<p>Disclosed are sustained release dosage forms of liothyronine, in combination with normal or sustained release of thyroxine in a molar ratio of about 1 to 50 : 1, especially 5 to 20 : 1, useful in thyroid hormone replacement therapy. Surprisingly, it is found that by incorporating liothyronine and optionally thyroxine into a prolonged action dosage form in the described ratios, that the side effects associated with thyroid hormone replacement therapy are greatly reduced or eliminated. The preparation can be a dosage form containing salts of both thyroxine and liothyronine which release in a sustained manner. The preparations will typically contain 5 to 25 mu g of liothryronine. Also disclosed are processes of manufacturing the pharmaceutical preparations. The compositions are useful in treating disease states such as hypothyroidism, hyperthyroidism (in combination with thyrostatic drugs), so-called "TSH" suppressive therapy, and depression.</p> |
