Contraindications

Hypersensitivity to theophylline, ethylenediamine, or any component of the formulation

Canadian labeling: Additional contraindications (not in U.S. labeling): Coronary artery disease where cardiac stimulation might prove harmful; patients with peptic ulcer disease

Warnings/Precautions

Concerns related to adverse effects:

• Theophylline toxicity: If a patient develops signs and symptoms of theophylline toxicity (eg, persistent, repetitive vomiting), a serum level should be measured and subsequent doses held. Theophylline clearance may be decreased in patients with acute pulmonary edema, congestive heart failure, cor pulmonale, fever, hepatic disease, acute hepatitis, cirrhosis, hypothyroidism, sepsis with multiorgan failure, and shock; clearance may also be decreased in neonates, infants <3 months of age with decreased renal function, children <1 year of age, the elderly >60 years, and patients following cessation of smoking.

Disease-related concerns:

• Cardiovascular disease: Use with caution in patients with hypertension or cardiac arrhythmias (excluding bradyarrhythmias).

• Hyperthyroidism: Use with caution in patients with hyperthyroidism.

• Peptic ulcer disease: Use with caution in patient with peptic ulcer disease (use is contraindicated in the Canadian labeling).

• Seizure disorder: Use with caution in patients with a history of seizure disorder.

Other warnings/precautions:

• Dosage adjustments: Due to potential saturation of theophylline clearance at serum levels within (or in some patients less than) the therapeutic range, dosage adjustment should be made in small increments (maximum: 25% dose increase).

• Monitoring: Due to wide interpatient variability, theophylline serum level measurements must be used to optimize therapy and prevent serious toxicity.

Mechanism of Action

Causes bronchodilatation, diuresis, CNS and cardiac stimulation, and gastric acid secretion by blocking phosphodiesterase which increases tissue concentrations of cyclic adenine monophosphate (cAMP) which in turn promote catecholamine stimulation of lipolysis, glycogenolysis, and gluconeogenesis and induce release of epinephrine from adrenal medulla cells

Pharmacodynamics/Kinetics

Theophylline:

Absorption: Oral: Immediate release tablet: Rapid and complete

Distribution: 0.45 L/kg based on ideal body weight

Protein binding: 40%, primarily to albumin

Metabolism: Children >1 year and Adults: Hepatic; involves CYP1A2, 2E1, and 3A4; forms active metabolites (caffeine and 3-methylxanthine)

I.V.: Within 30 minutes

Excretion: Children >3 months and Adults: Urine (10% as unchanged drug)

Dosage

Note: Doses should be individualized based on peak serum concentrations and should be based on ideal body weight. Theophylline dose is 80% of aminophylline dose.

Acute symptoms: Loading dose: Oral, I.V.:

Patients not currently receiving aminophylline or theophylline: Aminophylline 5.7 mg/kg (equivalent to theophylline 4.6 mg/kg) administered I.V. or theophylline 5 mg/kg administered orally

Patients currently receiving aminophylline or theophylline: A loading dose is not recommended without first obtaining a serum theophylline concentration in patients who have received aminophylline or theophylline within the past 24 hours. The loading dose should be calculated as follows:

Dose = (desired serum theophylline concentration - measured serum theophylline concentration) (Vd)

Acute symptoms: Maintenance dose: I.V.: Note: To achieve a target theophylline concentration of 10 mcg/mL unless otherwise noted. Lower initial doses may be required in patients with reduced theophylline clearance. Dosage should be adjusted according to serum level measurements during the first 12- to 24-hour period.

Infants 6-52 weeks: Equivalent theophylline dose: mg/kg/hour = (0.008) (age in weeks) + 0.21

Children 1-9 years: 1.01 mg/kg/hour (equivalent to theophylline 0.8 mg/kg/hour)

Children 9-12 years: 0.89 mg/kg/hour (equivalent to theophylline 0.7 mg/kg/hour)

Adolescents 12-16 years (cigarette or marijuana smokers): 0.89 mg/kg/hour (equivalent to theophylline 0.7 mg/kg/hour)

Adolescents 12-16 years (nonsmokers): 0.63 mg/kg/hour (equivalent to theophylline 0.5 mg/kg/hour); maximum: 900 mg/day unless serum levels indicate need for larger dose

Adults 16-60 years (otherwise healthy, nonsmokers): 0.51 mg/kg/hour (equivalent to theophylline 0.4 mg/kg/hour); maximum: 900 mg/day unless serum levels indicate need for larger dose

Adults >60 years: 0.38 mg/kg/hour (equivalent to theophylline 0.3 mg/kg/hour); maximum: 400 mg/day unless serum levels indicate need for larger dose

Dosage adjustment for cardiac decompensation, cor pulmonale, hepatic dysfunction, sepsis with multiorgan failure, shock: 0.25 mg/kg hour (equivalent to theophylline 0.2 mg/kg/hour); maximum: 400 mg/day unless serum levels indicate need for larger dose

Dosage adjustment after serum theophylline measurement:

Within normal limits: Asthma: 5-15 mcg/mL: Maintain dosage if tolerated. Recheck serum theophylline concentration at 24-hour intervals (for acute I.V. dosing) or at 6- to 12-month intervals (for oral dosing). Finer adjustments in dosage may be needed for some patients. If levels ≥15 mcg/mL, consider 10% dose reduction to improve safety margin.

Too high:

20-24.9 mcg/mL: Decrease dose by ~25%. Recheck serum theophylline concentrations (see "Note").

25-30 mcg/mL: Skip next dose (oral) or stop infusion for 12 hours (children) or 24 hours (adults) and decrease subsequent doses by ~25%. Recheck serum theophylline concentrations (see "Note").

>30 mcg/mL: Stop dosing and treat overdose; if resumed, decrease subsequent doses by 50%. Recheck serum theophylline concentrations (see "Note").

Too low: <9.9 mcg/mL: If tolerated, but symptoms remain, increase dose by ~25%. Recheck serum theophylline concentrations (see "Note").

Note: Recheck serum theophylline levels after 3 days when using oral dosing, or after 12 hours (children) or 24 hours (adults) when dosing intravenously. Patients maintained with oral therapy may be reassessed at 6- to 12-month intervals.

Chronic conditions: Oral:

Immediate release tablets: Note: Increase dose only if tolerated. Consider lowering dose or using a slower titration if caffeine-like adverse events occur. Smaller doses given more frequently may be used in patients with a more rapid metabolism to prevent breakthrough symptoms which could occur due to low trough concentration prior to the next dose.

Children 1-15 years and <45 kg without risk factors for impaired theophylline clearance:

Aminophylline 15.2-17.7 mg/kg/day (equivalent to theophylline 12-14 mg/kg/day) in divided doses every 4-6 hours for 3 days (maximum daily dose: aminophylline 380 mg/day, equivalent to theophylline 300 mg/day);

Then increase to 20.3 mg/kg/day (equivalent to theophylline 16 mg/kg/day) in divided doses every 4-6 hours for 3 days (maximum dose: aminophylline 507 mg/day, equivalent to theophylline 400 mg/day)

Maintenance dose: 25.3 mg/kg/day (equivalent to theophylline 20 mg/kg/day) in divided doses every 4-6 hours (maximum dose: aminophylline 760 mg/day, equivalent to theophylline 600 mg/day)

Note: Dose adjustment in patients with risk factors for impaired theophylline clearance and patients in whom monitoring serum theophylline levels is not feasible: Do not exceed a dose of aminophylline 20.3 mg/kg/day (equivalent to theophylline 16 mg/kg/day). (Maximum dose: Aminophylline 507 mg/day, equivalent to theophylline 400 mg/day)

Children >45 kg and Adults 16-60 years without risk factors for impaired theophylline clearance:

Aminophylline 380 mg/day (equivalent to theophylline 300 mg/day) in divided doses every 6-8 hours for 3 days;

Then increase to 507 mg/day (equivalent to theophylline 400 mg/day) in divided doses every 6-8 hours for 3 days

Maintenance dose: 760 mg/day (equivalent to theophylline 600 mg/day) in divided doses every 6-8 hours

Note: Dose adjustment in patients with risk factors for impaired theophylline clearance and patients in whom monitoring serum theophylline levels is not feasible: Do not exceed a dose of aminophylline 507 mg/day (equivalent to theophylline 400 mg/day)

Adults >60 years: Refer to adult dosing. Do not exceed a dose of aminophylline 507 mg/day (equivalent to theophylline 400 mg/day)

Sustained release tablets: Canadian labeling: Children ≥12 years and Adults: Initial: 1 tablet (225-350 mg) every 12 hours (equivalent to theophylline 182.25-283.5 mg every 12 hours); may increase dose by 1/2 tablet per dose at 3- to 4-day intervals; maximum dose: 1125 mg/day (equivalent to theophylline 900 mg/day); do not exceed maximum dose without monitoring theophylline concentrations.

Reversal of adenosine-, dipyridamole-, or regadenoson-induced adverse reactions (eg, angina, hypotension) during nuclear cardiac stress testing (unlabeled use): Adults: I.V.: 50-250 mg administered over 30-60 seconds, repeat as necessary. Note: Since adenosine-induced side effects are short lived after discontinuation of the infusion, aminophylline administration is only very rarely required.

Administration: Oral

Tablet, immediate release: If dose is missed, administer the next dose at the scheduled time (do not make up missed dose).

Tablet, sustained release (Canadian labeling, not available in the U.S.): Administer every 12 hours with a full glass of water. Patient should be in the standing or sitting position. Tablets may be halved, however do not crush, chew or dissolve. Evening dose should be administered with or shortly following the evening meal. May administer a missed dose if within 4 hours of scheduled dosing time.

Administration: I.M.

Not recommended

Administration: I.V.

Loading doses should be administered I.V. over 30 minutes. Infusion rate should not exceed 21 mg/hour (equivalent to theophylline 17 mg/hour) in patients with cor pulmonale, cardiac decompensation, liver dysfunction, patients >60 years, or patients taking medications which reduce theophylline clearance.

For reversal of adenosine-, dipyridamole-, or regadenoson-induced adverse events during nuclear cardiac stress testing, administer I.V. undiluted over 30-60 seconds, repeat as necessary. Since adenosine-induced side effects are short lived after discontinuation of the infusion, aminophylline administration is only very rarely required.

Monitoring Parameters

Monitor heart rate; CNS effects (insomnia, irritability); respiratory rate (COPD patients often have resting controlled respiratory rates in low 20s); arterial or capillary blood gases (if applicable)

Theophylline levels: Serum theophylline levels should be monitored prior to making dose increases; in the presence of signs or symptoms of toxicity; or when a new illness, worsening of a present illness, or medication changes occur that may change theophylline clearance

I.V. loading dose: Measure serum concentrations 30 minutes after the end of an I.V. loading dose

I.V. infusion: Measure serum concentrations one half-life after starting a continuous infusion, then every 12-24 hours

Reference Range

Therapeutic levels: Asthma: 5-15 mcg/mL (peak level)

Toxic concentration: >20 mcg/mL

Test Interactions

Plasma glucose, uric acid, free fatty acids, total cholesterol, HDL, HDL/LDL ratio, and urinary free cortisol excretion may be increased by theophylline. Theophylline may decrease triiodothyronine.

Geriatric Considerations

Although there is a great intersubject variability for half-lives of methylxanthines (2-10 hours), elderly, as a group, have slower hepatic clearance. Therefore, use lower initial doses and monitor closely for response and adverse reactions. Additionally, elderly patients are at greater risk for toxicity due to concomitant disease (eg, congestive heart failure, arrhythmias), and drug use (eg, cimetidine, ciprofloxacin, etc).

Additional Information

Aminophylline is a 2:1 complex of theophylline and ethylenediamine.

Cardiovascular Considerations

Theophylline results in significant tachycardia and, at higher doses, may impair ventricular rate control in patients with atrial fibrillation. This is particularly a concern since patients with underlying chronic obstructive lung disease often have coexisting atrial fibrillation. Aminophylline can be used to treat patients who have adverse hemodynamic responses to adenosine, dipyridamole or regadenoson, when used during cardiovascular stress testing. Since adenosine-induced side effects are short lived after discontinuation of the infusion, aminophylline administration is only very rarely required.

Dental Health: Effects on Dental Treatment

Prescribe erythromycin products with caution to patients taking theophylline products. Erythromycin will delay the normal metabolic inactivation of theophyllines leading to increased blood levels; this has resulted in nausea, vomiting, and CNS restlessness.

Dental Health: Vasoconstrictor/Local Anesthetic Precautions

No information available to require special precautions

Mental Health: Effects on Mental Status

May cause nervousness or restlessness
