This invention relates to a chewable lanthanum formulation comprising a pharmaceutically effective amount of a lanthanum compound; and at least one chewable pharmaceutically acceptable excipient. This invention also relates to a pharmaceutical formulation in a tablet or in a powder comprising a pharmaceutically effective amount of a lanthanum compound produced by a process which comprises the steps of: a) powder blending the lanthanum compound and at least one pharmaceutically acceptable excipient in a mixer to form a mixture; or b) powder blending the lanthanum compound and excipients, compressing the resulting combination into a slug material or roller compacting the resulting combination into a strand material, and milling the prepared material into a free flowing mixture; and c) compressing the resulting mixture into a tablet or filing up the resulting mixture in a appropriate container.
A lanthanum carbonate pharmaceutical formulation in a chewable tablet, comprising lanthanum carbonate in an amount of from about 200 mg to about 1000 mg elemental lanthanum in the proportion of about 10 to about 40 wt % of the formulation as elemental lanthanum and pharmaceutically acceptable excipients comprising a diluent in an amount from about 40 to about 80 wt % of the formulation and a flow agent in an amount from about 0.1 to about 5.0 wt % of the formulation, produced by a process which comprises the steps of:
