Amphotericin B

Amphotericin B is a potent antifungal medication used to treat severe fungal infections that affect the lungs, brain, and bloodstream. It belongs to the polyene class of antifungals and is commonly used in life-threatening infections such as cryptococcal meningitis, aspergillosis, and systemic candidiasis. Amphotericin B is available in different formulations, including lipid-based versions, to reduce toxicity. It is administered under medical supervision, usually via intravenous infusion.

Uses of Amphotericin B

• Treatment of systemic fungal infections
• Management of cryptococcal meningitis
• Used in aspergillosis and mucormycosis
• Effective against leishmaniasis
• Treatment of fungal infections in immunocompromised patients

How Amphotericin B Works

Amphotericin B binds to the fungal cell membrane and disrupts its integrity, causing essential cellular components to leak out. This action ultimately leads to the death of the fungal cell. It is highly effective against a broad range of fungal infections but can have serious side effects, requiring careful monitoring.

Benefits of Amphotericin B

• Highly effective against life-threatening fungal infections
• Broad-spectrum antifungal activity
• Available in lipid-based formulations to reduce toxicity
• Essential treatment for immunocompromised patients with fungal infections
• Effective against parasitic infections like leishmaniasis

How to Take Amphotericin B

Amphotericin B is administered as an intravenous infusion by a healthcare professional. The dosage and duration depend on the severity of the infection and patient response. Hydration and pre-medications may be given to minimize side effects such as fever and chills.

Types of Dosage Available

• Conventional Amphotericin B Injection
• Liposomal Amphotericin B Injection
• Amphotericin B Lipid Complex Injection
• Amphotericin B Colloidal Dispersion

Side Effects of Amphotericin B

• Fever and chills
• Nausea and vomiting
• Kidney toxicity (nephrotoxicity)
• Low potassium and magnesium levels
• Headache and dizziness

• Allergic reactions (rare but severe)

Safety Advice

• Regular kidney function tests are required during treatment
• Hydration is recommended to reduce kidney toxicity
• Patients may receive pre-medications to prevent infusion-related reactions
• Avoid using Amphotericin B with other nephrotoxic drugs
• Inform your doctor if you have liver or kidney disease
