How it works
Exemestane lowers estrogen levels by permanently blocking the aromatase enzyme. With estradiol levels reduced, estrogen-dependent breast cancer cells lose one of the signals they rely on to grow, which helps slow the disease.
Uses
Doctors prescribe exemestane to postmenopausal women with hormone-receptor-positive breast cancer, often after they’ve already spent a couple of years on tamoxifen. It’s also used in cases of advanced disease when previous antiestrogen treatments are no longer working.
Who shouldn’t take it
Anyone with a known allergy to the drug or its ingredients should avoid it. It isn’t meant for premenopausal women or anyone using estrogen-based therapies. People with serious liver problems also shouldn’t use this medication.
Important considerations
Because exemestane reduces estrogen, it can affect bone strength. People with osteoporosis—or at higher risk for it—may need regular bone-density checks. It should not be taken during pregnancy or while breastfeeding.
Interactions
Some medicines that affect the CYP450 enzyme system can change how exemestane behaves in the body. This includes certain antifungals, anticonvulsants, and medications for HIV. It’s important to let a healthcare professional know about all drugs, supplements, and herbal products being used.
