CENESTIN vs ESTROVIS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Estrogen replacement therapy; binds to estrogen receptors, activating gene transcription and exerting effects on reproductive tissues, bone, cardiovascular system, and CNS.
Estrovis (estropipate) acts by binding to estrogen receptors (ERα and ERβ), leading to activation of estrogen-responsive genes. It increases hepatic synthesis of sex hormone-binding globulin (SHBG), thyroid-binding globulin (TBG), and other serum proteins, and suppresses gonadotropin secretion via negative feedback on the hypothalamic-pituitary axis.
0.45 mg orally once daily; titrate up to 1.25 mg once daily based on symptoms. Maximum dose 1.25 mg/day.
1 mg orally once daily, continuous dosing cycle (no placebo week).

Terminal elimination half-life is approximately 10-24 hours for conjugated estrogens; this long half-life allows for once-daily dosing and sustained estrogenic effects.
Terminal elimination half-life: 12-18 hours (mean 15 hours). Clinical context: Supports once-daily dosing; steady-state achieved within 3-5 days.
Primarily renal, with approximately 90% excreted in urine as glucuronide and sulfate conjugates; about 10% excreted in feces via bile.
Renal: 60-70% as glucuronide and sulfate conjugates; Fecal/biliary: 20-30% as conjugated metabolites.
