Generic Aczone (Diaminodiphenyl sulfone)

Introduction

Aczone is a prescription medication that contains the active compound Diaminodiphenyl sulfone (commonly known as dapsone). It is supplied as a 100 mg oral tablet and belongs to the class of anti-infective and anti-inflammatory agents. The primary approved indication for oral Aczone in most jurisdictions is the treatment of leprosy (Hansen’s disease) and certain dermatologic conditions such as dermatitis herpetiformis. The drug is also employed in combination therapy for pneumocystis pneumonia prophylaxis in immunocompromised patients.

What is Aczone?

Aczone is the branded formulation of the generic molecule Diaminodiphenyl sulfone. The drug was originally developed in the s as an antibacterial agent and later found utility in immune-mediated skin disorders. It is marketed in several countries under brand names such as Aczone and Dapsone, reflecting its established role in dermatology and infectious disease. The manufacturer of the branded tablet varies by region, but all reputable sources adhere to Good Manufacturing Practices (GMP).

How Aczone Works

Diaminodiphenyl sulfone exerts its therapeutic effect through two principal mechanisms:

• Antimicrobial action - The molecule interferes with the synthesis of folic acid in susceptible bacteria, particularly Mycobacterium leprae. By inhibiting dihydropteroate synthase, it prevents nucleic acid formation and ultimately bacterial replication.

• Anti-inflammatory effect - In the skin, dapsone suppresses neutrophil chemotaxis and reduces the release of inflammatory mediators such as myeloperoxidase. This dampening of the innate immune response accounts for its efficacy in dermatitis herpetiformis and other neutrophil-driven dermatoses.

Peak plasma concentrations are reached within 2-4 hours after oral ingestion, and the drug’s half-life ranges from 20 to 30 hours, allowing once-daily dosing in most patients. Renal excretion accounts for the majority of clearance, with a smaller fraction eliminated unchanged in the urine.

Conditions Treated with Aczone

• Leprosy (Hansen’s disease) - Oral Aczone is a cornerstone of multidrug therapy (MDT) regimens recommended by the World Health Organization. It reduces bacterial load and prevents disease progression.
• Dermatitis herpetiformis - The anti-inflammatory properties alleviate the intensely pruritic papulovesicular rash associated with this gluten-sensitivity-related condition.
• Pneumocystis jirovecii pneumonia (PCP) prophylaxis - In patients intolerant to trimethoprim-sulfamethoxazole, low-dose dapsone (often 100 mg daily) is used as an alternative preventive agent.

These indications are supported by regulatory approvals from agencies such as the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA).

Off-Label and Investigational Uses of Aczone

• Bullous pemphigoid - Small case series have reported clinical improvement when dapsone is added to standard corticosteroid therapy. Evidence is limited to uncontrolled observations.
• Linear IgA disease - Some dermatologists prescribe dapsone off-label based on its ability to suppress IgA-mediated neutrophil activation. Controlled trials are lacking.
• Refractory hidradenitis suppurativa - Preliminary investigations suggest that dapsone may reduce inflammatory nodules, but the data remain investigational.

These off-label applications have not received formal approval from regulatory bodies. Patients should discuss potential benefits and risks with a qualified healthcare provider before initiating such therapy.

Is Aczone the Right Medication for You?

Aczone is most appropriate for adult patients who have a confirmed diagnosis of leprosy, dermatitis herpetiformis, or who require PCP prophylaxis and cannot tolerate first-line agents. The drug is particularly valuable when bacterial resistance to other antimicrobials is a concern or when rapid control of skin inflammation is needed.

Contraindications include:

• Known hypersensitivity to dapsone or any excipients in the tablet.
• Severe glucose-6-phosphate dehydrogenase (G6PD) deficiency, due to risk of hemolytic anemia.
• Pregnancy (category B in some regions) unless the potential benefit outweighs risk, as fetal exposure is not well studied.

Patients with moderate hepatic or renal impairment may require dose adjustment and close monitoring.

Risks, Side Effects, and Interactions

Common

• Methemoglobinemia - A blue-tinged discoloration of the blood that may cause shortness of breath. Usually dose-related and reversible upon discontinuation.
• Peripheral neuropathy - Numbness or tingling in the extremities; monitoring is advised for long-term use.
• Gastrointestinal upset - Nausea, abdominal pain, or loss of appetite.

Rare

• Hypersensitivity syndrome - Fever, rash, eosinophilia, and organ involvement; requires immediate medical attention.
• Severe hemolysis - Particularly in patients with undiagnosed G6PD deficiency.

Serious

• Aplastic anemia - Bone-marrow failure leading to pancytopenia; rare but potentially fatal.
• Steven-Johnson syndrome / Toxic epidermal necrolysis - Life-threatening skin reactions; discontinue the drug at the first sign.

Drug-Drug Interactions

• Anticoagulants (warfarin) - Dapsone may potentiate anticoagulant effect; monitor INR closely.
• Sulfonylureas - Potential for enhanced hypoglycemia.
• Rifampin - Induces hepatic enzymes, lowering dapsone plasma levels and possibly reducing efficacy.

Drug-Food Interactions

• Alcohol - May exacerbate hemolysis and increase the risk of liver toxicity.
• High-dose vitamin C - Can increase the formation of methemoglobin; avoid excessive supplementation while on Aczone.

Patients should avoid operating heavy machinery or driving until they know how Aczone affects them, especially during the initiation phase.

Use: Dosing, Missed Dose, Overdose

• Standard dosing - For leprosy, the usual adult dose is 100 mg orally once daily, combined with other antimicrobials as part of MDT. For dermatitis herpetiformis, the same dose is typical, adjusted based on clinical response and tolerance.
• Missed dose - Take the missed tablet as soon as you remember, unless it is near the time of the next scheduled dose. In that case, skip the missed dose and resume the regular dosing interval; do not double-dose.
• Overdose - Symptoms may include severe nausea, vomiting, abdominal pain, methemoglobinemia, and cyanosis. Seek emergency medical care immediately; treatment may involve supportive measures and administration of methylene blue for methemoglobinemia.

Practical precautions - Aczone tablets may be taken with or without food. Alcohol should be limited, and patients should stay well-hydrated to aid renal clearance.

FAQ

• What is the appearance of an Aczone 100 mg tablet?

  • The tablet is typically round, white to off-white, and may bear the imprint “Acz 100” on one side. Inert fillers include lactose and magnesium stearate.

• Can Aczone be stored in a humid climate?
