Discuss specific use of drug and side effects with patient as it relates to treatment. HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? How should I take theophylline? 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. Theophylline Tablets are not to be chewed or crushed because it may lead to a rapid release of Theophylline with the potential for toxicity. The scored tablet may be split. Patients receiving Theophylline tablets may pass an intact matrix tablet in the stool or via colostomy. These matrix tablets usually contain little or no residual Theophylline. Theophylline concentration when afebrile may be at greater risk of toxic effects from decreased clearance during sustained fever. Case reports of theophylline overdose in humans and animal studies suggest that phenytoin is ineffective in terminating theophylline-induced seizures. The doses of benzodiazepines and phenobarbital required to terminate theophylline-induced seizures are close to the doses that may cause severe respiratory depression or respiratory arrest; the clinician should therefore be prepared to provide assisted ventilation. Elderly patients and patients with COPD may be more susceptible to the respiratory depressant effects of anticonvulsants. Barbiturate-induced coma or administration of general anesthesia may be required to terminate repetitive seizures or status epilepticus. General anesthesia should be used with caution in patients with theophylline overdose because fluorinated volatile anesthetics may sensitize the myocardium to endogenous catecholamines released by theophylline. Enflurane appears less likely to be associated with this effect than halothane and may, therefore, be safer. Neuromuscular blocking agents alone should not be used to terminate seizures since they abolish the musculoskeletal manifestations without terminating seizure activity in the brain.

Taking Theophylline extended-release tablets immediately after a high-fat content meal may result in a somewhat higher C max and delayed T max and somewhat greater extent of absorption. The least amount of medicine that controls the asthma symptoms is used. Theophylline increases renal lithium clearance.
Each bead is an individual extended-release delivery system. After dissolution of the capsules these beads are released and distributed in the gastrointestinal tract, thus minimizing the probability of high local concentrations of theophylline at any particular site. CYP1A2 Inhibitors Moderate: May decrease the metabolism of CYP1A2 Substrates. Most of the side effects of aminophylline theophylline have been dependent on serum concentrations. BALF from asthmatic patients. ZYFLO. This includes all prescription and nonprescription medicines. Minton NA, Glucksman E, Henry JA. Prevention of drug absorption in simulated theophylline overdose.

Slow-release theophylline has an even greater risk for causing side effects than the short-acting medicine. Monitor the patient and obtain serial Theophylline concentrations every 2-4 hours to gauge the effectiveness of therapy and to guide further treatment decisions. The steady-state peak serum Theophylline concentration is a function of the dose, the dosing interval, and the rate of Theophylline absorption and clearance in the individual patient. buy cheapest plavix mastercard uk
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.

Several studies have described the clinical manifestations of theophylline overdose and attempted to determine the factors that predict life-threatening toxicity. Charcoal must be retained in, and pass through, the gastrointestinal tract to be effective; emesis should therefore be controlled by administration of appropriate antiemetics. Alternatively, the charcoal can be administered continuously through a nasogastric tube in conjunction with appropriate antiemetics. A single dose of sorbitol may be administered with the activated charcoal to promote stooling to facilitate clearance of the adsorbed theophylline from the gastrointestinal tract. Sorbitol alone does not enhance clearance of theophylline and should be dosed with caution to prevent excessive stooling which can result in severe fluid and electrolyte imbalances. Commercially available fixed combinations of liquid charcoal and sorbitol should be avoided in young children and after the first dose in adolescents and adults since they do not allow for individualization of charcoal and sorbitol dosing. gefitinib
