Abstract: An anti-diarrhea composition comprises diarrhea symptom-reducing amounts of a powdered absorptive material capable of absorbing pathogenic intestinal bacteria, a sodium salt, a potassium salt and a sugar. The absorptive material may be Smectite or mormoiron attapulgite. The salts are preferably NaCl and KCl, with NaHCO.sub.3 also being present. Suitable sugars are glucose and dextrose. The composition may also contain a suspending agent, a coloring agent, a flavoring agent and a sweetening agent. It may be packaged in solid form for admixture with water prior to administration and is preferably moisture protected, for example by the nature of the packaging or by inclusion of a dessicant. The absorptive material may be packaged separately from the salts and sugar. On admixture with water for adminstration, the composition preferably contains, per liter, 2.5 to 15 g of absorptive material, 10 to 30 g of glucose, 60 to 120 mEq of Na.sup.+, 10 to 50 mEq of HCO.sup.- and 10 to 30 mEq of K.sup.+.
