AmBisome: see instructions for use, side effects, price

There are countless diseases caused by fungi. Some of them, such as fungal meningitis , penicilliosis and even some cases of candidiasis can be very serious (or even fatal). In such cases, specific medications with enhanced action – such as AmBisome – are needed.

Check the indications, side effects, action and other information about this remedy:

What is the AmBisome Lipossomal drug?

AmBisome is a medicine from the United Medical laboratory and is used to treat serious infections caused by fungi susceptible to it – such as cryptococcosis , North American blastomycosis, disseminated candidiasis and mucormycosis. It has as an active ingredient Amphotericin B Liposomal, an antifungal substance.

Currently, the medication is available for use via intravenous infusion (that is, medication administered through the patient’s vein, as a “serum”).

What is AmBisome for?

According to the package insert, the drug AmBisome is indicated for the treatment of serious fungal infections . It can treat both severe opportunistic infections and endemic or systemic opportunistic infections.

Opportunistic infections are caused by microorganisms that, in people with normal immunity, are unlikely to lead to disease. However, in people with low immunity, they can cause serious and even fatal infections.

The endemic are infections that usually reach a population of a specific geographic region – featuring an endemic disease. Finally, those of the systemic type are those that do not affect only one region of the body, but that in some way affect the organism as a whole.

In some cases, the package insert also indicates that the medication can be used to treat visceral leishmaniasis, a disease caused by a parasite.

In addition, AmBisome is not recommended for treating simple fungal infections (such as in the nail, for example). In this case, much simpler and more conventional treatments can be performed.

How does Amphotericin B Liposomal work?

Amphotericin B is a substance that can act as a fungistatic (reduces the rate of growth of fungi) or as a fungicide (kills fungi). This can vary according to its concentration in body fluids and also due to the sensitivity of the fungus to the medication and / or active substance.

The package insert indicates that the medicine’s action occurs through its binding with sterols (a type of lipid) on the fungal cell membrane. In a way that alters the cell wall and allows the passage of small molecules. With that, fighting infection.

Dose: how does the bullet indicate using AmBisome?

AmBisome must be administered intravenously (infusion into a vein) and is a powdered medication used to make the solution for infusion. It is worth mentioning that each ampoule of the medicine contains 50mg of the active ingredient – Amphotericin B.

The medicine is for the exclusive use of hospitals and, therefore, must always be prepared and administered by a doctor or nurse.

The package insert reinforces that AmBisome cannot be administered by any other route, except intravenous by infusion. In addition, it should not be mixed with saline solutions, other drugs or electrolytes (minerals responsible for transporting water into cells).
