Biological Activity

Anastrozole can be replaced by letrozole any time during endocrine therapy. The patients taking anastrozole plus letrozole surprisingly seemed to have better OS than patients taking anastrozole alone. Exemestane and anastrozole appear to offer benefit for postmenopausal woman at high risk for invasive breast cancer and are well tolerated. When present first-year data from a direct comparison of anastrozole and letrozole for height augmentation in short pubertal boys. Letrozole was more potent in hormonal manipulation than anastrozole. First-year growth velocities were comparable, but improvement in PAH was greater in the anastrozole group.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
