Anastrozole is used in the treatment and prevention of breast cancer in women. Anastrozole and Tamoxifen Alone or in Combination (ATAC) trial was of localized breast cancer and women received either anastrozole, the selective estrogen receptor modulator tamoxifen, or both for five years, followed by five years of follow-up. After more than 5 years the group that received anastrozole had better results than the tamoxifen group. The trial suggested that anastrozole is the preferred medical therapy for postmenopausal women with localized estrogen receptor-positive breast cancer.

The frequency of occurrence was calculated from the number of adverse events observed in the III phase of the study in 9366 postmenopausal women with operable breast cancer treated for 5 years, while the frequency of adverse events in the comparison groups and the opinion of the researcher regarding the dependence of the adverse event on the subject drug not considered.
Determination of the frequency of adverse reactions: very often (more than or equal to 10%); often (from 1 to less than 10%); infrequently (from 0.1 to less than 1%); rarely (from 0.01 to less than 0.1%); very rarely (less than 0.01%)
Musculoskeletal and connective tissue: very often – arthralgia / stiffness of joints, arthritis, often – bone pain, myalgia, infrequently – trigger finger.
Genitals and mammary gland: often – dryness of the vaginal mucosa; vaginal bleeding (mainly during the first weeks after cancellation or change of previous hormone therapy to Arimidex®).
Skin and subcutaneous tissues: very often – a skin rash, often – thinning of the hair (alopecia), allergic reactions, rarely – urticaria, rarely – erythema multiforme, anaphylactoid reaction, skin vasculitis (including some cases of purpura (Shenlein-Genoch syndrome)) , very rarely – Stevens-Johnson syndrome, angioedema.
Gastrointestinal tract: very often – nausea, often – diarrhea, vomiting.
Liver and biliary tract: often – increased activity of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, infrequently – increased activity of gamma-glutamyl transferase and bilirubin concentration, hepatitis.
Nervous system: very often – headache, often drowsiness, carpal tunnel syndrome (mainly observed in patients with risk factors for this disease), sensitivity disorders (including paresthesia, loss or distortion of taste sensations).
Metabolism and nutrition: often – anorexia, hypercholesterolemia, infrequently – hypercalcemia (with / without increasing the concentration of parathyroid hormone). Taking the drug may cause a decrease in bone mineral density due to a decrease in the concentration of circulating estradiol, thereby increasing the risk of osteoporosis and bone fractures.
General disorders: very often – asthenia of mild or moderate severity.
