Liothyronine sodium 是甲状腺激素，能够结合并激活 β1 甲状腺激素受体。

Liothyronine Sodium is the sodium salt form of liothyronine, a synthetic form of the levorotatory isomer of the naturally occurring thyroid hormone triiodothyronine (T3). Liothyronine sodium binds to nuclear thyroid receptors which then bind to thyroid hormone response elements of target genes. As a result, liothyronine sodium induces gene expression that is required for normal growth and development. Liothyronine sodium is more potent and has a more rapid action than thyroxine (T4).

Liothyronine Sodium的化学性质几乎与三碘甲状腺氨酸一样,作用于甲状腺激素受体α和β-1。作为甲状腺激素的最有效形式,Liothyronine Sodium可使机体基础代谢率增加,影响蛋白合成,并且使机体对儿茶酚胺（如肾上腺素）敏感度增加。
