Moderate

Anastrozole (applies to Arimidex) cholesterol

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Hyperlipidemia

During a clinical trial, more patients receiving anastrozole were reported to have elevated serum cholesterol compared to patients receiving tamoxifen (9% versus 3.5%, respectively). Caution should be taken when this agent is prescribed to these patients.

Moderate

Anastrozole (applies to Arimidex) hepatic dysfunction

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Liver Disease

Anastrozole is extensively metabolized by the liver. Analysis of the pharmacokinetic disposition of anastrozole in patients with hepatic cirrhosis indicates that dosage adjustments of anastrozole are not necessary in patients with mild to moderate hepatic impairment. Clinical monitoring for toxicity associated with anastrozole therapy is recommended. Therapy with anastrozole should be administered cautiously in patients with severe hepatic impairment.

Moderate

Anastrozole (applies to Arimidex) osteoporosis

Moderate Potential Hazard, Moderate plausibility.

Results from the clinical trial bone substudy at 12 and 24 months demonstrated that patients receiving anastrozole had a mean decrease in both lumbar spine and total hip bone mineral density (BMD) compared to baseline. Caution should exercise when prescribing this agent to patients with a risk of fractures, such as the elderly and patients with osteoporosis. Consider bone mineral density monitoring in patients treated with anastrozole.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
