Generic Zyloprim Information

Introduction

Zyloprim is a therapeutic agent used primarily to lower serum uric acid levels in adults. Its active ingredient, allopurinol, inhibits the enzyme xanthine oxidase, thereby reducing the production of uric acid. In Hong Kong, elevated uric acid is a common contributor to gout and certain forms of kidney stone disease, and Zyloprim is classified within the arthritis medication group for its role in managing gout‑related inflammation. The product is supplied by reputable manufacturers and is approved for use in the treatment of hyperuricaemia and gout prophylaxis.

What is Zyloprim?

Zyloprim is a tablet formulation containing the generic compound allopurinol. It is produced by licensed pharmaceutical firms that follow Good Manufacturing Practice (GMP) standards. The medication belongs to the xanthine oxidase inhibitor class, a subgroup of anti‑gout agents. While Zyloprim is marketed under its own brand name, it contains the same active molecule as other well‑known allopurinol brands such as Aloprim, Allopurinol‑EC, and Zyloprim®. Our online pharmacy provides this generic alternative as a cost‑effective treatment option for patients in Hong Kong.

How Zyloprim Works

Allopurinol, the active component of Zyloprim, competitively inhibits xanthine oxidase, an enzyme responsible for converting hypoxanthine to xanthine and xanthine to uric acid. By reducing the enzymatic activity, Zyloprim decreases the generation of uric acid, leading to lower serum urate concentrations.

• Onset of action: Serum urate levels typically begin to fall within 2–4 hours after the first dose.
• Peak effect: Maximum reduction is usually observed after 5–7 days of consistent therapy.
• Duration & clearance: Allopurinol is metabolised to oxypurinol, which has a longer half‑life (≈ 18–30 hours) and continues to inhibit xanthine oxidase after drug discontinuation. Renal excretion accounts for the primary route of clearance; dose adjustment is required in patients with impaired kidney function.

The lowered uric acid concentration reduces crystal formation in joints and kidneys, thereby preventing acute gout attacks and chronic joint damage.

Conditions Treated with Zyloprim

• Gout (hyperuricaemic arthritis): Primary indication; Zyloprim prevents urate crystal deposition and recurrent attacks.
• Hyperuricaemia associated with chemotherapy: Certain anticancer regimens increase uric acid; Zyloprim mitigates tumour lysis syndrome.
• Kidney stones composed of uric acid: By lowering urinary urate supersaturation, Zyloprim helps prevent stone formation.

In Hong Kong, gout prevalence is estimated at 5–7 % of the adult population, increasing with age and dietary patterns rich in purines. Hyperuricaemia is also a recognized risk factor for cardiovascular disease, making effective urate‑lowering therapy clinically important.

Who is Zyloprim For?

Zyloprim is appropriate for adult patients who:

• Have a documented diagnosis of gout or chronic hyperuricaemia.
• Experience recurrent gout flares despite lifestyle modification.
• Are undergoing chemotherapy regimens that predispose to tumour lysis syndrome.
• Have a history of uric acid kidney stones.

Contraindications include:

• Severe hypersensitivity to allopurinin or any tablet component.
• Acute gout attacks without concurrent anti‑inflammatory therapy (initiation may exacerbate inflammation).
• End‑stage renal disease not on dialysis (dose must be reduced or alternative therapy considered).

Risks, Side Effects, and Interactions

Common

• Skin rash – mild erythema or pruritus; often transient.
• Gastrointestinal discomfort – nausea, dyspepsia, or mild diarrhoea.
• Elevated liver enzymes – mild transaminase rise observed in routine monitoring.

Rare

• Stevens‑Johnson syndrome / toxic epidermal necrolysis – severe mucocutaneous reactions requiring immediate discontinuation.
• Acute interstitial nephritis – characterised by fever, rash, and renal function decline.
• Hypersensitivity syndrome – fever, eosinophilia, and multi‑organ involvement.

Serious

• Allopurinol‑induced severe cutaneous adverse reactions (SCARs) – may be life‑threatening; risk heightened in patients with HLA‑B*58:01 allele, more prevalent among Asian populations.
• Bone marrow suppression – rare cytopenias reported, necessitating periodic blood count monitoring.
• Pancreatitis – isolated case reports; patients should seek medical advice if abdominal pain occurs.

Drug–Drug Interactions

• Azathioprine / Mercaptopurine: Allopurinol reduces clearance, increasing toxicity; dose of the thiopurine must be reduced to ≤ 25 % of the original.
• Warfarin: May enhance anticoagulant effect; INR monitoring is advised.
• Thiazide diuretics: Can increase serum uric acid, potentially diminishing Zyloprim’s efficacy; dose adjustment may be required.
• ACE inhibitors (e.g., captopril): May raise allopurinol plasma concentration; monitor for adverse reactions.

Patients should disclose all concomitant medications, including over‑the‑counter products and herbal supplements, to their healthcare provider.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing: 100 mg once daily for mild hyperuricaemia; typical gout prophylaxis starts at 100 mg daily, titrated up to 300 mg daily based on urate levels and renal function.
• Renal adjustment:
  • CrCl ≥ 50 mL/min – usual dose.
  • CrCl 30–49 mL/min – maximum 200 mg/day.
  • CrCl < 30 mL/min – limit to 100 mg every other day; consider alternative agents.
• Missed dose: Take the missed tablet as soon as remembered unless it is close to the next scheduled dose; do not double‑dose.
• Overdose: Symptoms may include severe rash, gastrointestinal upset, or renal impairment. Seek immediate medical attention; supportive care and monitoring of renal function are the mainstays of treatment.
• Precautions:
  • Take with food or milk to minimise gastrointestinal irritation.
  • Avoid excessive alcohol, which can raise uric acid and potentiate gout attacks.
  • Maintain adequate hydration (≈ 2–3 L water/day) unless contraindicated by cardiac or renal disease.

FAQ

• **Can Zyloprim be taken with other gout medications?**
  Yes, Zyloprim is often used together with anti‑inflammatory agents such as colchicine or NSAIDs during the initiation phase. Combination therapy should be guided by a physician to avoid overlapping toxicities.

• **Is there a difference in tablet appearance between regions?**
  In most markets, Zyloprim tablets are round, scored, and film‑coated, typically white or off‑white. Formulations sold in Europe may use a distinctive imprint, whereas Asian‑sourced tablets often carry a numeric code denoting strength.

• **Does Zyloprim require special storage conditions in Hong Kong’s humid climate?**
  The medication should be stored at controlled room temperature (15‑30 °C) in a dry place. High humidity can affect tablet integrity over prolonged periods; keeping the container tightly sealed mitigates this risk.

• **Can Zyloprim be imported for personal use without a prescription?**
  Hong Kong permits personal import of a three‑month supply of a medication for personal use, provided the product is not a controlled substance and the importer can present a copy of the prescription. Our online pharmacy assists customers in complying with local import regulations.

• **Are there known genetic risk factors for severe reactions to Zyloprim in Asian populations?**
  The HLA‑B*58:01 allele, more prevalent among Han Chinese, Korean, and Japanese individuals, is strongly associated with allopurinol‑induced SCARs. Patients with a known positive test should avoid allopurinol–containing products.

• **What is the historical significance of allopurinol in gout management?**
  Discovered in the 195s, allopurinol became the first specific urate‑lowering therapy and has remained the cornerstone of chronic gout management for over six decades, supported by robust randomized clinical trial data.

• **How does Zyloprim compare with febuxostat for urate reduction?**
  Both agents inhibit xanthine oxidase, but febuxostat is a non‑purine selective inhibitor with a longer half‑life and is less affected by renal function. Allopurinol (Zyloprim) is generally first‑line due to lower cost and extensive safety data; febuxostat is reserved for patients intolerant to allopurinol.

• **Is Zyloprim safe for patients with cardiovascular disease?**
  Large observational studies have not demonstrated an increased cardiovascular risk with allopurinol; some data even suggest a modest protective effect. Nonetheless, patients with severe heart failure should be monitored closely, especially when dose adjustments affect renal clearance.

• **What are the inert ingredients in Zyloprim tablets?**
  Common excipients include lactose monohydrate, microcrystalline cellulose, magnesium stearate, and a film‑coating polymer (hydroxypropyl methylcellulose). Patients with specific allergies should review the full ingredient list supplied by the pharmacy.

• **Can Zyloprim be taken while traveling across time zones?**
  Yes, maintaining a consistent once‑daily schedule is essential. If crossing multiple time zones, adjust the dosing time gradually (e.g., shift by 1–2 hours per day) to avoid missed doses.

• **Does Zyloprim have any impact on laboratory drug testing?**
  Allopurinol and its metabolite oxypurinol may be detectable in urine drug screens, but they are not considered performance‑enhancing substances and typically do not affect standard workplace testing panels.
