🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Liposomal amphotericin B works by binding to ergosterol, a key component of the fungal cell membrane. This binding creates pores or channels in the membrane, leading to leakage of essential intracellular contents such as potassium and other ions, which ultimately causes fungal cell death. The liposomal formulation delivers the drug preferentially to fungal cells and reduces its interaction with human cholesterol, thereby lowering kidney toxicity compared to conventional amphotericin B deoxycholate.

Dosage Information
| Adult Dosage | The dose of this medicine is individualized by a qualified clinician based on the type and severity of the fungal infection, the patient's kidney function, and other factors. For invasive aspergillosis, a typical starting dose is 3 to 5 mg/kg per day given as a single intravenous infusion. For cryptococcal meningitis, doses may range from 3 to 6 mg/kg per day. For empirical therapy in febrile neutropenia, 3 mg/kg per day is common. Doses may be adjusted based on clinical response and toxicity. Always follow your healthcare provider's instructions. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. Doses are individualized based on weight, indication, and clinical status. |
| Elderly Dosage | Elderly patients may be more susceptible to kidney damage and electrolyte imbalances. Doses should be individualized by a clinician, and kidney function should be monitored closely. |
| Renal Impairment | Dose adjustment may be necessary in patients with kidney impairment. The liposomal formulation is less nephrotoxic than conventional amphotericin B, but caution is still required. Monitor kidney function closely and adjust dose as needed. |
| Hepatic Impairment | No specific dose adjustment guidelines are established for hepatic impairment. Use with caution and monitor liver function. |
| Maximum Daily Dose | The maximum daily dose is not fixed and depends on the indication and patient factors. Doses up to 10 mg/kg per day have been used in some severe infections under close supervision. Always follow the prescribed dose. |
