Aromatase Inhibitor | What you need to know
Table of contents
Aromatase Inhibitors (AIs) are medications designed to lower estrogen levels by blocking the aromatase enzyme. Commonly used for hormone-sensitive conditions like breast cancer, AIs also serve as Estrogen blockers for men on Testosterone Replacement Therapy (TRT) who experience elevated E2 (estradiol) levels.
At H.U.M. Clinic, a leading hormone clinic in Bangkok, we offer expert care and personalized treatments for patients requiring Aromatase Inhibitors. Whether you’re managing high estrogen levels on TRT or addressing hormone imbalances, our clinic in Thailand ensures safe and effective solutions tailored to your needs.
What are Aromatase Inhibitors?
Aromatase inhibitors (AIs), also called Estrogen blockers, are medications that help reduce estrogen levels by blocking the activity of the aromatase enzyme. These drugs are vital in treating hormone-sensitive conditions such as breast cancer and are sometimes used in hormone replacement therapy.
Definition and Role
Estrogen blockers works by stopping the aromatase enzyme from converting androgens into estrogen. This reduction in estrogen levels is particularly useful for treating hormone receptor-positive breast cancer in postmenopausal women. They also play a role in other hormone-sensitive treatments, including managing certain fertility and endocrine disorders.
Mechanism of Action
Aromatase inhibitors (AIs) block estrogen production by targeting aromatase, an enzyme responsible for synthesizing estrogen from androgens. This is especially effective in postmenopausal individuals, where most estrogen comes from peripheral tissues rather than the ovaries. By lowering estrogen, these Estrogen blockers also slow the growth of estrogen-dependent tumors.
Types of Aromatase Inhibitors
Aromatase inhibitors are classified into two main types: nonsteroidal and steroidal inhibitors. Both are effective in reducing estrogen levels, but they differ in their chemical structure and mode of action.
Nonsteroidal Aromatase Inhibitors
Anastrozole and Letrozole fall under this category. These drugs bind reversibly to the aromatase enzyme, temporarily blocking its ability to produce estrogen. They are commonly prescribed for postmenopausal women with hormone receptor-positive breast cancer due to their strong efficacy in lowering estrogen levels.
Steroidal Aromatase Inhibitors
Exemestane is a steroidal aromatase inhibitor that binds irreversibly to the aromatase enzyme, permanently deactivating its function. This medication mimics natural androgen substrates and is often used when resistance to nonsteroidal options develops, offering an alternative approach in managing estrogen-dependent conditions.
Medical Uses of Aromatase Inhibitors
Aromatase inhibitors, aka Estrogen blockers, are versatile medications used in various medical treatments. Their primary use is in hormone-sensitive conditions, with applications in both women and men to address estrogen-related issues.
For Female: the Medical Uses of Aromatase Inhibitors
- Breast Cancer Treatment: This group of medication are essential in treating hormone receptor-positive breast cancer in postmenopausal women. By reducing estrogen levels, these medications slow the growth of estrogen-dependent tumors and reduce recurrence risks.
- Fertility and Endometriosis Management: Off-label, Estrogen blockers are sometimes used for infertility and endometriosis. They help lower estrogen levels, which can reduce endometrial tissue growth and improve ovulation in certain cases.
For male: Medical Uses of Aromatase Inhibitors
- Anabolic Steroid Protocols: In men using multiple anabolic steroids, estrogen blockers act as a maintenance tool to prevent excess estrogen production, which can cause unwanted side effects like gynecomastia.
- TRT and High E2 Levels: Estrogen blockers are also used in men on Testosterone Replacement Therapy (TRT) who experience elevated Estradiol (E2) levels due to the aromatization of Testosterone to Estrogen.
Side Effects and Considerations
While effective, Estrogen blockers may cause side effects. Understanding these potential issues and discussing them with your healthcare provider is crucial for safe use and management.
Common Side Effects
These side effects are typically manageable but should be reported if they persist or worsen. Regular checkups are recommended to address any discomfort early. Patients using Estrogen blockers might experience:
- Hot flashes
- Joint pain
- Fatigue
- Mild nausea
Long-Term Risks
Prolonged use of Estrogen blockers can lead to reduced Estrogen (E2) levels, which is essential for bone health in both females and males. Low estrogen can increase the risk of osteoporosis.
It is vital to maintain the correct balance of E2 through regular testing and consultations with your doctor. Specific dosages and treatment durations should be personalized to ensure the benefits outweigh the risks.

FAQ About Aromatase Inhibitors
Can Aromatase Inhibitors Be Used for Gynecomastia in Men?
Yes, aromatase inhibitors like Anastrozole are sometimes used to treat gynecomastia in men by lowering estrogen levels. However, they are typically prescribed in specific cases where hormone imbalance is the cause.
Are Aromatase Inhibitors Effective for Bodybuilding?
Some bodybuilders use aromatase inhibitors off-label to prevent the conversion of testosterone to estrogen during anabolic steroid cycles. However, misuse can lead to health risks, so it’s crucial to consult a doctor before use.
Do Aromatase Inhibitors Interact with Other Medications?
Yes, aromatase inhibitors can interact with medications such as tamoxifen, hormone therapies, and certain supplements. It’s essential to inform your doctor about all medications and supplements you’re taking.
What Should I Do if I Miss a Dose?
If you miss a dose, take it as soon as you remember. If it’s close to your next scheduled dose, skip the missed one and continue as usual. Do not double the dose to make up for the missed one.
