AmBisome should be administered by intravenous infusion over a 30 – 60 minute period. For doses greater than 5mg/kg/day, intravenous infusion over a 2 hour period is recommended (see section 4.4). The recommended concentration for intravenous infusion is 0.20 mg/ml to 2.00 mg/ml amphotericin B as AmBisome.

What happens if AmBisome is mixed with saline?
Example of the preparation of AmBisome solution for infusion at a dose of 10mg/kg/day in dextrose solution for infusion. – The Ambisome should NEVER be mixed with Normal Saline or Half Normal Saline as it will precipitate. The line that is used for Ambisome should not be used for administering any other drugs.
How do you dissolve amphotericin B?
Amphotericin B is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, amphotericin Bshould first be dissolved in DMSO and then diluted with the aqueous buffer of choice. Amphotericin B has a solubility of approximately 0.5 mg/ml in a 1:1 solution of DMSO:PBS (pH 7.2) using this method.
Can amphotericin B be given in normal saline?
– The Amphotericin B should NEVER be mixed with Normal Saline or Half Normal Saline as it will precipitate. The line that is used for Amphotericin-B should not be used for administering any other drugs.
Why is amphotericin B mixed with dextrose?
Amphotericin B diluted in a lipid emulsion seems to be associated with a smaller number of acute adverse events and fewer cases of hypokalemia than amphotericin B diluted in 5% dextrose. Amphotericin B is considered the drug of choice for the treatment of systemic fungal infections.
Does AmBisome need to be refrigerated?
Prior to reconstitution Amphotericin B for Injection USP should be stored under refrigeration, 2° to 8°C (36°to 46°F), protected against exposure to light.

Outpatient use: When used for inhalation, this may be stored for up to 7 days between 2 and 8˚C if protected from light and may be used for the subsequent dose.
How do you dilute amphotericin?
Dilute each ‘mg’ of drug with 10 ml. [1 mg/ 10 ml ] [4 – 6 hours] * dilute the reconstituted solution with 250-500 mL D5W; final concentration should not exceed 0.1 mg/mL (peripheral infusion) or 0.25 mg/mL (central infusion). Add 10 mL of SWFI (without a bacteriostatic agent) to each vial of amphotericin B.
Is amphotericin B soluble in water?
Amphotericin B is insoluble in water at pH 6 to 7, but soluble in water at pH 2 or 11. It is soluble in DMSO (30–40 mg/ml) and in dimethylformamide (2–4 mg/ml). Aqueous solutions cannot be sterile filtered due to poor solubility.

What is the difference between amphotericin B and AmBisome?
These results suggest that AmBisome® is an effective and safe antifungal agent in the treatment of systemic candidiasis in VLBWI. The mean duration of AmBisome® therapy was shorter than amphotericin B therapy, but fungal eradication rates, eradication time, and mortality rates were similar.
Why is amphotericin B diluted in Dextrose?
Why is amphotericin B so toxic to humans?
Because mammalian and fungal membranes are similar in structure and composition, this is one mechanism by which amphotericin B causes cellular toxicity. Amphotericin B molecules can form pores in the host membrane as well as the fungal membrane. This impairment in membrane barrier function can have lethal effects.
Is AmBisome a biologic?
