Terminal elimination half-life approximately 24 hours (range 20–28 h), supports once-daily dosing; prolonged in severe hepatic impairment.
Terminal half-life: 24-48 hours (up to 7 days in hepatic impairment). Long half-life allows once-daily dosing.
Primarily metabolized by CYP3A4

Volume of distribution ~0.15 L/kg (range 0.12–0.18 L/kg), indicating limited extravascular distribution, predominantly confined to plasma and extracellular fluid.
4.0 L/kg (large, indicates extensive tissue binding, especially in liver, spleen, and lungs).
Oral bioavailability ~85%; unaffected by food.
Not applicable (IV only); if oral, <5% (due to poor absorption and first-pass metabolism).

5 mg/kg intravenously once daily; safety and efficacy not established in neonates.
No specific dose adjustment based on age alone; monitor renal function and adjust per renal guidelines.
No specific dose adjustment; monitor renal function and electrolyte levels due to age-related decline in renal function.
No FDA black box warning.
This drug should be used primarily for treatment of patients with progressive, potentially life-threatening fungal infections; it is not intended for treatment of non-invasive fungal infections (e.g., oral thrush, vaginal candidiasis) in patients with normal neutrophil counts.
Non-infectious pneumonitis,Infections (including opportunistic infections),Hypersensitivity reactions,Renal impairment,Metabolic effects (hyperglycemia, hyperlipidemia),Interstitial lung disease,Hemorrhagic events,Wound healing complications,Immunosuppression,Increased risk of thrombosis
Nephrotoxicity: monitor renal function closely; risk increased with concurrent nephrotoxic drugs.,Infusion-related reactions: fever, chills, rigors, hypotension, dyspnea; premedicate as needed.,Electrolyte abnormalities: hypokalemia, hypomagnesemia; monitor levels and replace.,Hepatotoxicity: monitor liver function tests.,Cardiotoxicity: arrhythmias, especially with rapid infusion or hypokalemia.,Pulmonary toxicity: acute pulmonary edema (rare), especially in patients with low ejection fraction.
Hypersensitivity to everolimus or any component of the formulation
Hypersensitivity to amphotericin B or any component of the formulation (unless condition is life-threatening and amenable only to amphotericin therapy).
Avoid grapefruit and grapefruit juice; may increase drug levels. Take with or without food, but high-fat meals may increase absorption. Avoid alcohol due to hepatotoxicity risk.
No specific food interactions. Ensure adequate hydration and electrolyte intake as directed. Avoid grapefruit juice as it may alter drug metabolism.
First trimester: Avoid use due to potential for fetal harm based on animal studies showing developmental toxicity (including cardiovascular and skeletal malformations). Second and third trimesters: Use only if maternal benefit outweighs fetal risk; may cause fetal growth restriction or oligohydramnios in off-label experience. No adequate human data.
Amphotericin B (AMPHOTEC) is classified as category B. Animal studies have not demonstrated fetal harm, but there are no adequate human studies in pregnant women. Inadvertent use during the first trimester is not associated with a significant increase in congenital anomalies. During the second and third trimesters, there is no evidence of fetal toxicity, although the drug should be used only if clearly needed due to maternal systemic fungal infection.
No human data on milk excretion or infant effects. M/P ratio unknown. Due to potential for serious adverse reactions (e.g., immunosuppression), advise against breastfeeding during treatment and for 2 weeks after last dose.
Amphotericin B is excreted into breast milk in low concentrations. The M/P ratio is unknown. It is considered compatible with breastfeeding because of poor oral bioavailability; however, caution is advised, and monitoring for infant diarrhea or thrush is recommended.
No established dose adjustment in pregnancy. Consider reduced dosing if increased clearance occurs (second trimester). Monitor drug levels if available; otherwise, adjust based on clinical response and toxicity.
Pharmacokinetic changes in pregnancy (increased volume of distribution, altered clearance) may require dose adjustment. Standard dosing is 3-5 mg/kg/day IV, but serum concentrations should be monitored to ensure therapeutic levels without excessive toxicity. Dose may need to be increased by 25-50% in the third trimester.
Monitor for QT prolongation, electrolyte abnormalities, and hepatotoxicity. Adjust dose in renal impairment (Cr Cl <30 m L/min). Avoid use with strong CYP3A4 inhibitors or inducers. Note potential for phototoxicity; advise sun avoidance.
Amphotec (amphotericin B liposomal) is the preferred formulation for invasive fungal infections due to reduced nephrotoxicity compared to deoxycholate. Monitor for infusion-related reactions (fever, rigors, hypotension) and premedicate with acetaminophen, diphenhydramine, and hydrocortisone. Requires baseline and serial renal function, electrolytes (especially potassium, magnesium), and liver function tests. Do not use with other nephrotoxic drugs if possible. Electrolyte repletion is critical.
Take exactly as prescribed; do not change dose or stop without consulting doctor.,Avoid grapefruit and grapefruit juice during treatment.,Use effective contraception during therapy and for 1 month after last dose.,Report symptoms like irregular heartbeat, fainting, severe nausea/vomiting, or yellowing of skin/eyes immediately.,Use sunscreen and protective clothing; avoid sun exposure, even through glass.
This medication treats serious fungal infections and is given intravenously in a hospital setting.,You may experience fever, chills, or shaking during the infusion; these can be managed with premedications.,Kidney function and blood electrolyte levels will be monitored regularly.,Report any signs of allergic reaction (rash, itching, difficulty breathing) or symptoms of electrolyte imbalance (muscle cramps, weakness, irregular heartbeat).,Avoid taking other medications that can harm the kidneys (e.g., certain antibiotics, NSAIDs) without consulting your doctor.

Common clinical questions about AUKELSO vs AMPHOTEC, answered by our medical review team.
AUKELSO is a Topical Antifungal that works by Selective inhibitor of the mammalian target of rapamycin (m TOR) kinase, specifically the m TORC1 complex, leading to inhibition of cell proliferation, angiogenesis, and glucose uptake.. AMPHOTEC is a Antifungal that works by Amphotericin B binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity, leading to leakage of intracellular contents and cell death.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between AUKELSO and AMPHOTEC depend on the specific clinical indication. These are agents from distinct pharmacological classes and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.
The standard adult dose of AUKELSO is: 400 mg orally twice daily with food.. The standard adult dose of AMPHOTEC is: Initial dose: 0.5 mg/kg intravenously once daily, titrated as tolerated to 5 mg/kg once daily.. Dosing should always be individualized based on indication, renal and hepatic function, age, and other patient factors.
No direct drug-drug interaction has been formally documented between AUKELSO and AMPHOTEC in current clinical databases. However, individual patient risk factors including other medications, organ function, and comorbidities should always be evaluated by a qualified healthcare provider.
The maternal-fetal safety profiles differ. AUKELSO is classified as Category C. First trimester: Avoid use due to potential for fetal harm based on animal studies showing developmental toxicity (including cardiovascular and skeletal malformations). Second and . AMPHOTEC is classified as Category C. Amphotericin B (AMPHOTEC) is classified as category B. Animal studies have not demonstrated fetal harm, but there are no adequate human studies in pregnant women. Inadvertent use d. Always consult a maternal-fetal medicine specialist before taking either drug during pregnancy or lactation.
