With dyphylline, as with theophylline, the less severe signs or symptoms of toxicity may not always precede the more serious ones such as sinus tachycardia, ventricular arrhythmias, or seizures the following side/adverse effects have been selected on the basis of their potential clinical significance (possible signs and symptoms in parentheses.

Whenever a patient receiving theophylline develops nausea or vomiting, particularly repetitive vomiting, or other signs or symptoms consistent with theophylline toxicity (even if another cause may be suspected), additional doses of theophylline should be withheld and a serum theophylline concentration measured immediately. Monitoring of serum theophylline concentrations by a fully mechanized enzyme immunoassay (emit) oellerich, m sybrecht, g w haeckel, r 1979-01-01 00:00:00 introduction there is an increasing demand for rapid and reliable assays for the determination of serum levels of drugs, which have a narrow therapeutic range, and/or dangerous side.

Concurrent administration of other drugs and xanthine containing beverages can affect some assay these substances do not interfere with results when measured by high-pressure liquid chromatography or emit indications: the symptomatic treatment of reversible bronchoconstriction associated with chronic theophylline toxicity is frequently.

Because of its wide use and toxicity at high concentrations, phenytoin is often the subject of overdose thin-layer chromatography or spectrophotometry is used for screening quantification usually requires gas- or high-performance liquid chromatography or immunoassay (eg emit, fpia.

Therapeutic drug monitoring (tdm) is the measurement of the serum level of a drug to ensure its concentration is within the therapeutic range a drug's serum therapeutic range or index is the concentration range in which the drug is known to be effective while causing little or no toxic effects to the patient.

The emit® 2000 theophylline assay is a homogeneous enzyme immunoassay intended for use in the quantitative analysis of theophylline in human serum or plasma these reagents are. Therapeutic drug monitoring the basic assumptions underlying therapeutic drug monitoring are that drug metabolism varies from patient to patient and that the plasma level of a drug is more closely related to the drug's therapeutic effect or toxicity than is the dosage.

Syva emit assays can provide accurate, efficient analysis of anticonvulsants, antiarrhythmics, aminoglycoside antibiotics and antiasthmatics drug overdose medical emergencies expanded tdm menu offering phenobarbital phenytoin quinidine salicylic acid theophylline. Theophylline toxicity is most likely to occur when serum concentrations exceed 20 micrograms/ml and becomes progressively more severe at higher serum concentrations over 3 g could be serious in an adult (40 mg/kg in a child.
