Indications
Short-term treatment of idiopathic apnea of prematurity in infants between 28 and <33 wk gestational age.

Action
Increases levels of cyclic AMP by inhibiting phosphodiesterase.
Acts as a bronchial smooth muscle relaxant.
Suggested mechanisms of action include:
» Stimulation of the respiratory center,
» Increased minute ventilation,
» Decreased threshold to hypercapnea,
» Increased response to hypercapnea,
» Increased skeletal muscle tone,
» Decreased diaphragmatic fatigue,
» Increased metabolic rate,
» Increased oxygen consumption.
Therapeutic Effect(s): Decrease in periods of apnea.

Pharmacokinetics
Absorption: IV administration results in complete bioavailability; also absorbed after oral administration.
Distribution: Rapidly distributes to the brain; CSF levels in neonates are similar to plasma levels.
Metabolism and Excretion: Mostly metabolized by the liver (cytochrome P450 1A2) enzymes; 38% converted to theophylline.
Half-life: Infants >9 mo, Children, and Adults: 5 hr; Neonates34 days.
TIME/ACTION PROFILE
| ROUTE | ONSET | PEAK | DURATION |
| IV | rapid | end of infusion | 24 hr |
| PO | rapid | 30 min2 hr | 24 hr |

Contraindication/Precautions
Contraindicated in:
Hypersensitivity.
Use Cautiously in:
History of seizure disorders;
History of cardiovascular disease;
Pedi: Increased risk of toxicity in neonates with impaired hepatic or renal function.

Adverse Reactions/Side Effects
CNS: insomnia, irritability, jitteriness, restlessness.
CV: tachycardia.
GI: NECROTIZING ENTEROCOLITIS, feeding intolerance, gastritis, GI bleeding.
GU: increased urine output.
Derm: dry skin, rash, skin breakdown.
Endo: hypoglycemia, hyperglycemia.
MS: muscle tremors, twitches.
*CAPITALS indicates life-threatening.
*italic indicates most frequent.

Interactions
Drug-Drug
Cimetidine , fluconazole , and ketoconazole ↓ metabolism (dose reduction of caffeine may be necessary).
Phenobarbital and phenytoin may ↑ caffeine metabolism (↑ doses of caffeine may be necessary).
Because caffeine is a significant metabolite of theophylline , concurrent administration is not recommended.

Route/Dosage
IV (Neonates): Loading dose20 mg/kg caffeine citrate (10 mg/kg caffeine base)..
IV, PO (Neonates): Maintenance dosestarting 24 hr after loading dose 5 mg/kg caffeine citrate (2.5 mg/kg caffeine base) q 24 hr..

Availability
Solution for injection: 20 mg/mL caffeine citrate (10 mg/mL caffeine base) in 3-mL vials
Oral solution: 20 mg/mL caffeine citrate (10 mg/mL caffeine base) in 3-mL vials

Assessment
Assess respiratory status frequently throughout therapy.
Monitor patient for signs of necrotizing enterocolitis (abdominal distension, vomiting, bloody stools, lethargy). May be fatal.
Lab Test Considerations
Monitor serum caffeine levels before and periodically during therapy in infants previously treated with theophylline or in infants whose mothers consumed caffeine before delivery.
» Monitor serum glucose levels. May cause hypoglycemia or hyperglycemia.
Therapeutic range: 820 mcg/mL.
Toxicity and Overdose Serum caffeine levels of >50 mcg/mL have been associated with serious toxicity. Monitor serum levels and adjust dose in neonates with impaired hepatic or renal function to avoid toxicity.

Implementation
PO: Maintenance doses may also be administered orally.
IV Adminstration:
pH:
4.7.
Intermittent Infusion:
Solution should be clear, without particulate matter.
Rate:
Initial loading dose should be administered over 30 min. Maintenance doses may be administered over 10 min every 24 hr beginning 24 hr after loading dose. Syringe pump should be used to ensure accurate delivery.

Patient/Family Teaching
Instruct parent on correct technique for administration. Measure oral dose accurately with a 1-mL syringe. If apnea events continue, consult health care professional; do not increase dose.
Advise parent to consult health care professional immediately if signs of necrotizing enterocolitis occur.

Evaluation/Desired Outcomes
Decrease in apneic episodes in premature infant.
