Generic Bicalutamide Information

Introduction

Bicalutamide is an oral anti‑androgen medication used primarily in the management of prostate cancer. In Hong Kong it is prescribed as part of hormone‑blocking therapy for advanced or locally advanced disease, often in combination with a luteinising‑hormone‑releasing hormone (LHRH) agonist. The active compound, bicalutamide, belongs to the “Men’s Health” and “Cancer” therapeutic groups. Although its principal indication is prostate cancer, the drug is occasionally employed off‑label for conditions such as hirsutism or androgen‑dependent skin disorders. Access to the medication may be limited in some local pharmacies, making a reliable online source valuable for patients who require timely treatment.

What is Bicalutamide?

Bicalutamide is a non‑steroidal anti‑androgen (NSAA) that competitively inhibits androgen receptors in target tissues. It was originally developed and marketed by AstraZeneca under the brand name Casodex. Bicalutamide is the generic version of Casodex, containing the same active compound and meeting the same regulatory standards for purity and potency. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, offering the same clinical benefits at a fraction of the brand‑name price.

The medication is supplied as film‑coated tablets of 50 mg strength, intended for once‑daily oral administration. It is approved by the Hong Kong Department of Health and listed on the Hospital Authority formulary for androgen‑suppression therapy in prostate cancer.

How Bicalutamide Works

Bicalutamide exerts its effect by binding to androgen receptors located in prostate cells, as well as in skin, hair follicles, and other androgen‑responsive tissues. By occupying the receptor binding site, it prevents endogenous testosterone and dihydrotestosterone (DHT) from activating the receptor. This blockade reduces the transcription of genes that drive prostate cancer cell growth and survival.

Because bicalutamide does not lower circulating testosterone levels, it is classified as a “pure” anti‑androgen. When combined with an LHRH agonist (e.g., leuprorelin) that suppresses testicular testosterone production, the regimen achieves maximal androgen deprivation—both systemic and at the receptor level. Clinical studies show that maximal androgen blockade (MAB) can delay disease progression and improve overall survival in men with metastatic hormone‑sensitive prostate cancer.

Pharmacokinetically, bicalutamide is absorbed rapidly from the gastrointestinal tract, reaching peak plasma concentrations within 2–4 hours. It is highly protein‑bound (>96 %) and undergoes hepatic metabolism primarily via CYP3A4 to an active metabolite (hydroxy‑bicalutamide) with similar anti‑androgenic activity. The terminal elimination half‑life is approximately 5–7 days, supporting once‑daily dosing. Steady‑state concentrations are typically achieved after 4 weeks of continuous therapy.

Conditions Treated with Bicalutamide

• Advanced or locally advanced prostate cancer (stage III–IV) – used as part of combined androgen deprivation therapy (ADT) or as monotherapy in patients unsuitable for surgical castration.
• Metastatic hormone‑sensitive prostate cancer – incorporated into maximal androgen blockade regimens to improve survival.
• Castration‑resistant prostate cancer (CRPC) – may be added in selected patients who have progressed on LHRH therapy alone.
• Off‑label: hirsutism and androgenic alopecia in women – occasional use when conventional anti‑androgens are contraindicated; limited data in Asian populations.

In Hong Kong, prostate cancer is the third most common cancer among men, with an incidence of approximately 27 per 100,000 males per year (Hong Kong Cancer Registry, 2022). Early and effective androgen suppression remains a cornerstone of management, and bicalutamide provides a well‑tolerated oral option that can be integrated into existing treatment pathways.

Patient Groups Most Likely to Benefit

• Men with newly diagnosed metastatic prostate cancer who are candidates for maximal androgen blockade.
• Patients receiving LHRH agonist therapy who need additional receptor‑level inhibition to achieve complete androgen suppression.
• Individuals intolerant to surgical castration or who prefer a reversible medical approach; bicalutamide allows maintenance of testosterone levels while blocking its action.
• Elderly patients with comorbidities where oral therapy avoids the risks associated with frequent injections.

Bicalutamide is not appropriate for:

• Women who are pregnant or breastfeeding, due to the risk of fetal androgen disruption.
• Patients with severe hepatic impairment (Child‑Pugh C), as metabolism is markedly reduced.
• Individuals taking strong CYP3A4 inducers (e.g., rifampicin, carbamazepine) without dose adjustment, because drug exposure may fall below therapeutic levels.

Risks, Side Effects, and Interactions

Common

• Hot flashes – flushing and sweating, usually mild to moderate.
• Gastrointestinal discomfort – nausea, abdominal pain, diarrhea in up to 15 % of patients.
• Elevated liver enzymes – transaminase increases seen in routine monitoring.
• Gynecomastia – breast enlargement or tenderness, reported in up to 7 % of males.

Rare

• Severe hepatic injury – rare cases of hepatitis or cholestasis; requires prompt discontinuation.
• Skin reactions – maculopapular rash or pruritus; may progress to severe exfoliative dermatitis in isolated reports.
• Thromboembolic events – isolated reports of deep‑vein thrombosis; incidence remains low but warrants vigilance.

Serious

• Liver failure – fulminant hepatic failure is extremely uncommon but life‑threatening; immediate medical attention required.
• Severe allergic reactions – anaphylaxis with airway compromise, hypotension; emergency care needed.
• Cardiovascular toxicity – rare occurrences of myocardial infarction or stroke, particularly in patients with pre‑existing cardiovascular disease.

Drug–Drug Interactions

• CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin) can raise bicalutamide plasma levels, increasing the risk of hepatotoxicity.
• CYP3A4 inducers (e.g., phenytoin, St. John’s wort) may lower exposure, potentially reducing efficacy.
• Warfarin – bicalutamide may enhance anticoagulant effect; INR should be monitored closely.
• Glucocorticoids – concurrent high‑dose steroids may augment liver enzyme abnormalities.

Patients should disclose all prescription, over‑the‑counter, and herbal products before initiating therapy.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dose for prostate cancer is 50 mg once daily, taken with or without food.
• In combination therapy with an LHRH agonist, the same 50 mg dose is maintained; dose reduction is rarely required unless hepatic dysfunction occurs.
• Missed dose: If a dose is forgotten and less than 12 hours have passed, take it as soon as remembered. If more than 12 hours have elapsed, skip the missed dose and resume the regular schedule. Do not double‑dose.
• Overdose: Acute ingestion of large amounts may cause severe nausea, vomiting, hepatic injury, and prolonged androgen blockade. Immediate medical evaluation is recommended. Management is primarily supportive, including monitoring of liver function tests and symptomatic treatment.
• Food and alcohol: Food does not significantly affect absorption; patients can take the tablet with meals for convenience. Limit excessive alcohol intake, as it may exacerbate liver toxicity.
• Comorbidities: In patients with moderate hepatic impairment (Child‑Pugh B), dosing should be reduced to 25 mg daily and liver function monitored every 2 weeks. Renal impairment does not require dose adjustment because the drug is minimally excreted unchanged in urine.
