Exemestane and Raloxifene Interaction

Avoid
Mechanism-based 75% confidence

Exemestane and Raloxifene have a potentially harmful interaction with 75% confidence. Both Exemestane and Raloxifene carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently. Both compounds affect the gonads and pituitary, so monitoring these systems is recommended.

Compound Profiles

Exemestane

Steroidal Aromatase Inhibitor | Irreversible Estrogen Control

Exemestane functions as a mechanism-based (suicide) inhibitor of aromatase (cytochrome P450 19A1). Due to its steroidal structure, exemestane is recognized by aromatase as a substrate analogue and enters the enzyme's active site.

Raloxifene

Selective Estrogen Receptor Modulator | Gynecomastia & Bone Health

Raloxifene binds to both estrogen receptor alpha (ERalpha) and estrogen receptor beta (ERbeta), producing tissue-dependent agonist or antagonist effects determined by the local complement of coactivator and corepressor proteins. In breast tissue, raloxifene functions as a potent estrogen antagonist, blocking estradiol-mediated proliferative signaling with high selectivity.
