What is Ambisome?
Ambisome is a potent prescription antifungal medication used to treat serious, and potentially life-threatening, systemic fungal infections. Its active ingredient is amphotericin B, which is encapsulated in a special fat globule called a liposome. This advanced delivery system, known as Liposomal Amphotericin B, allows the medication to more effectively target fungal cells throughout the body while helping to reduce the risk of severe side effects, particularly kidney damage, that can be associated with the conventional form of amphotericin B. Because of its strength and specific uses, Ambisome is typically administered in a hospital setting and is reserved for infections that are severe, widespread, or do not respond to other antifungal treatments. It is not intended for common, superficial fungal infections like athlete’s foot or thrush.
How does Ambisome work?
Ambisome works by directly attacking the structure of the fungal cells causing the infection. The medication’s active ingredient, amphotericin B, has a strong affinity for a substance called ergosterol, which is a critical component of fungal cell membranes but is not found in human cells. When Ambisome reaches a fungal cell, the amphotericin B binds to the ergosterol, creating pores or channels in the cell membrane. This damage causes the contents of the fungal cell, including vital electrolytes like potassium, to leak out, which ultimately leads to the death of the fungus and helps to resolve the infection. The liposomal formulation helps protect the body, especially the kidneys, from the drug’s effects until it reaches the site of infection, improving its safety profile.
Who is Ambisome for?
Ambisome is intended for patients diagnosed with severe, deep-seated fungal infections that are spreading throughout the body (systemic infections). It is a vital treatment for individuals whose immune systems are compromised, such as patients undergoing cancer chemotherapy, those who have had an organ transplant, or individuals living with AIDS, as they are at a higher risk for these types of infections. Ambisome is also specifically indicated for the primary treatment of visceral leishmaniasis, a serious parasitic disease. Furthermore, it is often used as an empirical therapy for patients with a persistent fever and low white blood cell counts (febrile neutropenia) when a fungal infection is strongly suspected but not yet confirmed. It is also an option for patients who cannot tolerate the toxic effects of conventional amphotericin B.
Dosage and administration
Ambisome is administered directly into a vein as an intravenous (IV) infusion, a process that is always performed by a qualified healthcare professional in a clinical or hospital setting. The medication comes as a powder that must be carefully reconstituted with sterile water and then further diluted, typically in a dextrose solution, before being slowly infused over a period of usually two hours. The specific dose a patient receives is highly individualized and is determined by a physician based on several factors, including the patient’s body weight, the type and severity of the fungal infection being treated, and the patient’s kidney function. Treatment duration varies and can last from several weeks to months depending on the patient’s response to the therapy and the nature of the infection.
Side effects
The most common side effects associated with Ambisome often occur during or shortly after the intravenous infusion. These infusion-related reactions can include fever, shaking, chills, nausea, vomiting, and headache. To minimize these effects, your healthcare provider may administer other medications before the infusion. While the liposomal formulation of Ambisome is designed to be safer for the kidneys than conventional amphotericin B, it can still cause kidney problems (nephrotoxicity), which requires regular a href=”https://www.israelpharm.com/blog/blood-tests-and-why-you-need-them/”blood tests/a to monitor function. Other potential side effects include low potassium or magnesium levels, decreased red blood cell counts (anemia), and muscle or back pain. In rare cases, a severe allergic reaction (anaphylaxis) may occur, which requires immediate medical attention.

While Ambisome is generally better tolerated than conventional amphotericin B, it can still cause side effects. Many common side effects are infusion-related and may be managed by your healthcare provider.
Common Side Effects:
- Fever, chills, and shaking
- Nausea and vomiting
- Headache
- Back and chest pain during infusion
- Shortness of breath
More Serious Side Effects:
- Kidney damage (nephrotoxicity)
- Low potassium (hypokalemia) or magnesium (hypomagnesemia)
- Anemia (low red blood cell count)
- Liver function abnormalities
- Severe allergic reactions (anaphylaxis)
Ambisome is indicated for the treatment of severe fungal infections affecting the entire body (systemic mycoses), especially in patients who cannot tolerate conventional amphotericin B. Its uses include:
- Treatment of severe systemic and/or deep fungal infections.
- Primary therapy for visceral leishmaniasis in both immunocompetent and immunocompromised patients.
- Empirical therapy for presumed fungal infections in patients with fever and a low white blood cell count (febrile neutropenia), often associated with cancer treatment.
- Treating systemic fungal infections in patients with compromised immune systems, such as those with AIDS or cancer.
