The object of the present invention is a pharmaceutical formulation of racecadotril characterized by high bioavailability. In particular, the present invention relates to a method of dry granulating racecadotril in the presence of a hydrophilic excipient and a disintegrant, preferably with a low moisture content; said method being carried out by means of a tablet machine or alternately a roller compacting machine, carrying out the compaction step with a compaction strength of less than 30 kN and equal to or greater than 4 kN, and the step of grinding the slugs and screening so as to obtain a granulate in which not more than 50% by weight of the product has a particle size of less than 90 micron.
