preferably 0.2 to 8% m / V.
- the formulation may also contain conventional preservatives, such as. B. sorbic acid optionally in combination with ascorbic acid. Standard concentrations are used which are familiar to the expert, such as. From 0.01 to 1% m / V.
