Overview of Allopurinol Wockhardt

Quick Facts: Identity and Classification

Allopurinol Wockhardt contains the active ingredient Allopurinol, is supplied in tablet form, belongs to the Pharmacological class of Xanthine Oxidase Inhibitors (XOI), is generally utilized for conditions linked to high urate levels, and is a synthetic compound.


What Type of Medicine is Allopurinol Wockhardt?

Allopurinol Wockhardt is a prescription-only pharmaceutical preparation supplied as tablets, classified pharmacologically as a Xanthine Oxidase Inhibitor (XOI). This product, specifically formulated by the manufacturer Wockhardt, contains Allopurinol as its single active ingredient. It is recognized as an effective urate-lowering medication (ULM). Allopurinol is chemically identified as a purine analogue because its molecular structure is similar to the natural purine base hypoxanthine, enabling it to interact with the targeted enzyme in the body. The medication is manufactured for oral administration, meaning its effects are systemic throughout the body.


Allopurinol: Composition and General Benefit

The core composition involves the active ingredient Allopurinol, which functions to reduce the body’s production of uric acid. The mechanism involves the active ingredient, or its primary metabolite oxipurinol, effectively blocking the enzyme xanthine oxidase (XOR). This enzyme is the critical biological step responsible for converting purines into uric acid. Xanthine oxidase inhibitor (XOI) compounds are used in managing urate metabolism, as the drug's action is fundamentally about interrupting the chemical pathway that creates the substance. This class of medication is clinically recognized for its role in the long-term chemical management of conditions associated with excess uric acid, such as chronic hyperuricemia. By consistently restricting the formation of uric acid, the essential therapeutic purpose of this medication is to maintain lower concentrations of urate in the bloodstream, thereby providing management for the underlying chemical imbalance known as hyperuricemia.

What side effects are possible with Allopurinol Wockhardt?

Possible Side Effects and Safety Information

The safety profile of Allopurinol is officially documented by regulatory authorities, with adverse reactions categorized by frequency and the body system affected. These classifications communicate the range of documented risks associated with the medicine.

Classification Examples of Officially Listed Adverse Reactions
Common Skin rash, increase in blood thyroid stimulating hormone (TSH) levels (in certain studies).
Uncommon Hypersensitivity reactions (non-severe), nausea, vomiting, abnormal liver function tests.
Rare Severe skin reactions (SJS/TEN), hepatitis.

These reactions are grouped into System-Organ Classes including Skin and Subcutaneous Tissue Disorders, Gastrointestinal Disorders, Hepatobiliary Disorders, and Blood and Lymphatic System Disorders.

Serious Adverse Reactions (SCAR) are rare but clinically significant events highlighted in official prescribing information. These include Stevens-Johnson Syndrome (SJS), Toxic Epidermal Necrolysis (TEN), and DRESS syndrome. Other serious reactions include severe Hepatotoxicity and certain blood disorders (e.g., aplastic anaemia, agranulocytosis).

Specific safety considerations are noted for certain populations. Patients with impaired renal function require dosage adjustments and may face a higher risk of adverse effects. Additionally, patients of Han Chinese, Thai, or Korean origin have a higher risk of severe cutaneous adverse reactions (SCAR), which is associated with a specific genetic marker.

Time-related patterns are also documented: an increase in acute gout attacks may be observed at the initiation of therapy, and the highest risk for serious skin reactions generally occurs within the first few months of treatment.

Overdose and Emergency Response

An overdose of Allopurinol Wockhardt requires immediate medical attention as defined by official regulatory authorities. Overexposure may initially manifest with acute gastrointestinal distress, including nausea, vomiting, and diarrhea. The critical, potentially life-threatening outcome documented in regulatory labeling involves the formation of Xanthine Crystalluria. This accumulation of metabolites can lead to nephropathy and subsequent acute renal failure.

In the event of a suspected overdose, it is mandated that patients seek immediate medical attention and present for hospital evaluation. Official prescribing information confirms that no specific antidote is known for Allopurinol intoxication. Consequently, management is strictly symptomatic and supportive. Regulatory guidance describes specific interventions, including the maintenance of adequate diuresis to facilitate the excretion of allopurinol and its metabolites. For cases of severe intoxication or in patients with existing renal compromise, hemodialysis is an officially recognized procedure for the removal of the active compound. Furthermore, regulatory documents note that patients with pre-existing renal impairment are at increased risk for toxicity and severe outcomes due to impaired drug clearance. Hospital monitoring of both renal function and hepatic function is required following overexposure.

Eligibility and Restrictions for Use

Eligibility scope

Adult patients are the primary eligible population for all labeled indications. Pediatric use is officially restricted and rarely indicated, limited to specific conditions like malignancy-related hyperuricemia or Lesch-Nyhan syndrome.

Populations for whom use is contraindicated

The medicine is contraindicated in patients with a history of severe reaction or hypersensitivity to allopurinol or any of its components. Use is not recommended for the treatment of asymptomatic hyperuricemia or in breastfeeding women. Individuals of Han Chinese, Thai, or Korean descent who carry the *HLA-B5801 allele** are at a higher risk of severe hypersensitivity; use in this population is restricted unless clinical benefits clearly outweigh the risk.

Eligibility-related restrictions

Treatment must not be initiated during an acute attack of gout until the episode has fully subsided. Patients with renal impairment or hepatic impairment require a reduced dosage and caution, as the drug and its active metabolite accumulate when kidney function is decreased. Use during pregnancy is generally not recommended unless the potential benefit justifies the risk.

Eligibility classifications (high-level)

Eligibility is defined by Contraindications (absolute prohibition), the condition of Not Recommended (high-risk or no labeled indication), and the requirement for Use with Caution (due to organ function or concurrent risk factors).

What should I know about interactions with other medicines?

Allopurinol interacts with certain medicines by affecting their metabolism or increasing the risk of adverse reactions, requiring careful management by a healthcare professional.

Major Interactions Requiring Dose Reduction

Interacting Medicine Category Examples Interaction Effect & Management
Purine Analogues Mercaptopurine, Azathioprine Allopurinol inhibits xanthine oxidase, the enzyme that inactivates these drugs. This increases their active concentration significantly, leading to a high risk of severe toxicity, such as bone marrow suppression. The dose of the purine analogue must be substantially reduced (typically to 25–35% of the original dose) and blood counts must be monitored closely.
Coumarin Anticoagulants Warfarin Allopurinol can enhance the anticoagulant effect, increasing the risk of bleeding. Coagulation parameters (e.g., INR) must be monitored frequently, and the anticoagulant dose may require adjustment.
Cytotoxic Agents Capecitabine, Bendamustine Co-administration is generally not recommended or avoided due to an increased risk of severe toxicity.

Other Documented Interactions

Concomitant use with certain medicines may increase the risk of hypersensitivity and severe skin reactions. These medicines include thiazide diuretics (especially in patients with kidney impairment), Angiotensin Converting Enzyme (ACE) inhibitors, and the antibiotics Ampicillin and Amoxicillin. The plasma concentration of Theophylline (a bronchodilator) may be increased, necessitating therapeutic drug monitoring and potential dose adjustment. Similarly, the drug Didanosine may have its levels and potential for adverse effects increased.

Mechanism of Action

The following mechanism-of-action text strictly adheres to the stated constraints.

Primary Target: Enzyme Inactivation and Production Blockade

The drug's primary action involves the active ingredient Allopurinol and its key metabolite, Oxipurinol, targeting and inhibiting the enzyme Xanthine Oxidase (XO). This enzyme is responsible for the final synthesis of Uric Acid from intermediate purine bases. By inactivating this enzyme, the drug blocks the production of uric acid, resulting in a change in the plasma concentration of urate.


Secondary Effect: Metabolite Shift and Enhanced Clearance

The inhibition of Xanthine Oxidase causes the intermediate purine bases, hypoxanthine and xanthine, to accumulate instead of becoming uric acid. These precursors are more water-soluble than uric acid, facilitating their renal excretion. Furthermore, the elevated levels of these purine bases engage a feedback mechanism that supports the suppression of the body's de novo creation of new purines, contributing to the overall change in urate balance.


Physiological Consequence: Crystal Dissolution

The sustained change in systemic urate concentration creates a chemical gradient that shifts the body from a state of urate supersaturation to one of under-saturation. This physiological shift promotes the dissolution and mobilization of pre-existing, solid urate deposits (monosodium urate crystals) from tissues back into the circulation. This dissolution process is necessary for the overall process of reducing the body's total urate content.

Dosage and Administration Information

How to Use Allopurinol Wockhardt

Allopurinol is used according to a structured protocol to ensure consistent long-term administration. The primary route of administration for chronic therapy is oral (tablet form), with an Intravenous (IV) formulation available for patients unable to take oral medication, such as during cancer treatment prophylaxis.


Official Dosing and Frequency

The typical protocol involves starting with a low daily dose, often 100 mg, followed by a process of titration where the dose is gradually increased until the maintenance target is achieved. Daily doses range from 100 mg to 300 mg for maintenance, with a maximum official dose of up to 800 mg or 900 mg daily for severe conditions. Standard therapy requires the medicine to be taken once daily; however, total daily doses exceeding 300 mg must be administered in divided doses to improve absorption and tolerability.


Administration Conditions and Adjustments

For optimal intake, the oral tablets are instructed to be taken after meals or with food to minimize potential irritation. Adequate consumption of fluid is also advised to maintain high fluid output. Treatment should not be initiated during an acute gout attack, but only after the flare-up has completely subsided. A critical administration rule involves dose reduction for patients with renal impairment, with specific regimens detailed for varying levels of kidney function.

Recent Clinical Evidence

Research evidence / Overview of studies for Allopurinol Wockhardt

The research evidence for Allopurinol has been compiled over several decades, focusing primarily on research exploring how systemic urate levels are affected. The following overview describes the types of studies that exist for its key uses, what outcomes the researchers monitored, and what aspects of the evidence remain limited or uncertain.


Evidence for Long-Term Management of Gout and Chronic Hyperuricemia

The core research for this medicine consists of many Randomized Controlled Trials (RCTs) and large-scale meta-analyses that contribute to the evidence landscape exploring the condition of high urate levels.

Researchers primarily measured shifts in the serum urate (SU) level and the proportion of individuals who achieved specific, predefined low-urate targets. Trials also monitored clinical outcomes related to the symptoms of gout, such as changes in the frequency of acute gout flares and any observed changes in the size of tophi (urate crystal deposits). Studies monitored how symptoms evolved in the observed populations, and the findings describe patterns observed in these trials.

Research regarding the observed biochemical shifts in urate levels is considered well-established; however, what remains uncertain is whether long-term urate level shifts affect joint integrity and patient functioning over many years. Furthermore, the findings describing patterns in the recurrence rate of acute gout flares have sometimes varied across different trials, and follow-up durations were limited in some of the original studies.


Evidence for Preventing Uric Acid-Related Kidney Issues During Cancer Treatment

Allopurinol was studied for a specific supportive role in oncology settings, particularly in adult and pediatric patients receiving chemotherapy that carries a high risk of rapidly increasing uric acid levels, which are of clinical concern in this setting.

Regulatory reviews reference the research related to urate levels in this context. Researchers monitored the control of serum urate levels immediately before and after cytotoxic treatment, and they tracked observations related to the stability of kidney function during this high-risk period. The research focus is necessarily short-term; consequently, long-term patient follow-up data for this specific use are limited.


Research on Long-Term Outcomes, Durability, and Cardiovascular Endpoints

Research has also explored outcomes beyond changes in urate levels, particularly the long-term effects on cardiovascular health and mortality. Data from these large-scale RCTs reported findings that did not indicate a clear difference in the incidence of cardiovascular events (MACEs or mortality) when comparing the treatment to usual care or other comparators.

Certainty remains low for any claimed direct cardiovascular effect. It is not yet fully established whether this medicine affects cardiovascular outcomes beyond its observed action on urate levels.
