Anastrozole is indicated for the first-line treatment of postmenopausal woman with hormone receptor positive or hormone receptor unknown locally advanced or metastatic breast cancer. It is also indicated for treatment of advanced breast cancer in postmenopausal women with disease progression following tamoxifen therapy. /Included in US product label/

Anastrozole is an option for the neoadjuvant treatment of hormone receptorpositive, locally advanced breast cancer in postmenopausal women. Two phase 2, randomized, double-blind clinical trials found anastrozole to be at least as effective as tamoxifen in response rates and rates of improved surgery. A phase 2, unpublished abstract reported no differences between neoadjuvant anastrozole and chemotherapy (doxorubicin and paclitaxel) in response rates, number of patients qualifying for breast-conserving surgery, and 3-year disease-free survival. An international expert panel recommends neoadjuvant endocrine therapy in postmenopausal women who would benefit from preoperative chemotherapy but are ineligible to receive it. Anastrozole was well-tolerated. /Not included in US product label/

Among patients receiving adjuvant therapy, venous thromboembolic events occurred less frequently in patients receiving anastrozole than in those receiving tamoxifen (2 versus 4%); this included deep venous thrombosis (1 versus 2%). Ischemic cerebrovascular events also occurred less frequently in patients receiving anastrozole compared with those receiving tamoxifen (1 versus 2%). Ischemic cardiovascular disease was reported in 3% of such patients receiving anastrozole. Although angina pectoris was reported more frequently in patients receiving adjuvant therapy with anastrozole than in those receiving tamoxifen (about 2 versus 1%), the incidence of myocardial infarction was similar (0.8%).
McEvoy, G.K. (ed.). American Hospital Formulary Service. AHFS Drug Information. American Society of Health-System Pharmacists, Bethesda, MD. 2006., p. 927
Among patients receiving anastrozole as first-line therapy, thromboembolic disease was reported in 18 patients (4%), with 5 patients experiencing venous thrombosis (including pulmonary embolus, thrombophlebitis, and retinal vein thrombosis) and 13 patients experiencing coronary and/or cerebral thrombosis (including myocardial infarction, myocardial ischemia, angina pectoris, cerebrovascular accident, cerebral ischemia, and cerebral infarct). Despite its lack of estrogenic activity, there was no evidence of an increased incidence of myocardial infarction in patients receiving anastrozole compared with those receiving tamoxifen.

Anastrozole is indicated as adjunct therapy in the treatment of hormone receptor-positive early breast cancer in postmenopausal women, and as a first-line treatment for hormone receptor-positive (or hormone receptor-unknown) locally advanced or metastatic breast cancer in postmenopausal women. It may also be used in the treatment of advanced breast cancer in postmenopausal women who experience disease progression despite treatment with [tamoxifen].
Gynaecomastia, McCune-Albright syndrome, Short stature due to Growth Hormone deficiency, Testotoxicosis
Anastrozole prevents the conversion of adrenal androgens (e.g. [testosterone]) to estrogen in peripheral and tumour tissues. As the growth of many breast cancers is stimulated and/or maintained by the presence of estrogen, anastrozole helps to treat these cancers by decreasing the levels of circulating estrogens. Anastrozole has a relatively long duration of action allowing for once daily dosing - serum estradiol is reduced by approximately 70% within 24 hours of beginning therapy with 1mg once daily, and levels remain suppressed for up to 6 days following cessation of therapy. The incidence of ischemic cardiovascular events was increased during anastrozole therapy and patients with pre-existing ischemic heart disease should consider the risks and benefits of anastrozole before beginning therapy. Anastrozole has also been reported to decrease spine and hip bone mineral density (BMD), so consideration should be given to monitoring of BMD in patients receiving long-term therapy.
Antineoplastic Agents, Hormonal
Antineoplastic agents that are used to treat hormone-sensitive tumors. Hormone-sensitive tumors may be hormone-dependent, hormone-responsive, or both. A hormone-dependent tumor regresses on removal of the hormonal stimulus, by surgery or pharmacological block. Hormone-responsive tumors may regress when pharmacologic amounts of hormones are administered regardless of whether previous signs of hormone sensitivity were observed. The major hormone-responsive cancers include carcinomas of the breast, prostate, and endometrium; lymphomas; and certain leukemias.

Absorption
Anastrozole is rapidly absorbed and Tmax is typically reached within 2 hours of dosing under fasted conditions. Coadministration with food reduces the rate but not the overall extent of absorption - mean Cmax decreased by 16% and the median Tmax was extended to 5 hours when anastrozole was administered 30 minutes after ingestion of food, though this relatively minor alteration in absorption kinetics is not expected to result in clinically significant effects.
Route of Elimination
Hepatic metabolism accounts for approximately 85% of anastrozole elimination. Approximately 10% of the administered dosage is eliminated unchanged in the urine.
Volume of Distribution
The volume of distribution of anastrozole into brain tissue in mice is 3.19 mL/g. Distribution into the CNS is limited due to the activity of P-gp efflux pumps at the blood brain barrier, of which anastrozole is a substrate.
Clearance
Anastrozole's clearance is mainly via hepatic metabolism and can therefore be altered in patients with hepatic impairment - patients with stable hepatic cirrhosis exhibit an apparent oral clearance approximately 30% lower compared with patients with normal liver function. Conversely, renal impairment has a negligible effect on total drug clearance as the renal route is a relatively minor clearance pathway for anastrozole. In volunteers with severe renal impairment, renal clearance was reduced by 50% while total clearance was only reduced by approximately 10%.
Anastrozole is well absorbed into systemic circulation following oral administration. Plasma concentrations approach steady-state at about 7 days of once-daily dosing, and steady-state concentrations are approximately 3-4 times higher than concentrations achieved after a single dose of the drug. Food does not affect the extent of oral absorption of anastrozole.

Anastrozole is primarily metabolized in the liver via oxidation and glucuronidation to a number of inactive metabolites, including hydroxyanastrozole (both free and glucuronidated) and anastrozole glucuronide. Oxidation to hydroxyanastrozole is catalyzed predominantly by CYP3A4 (as well as CYP3A5 and CYP2C8, to a lesser extent) and the direct glucuronidation of anastrozole appears to be catalyzed mainly by UGT1A4. Anastrozole may also undergo N-dealkylation to form triazole and 3,5-Bis-(2-methylpropiononitrile)-benzoic acid. Labels for anastrozole state the main metabolite found in plasma following administration is triazole, but a recent pharmacokinetic study was unable to detect any products of N-dealkylation _in vitro_.
Anastrozole is extensively metabolized in the liver. Metabolism of anastrozole occurs via N-dealkylation, hydroxylation, and glucuronidation. Three metabolites of anastrozole have been identified in human plasma and urine: triazole, a glucuronide conjugate of anastrozole, and a glucuronide conjugate of hydroxyanastrozole. Triazole, the major circulating metabolite of anastrozole, lacks pharmacologic activity, and the aromatase inhibiting activity of anastrozole results principally from the parent drug. In addition, there are several minor metabolites of anastrozole, accounting for less than 5% of an administered dose, which have not been identified.
McEvoy, G.K. (ed.). American Hospital Formulary Service. AHFS Drug Information. American Society of Health-System Pharmacists, Bethesda, MD. 2006., p. 929
The elimination half-life of anastrozole is approximately 50 hours.
Following oral administration of anastrozole in postmenopausal women, a mean terminal elimination half-life of approximately 50 hours has been reported.
McEvoy, G.K. (ed.). American Hospital Formulary Service. AHFS Drug Information. American Society of Health-System Pharmacists, Bethesda, MD. 2006., p. 930
Anastrazole exerts its anti-estrogenic effects via selective and competitive inhibition of the aromatase enzyme found predominantly in the adrenal glands, liver, and fatty tissues. Many breast cancers are hormone receptor-positive, meaning their growth is stimulated and/or maintained by the presence of hormones such as estrogen or progesterone. In postmenopausal women, estrogen is primarily derived from the conversion of adrenally-produced androgens into estrogens by the aromatase enzyme - by competitively inhibiting the biosynthesis of estrogen at these enzymes, anastrozole effectively suppresses circulating estrogen levels and, subsequently, the growth of hormone receptor-positive tumours.
Anastrozole is a nonsteroidal aromatase inhibitor that interferes with estradiol production in peripheral tissues. Adrenally generated androstenedione, the chief source of circulating estrogen in postmenopausal women, is converted by aromatase to estrone, which is further converted to estradiol. Growth of many breast cancer tumors containing estrogen receptors and aromatase can be promoted by estrogen.
Thomson/Micromedex. Drug Information for the Health Care Professional. Volume 1, Greenwood Village, CO. 2006., p. 151
Anastrozole is a potent and selective non-steroidal aromatase inhibitor. It significantly lowers serum estradiol concentrations and has no detectable effect on formation of adrenal corticosteroids or aldosterone.
Physicians Desk Reference 60th ed, Thomson PDR, Montvale, NJ 2006., p. 666
Because estrogen acts as a growth factor for hormone-dependent breast cancer cells, anastrozole-induced reduction of serum and tumor concentrations of estrogen inhibits tumor growth and delays disease progression. Anastrozole selectively inhibits the conversion of androgens to estrogens. In postmenopausal women, ovarian secretion of estrogen declines and conversion of adrenal androgens (mainly androstenedione and testosterone) to estrone and estradiol in peripheral tissues (adipose, muscle, and liver), catalyzed by the aromatase enzyme, is the principal source of estrogens. Anastrozole inhibits the aromatase enzyme by competitively binding to the heme of the cytochrome P-450 unit of the enzyme; suppression of estrogen biosynthesis in all tissues reduces serum concentrations of circulating estrogens, including estrone, estradiol, and estrone sulfate. Anastrozole selectively inhibits synthesis of estrogens and does not affect synthesis of adrenal corticosteroid, aldosterone, or thyroid hormone. In animals, anastrozole has not been shown to possess direct progestogenic, androgenic, or estrogenic activity, but alterations in the circulating concentrations of progesterone, androgens, and estrogens have been observed.
