Claim:
1. A salt formulation comprising: particles comprising one or more therapeutic agents, prophylactic agents, nutraceutical agents, diagnostic agents, or combinations thereof, a matrix formed of inert excipient having the particles dispersed therein, a pH-sensitive polymer coating on the outer surface of, or surrounding, the matrix, wherein the composition, thickness and concentration of the pH sensitive polymer coating is effective to resist permeation of water into the matrix and prevent oxidation of the agents for one hour at 100° C., and provides release of the particles upon exposure to a pH and temperature in the gastrointestinal tract but not at a higher pH, wherein the formulation is stable up to one hour at 100° C., and a coating of one or more salts on the pH-sensitive polymer coating, wherein the coating comprises between about 10 and 80% by weight of one or more salts selected from the group consisting of sodium or potassium chloride, magnesium chloride, potassium iodide, phosphates, and combinations thereof.
