1. A buffered digestive enzyme/bile salt composition for the treatment of digestive enzyme/bile salt deficiency of mammals comprising, by weight per weight percentages based on the total weight of the composition:

  • a) from about 10 to about 90.0% of a concentrate of an enzyme selected from the group consisting of pancreatic proteases, pancreatic lipases, pancreatic nucleases and pancreatic amylases;

    b) from about 0.3 to about 75% of a bile salt in powder form;

    c) from about 7.35 to about 40.50% of a buffering agent selected from the group consisting of anhydrous sodium carbonate, sodium bicarbonate, potassium carbonate, ammonium carbonate, tromethamine, di(tris(hydoxymethyl)aminomethane) carbonate, tris-glycine, di-arginine in the molecular weight range of 350 to 50,000 daltons, tri-arginine in the molecular weight range of 350 to 50,000 daltons, poly-arginine in the molecular weight range of 350 to 50,000 daltons, di-lysine in the molecular weight range of 290 to 15,000 daltons, tri-lysine in the molecular weight range of 290 to 15,000 daltons, poly-lysine in the molecular weight range of 290 to 15,000 daltons, diethylamine and triethanolamine;

    d) from about 0.9 to about 16% of a disintegrant selected from the group consisting of starch, modified starches, microcrystalline cellulose and propylene glycol alginate;

    e) from about 0.3 to about 15.0% of an adhesive polymer selected from the group consisting of hydroxypropyl cellulose, polyvinylpyrrolidone, cellulose acetate phthalate, methyl cellulose and propylene glycol alginate; and

    f) from about 7.0 to about 15% of an non-porous, gastric acid-resistant and pharmaceutically acceptable polymer-coating which contains from about 0.2 to about 2% talc and which is insoluble in the pH range of from about 1.5 to about 5 but is soluble in the pH range of from about 5.5 to about 9.
