Serum Concentrations at Steady State After multiple doses of immediate-release theophylline, steady state is reached in 30-65 hours average 40 hours in adults. 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.

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. Store Quibron at room temperature, between 59 and 77 degrees F 15 and 25 degrees C in tightly closed container. Store away from heat, moisture, and light. Do not store in the bathroom.

For most patients, steady-state will be reached after 3 days of dosing when no doses have been missed, no extra doses have been added, and none of the doses have been taken at unequal intervals. Serum theophylline concentrations may continue to increase after presentation of the patient for medical care as a result of continued absorption of theophylline from the gastrointestinal tract. Serial monitoring of serum theophylline serum concentrations should be continued until it is clear that the concentration is no longer rising and has returned to non-toxic levels. These observations were not associated with increased mortality.

Serum theophylline and phenytoin concentrations decrease about 40%. Table IV. Manifestations of theophylline toxicity. To guide a dose increase, the blood sample should be obtained at the time of the expected peak serum theophylline concentration; 5-6 hours after a dose at steady-state, drawn more than 6 hours after the dose. For most patients, steady-state will be reached after 3 days of dosing when no doses have been missed, no extra doses have been added, and none of the doses have been taken at unequal intervals.

The peak milk concentration occurred between one and three hours after ingestion of the dose. Irritability was reported in one infant whose mother took aminophylline. Adverse effects were not reported in the infants of the other women participating in this study. Exposure to the infant can be minimized by administering nursing prior to administration of theophylline to avoid peak milk concentrations. The clinical importance of these changes should be weighed against the potential therapeutic benefit of theophylline in individual patients. Since the time required to reach steady-state is a function of theophylline half-life, up to 5 days may be required to achieve steady-state in a premature neonate while only 2-3 days may be required in a 6 month old infant without other risk factors for impaired clearance in the absence of a loading dose.

Theophylline is a relatively weak bronchodilator, is less effective than an inhaled beta-2 selective agonist and provides no added benefit in the treatment of acute bronchospasm. If an inhaled or parenteral beta agonist is not available, a loading dose of an oral immediate release theophylline can be used as a temporary measure. generic famvir online canada

Elderly patients are at significantly greater risk of experiencing serious toxicity from theophylline than younger patients due to pharmacokinetic and pharmacodynamic changes associated with aging. Theophylline clearance is reduced in patients greater than 60 years of age, resulting in increased serum theophylline concentrations in response to a given theophylline dose. Protein binding may be decreased in the elderly resulting in a larger proportion of the total serum theophylline concentration in the pharmacologically active unbound form.

General information about quibron

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. Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. If the serum sample is drawn more or less than twelve 12 hours after the dose, the results must be interpreted with caution since the concentration may not be reflective of the peak concentration. triamcinolone

Theophylline is structurally classified as a methylxanthine. Treatment of cardiac arrhythmias Sinus tachycardia and simple ventricular premature beats are not harbingers of life-threatening arrhythmias, they do not require treatment in the absence of hemodynamic compromise, and they resolve with declining serum theophylline concentrations. Other arrhythmias, especially those associated with hemodynamic compromise, should be treated with antiarrhythmic therapy appropriate for the type of arrhythmia. Decreases theophylline clearance by inhibiting hydroxylation and demethylation. costco pharmacy sucralfate cost
