Potential effect of aromatase inhibitor on K and Na???

[Guest guest]

I've just begun a 5-year regimen of anastrozole (Arimidex), an aromatase

inhibitor, to help prevent recurrence of estrogen-positive breast cancer. Since

this drug works by affecting hormones produced by the adrenals, I'm wondering if

there are any potential adverse effects it might be expected to have on someone

with hyperaldosteroniam ?? Could it affect my electrolite balance?

By the way, Dr. Grim, my friends, Drs. Danny and Helen Sun send your their

regard.

Thanks so much for your help.

64-year-old female diagnosed with PHA in May of 2009 after 6 trips to the

emergency room with heart attack-like symptoms, high blood pressure, and low K.

Nodules on both adrenals. Took 50mg spiro for two years before being diagnosed

with breast cancer. Immediately discontinued spiro after BC diagnosis, and now

control BP completely with high K, low Na diet. (Have learned that low Na is as

important--if not more important--than high K in my diet.) Feel well and strong

again after stopping the spiro. (The spiro controlled the BP, but I still had

other symptoms that have stopped since stopping the spiro.) I take no other

drugs except Arimidex. I take a few food supplements, e.g. calcium, Vit D, Aloe.
