Tamoxifen and Telmisartan Interaction

Avoid
Mechanism-based 75% confidence

Tamoxifen and Telmisartan have a potentially harmful interaction with 75% confidence. Both Tamoxifen and Telmisartan carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently. These compounds primarily affect different organ systems.

Compound Profiles

Tamoxifen

Selective Estrogen Receptor Modulator | PCT & Breast Cancer Treatment

Tamoxifen competitively binds to estrogen receptors (primarily ERalpha) and exerts tissue-selective effects depending on the local coactivator and corepressor environment. In breast tissue and the hypothalamus, tamoxifen acts as an estrogen antagonist, blocking estradiol-mediated signaling.

Telmisartan

Angiotensin II Receptor Blocker | Cardiac Protection On Cycle

Telmisartan selectively blocks the angiotensin II type 1 (AT1) receptor, preventing angiotensin II from exerting its vasoconstrictive, aldosterone-secreting, and pro-fibrotic effects. By antagonizing AT1, telmisartan lowers systemic vascular resistance and blood pressure while simultaneously reducing pathological cardiac and vascular remodeling.
