Intravenous infusion. Adult: 500-1000 m L per dose at a rate of 2-6 m L/min, frequency dependent on fluid and electrolyte needs. Maximum 40 m L/kg/day.
Loading dose: 5-6 mg/kg IV over 20-30 minutes, then continuous infusion: 0.5-0.7 mg/kg/hour IV.
Glucose half-life is approximately 1.5-2 hours in normal individuals, prolonged in renal impairment or diabetes. Sodium and chloride have no defined half-life as they are electrolytes; their elimination depends on renal function and hydration status.
Terminal elimination half-life is 6-12 hours in adults, 1-5 hours in children (due to faster clearance), 20-30 hours in premature neonates, and 10-15 hours in patients with hepatic cirrhosis or heart failure. Clinical context: dosing interval adjustment required based on half-life; prolonged half-life in hepatic impairment or cardiac decompensation increases risk of toxicity.
Dextrose is metabolized via glycolysis and the citric acid cycle; insulin-dependent uptake. Sodium chloride is not metabolized; excreted renally.
Hepatic via cytochrome P450 enzymes (CYP1A2, CYP3A4, CYP2E1); saturable kinetics; extensive first-pass metabolism.
Renal: >99% of administered glucose is metabolized or excreted; sodium and chloride are excreted renally. In dextrose 5% and sodium chloride 0.2%, glucose undergoes metabolism to CO2 and water; excess is excreted renally. Sodium and chloride are almost entirely excreted renally with >90% reabsorption under normal conditions.
Renal excretion of unchanged theophylline (10-20%) and metabolites (80-90%). In neonates, renal excretion of unchanged drug is higher (up to 50%). Biliary/fecal excretion is negligible.
Glucose: negligible (<1%). Sodium and chloride: not protein bound.
Approximately 40% bound to plasma proteins, mainly albumin. In neonates, preterm infants, and patients with hepatic cirrhosis, protein binding is reduced (free fraction increases). Binding is also saturable at high theophylline concentrations.
Glucose: approximately 0.2-0.25 L/kg; distributes primarily in extracellular fluid. Sodium: 0.6-0.7 L/kg (total body water); chloride: similar. Clinical meaning: initial distribution reflects ECF volume; changes indicate fluid shifts.
Volume of distribution is approximately 0.45 L/kg (range 0.3-0.7 L/kg) in adults. In neonates, Vd is larger (~0.6-0.8 L/kg). Clinical meaning: Vd indicates extensive distribution into body water; loading doses are calculated using Vd (e.g., 1 mg/kg raises serum concentration by ~2 mcg/m L).
Intravenous: 100% for all components. Not applicable for oral or other routes as this formulation is for IV use only.
Oral immediate-release: 100% (well absorbed). Rectal: 80-100% (absorption may be erratic). IV: 100%. No significant first-pass metabolism.
For GFR 30-50 m L/min: close monitoring of electrolytes; GFR <30 m L/min: use with caution, monitor for hypernatremia and fluid overload, reduce infusion rate by 50%.
No specific dose adjustment required for GFR >10 m L/min. For GFR <10 m L/min, reduce infusion rate by 50%.
No specific adjustment required for Child-Pugh class A or B; use with caution in class C due to risk of fluid overload.
Child-Pugh Class A: reduce dose by 25%; Class B: reduce dose by 50%; Class C: reduce dose by 75%.
Intravenous infusion. 5-10 m L/kg per dose as needed; rate not to exceed 0.5-1 g/kg/hour of dextrose. For neonates, avoid unless specific indication due to high sodium load.
Loading dose: 5-6 mg/kg IV over 20-30 minutes; continuous infusion: 0.5-0.7 mg/kg/hour (age-dependent, with lower doses for younger children).
Reduce initial infusion rate to 1-2 m L/min due to decreased renal function and higher risk of fluid overload; monitor serum sodium and osmolality closely.
Elderly patients may have reduced clearance; consider starting at the lower end of dosing range (e.g., 0.3-0.5 mg/kg/hour) and titrate based on serum levels.
Solutions containing dextrose may be contraindicated in patients with known allergies to corn or corn products. Intrathecal administration is contraindicated.
Theophylline toxicity is dose-related and can be fatal; monitor serum theophylline levels closely; use with caution in patients with risk factors for reduced clearance (e.g., hepatic impairment, heart failure, elderly).
Risk of hyperglycemia and hyperosmolar syndrome, especially in patients with diabetes mellitus,May cause fluid and solute overload leading to dilution of serum electrolytes, overhydration, congested states, or pulmonary edema,Use with caution in patients with heart failure, renal impairment, or severe dehydration,Not for use in patients with intracranial or intraspinal hemorrhage,Air embolism risk if administered via pressurized IV lines
Narrow therapeutic index; severe toxicity can occur at levels >20 mcg/m L,Seizures and arrhythmias may occur without preceding symptoms,Variable clearance due to drug interactions, disease states, age, and smoking,Use with caution in peptic ulcer disease, seizure disorders, hyperthyroidism, and cardiac disease
Hyperglycemia and hyperosmolar coma,Hypersensitivity to corn or corn products,Intrathecal administration,Severe dehydration with hypernatremia,Addison's disease without adequate corticosteroid therapy
Hypersensitivity to aminophylline or any component,Hypersensitivity to theophylline or ethylenediamine,Cardiac arrhythmias requiring immediate therapy (relative)
No specific food interactions. Monitor fluid and electrolyte balance especially if patient is on a low-sodium diet. Dextrose may affect blood glucose; adjust meal timing or insulin accordingly.
Avoid high-dose caffeine (coffee, tea, energy drinks, chocolate) as it may increase risk of side effects like nausea, anxiety, and tachycardia. Charcoal-broiled foods and a high-protein diet may increase theophylline clearance. Consistent dietary intake is recommended.
Dextrose and sodium chloride are physiologic substances. No teratogenic risk is reported; however, hyperglycemia or electrolyte imbalances in the mother may affect the fetus. Use standard precautions.
First trimester: Limited data; no increased risk of major malformations observed in human studies. Second and third trimesters: Risk of fetal tachycardia and jitteriness with high maternal doses; may cause transient neonatal tachycardia with chronic use. No documented teratogenicity.
Dextrose and sodium chloride are normal blood constituents; transfer into breast milk is not clinically significant. No M/P ratio available; considered safe during breastfeeding.
Aminophylline/theophylline is excreted into breast milk with an M/P ratio of approximately 0.6-0.7. Infant exposure is low (about 1-10% of maternal dose). Irritability and insomnia reported rarely. Use with caution, monitor infant for signs of theophylline toxicity.
Total body water increases in pregnancy, potentially expanding distribution volume; however, dosing is based on clinical status. Monitor for fluid overload and electrolyte disturbances. No specific dose adjustment is required for standard maintenance infusions.
Pregnancy decreases theophylline clearance by approximately 20-30% during third trimester. Dosing adjustments may be required: monitor serum levels and adjust dose to maintain therapeutic levels. Postpartum clearance returns rapidly, requiring downward dose adjustment.
This isotonic solution provides 170 kcal/L from dextrose and is used for maintenance hydration and electrolyte replacement. Monitor serum glucose in diabetics; may cause hyperglycemia. Contains 34 m Eq/L sodium and 34 m Eq/L chloride. Avoid in patients with hypernatremia, fluid overload, or significant renal impairment. Use with caution in pediatric and elderly patients due to risk of hyponatremia.
Aminophylline is a bronchodilator that releases theophylline. Monitor serum theophylline levels (therapeutic range 5-15 mcg/m L). Avoid in patients with active peptic ulcer disease, seizure disorders, or hypersensitivity to xanthines. Caution in hepatic impairment, heart failure, and elderly due to reduced clearance. Drug interactions with cimetidine, ciprofloxacin, and macrolides increase theophylline levels.

"Lithium cation may increase the excretion rate of Sodium chloride which could result in a lower serum level and potentially a reduction in efficacy."
"The risk or severity of adverse effects can be increased when Sodium chloride is combined with Tolvaptan."
"Concurrent administration of aminophylline, a xanthine derivative bronchodilator that is metabolized primarily by CYP1A2 and to a lesser extent CYP3A4, may reduce the clearance of ranolazine, an antianginal agent predominantly metabolized by CYP3A4 and to a lesser extent CYP2D6. Aminophylline can inhibit CYP3A4 activity, leading to increased ranolazine plasma concentrations, which elevates the risk of dose-dependent adverse effects such as QTc prolongation, dizziness, and syncope. This interaction is clinically significant and may necessitate dose adjustment or alternative therapy."
"Asunaprevir, a potent inhibitor of the drug transporter OATP1B1, can significantly decrease the serum concentration of aminophylline, a theophylline salt, likely by reducing its intestinal absorption or increasing its hepatic clearance. This interaction may lead to reduced therapeutic efficacy of aminophylline, potentially worsening respiratory symptoms in patients with asthma or COPD. Close monitoring and dose adjustment of aminophylline are recommended during coadministration with asunaprevir."
"Aminophylline, a bronchodilator, inhibits the metabolism of tibolone, a synthetic steroid hormone used for hormone replacement therapy, primarily through competitive inhibition of cytochrome P450 (CYP) 3A4 isoenzyme. This results in increased plasma concentrations of tibolone and its active metabolites, potentiating its hormonal effects and increasing the risk of adverse events such as thromboembolism, endometrial hyperplasia, or breast tenderness. Clinically, coadministration may require dose adjustments and careful monitoring for signs of estrogenic excess."
