Unadsorbed levothyroxine pharmaceutical compositions, methods of making and methods of administration
First Claim
1. A stabilized solid pharmaceutical composition comprising a levothyroxine salt and a pharmaceutically acceptable carrier, wherein the pharmaceutical composition is substantially free of adsorbed levothyroxine and at least about 85% of the levothyroxine dissolves in aqueous solution in less than about 20 minutes as determined by a standard dissolution test.

Abstract
The present invention generally relates to stable pharmaceutical compositions, and methods of making and administering such compositions. In one aspect, the invention features stabilized pharmaceutical compositions that include pharmaceutically active ingredients such as levothyroxine (T4) sodium and liothyronine (T3) sodium (thyroid hormone drugs), preferably in an immediate release solid dosage form, wherein the levothyroxine is unadsorbed. also provided are methods for making and using such immediate release and stabilized compositions.
