The listing of drugs in Tables II and III are current as of January 2, 1996. New interactions are continuously being reported for theophylline, especially with new chemical entities.
Other factors associated with decreased theophylline clearance include the third trimester of pregnancy, sepsis with multiple organ failure, and hypothyroidism. Careful attention to dose reduction and frequent monitoring of serum theophylline concentrations are required in patients with any of these conditions see . Other factors associated with increased theophylline clearance include hyperthyroidism and cystic fibrosis. There are several readily identifiable causes of reduced theophylline clearance. The drugs listed in Table II have the potential to produce clinically significant pharmacodynamic or pharmacokinetic interactions with theophylline. The information in the “Effect ” column of Table II assumes that the interacting drug is being added to a steady-state theophylline regimen.
Miscellaneous Other factors associated with decreased theophylline clearance include the third trimester of pregnancy, sepsis with multiple organ failure, and hypothyroidism.

Gender Gender differences in theophylline clearance are relatively small and unlikely to be of clinical significance. Significant reduction in theophylline clearance, however, has been reported in women on the 20th day of the menstrual cycle and during the third trimester of pregnancy. Severe cases, sometimes without previous warning, have led to cardiac arrhythmias, intractable seizures, and death. Endogenous lung surfactant is essential for effective ventilation because it modifies alveolar surface tension thereby stabilizing the alveoli. Lung surfactant deficiency is the cause of Respiratory Distress Syndrome RDS in premature infants. Infasurf restores surface activity to the lungs of these infants. Table V contains theophylline dosing titration schema recommended for patients in various age groups and clinical circumstances. Table VI contains recommendations for theophylline dosage adjustment based upon serum theophylline concentrations. Application of these general dosing recommendations to individual patients must take into account the unique clinical characteristics of each patient.

Your doctor may need to adjust your dose. Each of the aliquots was administered with the patient in one of four different positions prone, supine, right, and left lateral to facilitate even distribution of the surfactant. Repeat doses were administered as early as 6 hours after the previous dose for a total of up to 4 doses if the infant was still intubated and required at least 30% inspired oxygen to maintain a PaO2 less than or equal to 80 torr. These observations were not associated with increased mortality. SR Tablets should not be chewed or crushed. General Monitoring Procedures Electrocardiographic monitoring should be initiated on presentation and continued until the serum theophylline level has returned to a non-toxic level. Serum electrolytes and glucose should be measured on presentation and at appropriate intervals indicated by clinical circumstances. Fluid and electrolyte abnormalities should be promptly corrected.

Rx only Manufactured by: ONY, Inc. Amherst, NY 14228 Rev. Several studies have described the clinical manifestations of theophylline overdose and attempted to determine the factors that predict life-threatening toxicity. Whenever a patient receiving theophylline develops nausea or vomiting, particularly repetitive vomiting, or other signs or symptoms consistent with theophylline toxicity even if another cause may be suspected additional doses of theophylline should be withheld and a serum theophylline concentration measured immediately. In contrast, approximately 50% of the administered theophylline dose is excreted unchanged in the urine in neonates. Tablets are contraindicated in patients with a history of hypersensitivity to theophylline or other components in the product. Prophylaxis therapy at birth with Infasurf is indicated for premature infants less than 29 weeks of gestational age at significant risk for RDS.

Increasing the rate of theophylline clearance by extracorporeal methods may rapidly decrease serum concentrations, but the risks of the procedure must be weighed against the potential benefit. Do not administer this drug by intramuscular, subcutaneous, intrathecal, or intraperitoneal injection. BPD is bronchopulmonary dysplasia, diagnosed by positive X-ray and oxygen dependence at 28 days. Theophylline passes freely across the placenta, into breast milk and into the cerebrospinal fluid CSF. Saliva theophylline concentrations approximate unbound serum concentrations, but are not reliable for routine or therapeutic monitoring unless special techniques are used. An increase in the volume of distribution of theophylline, primarily due to reduction in plasma protein binding, occurs in premature neonates, patients with hepatic cirrhosis, uncorrected acidemia, the elderly and in women during the third trimester of pregnancy.

For a given population there is no single theophylline dose that will provide both safe and effective serum concentrations for all patients. Administration of the median theophylline dose required to achieve a therapeutic serum theophylline concentration in a given population may result in either sub-therapeutic or potentially toxic serum theophylline concentrations in individual patients. Infasurf is indicated for the prevention of Respiratory Distress Syndrome RDS in premature infants at high risk for RDS and for the treatment “rescue” of premature infants who develop RDS. Infasurf decreases the incidence of RDS, mortality due to RDS, and air leaks associated with RDS. At steady state, on a dosage regimen with 6-hour intervals, the expected mean trough concentration is approximately 60% of the mean peak concentration, assuming a mean theophylline half-life of 8 hours. The difference between peak and trough concentrations is larger in patients with more rapid theophylline clearance. In patients with high theophylline clearance and half-lives of about 4-5 hours, such as children age 1 to 9 years, the trough serum theophylline concentration may be only 30% of peak with a 6-hour dosing interval.
