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 (3,3',5-Triiodo-L-thyronine 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).

| Description | 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 (3,3',5-Triiodo-L-thyronine 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).  | 
| In vivo | The chemical properties of Liothyronine Sodium are nearly identical to those of Triiodothyronine, acting on thyroid hormone receptors alpha and beta-1. As the most potent form of thyroid hormone, Liothyronine Sodium can increase the basal metabolic rate, affect protein synthesis, and enhance the body's sensitivity to catecholamines (such as adrenaline).  |
