AmBisome (liposomal amphotericin B) | Infectious Diseases Management Even after I double checked the info in the link that I provided above that states NAHCo3 is compatibile with NS, you still made me second guess myself, so I called the pharmacist at the hospital. Amphotericin B has a molecular formula of C47H73NO17 and a molecular weight of 924.08 g/mol. Amphotericin B-induced hypokalemia may enhance the curariform effect of skeletal muscle relaxants (e.g. Amphotericin B liposome for injection is pale yellow to yellow lyophilized product, available as single cartons. Azoles (e.g., ketoconazole, miconazole, clotrimazole, fluconazole, etc.) The use of any solution other than those recommended, or the presence of a bacteriostatic agent in the solution, may cause precipitation of Amphotericin B liposome for injection. Biacarb drips are always mixed with D5W, never NS. 1998 Jan-Feb;25(1):35-48. [58] After cyclisation, the macrolactone core undergoes further modification by hydroxylation, methylation and glycosylation. Efficacy is expressed as both acute parasite clearance at the end of therapy (EOT) and as overall success (clearance with no relapse) during the follow-up period (F/U) of greater than 6 months for immunocompetent and immunocompromised patients: When followed for 6 months or more after treatment, the overall success rate among immunocompetent patients was 96.5% and the overall success rate among immunocompromised patients was 11.8% due to relapse in the majority of patients. Aseptically add 12 mL of Sterile Water for Injection, USP to each AmBisome vial to yield a preparation containing 4 mg amphotericin B/mL. [7][8] It is on the World Health Organization's List of Essential Medicines. [45], In addition, electrolyte imbalances such as hypokalemia and hypomagnesemia are also common. Other Nephrotoxic Medications Before taking this medicine Hemic & Lymphatic System When administered concomitantly with ABELCET, serum potassium levels should be closely monitored. Never had any problems. Or is it just incompatible to mix it in a NS minibag??? Create well-written care plans that meets your patient's health goals. Due to the nature and quantity of amphophilic substances used, and the lipophilic moiety in the Amphotericin B molecule, the drug is an integral part of the overall structure of the Amphotericin B liposome for injection liposomes. The manufacturer recommends beginning intravenous therapy with a 1-mg test dose. Intravenous admixtures of amphotericin B 0.25 and 1.4 mg/mL in 5% dextrose injection have an expiration date of 35 days and 36 hours, respectively. Combination therapy should be administered with caution, especially in immunocompromised patients. Do not use amphotericin B in larger amounts than recommended. Amphotericin B is capable of forming channels in membranes. Prior assessments varied from 3.75 mg/kg body weight to 15 mg/kg, with 89100% shown efficacy. Amphotericin B was studied in patients with visceral leishmaniasis who were infected in the Mediterranean basin with documented or presumed Leishmania infantum. Amphotericin B, the active ingredient of Amphotericin B liposome for injection, acts by binding to the sterol component, ergosterol, of the cell membrane of susceptible fungi. Success rates at 10 weeks in patients with positive baseline culture for cryptococcus species are summarized in the following table and show that the efficacy of Amphotericin B liposome for injection 6 mg/kg/day approximates the efficacy of the Amphotericin B deoxycholate regimen. [48][49] It has been found that the amphotericin B/ergosterol bimolecular complex that maintains these pores is stabilized by Van der Waals interactions. However, based on total Amphotericin B concentration measured up to 49 days after dosing of Amphotericin B liposome for injection, the mean half-life was 100 to 153 hours.
