Metabolism Following oral dosing, theophylline does not undergo any measurable first-pass elimination. In adults and children beyond one year of age, approximately 90% of the dose is metabolized in the liver. Use: Short-term treatment of apnea of prematurity in infants. Theophylline has been studied in Ames salmonella, in vivo and in vitro cytogenetics, micronucleus and Chinese hamster ovary test systems and has not been shown to be genotoxic.
This drug passes into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breast-feeding. Skip next dose and decrease subsequent doses at least 25% even if no adverse effects are present. Recheck serum concentration after 3 days to guide further dosage adjustment. If symptomatic, consider whether overdose treatment is indicated see recommendations for chronic overdosage. SR is not intended for use in patients experiencing an acute episode of bronchospasm, patients who require rapid relief of such symptoms, or in patients with status asthmaticus. Status asthmaticus should be considered a medical emergency and is defined as that degree of bronchospasm which is not rapidly responsive to the usual doses of conventional bronchodilators. Optimal therapy for such patients often requires additional medication which may require parenteral administration close monitoring, and should preferably be conducted in an intensive-care setting.
Other medications can affect the removal of theophylline from your body, which may affect how theophylline works. Examples include cimetidine, disulfiram, fluvoxamine, interferon, mexiletine, propranolol, rifampin, drugs used to treat seizures such as carbamazepine, phenytoin St. John's wort, ticlopidine, among others.

Children may be more likely to experience mild, temporary behavior changes. Mild and temporary changes in behavior; temporary increased urination. 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. Parce que endossements obstinés de la drogue par les endocrinologues ont fusionné les mots hypothyroïdie et Synthroid comme le nez qui coule et inséparablement comme Kleenex. Pourquoi endocrinologues cautionne-Synthroid endocrinologues dicter d'autres spéTadalistates médicaux traditionnels croyances sur l'hypothyroïdie et son traitement. Une telle croyance est que le but de la thérapie appropriée de l'hormone thyroïdienne est d'amener la thyréostimuline niveau TSH dans le sang des patients dans la plage de référence anciennement appelé. Pour endocrinologues, lorsqu'un niveau des patients de la TSH est dans cet intervalle, le patient est dit être bien, même s'il ou elle reste handicapée par des symptômes d'hypothyroïdie. Traiter les patients hypothyroïdie selon ce critère a laissé des millions d'entre eux souffrant de maladies chroniques, les personnes handicapées, et mort prématurément. La raison est claire. Au cours de l'hypothyroïdie primaire, la glande pituitaire augmente sa libération de la TSH, l'élévation du niveau de sang au-dessus de la plage de référence. L'hypophyse est très sensible à T4, et de petites doses de T4 diminue la libération hypophysaire de TSH, descente dans la plage de référence. Des tissus autres que la glande pituitaire sont relativement insensible à de faibles doses de T4. des doses beaucoup plus élevées sont nécessaires pour normaliser le métabolisme de ces autres tissus. Cependant, T4 ne pas augmenter le métabolisme de nombreux tissus de patients, peu importe à quelle hauteur la dose. Seule une préparation d'hormone de la thyroïde qui contient T3 va accélérer ces patients, le métabolisme. Par conséquent, lorsque la thérapie T4 TSH normalise les niveaux de nombreux patients de sang, il laisse leur métabolisme subnormale. Ces patients restent symptomatiques malgré leurs taux de TSH normales. Cette constatation a conduit les chercheurs à exhorter les médecins à des patients thyroïde posologies d'hormones ne base par des taux de TSH. Compte tenu de cela, pourquoi ne endocrinologues approuvent résolument Synthroid comme la seule marque de l'hormone thyroïdienne tout patient hypothyroïdie jamais besoin d'utiliser La cause est une interaction complexe de facteurs. Parmi les plus marquantes sont des incitations financières à la spécialité d'endocrinologie du marketing d'entreprise de Synthroid. Les sociétés ont richement financé la spécialité. Celui qui paie les violons, bien sûr, donne le ton. Cette réalité rend la proposition plausible que le financement somptueux par ces sociétés a façonné endocrinologues croyances sur l'hypothyroïdie - croyances qui sont favorables, quid pro quo. aux intérêts financiers des sociétés, encore montré faux par des preuves scientifiques substantielles. De nombreuses preuves soutient la croyance que endocrinologues endossement de Synthroid a été fortement influencée par les incitations financières des sociétés. Un exemple est un don d'un million de dollars par Knoll à l'American Thyroid Society ATS pour financer la recherche de la thyroïde. Les études ATS fonds avec cet argent seront ceux dont les résultats sont de nature à favoriser les intérêts financiers de la société. Les études qui militeraient contre les sociétés d'intérêts financiers ne sont pas susceptibles d'être financés. Ce type de soutien mutuel assure une relation financière continue entre les organismes de recherche et les sociétés de financement. Réputé avocat thyroïdienne patient Mary Shomon a récemment noté que l'Association américaine des endocrinologues cliniques AACE La page web AACEs énumérant ses sponsors vérifie que Synthroid subventionne l'organisation. Knoll financé AACEs travaillent à élaborer des directives pratiques pour le diagnostic et le traitement de l'hypothyroïdie. Il est pas surprenant que les lignes directrices ne mentionnent aucun traitement pour l'hypothyroïdie autre que T4. Cette approbation de T4 concorde avec les endocrinologues souvent répétées appui public de Synthroid. Dr. Rhoda Cobin, président de AACE, a écrit récemment dans le Wall Street Journal que l'organisation ne cautionne pas des produits spécifiques. Pourtant, dans la même lettre, elle - haut fonctionnaire AACEs - approuvé Synthroid: Mary Shomon a souligné que la page d'accueil du site Synthroid affiche en évidence un AACE communiqué de presse en faveur de Synthroid. FDA action contre Synthroid En dépit de ces assurances par les endocrinologues, et en dépit de sociétés ayant commerTadalistaé Synthroid depuis 30 ans, la FDA n'a pas approuvé le produit pour le traitement de l'hypothyroïdie. Knoll a récemment demandé que la FDA renonce à des exigences de la FDA a refusé et exigé Knoll à appliquer pour une demande de drogue nouvelle suivant les tests appropriés pour la sécurité et l'efficacité. Les raisons de la FDA a donné pour sa décision au sujet de Synthroid contredisent les assurances de endocrinologues. La FDA a également écrit de Synthroid: L'agence a cité une longue histoire de problèmes de fabrication, subpotency, la stabilité et les problèmes de fiabilité. La raison du rappel était faible puissance au cours des études de stabilité. En 1991, Knoll a rappelé 26 lots subpotent de Synthroid en Février et les autres lots en Juin. Inspections d'une usine de fabrication Synthroid conduit à des citations pour les écarts de bonnes pratiques de fabrication: deux en Avril 1991, et neuf en Décembre 1992. Knoll distribué subpotent Synthroid en 1990, 1991 et 1992. La FDA a résumé: Le 1er Août, 2001 Abbott Labs, après l'acquisition de Knoll, soumis à la FDA une demande de drogue nouvelle pour Synthroid. Les personnes concernées par le problème Synthroid peut rester au courant des actions de la FDA contre son fabricant par bulletin Mary Shomons, Tirer Nos Cous. En résumé, les données indiquent que les incitations financières des commerçants de Synthroid ont influencé endocrinologues d'approuver le produit. Synthroid a une histoire de la fabrication, de la stabilité, et les problèmes de virilité, et il n'a pas répondu aux critères de la FDA pour l'efficacité et la sécurité. Ces problèmes avec la qualité des produits ont conduit à l'action de la FDA contre Synthroid. De nombreux médecins médicaux alternatifs indiquent que les résultats du traitement avec Synthroïde sont inférieurs à ceux des produits contenant à la fois T4 et T3 ou T3 seul. Références Lowe JC. Lettre au General Medical Council. Londres, Royaume-Uni, le 17 Avril 2001. Discontinuation of a concomitant drug that increases theophylline clearance will result in accumulation of theophylline to potentially toxic levels, unless the theophylline dose is appropriately reduced. Discontinuation of a concomitant drug that inhibits theophylline clearance will result in decreased serum theophylline concentrations, unless the theophylline dose is appropriately increased. Carcinogenesis studies and animal reproduction studies have not been performed with Infasurf. A single mutagenicity study Ames assay was negative. Transient caffeine-like adverse effects and excessive serum concentrations in slow metabolizers can be avoided in most patients by starting with a sufficiently low dose and slowly increasing the dose, if judged to be clinically indicated, in small increments See . Dose increases should only be made if the previous dosage is well tolerated and at intervals of no less than 3 days to allow serum theophylline concentrations to reach the new steady state.
About FAERS: The FDA Adverse Event Reporting System FAERS is used by FDA for activities such as looking for new safety concerns that might be related to a marketed product, evaluating a manufacturer's compliance to reporting regulations and responding to outside requests for information. Reporting of adverse events is a voluntary process, and not every report is sent to FDA and entered into FAERS. 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. Cord serum concentrations and infant serum concentrations have been reported to approximate the mother's serum concentrations immediately following birth. Infasurf was administered through a 5 French feeding catheter inserted into the endotracheal tube. 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. You may take theophylline with or without food, but take it the same way every time. The dose must be determined by your doctor. However, the total dose is usually not more than 400 milligrams per day, divided and given every 6 to 8 hours. General Monitoring Procedures Electrocardiographic monitoring should be initiated on presentation and continued until the serum theophylline level has returned to a nontoxic 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. Consult a healthcare provider if your baby continues to have apnea events; do not increase the dose of caffeine citrate without medical consultation. uroxatral

Tirer Nos Necks Out: La maladie de la thyroïde Nouvelles Rapport. The pharmacokinetics of theophylline have been studied in women during pregnancy. Studies throughout pregnancy have noted a significant decrease in the clearance of theophylline during the third trimester. The clearance was only slightly decreased during the first and second trimester. The plasma protein binding of theophylline also has been shown to decrease in the later stages of pregnancy. It is important to closely monitor the theophylline serum concentration and the patient for signs of toxicity during pregnancy. Fever, regardless of its underlying cause, can decrease the clearance of theophylline. Use Quibron-T with caution in the ELDERLY; they may be more sensitive to its effects.

The use of theophyllines is associated with an increase in heart rate which may progress to supraventricular tachycardia or ventricular arrhythmia at high serum drug concentrations. Appearance of cardiac adverse effects is generally an indication of theophylline toxicity, although patients with a history of tachyarrhythmias may be more susceptible to the chronotropic effect of these drugs. Therapy with theophyllines should be administered cautiously in such patients. Caution is also advised in patients with hypertension, hyperthyroidism, angina pectoris, or recent myocardial infarction, since high dosages of the drugs are associated with positive inotropic as well as chronotropic effects. Clinical monitoring of serum drug concentrations is recommended to prevent toxicity. Increased risk of ventricular arrhythmias. Once theophylline enters the systemic circulation, about 40% is bound to plasma protein, primarily albumin. Unbound theophylline distributes throughout body water, but distributes poorly into body fat. If any of these effects last or get worse, tell your doctor or promptly. If the serum sample is drawn more than two hours after the dose, the results must be interpretedwith caution since the concentration may not be reflective of the peak concentration.

Ventilation should be supported until clearance of the liquid is accomplished.
Caffeine Citrate: Use with caution in infants with impaired renal function; monitor serum drug concentrations and adjust dose accordingly to avoid toxicity. Theophylline is very similar to aminophylline and oxtriphylline. Do not take medications containing aminophylline or oxtriphylline while using theophylline. Treat overdose as indicated see recommendations for . If theophylline is subsequently resumed, decrease dose by at least 50% and recheck serum concentration after 3 days to guide further dosage adjustment. Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.
