Turner ES, Greenberger PA, Patterson R "Management of the pregnant asthmatic patient. If the serum sample is drawn more than two hours after the dose, the results must be interpreted with caution since the concentration may not be reflective of the peak concentration. In contrast, when signs or symptoms of theophylline toxicity are present, the serum sample should be obtained as soon as possible, analyzed immediately, and the result reported to the clinician without delay. Smokers Tobacco and marijuana smoking appears to increase the clearance of theophylline by induction of metabolic pathways. Theophylline clearance has been shown to increase by approximately 50% in young adult tobacco smokers and by approximately 80% in elderly tobacco smokers compared to non-smoking subjects. Passive smoke exposure has also been shown to increase theophylline clearance by up to 50%. Abstinence from tobacco smoking for one week causes a reduction of approximately 40% in theophylline clearance. Careful attention to dose reduction and frequent monitoring of serum theophylline concentrations are required in patients who stop smoking see . Use of nicotine gum has been shown to have no effect on theophylline clearance. What is theophylline Theo-24? Follow your doctor's instructions about whether to take your medication with food or on an empty stomach. Take the medication the same way every time.

Safety and efficacy have not been established in patients younger than 12 years. Consider prophylactic anticonvulsant therapy. 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. The pharmacokinetics of theophylline vary widely among similar patients and cannot be predicted by age, sex, body weight or other demographic characteristics. In addition, certain concurrent illnesses and alterations in normal physiology see and co-administration of other drugs see can significantly alter the pharmacokinetic characteristics of theophylline. Within-subject variability in metabolism has also been reported in some studies, especially in acutely ill patients. Schatz M, Zeiger RS, Harden K, Hoffman CC, Chilingar L, Petitti D "The safety of asthma and allergy medications during pregnancy. P-450 1A2 or a closely related cytochrome.

Smoking changes the way your body uses theophylline, and you may need to use a different dose. Prophylaxis and treatment study results for each surfactant are combined. Administer a single dose of oral activated charcoal. 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. Phenytoin increases theophylline clearance by increasing microsomal enzyme activity. Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional. Enhance clearance of theophylline. Acute Clinical Effects: As with other surfactants, marked improvements in oxygenation and lung compliance may occur shortly after the administration of Infasurf. All controlled clinical trials with Infasurf demonstrated significant improvements in fraction of inspired oxygen FiO2 and mean airway pressure MAP during the first 24 to 48 hours following initiation of Infasurf therapy. arcoxia

Careful monitoring of side effects and drug blood levels is recommended. LANTUS Motif de la demande de renouvellement de l'inscription sur la liste des médicaments remboursés par l'assurance nationale. 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. The increase in clearance associated with smoking is presumably due to stimulation of the hepatic metabolic pathway by components of cigarette smoke. The duration of this effect after cessation of smoking is unknown but may require 6 months to 2 years before the rate approaches that of a nonsmoker. FDA pregnancy category C.

Quibron is to be used only by the patient for whom it is prescribed. Do not share it with other people. Do not keep outdated medicine or medicine no longer needed. 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. Use and dose must be determined by your doctor. 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. 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. Co-administration of theophylline with food or antacids does not cause clinically significant changes in the absorption of theophylline from immediate-release dosage forms. Discard any unused portion of the medication, and oral solution vials containing discolored solution or visible particulate matter. Administer multiple dose oral activated charcoal and measures to control emesis.

In one health maintenance organization, the frequency of hospital admissions for chronic overdosage of theophylline was about 1 per 1000 person-years exposure. Fluid and electrolyte abnormalities should be promptly corrected. Fever Fever, regardless of its underlying cause, can decrease the clearance of theophylline. The magnitude and duration of the fever appear to be directly correlated to the degree of decrease of theophylline clearance. aripiprazole
For products containing theophylline salts, the appropriate dose of the theophylline salt should be substituted for the anhydrous theophylline dose. No withdrawal symptoms have been reported following caffeine citrate treatment of less than 3 weeks. Get medical help right away if your asthma symptoms worsen or if you are using your quick-relief inhaler more than usual or more often than prescribed. Similarly, a patient with decreased theophylline binding may have a sub-therapeutic total drug concentration while the pharmacologically active unbound concentration is in the therapeutic range. If only total serum theophylline concentration is measured, this may lead to an unnecessary and potentially dangerous dose increase. In patients with reduced protein binding, measurement of unbound serum theophylline concentration provides a more reliable means of dosage adjustment than measurement of total serum theophylline concentration.
