Abstract: The Invention relates to an anthelmintic composition for oral use comprising an effective amount of praziquantel and an effective amount of at least one anthelmintic agent selected from avermectins, milbemycins or derivatives thereof and to a method for controlling and treating infestations by cestodes and nematodes in equine animals comprising orally administering such a composition to said animals.
Abstract: A dosage form for orally administering chemical or medicinal substances such as vitamins, trace elements, amino acids, nutritive substances, vaccines, etc., to domestic or wild animals, and a method for preparing same, are disclosed. Said dosage form includes: a porous water-soluble central core containing binders selected from polypeptides, polysaccharides, polymers and colloids, and/or diluents selected from polyols, metal oxides, carbonates, phosphates and microcrystalline cellulose, and an effective amount of at least one bioactive substance; and a palatable hydrophobic outer layer containing at least one lipid substance selected from fatty alcohols, fatty acids, glycerol esters, hydrogenated oils, waxes, paraffin, lanolin, coconut oil and fatty acid salts; a polymeric agent for modulating the disintegration and adhesion of said outer layer, and natural or synthetic palatable substances.

Abstract: There is disclosed a novel device intended to permit the regular and continuous release of chemical substances, including medicaments, and this, over a very long period of time, the release of the active substances following a predetermined kinetic effect from an insoluble polymeric matrix to a liquid medium which can be, particularly, that of an animal or human organism. The device has a specific density to remain in an animal rumen. There is also disclosed a method for treating animals by means of such devices.
