OBJECTIVE: To review the literature evaluating the benefit and tolerability of aromatase inhibitors (AIs) in breast cancer risk reduction. DATA SOURCE: A PubMed search (1966-July 2014) was conducted using the key terms breast cancer risk reduction, with anastrozole, exemestane, or letrozole, or aromatase inhibitors.

Exemestane belongs to a group of drugs called aromatase inhibitors. Aromatase inhibitors stop the aromatase enzyme from working. This means there’s less oestrogen in the body to help breast cancer cells to grow. Exemestane is one of three aromatase inhibitors. The other two are anastrozole and letrozole. All three drugs have similar

The steroidal inhibitor exemestane is partially non-cross-resistant with nonsteroidal aromatase inhibitors and is a mild androgen and could prove superior to anastrozole regarding efficacy and toxicity OBJECTIVE: To review the literature evaluating the benefit and tolerability of aromatase inhibitors (AIs) in breast cancer risk reduction.

In some clinical articles it states that Exemestane is an irreversible drug, whereas Anastrozole and Letrozole are reversible, though I can’t find any information on what irreversible really means in … There is also another one Exemestane does the same job but for reasons I'm clueless about seems to be the less popular. Jackie has been on Letrozole for about 4 years now but has always been on the original Femara (you may have to find a way to blackmail your GP for those) Anastrozole is a 1mg tablet daily and Letrozole is 2.5mg Arimidex (chemical name: anastrozole) Aromasin (chemical name: exemestane) Femara (chemical name: letrozole) were shown to be more effective at reducing recurrence risk in postmenopausal women and are now used more often than tamoxifen to treat women who’ve gone through menopause. Anastrozole treatment had no impact on plasma lipid levels, whereas both letrozole and exemestane had an unfavorable effect on plasma lipid levels.

15 In a smaller comparative trial of letrozole and anastrozole in patients with metastatic BC, the rates of AEs, serious AEs, and treatment discontinuations were similar, and no significant safety differences were observed 2020-07-16 The androgenic properties of exemestane make it distinct from the nonsteroidal AIs letrozole and anastrozole. Exemestane is structurally related to androstenedione. The principal metabolite of exemestane, 17‐hydroexemestane (17β‐hydroxy‐6‐methylenandrosta‐1,4‐diene‐3,17‐dione), Hirohashi Y, et al. [A Case of Recurrent Breast Cancer with Drug-Induced Interstitial Pneumonia Triggered by the Switch from an Original to a Generic Aromatase Inhibitor]. The Letrozole, Exemestane and Anastrozole Pharmacodynamics (LEAP) study was conducted in 96 healthy postmenopausal women to assess the pharmacodynamic differences between the three AIs at the 12th and 24th week.

Summary This chapter contains sections titled: Introduction Synthesis of Exemestane Synthesis of Anastrozole Synthesis of Letrozole References Aromatase Inhibitors for Breast Cancer: Exemestane (Aromasin®), Anastrozole (Arimidex®), and Letrozole (Femara®) - The Art of Drug Synthesis - Wiley Online Library Anastrozole,[29] letrozole,[30] and exemestane[31] have all been compared with megestrol acetate, and letrozole has been compared with aminoglutethimide,[29] in multicenter, randomized phase III trials in postmenopausal women with estrogen-receptor-positive or estrogen-receptor-unknown metastatic breast cancer following tamoxifen failure. Anastrozole treatment had no impact on plasma lipid levels, whereas both letrozole and exemestane had an unfavorable effect on plasma lipid levels. In indirect comparisons, anastrozole showed the highest degree of selectivity compared with letrozole and exemestane in terms of a lack of effect on adrenosteroidogenesis. The aromatase inhibitors anastrozole, letrozole, and exemestane are presently being compared with the antiestrogen tamoxifen as first-line treatment for postmenopausal patients with hormone-dependent advanced breast cancer (1– 5) and as adjuvant therapies for patients with early-stage breast cancer (6, 7).
