Lamprene

Clofazimine, the active ingredient in Lamprene, is a phenazine dye presented as a 100 mg oral capsule for oral use. It is indicated for the treatment of multibacillary leprosy and for adjunct therapy of Mycobacterium avium complex infections, particularly in patients with compromised immune systems.

GNH USA supplies Lamprene as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, providing quality‑assured products to a global network of healthcare institutions and adhering to EU GMP standards, and supports reliable supply chains across Europe, Asia and the Americas.

Clofazimine is employed in the management of mycobacterial infections, primarily targeting leprosy and related conditions.

- Multibacillary leprosy: reduces bacterial load and contributes to clinical remission. - Mycobacterium avium complex infections: used as adjunct therapy to improve outcomes in immunocompromised patients. - Leprosy reaction (erythema nodosum leprosum): helps modulate inflammatory response and alleviate symptoms.

Clofazimine may cause a range of adverse reactions, varying in frequency and severity.

Common Side Effects: - Skin discoloration: brown to black pigmentation of the skin. - Gastrointestinal upset: nausea, abdominal pain, or dyspepsia. - Pruritus: itching, sometimes with rash. - Mild headache.

Serious or Rare Side Effects: - Photosensitivity: increased risk of sunburn. - Severe cutaneous reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Hepatotoxicity: elevated liver enzymes or liver injury. - Hematologic abnormalities: neutropenia, eosinophilia, or anemia.

When prescribing Clofazimine, clinicians should consider several precautionary measures to ensure safe use. - Pregnancy: safety not established; avoid unless benefits outweigh risks. - Breastfeeding: unknown; monitor infant for discoloration. - Renal impairment: use with caution; dose adjustment may be required. - Hepatic impairment: monitor liver function tests regularly. - Skin discoloration: counsel patients about reversible and permanent pigmentation changes. - Store at ambient temperature: keep below 25 °C in the original container, protect from moisture and light.

Clofazimine can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid): - Rifampicin: induces metabolism, reducing Clofazimine levels. - Protease inhibitor antiretrovirals: may increase toxicity. - Warfarin: potential additive anticoagulant effect.

Moderate Interactions (Monitor Closely): - Macrolide antibiotics (e.g., azithromycin): may increase QT prolongation risk. - Antifungal azoles (e.g., ketoconazole): may affect Clofazimine clearance. - Diabetes medications: monitor blood glucose as Clofazimine may affect glucose control.
