1 drop in each eye twice daily (morning and evening) as ophthalmic solution.
Loading dose: 5-6 mg/kg IV over 20-30 minutes, then continuous infusion: 0.5-0.7 mg/kg/hour IV.
Terminal elimination half-life is approximately 20-24 hours; allows once-daily dosing in most patients, but may be prolonged in renal impairment.
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.
Not applicable; active ingredients are present in extremely low concentrations (typically 6X to 30X potency) and are not expected to undergo significant systemic metabolism.
Hepatic via cytochrome P450 enzymes (CYP1A2, CYP3A4, CYP2E1); saturable kinetics; extensive first-pass metabolism.
Renal excretion of unchanged drug and metabolites accounts for >90% of elimination; biliary/fecal excretion is minor (<10%).
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.
Plasma protein binding is approximately 99%, primarily to albumin.
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.
Volume of distribution is 0.1-0.3 L/kg, indicating minimal extravascular distribution and high intravascular retention.
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).
Oral bioavailability is 90-100%, consistent with nearly complete absorption.
Oral immediate-release: 100% (well absorbed). Rectal: 80-100% (absorption may be erratic). IV: 100%. No significant first-pass metabolism.
No dosage adjustment required for renal impairment; however, use caution in severe renal disease (Cr Cl <30 m L/min) due to potential systemic absorption.
No specific dose adjustment required for GFR >10 m L/min. For GFR <10 m L/min, reduce infusion rate by 50%.
No formal studies in hepatic impairment; use caution in Child-Pugh class C (severe) due to possible increased systemic exposure.
Child-Pugh Class A: reduce dose by 25%; Class B: reduce dose by 50%; Class C: reduce dose by 75%.
Safety and efficacy not established; use not recommended in pediatric patients under 18 years.
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).
No specific dose adjustment; monitor for increased intraocular pressure or systemic effects due to potential age-related changes in clearance.
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.
None
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).
Do not use if solution changes color or becomes cloudy. Do not touch dropper tip to any surface to avoid contamination. Contact lens wearers should remove lenses before instillation and wait 10 minutes before reinserting. If symptoms persist or worsen, consult a physician.
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
Known hypersensitivity to any component. Not for use in patients with acute eye infection, glaucoma, or other serious eye conditions.
Hypersensitivity to aminophylline or any component,Hypersensitivity to theophylline or ethylenediamine,Cardiac arrhythmias requiring immediate therapy (relative)
No specific food interactions known for ophthalmic ketorolac. However, systemic NSAIDs can interact with alcohol (increased GI bleeding risk), but this is negligible with ocular use.
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.
No adequate studies in pregnant women. Animal studies not available. Risk cannot be ruled out. Use only if potential benefit justifies risk.
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.
Unknown if excreted in human milk. Caution advised. M/P ratio not available.
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.
No dose adjustment recommendations due to lack of data.
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.
Ocuclear (ketorolac tromethamine ophthalmic solution) is a nonsteroidal anti-inflammatory drug (NSAID) used for ocular inflammation. Use with caution in patients with bleeding disorders or those on anticoagulants due to increased risk of ocular bleeding. Monitor for corneal epithelial effects with prolonged use. Contraindicated in patients with aspirin allergy or NSAID hypersensitivity.
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.

No interactions on record
"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."
