Anastrozole and Meldonium Interaction

Monitor
Mechanism-based 47% confidence

Anastrozole and Meldonium have an interaction requiring monitoring for interaction with 47% confidence. Both Anastrozole and Meldonium negatively affect lipid profiles. Combined use may significantly worsen HDL/LDL ratios. Include lipid support and get bloodwork mid-cycle. Both compounds affect the heart, so monitoring these systems is recommended.

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.

Meldonium

Metabolic Modulator | Endurance & Cardioprotection

Meldonium exerts its primary pharmacological effect by inhibiting gamma-butyrobetaine hydroxylase (BBOX), the enzyme responsible for the final step in the biosynthesis of L-carnitine from gamma-butyrobetaine (GBB). By competitively blocking this enzyme, meldonium reduces endogenous carnitine production, which in turn lowers intracellular carnitine concentrations over time.
