Timing of levothyroxine administration affects serum thyrotropin concentration.
CONTEXT Patients treated with levothyroxine typically ingest it in a fasting state to prevent food impairing its absorption. The serum thyrotropin concentration is the therapeutic index of levothyroxine action. OBJECTIVE The study objective was to determine the effect of the timing of levothyroxine administration in relationship to food on serum thyrotropin levels. DESIGN Participants were ...

in the serum concentration of thyroxine (T4) and triiodothyronine (T3) and a significant increase in serum concentration of thyrotropin (TSH). During the control period (phase I), serum concentrations of T4 averaged 6.9±1.8 ug/100 ml (mean ±SD), T3 106±15 ng/ 100 ml, and TSH 3.7±1.3 tU/lml. During the administration of 1 drop of SSKI twice daily for 11 days (phase II), there was a small but sig...
متن کاملSERUM 6-hCG CONCENTRATION CHANGES FOLLOWING INTRAMUSCULAR hCG ADMINISTRATION
In circumstances such as in vitro fertilization (IVF) or in patients with luteal phase defect, one needs to ensure the establishment of pregnancy as soon as possible. At the same time, a question arises: How can a physician make sure that the β-hCG is of an endogenous source and not the residue of the prescribed drugs (hCG)? In this article we have studied the elimination time of 1M inject...

OBJECTIVE To determine the effects of levothyroxine sodium (L-T4) on serum concentrations of thyroid gland hormones and responses to injections of thyrotropin-releasing hormone (TRH) in euthyroid horses. ANIMALS 12 healthy adult mares. PROCEDURE 8 horses received an incrementally increasing dosage of L-T4 (24, 48, 72, or 96 mg of L-T4/d) for weeks 1 to 8. Each dose was provided for 2 weeks....
