Generic Casodex Information

Introduction

Casodex (bicalutamide) is an oral anti‑androgen medication approved for the treatment of prostate cancer in adult men. It belongs to the therapeutic groups of men’s health and oncology. In the United Kingdom the product is marketed by AstraZeneca and is widely prescribed as part of combined androgen blockade, either alone or together with luteinising‑hormone‑releasing hormone (LHRH) analogues. Prostate cancer remains the second most common malignancy in UK men, accounting for roughly 45 000 new diagnoses each year, which makes effective anti‑androgen therapy a cornerstone of modern urological practice.

What is Casodex?

Casodex is a synthetic, non‑steroidal androgen receptor antagonist. The active ingredient is bicalutamide, a selective blocker of the androgen receptor (AR) that prevents testosterone and dihydrotestosterone from stimulating prostate cancer cells. Casodex is supplied as 50 mg film‑coated tablets for oral administration.

The drug was first developed in the 199s by AstraZeneca and received Marketing Authorisation in the UK in 1995. It is listed in the British National Formulary (BNF) under the name “bicalutamide 50 mg tablets.” While Casodex is the original brand name, the same active compound is also available from other manufacturers as generic bicalutamide, providing a lower‑cost alternative with identical therapeutic properties.

How Casodex Works

Bicalutamide binds competitively to the intracellular androgen receptor with an affinity several hundred times greater than that of endogenous androgens. Once bound, the drug‑receptor complex cannot translocate to the nucleus, thereby blocking transcription of androgen‑responsive genes that drive proliferation and survival of prostate cancer cells.

Because Casodex does not reduce circulating testosterone levels, it avoids the acute surge of luteinising hormone that can occur with surgical or chemical castration. The therapeutic effect therefore relies on functional blockade of the receptor rather than on depletion of the hormone itself. Peak plasma concentrations are reached within 2–4 hours after oral ingestion, and the drug has a terminal elimination half‑life of approximately 5–7 days, allowing once‑daily dosing. Steady‑state levels are typically achieved after 2–3 weeks of continuous therapy.

Conditions Treated with Casodex

• Locally advanced or metastatic prostate cancer – Casodex is indicated for men with disease that has extended beyond the prostate capsule or spread to distant sites. It is used either as monotherapy in patients who have undergone surgical castration (orchiectomy) or in combination with LHRH analogues to achieve combined androgen blockade (CAB).
• Hormone‑refractory (castration‑resistant) prostate cancer – In selected cases, bicalutamide may be continued after disease progression on first‑line hormonal therapy, providing a modest survival benefit.

In the UK, prostate cancer accounts for 22 % of all male cancer diagnoses, and the median age at presentation is 71 years. The inclusion of an AR antagonist such as Casodex in treatment protocols improves biochemical response rates (decline in prostate‑specific antigen) and delays disease progression, which translates into extended overall survival for many patients.

Who is Casodex For?

• Men with newly diagnosed locally advanced or metastatic prostate cancer who are candidates for hormonal therapy.
• Patients who have already undergone surgical castration and require additional receptor blockade to achieve maximal androgen suppression.
• Individuals receiving LHRH analogue therapy (e.g., goserelin, leuprorelin) where CAB is desired to optimise disease control.
• Patients who cannot tolerate steroidal anti‑androgens (such as cyproterone acetate) due to side‑effect profiles; bicalutamide generally causes fewer hepatic and endocrine disturbances.

Casodex is not appropriate for:

• Women or children, because the drug’s anti‑androgenic activity can interfere with normal hormonal development.
• Men with severe hepatic impairment (Child‑Pugh class C) or a history of significant liver disease, given the risk of hepatotoxicity.
• Patients receiving potent CYP3A4 inducers (e.g., rifampicin, carbamazepine) without dose adjustment, as these agents may markedly reduce bicalutamide plasma concentrations.

Clinical assessment, including liver function tests and assessment of comorbidities, is essential before initiating therapy.

Risks, Side Effects, and Interactions

Common

• Hot flashes – transient vasomotor symptoms occurring in up to 30 % of patients.
• Gynecomastia and breast tenderness – estrogenic imbalance leading to palpable breast tissue; may affect up to 15 % of users.
• Gastro‑intestinal upset – nausea, diarrhoea, or constipation, generally mild and self‑limiting.
• Fatigue and weakness – reported in 10–20 % of patients, often related to disease rather than the drug alone.

Rare

• Elevated liver enzymes – alanine aminotransferase (ALT) or aspartate aminotransferase (AST) rise in <5 % of patients; regular monitoring recommended.
• Rash or pruritus – hypersensitivity reactions that may require discontinuation if severe.
• Reduced libido or impotence – secondary to androgen blockade, reported in a minority of men.

Serious

• Severe hepatotoxicity – fulminant hepatic failure is extremely rare but has been described; immediate cessation and medical review are mandatory.
• Pulmonary embolism or deep‑vein thrombosis – occasional reports, particularly in patients with additional thrombotic risk factors.
• Anaphylaxis – life‑threatening allergic reaction; requires emergency management.

Clinically Relevant Interactions

• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, grapefruit juice) – may increase bicalutamide plasma levels, raising the risk of toxicity.
• CYP3A4 inducers (e.g., rifampicin, phenytoin, St John’s wort) – can lower drug exposure, potentially reducing efficacy.
• Warfarin – bicalutamide may enhance anticoagulant effect; INR should be monitored when the two are co‑prescribed.
• Systemic glucocorticoids – additive anti‑androgenic effects may exacerbate endocrine disturbances.
• Estrogen‑containing therapies – increase the likelihood of gynecomastia; patients should be counselled about this risk.

Patients should disclose all prescribed, over‑the‑counter, and herbal products before starting Casodex.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dose – 50 mg (one tablet) taken orally once daily, with or without food. In CAB regimens the dose is often increased to 150 mg daily (three tablets) when combined with an LHRH analogue.
• Renal impairment – no dosage adjustment is required for mild to moderate renal dysfunction; severe failure has not been shown to affect pharmacokinetics markedly.
• Missed dose – if a dose is forgotten, take it as soon as it is remembered unless it is within 12 hours of the next scheduled dose; in that case, skip the missed tablet and resume the regular schedule. Do not double‑dose.
• Overdose – ingestion of more than the prescribed amount may cause nausea, vomiting, diarrhoea, or hepatic enzyme elevation. Management is supportive; activated charcoal may be considered if presentation is within one hour of ingestion. Seek emergency medical care.
• Alcohol – occasional moderate intake does not affect bicalutamide metabolism, but excessive consumption can exacerbate liver toxicity and should be avoided.

Patients are advised to keep a medication diary, especially during the first weeks of therapy, to monitor for adverse effects and adherence.

• Can Casodex be taken while travelling abroad?
  Yes, Casodex may be carried in hand luggage or checked baggage. Keep it in its original packaging with a copy of the prescription or a physician’s letter if travelling to countries that require documentation for import of hormonal agents.

• Does food affect the absorption of bicalutamide?
  Food has a minimal impact on bicalutamide bioavailability. The tablet can be taken with or without meals, according to patient preference.

• What are the inactive ingredients in Casodex tablets?
  Common excipients include microcrystalline cellulose, lactose monohydrate, magnesium stearate, and colloidal silicon dioxide. Patients with severe lactose intolerance should discuss alternatives with their pharmacist.

• Are there any specific warnings for patients of Asian descent?
  Clinical studies have not identified ethnicity‑specific safety concerns for bicalutamide. However, regional prescribing guidelines advise routine liver function monitoring for all patients, regardless of background.

• Can Casodex cause a positive result on drug‑testing programmes?
  Bicalutamide is not typically screened for in standard workplace drug tests. It is not a controlled substance and does not appear on common illicit‑drug panels.

• Is it safe to import Casodex for personal use into the UK?
  Personal import of up to a three‑month supply of a prescription‑only medicine is permitted under UK law, provided the medication has a valid UK marketing authorisation. Our online pharmacy supplies the necessary documentation to facilitate lawful import.

• What historic clinical trial established the efficacy of Casodex?
  The pivotal Phase III trial (the CROSS study) compared bicalutamide 150 mg plus LHRH analogue versus LHRH analogue alone in metastatic prostate cancer. The combination markedly improved overall survival (median 30.7 vs 23.3 months) and became the basis for CAB recommendations.

• How does Casodex compare with older anti‑androgens such as flutamide?
  Bicalutamide has a longer half‑life, allowing once‑daily dosing, and shows a lower incidence of hepatic toxicity compared with flutamide, which requires three times daily dosing and is associated with a higher rate of severe liver injury.
