🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Amphotericin B binds to ergosterol, a key component of the fungal cell membrane. This binding creates pores or channels in the membrane, leading to leakage of intracellular ions and molecules, which results in fungal cell death. Because human cell membranes contain cholesterol instead of ergosterol, the medicine has some selectivity for fungal cells, but it can still cause toxicity in human cells, particularly in the kidneys.
Mechanism Steps
💡 How to Take amtericin 50mg injection
Strength: Lyophilized powder for injection, 50mg per vial.
Dosage Information
| Adult Dosage | The usual adult dose ranges from 0.25 to 1.5 mg/kg per day, depending on the type and severity of the fungal infection. For invasive aspergillosis, a dose of 0.5 to 1.5 mg/kg per day is common. For cryptococcal meningitis, 0.7 to 1 mg/kg per day is often used. The drug is administered as a slow intravenous infusion over 2 to 6 hours. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function, and tolerability. Premedication and hydration are often required. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing. |
| Elderly Dosage | Elderly patients may be more susceptible to kidney toxicity and electrolyte imbalances. Dose should be individualized by a qualified clinician based on renal function and overall health status. Close monitoring is recommended. |
| Renal Impairment | In patients with pre-existing renal impairment, the dose may need to be reduced or the interval extended. Monitor kidney function closely and adjust dose as needed. Dose must be individualized by a qualified clinician. |
| Hepatic Impairment | No specific dose adjustments are established for hepatic impairment. Use with caution and monitor liver function. Dose must be individualized by a qualified clinician. |
| Maximum Daily Dose | The maximum daily dose is not firmly established and depends on the indication and patient factors. Doses up to 1.5 mg/kg per day have been used. Dose must be individualized by a qualified clinician. |
