Question 1

What is Flutamide?

Accepted Answer

Flutamide is a type of hormone therapy known as a nonsteroidal antiandrogen. It works by competing with testosterone and other male hormones, called androgens, for binding sites in the body.

By blocking these hormones, the medication helps interfere with the growth and spread of cells that depend on androgens. It is typically used in combination with other treatments to manage hormone-sensitive conditions.

Question 2

Question 3

How does Flutamide work?

Accepted Answer

Mechanism of Action

Flutamide belongs to a class of drugs known as nonsteroidal antiandrogens. It is primarily used to treat prostate cancer, a condition where cancer cells often depend on male hormones (androgens) to multiply and spread.

The medication works through the following processes:

Blocking Hormone Receptors: Flutamide prevents androgens, such as testosterone, from binding to specific receptors on the surface of prostate cancer cells.

Inhibiting Hormone Uptake: It interferes with the ability of cancer cells to take up and use these hormones.

Slowing Cancer Growth: By cutting off the hormonal signals that stimulate the cancer, the drug helps to slow down or stop the growth and spread of the disease.

Because prostate cancer is sensitive to androgens, reducing the influence of these hormones is a common strategy for managing the condition. Flutamide is often used alongside other treatments that lower the overall production of testosterone in the body to provide a more complete blockade of male hormones.

Question 8

What is the dosage of Flutamide and how do I take it?

Accepted Answer

How to Take Flutamide

Flutamide comes as a capsule to be taken by mouth. It is generally taken three times a day, spaced at regular intervals. To help maintain a steady level of the medication in your body, it is important to take it at the same times every day.

This medication can be taken with or without food. Follow the directions on your prescription label carefully and do not take more or less of the medication than prescribed by your healthcare provider.

Missed Dose

If you miss a dose of flutamide, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take extra medicine to make up for a missed dose.

Important Considerations

Flutamide is typically used in combination with other medications, such as luteinizing hormone-releasing hormone (LHRH) agonists. Do not stop taking flutamide or change your dosing schedule without consulting your doctor, even if you feel well, as the treatment is most effective when used consistently as directed.

Question 9

Is Flutamide safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Flutamide is indicated for use only in male patients. It is not for use in women, particularly those who are or may become pregnant. Clinical data and animal studies indicate that flutamide can cause significant harm to a fetus. In animal research, exposure to the medication during pregnancy resulted in developmental issues, including the feminization of male offspring.

Because of these risks, flutamide is contraindicated in pregnancy. Men who are taking flutamide and have partners who can become pregnant should use effective contraception during treatment and for a period of time after the final dose to prevent pregnancy.

Breastfeeding

It is not known whether flutamide or its components pass into human breast milk. Because the drug is not indicated for use in women, there is no established safety information regarding its use while breastfeeding. Individuals should discuss any concerns with their healthcare provider.

Question 10

What forms and strengths does Flutamide come in?

Accepted Answer

Capsule: This medication is taken by mouth, typically several times a day as part of a specific treatment plan directed by a healthcare professional.

Question 11

What is the FDA approval status of Flutamide?

Accepted Answer

FDA Approval and Indications

Flutamide is approved by the U.S. Food and Drug Administration (FDA) for the treatment of metastatic prostatic carcinoma (Stage D2). It is indicated for use in combination with luteinizing hormone-releasing hormone (LHRH) agonists, such as leuprolide acetate.

Boxed Warning

The FDA-approved labeling for flutamide includes a boxed warning concerning the risk of serious liver injury. Post-marketing reports have documented cases of hospitalization, liver failure, and death associated with its use. Hepatic injury may occur at any time during treatment, although it often presents within the first few months of therapy.

Regulatory Requirements and Monitoring

Due to the risk of hepatotoxicity, the FDA requires specific monitoring protocols for patients prescribed flutamide:

Liver Function Testing: Periodic serum transaminase testing is necessary. Testing is recommended before starting treatment, monthly for the first four months, and periodically thereafter.

Symptom Reporting: Patients are advised to seek immediate medical attention if they experience symptoms of liver dysfunction, such as jaundice, dark urine, or persistent right upper quadrant pain.

Discontinuation: Treatment should be discontinued if liver enzyme levels rise significantly (typically two times the upper limit of normal) or if clinical jaundice develops.

Pharmacogenomic Considerations

The FDA identifies flutamide as a drug with pharmacogenomic biomarkers in its labeling. Specifically, caution is advised for individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency. These patients may be at an increased risk of developing hemolytic anemia or methemoglobinemia while taking this medication.

Question 12

What should I know about Flutamide and cost?

Accepted Answer

Factors Influencing Cost

The price of flutamide can vary based on the following factors:

Generic Availability: Flutamide is available as a generic medication. Generic versions are typically less expensive than brand-name drugs while containing the same active ingredients.

Insurance Coverage: Many health insurance plans and Medicare Part D cover flutamide. The actual out-of-pocket cost will depend on the specific plan's deductible, copayment, or coinsurance requirements.

Pharmacy Choice: Prices for prescription medications can differ between retail pharmacies. Some patients may find lower prices through mail-order services or by using pharmacy discount programs.

Because flutamide is a prescription-only medication, it must be ordered by a healthcare provider. Patients are encouraged to check with their insurance provider or local pharmacist to determine the exact cost under their specific plan.
