Absorption and Distribution: Letrozole is rapidly and completely absorbed from the gastrointestinal tract and absorption is not affected by food. It is metabolized slowly to an inactive metabolite whose glucuronide conjugate is excreted renally, representing the major clearance pathway. About 90% of radiolabeled letrozole is recovered in urine. Letrozole’s terminal elimination half-life is about 2 days and steady-state plasma concentration after daily 2.5 mg dosing is reached in 2 to 6 weeks. Pl...

14.1 Updated Adjuvant Treatment of Early Breast Cancer In a multicenter study (BIG 1-98, NCT00004205) enrolling over 8,000 postmenopausal women with resected, receptor-positive early breast cancer, one of the following treatments was randomized in a double-blind manner: Option 1: tamoxifen for 5 years Letrozole for 5 years tamoxifen for 2 years followed by letrozole for 3 years Letrozole for 2 years followed by tamoxifen for 3 years Option 2: tamoxifen for 5 years Letrozole for 5 years The study in the adjuvant setting, BIG 1-98 was designed to answer two primary questions: whether letrozole f...

Decreases in bone mineral density may occur. Consider bone mineral density monitoring ( 5.1 ) Increases in total cholesterol may occur. Consider cholesterol monitoring. ( 5.2 ) Fatigue, dizziness and somnolence may occur. Exercise caution when operating machinery ( 5.4 ) Embryo-Fetal toxicity: Can cause fetal harm when administered to pregnant women. Obtain a pregnancy test in females of reproductive potential. Advise females of reproductive potential to use effective contraception ( 5.6 , 8.1 ,...

7 DRUG INTERACTIONS Tamoxifen Coadministration of letrozole and tamoxifen 20 mg daily resulted in a reduction of letrozole plasma levels of 38% on average (study P015). Clinical experience in the second-line breast cancer trials (AR/BC2 and AR/BC3) indicates that the therapeutic effect of letrozole therapy is not impaired if letrozole is administered immediately after tamoxifen. Cimetidine A pharm...
