Tasted masked veterinary solid compositions

Abstract

The present invention relates to the supply and production of an animal medicine consisting of a substrate in pellet or tablet form, which is attractive to livestock and domestic animals, in which fine-grained particles of a neutral-tasting, physiologically compatible, solid carrier material are embedded, which is characterised in that said fine-grained particles of carrier material have an average diameter of 0.09 to 0.8 mm and are coated with an active substance from veterinary medicine, and said active substance layer is covered with a protective layer of a physiologically compatible polymer matrix, and to the production of this animal medicine. It also relates to the usage of said double-coated, fine-grained particles of carrier material in the production of a preparation for veterinary medicine.

1 - 20 . (canceled)  
     
     
         21 . An animal medicine in pellet or tablet form comprising: 
 a substrate, whereby said substrate consists of animal feed; and    coated particles whereby said substrate and said coated particles are intimately mixed and whereby said coated particles comprise 
 a carrier material having an average diameter of approximately 0.8 mm or less;  
 an active ingredient casing comprising at least one veterinary active ingredient whereby said active ingredient casing coats said carrier material; and  
 a masking protective layer whereby said masking protective layer coats said active ingredient casing.  
   
     
     
         22 . The animal medicine of  claim 21  whereby said carrier material has an average diameter of approximately 0.09 mm and 0.8 mm.  
     
     
         23 . The animal medicine of  claim 21  whereby said carrier material is selected from the group consisting of cellulose, starch, saccharose, lactose, and sugar.  
     
     
         24 . The animal medicine of  claim 21  whereby said masking protective layer is selected from the group consisting of shellac, a cellulose polymer, an acrylic acid polymer, a methacrylic acid polymer, a maleic acid anhydride polymer, a polyvinyl pyrrolidone polymer, a polyvinyl alcohol polymer, or a combination of said polymers.  
     
     
         25 . The animal medicine of  claim 21  further comprising one or more additives whereby said additives are selected from the group consisting of proteins, vitamins, minerals, artificial aromatics, and natural aromatics.  
     
     
         26 . The animal medicine of  claim 21  whereby said substrate consists of lysed yeast.  
     
     
         27 . The animal medicine of  claim 21  whereby said veterinary active ingredient is selected from the group consisting of anti-parasitic, anti-bacterial, anti-viral, and neurotropic.  
     
     
         28 . The animal medicine of  claim 27  whereby said veterinary active ingredient is benazepril.  
     
     
         29 . A method of making an animal medicine comprising 
 coating a carrier material with at least one veterinary active ingredient whereby said carrier material has an average diameter of approximately 0.8 mm or less;    coating said at least one veterinary active ingredient with a masking protective layer to form coated particles;    intimately mixing said coated particles with a substrate whereby said substrate consists of animal feed; and    compressing said intimately mixed coated particles and substrate into tablets or pellets of appropriate size.    
     
     
         30 . The method of  claim 29  whereby said carrier material has an average diameter of approximately 0.09 mm to approximately 0.8 mm.  
     
     
         31 . The method of  claim 29  whereby said carrier material consists of cellulose, starch, saccharose, lactose or sugar.  
     
     
         32 . The method of  claim 29  whereby said masking protective layer is selected from the group consisting of shellac, a cellulose polymer, an acrylic acid polymer, a methacrylic acid polymer, a maleic acid anhydride polymer, a polyvinyl pyrrolidone polymer, a polyvinyl alcohol polymer, or a combination of said polymers.  
     
     
         33 . The method of  claim 29  further comprising adding one or more additive to said intimately mixed coated particles and substrate whereby said additive is selected from the group consisting of proteins, vitamins, minerals, artificial aromatic substances, and natural aromatic substances.  
     
     
         34 . The method of  claim 29  whereby said substrate consists of lysed yeast.  
     
     
         35 . The method of  claim 29  whereby said veterinary active ingredient is selected from the group consisting of anti-parasitic, anti-bacterial, anti-viral, and neurotropic.  
     
     
         36 . The method of  claim 35  whereby said veterinary active ingredient is benazepril.
