This medicine is used to treat prostate cancer in men. It works by blocking the action of male hormones, which can help slow down the growth of the cancer. This medication is not for use in women.
Indications
Bicalutamide is indicated for use in combination therapy with a luteinizing hormone-releasing hormone (LHRH) analog for the treatment of Stage D2 metastatic carcinoma of the prostate.
Pharmacology
Bicalutamide is a non-steroidal androgen receptor inhibitor. It competitively inhibits the action of androgens by binding to cytosol androgen receptors in the target tissue. Prostatic carcinoma is known to be androgen sensitive and responds to treatment that counteracts the effect of androgen and/or removes the source of androgen.
Dosage & Administration
Important: Do not take any medication without a doctor's prescription. Self-medication can be dangerous.
The recommended dose for Bicalutamide therapy in combination with an LHRH analog is one 50 mg tablet once daily (morning or evening), with or without food.
Pediatric Use: The safety and effectiveness of Bicalutamide in pediatric patients have not been established.
Hepatic Impairment: Bicalutamide is extensively metabolized by the liver. It should be used with caution in patients with moderate-to-severe hepatic impairment.
Interaction
R-bicalutamide is an inhibitor of CYP 3A4; therefore, caution should be used when Bicalutamide is co-administered with CYP 3A4 substrates
PT/INR should be closely monitored in patients already receiving coumarin anticoagulants who are started on Bicalutamide
Contraindications
Bicalutamide is contraindicated in any patient who has shown a hypersensitivity reaction to the drug or any of the tablet’s components. Bicalutamide has no indication for women, and should not be used in this population.
Side Effects
Adverse reactions that occurred in more than 10% of patients receiving Bicalutamide plus an LHRH-A were: hot flashes, pain (including general, back, pelvic and abdominal), asthenia, constipation, infection, nausea, peripheral edema, dyspnea, diarrhea, hematuria, nocturia, and anemia.
Pregnancy & Lactation
Bicalutamide is contraindicated for use in pregnant women because it can cause fetal harm. Bicalutamide is not indicated for use in females. There are no human data on the use of Bicalutamide in pregnant women.
Precautions & Warnings
Hemorrhage with concomitant use of Coumarin Anticoagulant. Closely monitor the Prothrombin Time (PT) and International Normalized Ratio (INR), and adjust the anticoagulant dose as needed
Gynecomastia and breast pain have been reported during treatment with Bicalutamide 150 mg when used as a single agent as it cause a reduction in glucose tolerance in males
Consideration should be given to monitoring blood glucose in patients receiving Bicalutamide in combination with LHRH agonists
Monitoring Prostate Specific Antigen (PSA) is recommended. Evaluate for clinical progression if PSA increases
Use in Special Populations
Pediatric Use: The safety and effectiveness of Bicalutamide in pediatric patients have not been established.
Hepatic Impairment: Periodic liver function tests should be considered for hepatic-impaired patients on long-term therapy.
Renal Impairment: Renal impairment (as measured by creatinine clearance) had no significant effect on the elimination of total bicalutamide or the active R-enantiomer.
Overdose Effects
Long-term clinical trials have been conducted with dosages up to 200 mg of Bicalutamide daily and these dosages have been well tolerated. A single dose of Bicalutamide that results in symptoms of an overdose considered to be life threatening has not been established. There is no specific antidote; treatment of an overdose should be symptomatic.
Storage Conditions
Store at temperature not exceeding 30°C in a dry place. Protect from light and moisture.
