Lanophyllin is a xanthine derivative that inhibits phosphodiesterase, leading to increased intracellular cyclic AMP levels. It also antagonizes adenosine receptors, resulting in bronchodilation, respiratory stimulation, and anti-inflammatory effects.
Selective beta2-adrenergic receptor agonist that relaxes bronchial smooth muscle by increasing cyclic AMP production via adenylate cyclase activation.
Treatment of bronchial asthma,Chronic obstructive pulmonary disease (COPD),Apnea of prematurity (off-label)
Treatment of bronchospasm in patients with COPD,Long-term maintenance treatment of asthma
5-6 mg/kg IV loading dose over 20-30 minutes, then 0.4-0.6 mg/kg/hour continuous IV infusion; maintenance oral dose 300-600 mg/day in divided doses every 8-12 hours.
AEROLONE is not a recognized drug; no standard dosing available.
Terminal elimination half-life is 7-9 hours in healthy adults; increases to 20-30 hours in congestive heart failure, cirrhosis, or severe COPD; decreases to 3-5 hours in smokers (tobacco or marijuana) due to enzyme induction.
Terminal elimination half-life is approximately 12-15 hours in adults; prolonged to 24-30 hours in severe renal impairment (Cr Cl <30 m L/min).
Primarily hepatic via CYP1A2, with minor contributions from CYP2E1 and CYP3A4. Metabolites include 3-methylxanthine, 1-methyluric acid, and 1,3-dimethyluric acid.
Primarily metabolized by CYP3A4 and to a lesser extent CYP2D6, with conjugation to inactive metabolites.
Renal excretion of unchanged drug accounts for approximately 10% of elimination; hepatic metabolism accounts for 90%, with metabolites excreted in urine. Biliary/fecal excretion is negligible (<2%).
Primarily renal excretion of unchanged drug (approximately 65%) and hepatic metabolism (35%), with metabolites excreted in urine and feces. Biliary/fecal elimination accounts for <10%.
Approximately 40% bound to albumin; binding is nonlinear and decreases at higher serum concentrations.
Approximately 88% bound, primarily to albumin and alpha-1-acid glycoprotein.
0.4-0.7 L/kg, approximating total body water (0.45 L/kg in adults). Vd is increased in neonates (0.6 L/kg) and decreased in obesity (0.3-0.4 L/kg) due to reduced lean body mass.
3.5-5.0 L/kg, indicating extensive extravascular distribution and tissue binding.
Oral immediate-release: 90-100%; Oral sustained-release: 80-100% relative to immediate-release; Rectal solution: 100%; Rectal suppository: 60-80% (erratic).
Oral: 35-50% (first-pass metabolism); Inhalation: 15-30% (dependent on device and technique); Intravenous: 100%.
For GFR <30 m L/min: reduce maintenance dose by 50%; consider monitoring serum concentrations.
No data; not applicable.
Child-Pugh Class A: reduce dose by 50%; Child-Pugh Class B: reduce dose by 75%; Child-Pugh Class C: avoid use or use with extreme caution with 80% dose reduction.
No data; not applicable.
IV loading dose: 5-7 mg/kg over 20-30 minutes; maintenance IV infusion: 0.5-1 mg/kg/hour for ages 1-9 years, 0.4-0.7 mg/kg/hour for ages 9-16 years; oral: 10-20 mg/kg/day in divided doses every 6-8 hours, maximum 600 mg/day.
No data; not applicable.
Elderly patients: reduce loading dose to 4-5 mg/kg; maintenance dose 0.2-0.3 mg/kg/hour IV or 200-400 mg/day oral; monitor serum theophylline levels closely due to decreased clearance.
No data; not applicable.
None explicitly required by FDA, but use with caution due to narrow therapeutic index and potential for severe toxicity.
None
Narrow therapeutic index; monitor serum concentrations regularly. Risk of arrhythmias, seizures, and gastrointestinal bleeding. Use lower doses in heart failure, liver disease, and elderly. Avoid abrupt discontinuation due to withdrawal symptoms.
Paradoxical bronchospasm,Cardiovascular effects (e.g., increased heart rate, QT prolongation),Hypokalemia,Hyperglycemia
Hypersensitivity to xanthines, active seizure disorders, severe arrhythmias, and uncontrolled hyperthyroidism.
Hypersensitivity to arformoterol or any component of the formulation
Avoid grapefruit and grapefruit juice due to CYP3A4 inhibition increasing theophylline levels. Limit caffeine intake (coffee, tea, cola) as it may add to theophylline's stimulant effects. High-fat meals may delay absorption; take consistently with or without food.
No significant food interactions. Avoid grapefruit juice as it may affect metabolism of the corticosteroid component.
Insufficient human data; animal studies show no evidence of teratogenicity at clinically relevant doses. First trimester: no known increase in major malformations. Second and third trimesters: no known adverse fetal effects. However, use only if clearly needed.
No evidence of teratogenicity in animal studies at doses up to 10 mg/kg/day (approximately 120 times the maximum recommended human daily inhaled dose). In humans, no controlled studies exist; however, data from postmarketing reports do not suggest an increased risk of structural anomalies. First trimester: limited data preclude definitive risk assessment, but no pattern of major birth defects has emerged. Second and third trimesters: no known fetal harm from inhaled doses; however, potential for fetal adrenal suppression with prolonged high-dose systemic exposure.
Excreted into breast milk; M/P ratio approximately 0.6-0.8. Relative infant dose is low (<10% of maternal weight-adjusted dose). No reports of adverse effects in breastfed infants. Caution advised in preterm or ill infants.
Unknown whether fluticasone propionate is excreted in human breast milk. Other corticosteroids are excreted in breast milk in low amounts, and inhaled doses result in negligible systemic levels, predicting unlikely significant infant exposure. M/P ratio not determined. Caution advised; weigh risk of maternal obstructive airway disease exacerbation against potential infant risks (adrenal suppression, growth retardation).
Pregnancy reduces theophylline clearance by 30-50%, especially in the third trimester. Dose may need reduction by up to 50% to maintain therapeutic levels. Monitor levels closely and adjust accordingly. Postpartum clearance rapidly returns to prepregnancy levels, requiring dose increase to avoid subtherapeutic levels.
No specific dose adjustment required based on pharmacokinetic changes; pregnancy may cause decreased airway reactivity but no significant changes in fluticasone clearance. Maintain lowest effective dose to control asthma. No dose increase recommended solely due to pregnancy. Monitor asthma control and adjust dose as per standard guidelines.
LANOPHYLLIN is a fixed-dose combination of lansoprazole, a proton pump inhibitor, and theophylline, a methylxanthine bronchodilator. Monitor serum theophylline levels due to lansoprazole's potential to inhibit CYP1A2, increasing theophylline toxicity risk. Avoid in patients with hepatic impairment or acute asthma exacerbation. Taper theophylline to prevent withdrawal seizures.
AEROLONE is a combination inhaler containing an inhaled corticosteroid (fluticasone propionate) and a long-acting beta2-agonist (salmeterol). Advise patients to rinse mouth with water after each use to reduce risk of oral candidiasis. Not for acute bronchospasm; use a rescue inhaler (short-acting beta agonist) as needed. Monitor for increased heart rate, palpitations, or tremor. Do not stop abruptly; taper dose under medical supervision if discontinuing.
Take this medication exactly as prescribed, usually once daily in the morning.,Swallow the capsule whole; do not crush or chew.,Avoid drinking alcohol or consuming grapefruit products while on this medication.,Report symptoms like nausea, vomiting, palpitations, or seizures immediately.,Do not stop abruptly; consult your doctor for gradual dose reduction.
Use AEROLONE exactly as prescribed; do not exceed recommended dose.,Rinse your mouth with water after each use (do not swallow) to prevent thrush.,This medication is not for sudden breathing problems; always keep your rescue inhaler (e.g., albuterol) with you.,Do not stop using this medicine without talking to your doctor, as stopping suddenly may worsen your breathing.,Seek immediate medical help if you experience worsening asthma, chest pain, or allergic reaction.
