CENESTIN vs STILBETIN
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.
Diethylstilbestrol (STILBETIN) is a nonsteroidal estrogen that binds to estrogen receptors, activating estrogen-responsive genes, leading to increased synthesis of proteins involved in growth and differentiation of female reproductive tissues.
0.45 mg orally once daily; titrate up to 1.25 mg once daily based on symptoms. Maximum dose 1.25 mg/day.
25 mg orally 3 times daily for 5 days; repeat if necessary after 1 month.

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 is approximately 1-2 hours (range 1-3 h) for estradiol; clinical relevance: requires multiple daily dosing (e.g., 3-4 times/day) for sustained effect.
Primarily renal, with approximately 90% excreted in urine as glucuronide and sulfate conjugates; about 10% excreted in feces via bile.
Primarily renal as glucuronide and sulfate conjugates; approximately 50-80% of a parenteral dose excreted in urine within 24 hours; 10-20% via bile into feces.
