Treatment of hypophosphatemia,Total parenteral nutrition (TPN) additive,Phosphate replacement in patients with phosphate depletion
FDA-approved for treatment of infections caused by methicillin-resistant Staphylococcus aureus (MRSA) when other agents are not suitable,Off-label: used for severe staphylococcal and enterococcal infections
IV: 2.5-5 mmol phosphate/kg body weight over 24 hours; typical dose 10-30 mmol phosphate over 4-6 hours; do not exceed 60 mmol phosphate/day.
5-10 mg/kg intravenously every 8 hours. Maximum total daily dose: 30 mg/kg.
Phosphate: 3-4 hours in healthy adults; prolonged with renal impairment. Potassium: short distribution half-life (~1-1.5 hours); no true terminal half-life due to tight regulation.
3.5-4.5 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment, requiring dose adjustment.
Phosphate is freely filtered by the glomerulus and reabsorbed in the proximal tubule; excess is excreted renally. No significant hepatic metabolism.
Primarily hepatic metabolism via glucuronidation and biliary excretion; minor renal excretion.
Renal: >90% of phosphate is reabsorbed or excreted by the kidneys; potassium is primarily excreted renally. Fecal elimination accounts for <10% of total phosphate loss.
Primarily renal (unchanged drug 70-80%); biliary/fecal (15-20%); minor metabolic clearance.
Phosphate: 10-15% bound to serum proteins (albumin and immunoglobulins). Potassium: <5% protein bound.
25-30%, primarily to albumin.
Phosphate: 0.15-0.3 L/kg (primarily extracellular fluid). Potassium: 0.5-0.7 L/kg (distributes into intracellular space).
0.25-0.35 L/kg, indicating distribution primarily into extracellular fluid.
Intravenous: 100% bioavailability. Oral (not applicable for this formulation): 60-70% for phosphate salts; potassium salts >90%.
Oral: 30-40% (variable due to first-pass metabolism); IM: 80-90%; IV: 100%.
GFR <30 m L/min: initiate at 50% of standard dose and titrate based on serum phosphate and potassium levels; avoid if GFR <15 m L/min unless severe hypophosphatemia.
GFR 30-89 m L/min: Administer 5-10 mg/kg IV every 12 hours. GFR 15-29 m L/min: Administer 5-10 mg/kg IV every 24 hours. GFR <15 m L/min: Administer 5-10 mg/kg IV every 48 hours or consider alternative therapy.
No specific Child-Pugh based recommendations; use with caution in severe hepatic impairment due to potential for electrolyte disturbances.
Child-Pugh Class A: No adjustment. Child-Pugh Class B: Reduce dose by 25%. Child-Pugh Class C: Use with caution; consider 50% dose reduction.
IV: 0.5-1 mmol phosphate/kg over 12-24 hours; monitor serum phosphate and potassium closely; do not exceed 5 mmol/kg/day.
Infants and children: 10 mg/kg IV every 8 hours. Maximum daily dose: 30 mg/kg. Neonates: 10 mg/kg IV every 12 hours.
Initiate at lower end of dosing range; monitor renal function and serum electrolytes more frequently due to age-related decline in GFR.
Initiate at 5 mg/kg IV every 12 hours, with subsequent dosing based on renal function and clinical response. Monitor for neurotoxicity and nephrotoxicity.

Hyperphosphatemia, especially in renal impairment,Hypocalcemia due to precipitation with calcium,Monitor serum calcium, phosphate, and renal function,Avoid extravasation (may cause tissue necrosis),Not for IV push; give as slow infusion
Hypersensitivity reactions including anaphylaxis,Hepatotoxicity,Bone marrow suppression (leukopenia, thrombocytopenia),Potential for drug interactions with agents metabolized by CYP450 isoenzymes
Hyperphosphatemia,Hypocalcemia,Renal failure (unless on dialysis),Patients with known hypersensitivity to any component
Hypersensitivity to novobiocin or any component,Severe hepatic impairment,Breastfeeding (due to potential for kernicterus in neonates)
Avoid high-phosphate foods (e.g., dairy, nuts, seeds, whole grains, cola) and high-potassium foods (e.g., bananas, oranges, potatoes, spinach) unless prescribed. Limit intake of calcium-rich foods if calcium levels are low.
Avoid grapefruit and grapefruit juice as they may increase ALBAMYCIN levels and risk of toxicity. No other significant food interactions known.
FDA Pregnancy Category C. No adequate studies in pregnant women. First trimester: risk cannot be ruled out; use only if clearly needed. Second/third trimesters: may cause hypocalcemia, electrolyte imbalances in fetus; avoid prolonged use.
Albamycin is teratogenic in animal studies; human data limited. Risk group: D. First trimester: Associated with teratogenic effects (e.g., cardiac defects) in animals; avoid unless life-threatening. Second trimester: Potential for fetal nephrotoxicity and ototoxicity. Third trimester: Risk of neonatal skeletal abnormalities and hearing loss; avoid near term. Fetal risk outweighs potential benefit.
Excretion in human milk unknown; M/P ratio not determined. Use with caution, weighing benefit against potential risk of electrolyte disturbances in the nursing infant.
Excreted in human milk; M/P ratio not reported. Potential adverse effects in nursing infants (gastrointestinal disturbance, hypersensitivity). Use with caution; consider alternative therapy. American Academy of Pediatrics suggests use with caution.
Increased plasma volume may require higher doses to achieve therapeutic levels; monitor serum electrolytes closely to avoid hyperphosphatemia or hypocalcemia. No standard dose adjustment established.
Increased renal clearance during pregnancy may reduce serum concentrations; therapeutic drug monitoring recommended. For obesity, adjust dose based on actual body weight due to increased volume of distribution. Dose reduction may be needed in renal impairment common in preeclampsia. No standard adjustment guidelines; individualize based on clinical response and serum levels.
Do not administer undiluted; must be infused via central line if concentration > 0.45% potassium phosphate. Monitor serum potassium, phosphate, calcium, and magnesium. Rate of infusion should not exceed 10 mmol/h of phosphate. Risk of hypocalcemia due to phosphate precipitation. Use with caution in renal impairment.
ALBAMYCIN is a novel antibiotic with potent activity against Gram-negative bacteria, but it requires therapeutic drug monitoring due to a narrow therapeutic index. It is primarily renally excreted; adjust dose in renal impairment (Cr Cl <30 m L/min). Monitor for ototoxicity and nephrotoxicity, especially in elderly and those on concurrent loop diuretics. Intravenous infusion must be administered over at least 60 minutes to reduce infusion-related reactions.
