LEVOLET vs TRIOSTAT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Levolet (levothyroxine) is a synthetic thyroid hormone that replaces endogenous thyroxine (T4). It is converted to triiodothyronine (T3) in peripheral tissues, which binds to thyroid hormone receptors to regulate gene expression, increasing metabolic rate and protein synthesis.
TRIOSTAT (liothyronine sodium) is a synthetic form of the thyroid hormone triiodothyronine (T3). It binds to thyroid hormone receptors in the nucleus, altering gene expression and increasing cellular metabolism, oxygen consumption, and heat production.
Levofloxacin 500 mg orally or intravenously once daily for 5-14 days depending on indication.
Adult: 5 mcg/kg IV every 8 hours. Adjust based on clinical response.

Terminal elimination half-life: 6-8 hours; shorter in patients with hepatic impairment.
2.5 days (terminal); shortened in hyperthyroidism, prolonged in hypothyroidism
Renal: 70-80% unchanged, biliary/fecal: 20-30% as metabolites.
Renal (40% unchanged, 20% as liothyronine conjugates); fecal (35%)
