CENESTIN vs ESTROGENIC SUBSTANCE
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.
Estrogens bind to and activate nuclear estrogen receptors (ERα and ERβ), leading to gene transcription and regulation of reproductive tissues and secondary sexual characteristics.
0.45 mg orally once daily; titrate up to 1.25 mg once daily based on symptoms. Maximum dose 1.25 mg/day.
0.3 to 1.25 mg orally once daily; 25 to 100 mcg transdermal patch applied twice weekly; 0.5 to 2 mg vaginal cream daily for 3 weeks then 1 week off.

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 13-27 hours for endogenous estrogens, with clinically therapeutically relevant metabolites having half-lives up to 24-36 hours, allowing once-daily dosing.
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 60-80% excreted in urine, 10-30% in feces via biliary elimination.
