Patients with more rapid metabolism, clinically identified by higher than average dose requirements, should receive a smaller dose more frequently to prevent breakthrough symptoms resulting from low trough concentrations before the next dose. A reliably absorbed slow-release formulation will decrease fluctuations and permit longer dosing intervals. If any of these effects last or get worse, tell your doctor or pharmacist promptly. Erythromycin metabolite decreases theophylline clearance by inhibiting cytochrome P450 3A3. The classifications below are a general guideline only.

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. Older adults may be more likely to have side effects from theophylline. buy now generic feldene canada
Treat overdose as indicated see recommendations for chronic overdosage. If theophylline is subsequently resumed, decrease dose by at least 50% and recheck serum concentration after 3 days to guide further dosage adjustment.

Increases in the dose of theophylline should not be made in response to an acute exacerbation of symptoms of chronic lung disease since theophylline provides little added benefit to inhaled beta2-selective agonists and systemically administered corticosteroids in this circumstance and increases the risk of adverse effects. A peak steady-state serum theophylline concentration should be measured before increasing the dose in response to persistent chronic symptoms to ascertain whether an increase in dose is safe. Irritability; mild, temporary caffeine-like effects eg, headache, nausea, diarrhea, trouble sleeping; mild, temporary changes in behavior; restlessness; temporary increased urination. 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 steadystate theophylline regimen.

However, the total dose is usually not more than 400 milligrams per day as a single dose, usually in the morning, or divided and given two times per day.
The clinical importance of these changes should be weighed against the potential therapeutic benefit of theophylline in individual patients. There are several readily identifiable causes of reduced theophylline clearance. Theophylline is used to treat such as and , . It must be used regularly to prevent and shortness of breath. This belongs to a class of drugs known as xanthines. It works in the airways by relaxing muscles, opening breathing passages, and decreasing the lungs' response to irritants.

Ventilation should be supported until clearance of the liquid is accomplished. This product has not been found by the US FDA to be safe and effective and the product labeling has not been approved. 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. iressa price kroger

Overview Theophylline is rapidly and completely absorbed after oral administration in solution or immediate-release solid oral dosage form. Theophylline does not undergo any appreciable pre-systemic elimination, distributes freely into fat-free tissues and is extensively metabolized in the liver. Safety and efficacy have not been established in patients younger than 18 years. The dose is drawn into a syringe from the single-use vial using a 20-gauge or larger needle with care taken to avoid excessive foaming. Administration is made by instillation of the Infasurf suspension into the endotracheal tube.

This material does not endorse drugs, diagnose patients, or recommend therapy. In patients with chronic asthma, including patients with severe asthma requiring inhaled corticosteroids or alternate-day oral corticosteroids, many clinical studies have shown that theophylline decreases the frequency and severity of symptoms, including nocturnal exacerbations, and decreases the “as needed” use of inhaled beta-2 agonists. Theophylline has also been shown to reduce the need for short courses of daily oral prednisone to relieve exacerbations of airway obstruction that are unresponsive to bronchodilators in asthmatics. Infasurf calfactant Intratracheal Suspension is supplied sterile in single-use, rubber-stoppered glass vials containing 3 mL NDC 61938-456-03 and 6 mL NDC 61938-456-06 off-white suspension.

Get medical help right away if you have any very serious side effects, including: seizures. Lab tests, including blood theophylline levels, may be performed while you use Quibron. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments. Severe toxicity from theophylline overdose is a relatively rare event. In one health maintenance organization, the frequency of hospital admissions for chronic overdosage of theophylline was about 1 per 1000 person-years exposure. Infasurf has been administered every 12 hours for a total of up to 3 doses. 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.
While the mechanisms of action of theophylline are not known with certainty, studies in animals suggest that bronchodilation is mediated by the inhibition of two isozymes of phosphodiesterase PDE III and, to a lesser extent, PDE IV while non-bronchodilator prophylactic actions are probably mediated through one or more different molecular mechanisms that do not involve inhibition of PDE III or antagonism of receptors. IV over 30 minutes one time. Quibron is a combination xanthine derivative and expectorant. The xanthine derivative works by relaxing the smooth muscle surrounding the bronchial tubes air passages of the lungs, allowing the tubes to widen, and making breathing easier. Quibron improves contraction of the diaphragm the major breathing muscle. The expectorant works by increasing respiratory secretions and loosening mucus in the airways. Theophylline may also be used for purposes not listed in this medication guide. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. dostinex

Intratracheal Suspension is a sterile, non-pyrogenic lung surfactant intended for intratracheal instillation only. It is an extract of natural surfactant from calf lungs which includes phospholipids, neutral lipids, and hydrophobic surfactant-associated proteins B and C SP-B and SP-C. It contains no preservatives. Extended-release capsules meet Drug Release Test 6 as published in the current USP monograph for Theophylline Extended-release Capsules. 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. allegra
Increases theophylline clearance by increasing cytochrome P450 1A2 and 3A3 activity. Quibron-T is to be used only by the patient for whom it is prescribed. Do not share it with other people. F for at least 24 hours is probably required to produce a clinically significant increase in serum theophylline concentrations. However, these observations have not been replicated in other adequate and well-controlled trials and their relevance to the intended population is unknown.
