Selective non-steroidal aromatase inhibitor: blocks aromatase conversion of adrenal androgens (androstenedione, testosterone) to estrone and estradiol, lowering serum estradiol; no detectable effect on formation of adrenal corticosteroids or aldosterone (ARIMIDEX label §12.1).
Pregnant owners should avoid handling agent (Carpenter's Exotic Animal Formulary 6th ed, Table 11.8). Human label: can cause fetal harm when administered to a pregnant woman (ARIMIDEX §5.4); contraindicated with hypersensitivity to the drug or excipients (§4); do not combine with tamoxifen; estrogen-containing products may diminish its activity (§7).
Species-specific contraindications and adverse-reaction reports for ferrets may differ from canine / feline reference data — consult the primary citations listed with each rule.

Why a species-specific page? Anastrozole pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in ferrets — the rules above are the citations specific to this species, not generic recommendations.
