The active compound is abiraterone, supplied as a 250 mg oral pill. It belongs to the class of steroidal CYP-17 inhibitors, which block androgen production at the adrenal glands, testes, and prostate tumor tissue. The drug is most commonly prescribed for metastatic castration-resistant prostate cancer (mCRPC) and, in combination with low-dose prednisone, for metastatic hormone-sensitive prostate cancer (mHSPC). ## Quick Reference Facts **Active Ingredient** : abiraterone **Form** : pill 250 mg **Primary and Off-Label Uses** : Metastatic castration-resistant prostate cancer (mCRPC) : Metastatic hormone-sensitive prostate cancer (mHSPC) in combination with prednisone : Investigational use in selected adrenal cortical carcinomas (off-label) ## What is Abiraterone? Abiraterone is the generic version of medications that contain the active compound abiraterone. It is marketed under brand names such as **Zytiga** (Janssen Pharmaceuticals). As a generic product, the 250 mg tablet is bioequivalent to the brand formulation, delivering the same systemic exposure when taken as directed. The drug was developed to address the need for an oral androgen-synthesis inhibitor that could be used alongside androgen deprivation therapy (ADT). While the brand version was first approved by the U.S. Food and Drug Administration (FDA) in 2011 for mCRPC, subsequent approvals expanded its indication to earlier stages of disease when combined with prednisone. ## How Abiraterone Works Abiraterone is a potent, irreversible inhibitor of the enzyme CYP-17A1 (17α-hydroxylase/17,20-lyase). This enzyme catalyzes two critical steps in the synthesis of androgens and glucocorticoids from cholesterol. By blocking CYP-17A1, abiraterone dramatically reduces the production of testosterone, dihydrotestosterone, and other adrenal androgens that can stimulate prostate-cancer growth. Because CYP-17A1 also participates in cortisol synthesis, inhibition can lead to a rise in mineralocorticoid precursors, causing hypertension, hypokalemia, and fluid retention. To counteract this hormonal imbalance, patients are co-prescribed low-dose prednisone (5 mg twice daily). Prednisone replaces the missing glucocorticoid activity and suppresses excess mineralocorticoid production. Pharmacokinetically, abiraterone is rapidly absorbed after oral administration, with peak plasma concentrations occurring within 2-3 hours. Food, especially a high-fat meal, can increase absorption by up to 60 percent, which may affect tolerability. The drug is extensively metabolized in the liver, primarily via CYP3A4, and is eliminated mainly in the feces (≈85 %). Its terminal half-life is about 12 hours, supporting once-daily dosing. ## Conditions Treated with Abiraterone - **Metastatic Castration-Resistant Prostate Cancer (mCRPC)** In men whose disease progresses despite surgical or medical castration, abiraterone further suppresses residual androgen production, slowing tumor growth and extending overall survival. - **Metastatic Hormone-Sensitive Prostate Cancer (mHSPC) + Prednisone** When added early in the disease course, abiraterone combined with prednisone enhances the effectiveness of standard ADT, delaying progression to castration resistance and improving survival outcomes. - **Castration-Resistant Prostate Cancer with Prior Chemotherapy** Clinical trials have demonstrated that abiraterone benefits patients who have previously received docetaxel, offering an oral alternative to further lines of therapy. ## Is Abiraterone the Right Medication for You? Abiraterone is appropriate for adult men with advanced prostate cancer who are already receiving androgen deprivation therapy and have either metastatic castration-resistant disease or metastatic hormone-sensitive disease. Ideal candidates are those who can tolerate concomitant low-dose prednisone and have adequate liver function (bilirubin ≤1.5 × ULN and AST/ALT ≤2.5 × ULN). The medication is less suitable for patients with severe hepatic impairment, uncontrolled hypertension, or active cardiac failure, because mineralocorticoid excess can exacerbate these conditions. Individuals with known hypersensitivity to abiraterone or any of its excipients should avoid it. Patients who cannot take prednisone (e.g., due to uncontrolled diabetes or severe gastrointestinal disorders) may need alternative androgen-synthesis inhibitors. Always discuss personal medical history, current medications, and laboratory results with a qualified healthcare professional before initiating therapy. ## Buying Abiraterone from [our online pharmacy](https://liabilis.com/order-abiraterone-online-en.html) ### Why Choose Our Service?

Prednisone 5 mg is taken twice daily (morning and evening) to mitigate mineralocorticoid effects. - **Missed Dose** If a dose is forgotten and it is less than 12 hours until the next scheduled dose, skip the missed tablet and resume the regular schedule. Do **not** take a double dose to “catch up.” - **Overdose** In the event of accidental ingestion of more than the prescribed amount, seek immediate medical attention. Symptoms may include severe hypertension, profound hypokalemia, or hepatic dysfunction. Provide the exact amount taken and the time of ingestion to healthcare professionals. - **Practical Precautions** - Take the medication on an empty stomach (at least 1 hour before or 2 hours after food). - Avoid grapefruit juice, which can increase abiraterone plasma concentrations via CYP3A4 inhibition. - Do not consume alcohol excessively, as it may potentiate liver toxicity. - Refrain from operating heavy machinery if you experience dizziness or severe fatigue. ## Safety Information ### ⚠️ Who Should Not Take Abiraterone - Patients with severe hepatic impairment (Child-Pugh C). - Individuals with uncontrolled hypertension (BP > 160/100 mmHg) or active cardiac failure. - Those with documented hypersensitivity to abiraterone acetate or any tablet excipient. - Patients who cannot safely take concomitant low-dose prednisone (e.g., uncontrolled diabetes, active peptic ulcer disease). ### Common Side Effects - **Hypertension** - reported in up to 20 % of patients; monitor blood pressure regularly. - **Hypokalemia** - low potassium may cause muscle cramps; supplementation may be advised. - **Fluid retention/Edema** - assess for swelling of ankles or sudden weight gain. - **Fatigue** - often mild to moderate; maintain adequate rest. - **Gastrointestinal upset** - nausea or abdominal discomfort; take with water and follow fasting instructions. ### Serious Side Effects (Seek Immediate Medical Help) - **Adrenal insufficiency** - severe fatigue, abdominal pain, vomiting, or low blood pressure after abrupt prednisone discontinuation. - **Liver injury** - jaundice, dark urine, right-upper-quadrant pain; check liver function tests promptly. - **Severe cardiac events** - chest pain, sudden shortness of breath, or palpitations. - **Allergic reactions** - rash, itching, swelling of the face or throat, or difficulty breathing. ### Drug & Food Interactions - **Strong CYP3A4 inhibitors** (e.g., ketoconazole, clarithromycin) - may increase abiraterone levels; dose adjustment or alternative therapy may be required. - **CYP3A4 inducers** (e.g., rifampin, phenytoin) - may reduce efficacy; close monitoring is needed. - **Mineralocorticoid receptor antagonists** (e.g., eplerenone, spironolactone) - combined use can lead to dangerous hyper-kalemia. - **Anticoagulants** - abiraterone may enhance the effect of warfarin; monitor INR more frequently. - **High-fat meals** - increase absorption; avoid taking the drug with large fatty meals to reduce variability. ## Off-Label and Investigational Uses of Abiraterone - **Adrenocortical carcinoma** - Small case series have reported tumor-size reduction when abiraterone is combined with glucocorticoids, reflecting its ability to suppress adrenal steroidogenesis. - **Triple-negative breast cancer** - Early-phase trials are exploring androgen-axis inhibition in select hormone-receptor-negative tumors, though results remain preliminary. These applications are not approved by regulatory agencies and should only be pursued within clinical-trial settings or under strict specialist supervision. ## Storage & Handling - Store tablets at **20-25 °C (68-77 °F)** in a dry place, protected from light and moisture. - Keep the container tightly closed; avoid exposure to extreme temperatures. - Do not use tablets beyond the printed expiration date. - Dispose of unused medication according to local pharmacy take-back programs or hazardous-waste guidelines. ## Frequently Asked Questions **Practical Use & Lifestyle** - **Can I travel internationally with abiraterone?** Yes, but carry the medication in its original packaging with a copy of the prescription. Check the destination country’s import regulations for controlled substances. - **Will grapefruit juice affect my abiraterone therapy?** Grapefruit inhibits CYP3A4, increasing drug levels and the risk of hypertension or liver toxicity. It is safest to avoid grapefruit while taking abiraterone. - **How should I time my prednisone doses relative to abiraterone?** Take prednisone twice daily (morning and evening) regardless of when you ingest abiraterone. This schedule maintains steady glucocorticoid coverage. **Product & Formulation Details** - **What do abiraterone tablets look like?** The generic 250 mg tablet is round, film-coated, and typically white to off-white with “ABIR” imprint; appearance may vary slightly between manufacturers. - **Can the tablet be split or crushed?** The tablet should be swallowed whole. Splitting may affect the dose uniformity, and crushing could increase exposure to staff handling the medication. **Regulatory & Safety Nuances** - **Is abiraterone detectable on standard drug tests?** Routine occupational drug screens do not target abiraterone. However, specialized mass-spectrometry assays can detect it if specifically requested. - **Are there special warnings for elderly patients?** Older adults often have reduced hepatic reserve and may be more susceptible to hypertension and electrolyte disturbances; close monitoring of blood pressure and serum potassium is advisable. **Scientific & Clinical Curiosity** - **What pivotal trial led to abiraterone’s approval?** The COU-AA-301 phase III trial demonstrated a median overall-survival advantage of 4.8 months versus prednisone alone in mCRPC patients, forming the basis for FDA approval. - **How does abiraterone differ from earlier androgen-synthesis inhibitors?** Unlike ketoconazole, which non-specifically inhibits multiple steroidogenic enzymes, abiraterone selectively targets CYP-17A1, offering greater potency with a clearer safety profile when combined with steroid supplementation. ## Glossary **CYP-17A1 (17α-Hydroxylase/17,20-Lyase)** : An enzyme essential for converting pregnenolone and progesterone into androgen precursors; inhibition reduces testosterone synthesis. **Mineralocorticoid Excess** : A hormonal imbalance characterized by elevated aldosterone-like activity, leading to hypertension, low potassium, and fluid retention. **Bioequivalence** : The condition where a generic drug demonstrates no significant difference in rate and extent of absorption compared with the brand reference product. ## Disclaimer The information provided about **Abiraterone** is intended for general educational purposes and does not substitute professional medical consultation.
