IndicationsOral: Inflammatory disorders including:Generally reserved for patients who do not respond to less toxic agents. Intravenous: Alternative to surgery in the management of patent ductus arteriosus (PDA) in premature neonates.ActionInhibits prostaglandin synthesis. In the treatment of PDA, decreased prostaglandin production allows the ductus to close.Therapeutic effectsOral: Suppression of pain and inflammation.Intravenous: Closure of PDA.PharmacokineticsAbsorption: Well absorbed after oral administration in adults, incomplete oral absorption in neonates.Distribution: Crosses the blood-brain barrier and the placenta. Enters breast milk.Protein Binding: 99%.Metabolism and Excretion: Mostly metabolized by the liver.Half-life: Neonates <2 weeks: 20 hr; >2 weeks: 11 hr; Adults: 2.6–11 hr.Time/action profile ROUTE | ONSET | PEAK | DURATION |

A single bedtime dose of 100 mg may be used. Antigout—100 mg initially, followed by 50 mg 3 times daily for relief of pain, then ↓ further.Oral (Children >2 yr) 1–2 mg/kg/day in 2–4 divided doses (not to exceed 4 mg/kg/day or 150–200 mg/day).PDA ClosureIntravenous (Neonates) Treatment—0.2 mg/kg initially, then 2 subsequent doses at 12–24 hr intervals of 0.1 mg/kg if age <48 hr at time of initial dose; 0.2 mg/kg if 2–7 days at initial dose; 0.25 mg/kg if age >7 days at initial dose Prophylaxis—0.1–0.2 mg/kg initially, then 0.1 mg/kg q 12–24 hr for 2 doses.Availability (generic available)Capsules: 25 mg, 50 mg Sustained-release capsules: 75 mg Oral suspensionfruit mint, pineapple coconut mint flavors: 25 mg/5 mL Rectal suppository: 50 mg Powder for injection: 1 mg/vial Nursing implicationsNursing assessment- Patients who have asthma, aspirin-induced allergy, and nasal polyps are at increased risk for developing hypersensitivity reactions. Monitor for rhinitis, asthma, and urticaria.
- Arthritis: Assess limitation of movement and pain—note type, location, and intensity before and 1–2 hr after administration.
- PDA: Monitor respiratory status, heart rate, BP, echocardiogram, and heart sounds routinely throughout therapy.
- Monitor intake and output. Fluid restriction is usually instituted throughout therapy.
- Lab Test Considerations: Evaluate BUN, serum creatinine, CBC, serum potassium levels, and liver function tests periodically in patients receiving prolonged therapy.
- Serum potassium, BUN, serum creatinine, AST, and ALT tests may show ↑ levels. Blood glucose concentrations may be altered. Hemoglobin and hematocrit concentrations, leukocyte and platelet counts, and CCr may be ↓.
- Urine glucose and urine protein concentrations may be ↑.
- Leukocyte and platelet count may be ↓. Bleeding time may be prolonged for several days after discontinuation.
Potential Nursing DiagnosesAcute pain (Indications) Impaired physical mobility (Indications)
Implementation- If prolonged therapy is used, dose should be reduced to the lowest level that controls symptoms.
- Oral: Administer after meals, with food, or with antacids to decrease GI irritation. Do not break, crush, or chew sustained-release capsules.
- Shake suspension before administration. Do not mix with antacid or any other liquid.
Intravenous Administration- pH: 6.0–7.5.
- Diluent: Preservative-free 0.9% NaCl or preservative-free sterile water. Reconstitute with 1 or 2 mL of diluent.Concentration: 0.5–1 mg/mL. Reconstitute immediately before use and discard any unused solution. Do not dilute further or admix. Do not administer via umbilical catheter into vessels near the superior mesenteric artery, as these can cause vasoconstriction and compromise blood flow to the intestines. Do not administer intra-arterially.
- Rate: Administer over 20–30 min. Avoid extravasation, as solution is irritating to tissues.
- Y-Site Compatibility: furosemide, insulin, nitroprusside, potassium chloride, sodium bicarbonate
- Y-Site Incompatibility: calcium gluconate, cimetidine, dobutamine, dopamine, gentamicin, levofloxacin, tobramycin, tolazoline
Patient/Family Teaching- Advise patient to take this medication with a full glass of water and to remain in an upright position for 15–30 min after administration.
- Instruct patient to take medication exactly as directed. Take missed doses as soon as remembered if not almost time for next dose. Do not double doses.
- May cause drowsiness or dizziness. Advise patient to avoid driving or other activities requiring alertness until response to medication is known.
- Caution patient to avoid the concurrent use of alcohol, aspirin, other NSAIDs, acetaminophen, or other OTC medications without consulting health care professional.
- Caution patient to wear sunscreen and protective clothing to prevent photosensitivity reactions.
- Advise patient to inform health care professional of medication regimen before treatment or surgery.
- Instruct patient to notify health care professional if rash, itching, chills, fever, muscle aches, visual disturbances, weight gain, edema, abdominal pain, black stools, or persistent headache occurs.
- PDA: Explain to parents the purpose of medication and the need for frequent monitoring.
Evaluation/Desired Outcomes- Decrease in severity of moderate pain.
- Improved joint mobility. Partial arthritic relief is usually seen within 2 wk, but maximum effectiveness may require up to 1 mo of continuous therapy. Patients who do not respond to one NSAID may respond to another.
- Successful PDA closure.
