Anastrozole and Rapamycin Interaction

Monitor
Mechanism-based 55% confidence

Anastrozole and Rapamycin have an interaction requiring monitoring for interaction with 55% confidence. Both Anastrozole and Rapamycin negatively affect lipid profiles. Combined use may significantly worsen HDL/LDL ratios. Include lipid support and get bloodwork mid-cycle. These compounds primarily affect different organ systems.

Compound Profiles

Anastrozole

Aromatase Inhibitor | Estrogen Management

Anastrozole competitively binds to the heme group of the aromatase enzyme (cytochrome P450 19A1), reversibly inhibiting its catalytic activity. Aromatase is responsible for the final step in estrogen biosynthesis, converting testosterone to estradiol and androstenedione to estrone in peripheral tissues including adipose, muscle, liver, and brain.

Half-life: ~40-50 hours Typical dose: 0.25-0.5mg EOD or E3D (estrogen management) pct, anabolic

Rapamycin

mTOR Inhibitor | Longevity & Immunosuppression

Rapamycin exerts its effects by binding to the intracellular protein FKBP12, forming a complex that directly and specifically inhibits mechanistic target of rapamycin complex 1 (mTORC1). mTORC1 is a master nutrient-sensing kinase that integrates signals from growth factors, amino acids, energy status, and stress to regulate cell growth, proliferation, and metabolism.
