Levothyroxine

Synthetic thyroxine (T4); thyroid hormone replacement

Mechanism of Action

Levothyroxine is a synthetic form of thyroxine (T4), the primary secretory product of the thyroid gland. T4 is a prohormone converted in peripheral tissues to the biologically active triiodothyronine (T3) by deiodinase enzymes (DIO1, DIO2). T3 binds to nuclear thyroid hormone receptors (TRα and TRβ), which function as ligand-activated transcription factors regulating genes involved in basal metabolic rate, thermogenesis, cardiac output, lipid metabolism, skeletal growth, and neurodevelopment. Thyroid hormones are critical for normal metabolic homeostasis, and exogenous T4 is used to replace deficient endogenous production.

Testosterone Enanthate: Evidence-Based Research Review

6 min

Testosterone enanthate (TE) is a long-acting esterified formulation of the primary endogenous androgen, testosterone. Since its clinical introduction in the 1950s, it has served as a cornerstone for testosterone replacement therapy (TRT) in male hypogonadism and a reference compound in clinical rese

Raloxifene: Evidence-Based Research Review

6 min

Raloxifene is a second-generation selective estrogen receptor modulator (SERM) of the benzothiophene class. Developed to address the limitations of first-generation SERMs like tamoxifen, raloxifene exhibits distinct tissue-specific effects: it acts as an estrogen receptor (ER) agonist in bone and li
