side effects of liothyronine sodium
Since Liothyronine sodium (T3) is not firmly bound to serum protein, it is readily available to body tissues. Liothyronine sodium has a rapid cutoff of activity which permits quick dosage adjustment and facilitates control of the effects of overdosage, should they occur. The higher affinity of levothyroxine (T 4) as compared to triiodothyronine (T 3) for both thyroid-binding globulin and thyroid-binding prealbumin partially explains the higher serum levels and longer half-life of the former hormone.
