Xenon
/api/v1/drug/xenonMechanism of action
Sourced from openFDAMechanism-of-action class: Unknown Cellular or Molecular Interaction.
Indications
Sourced from openFDA- Xenon Xe 133 Gas has been shown to be valuable for diagnostic inhalation studies for the evaluation of pulmonary function, for imaging the lungs and may also be applied to assessment of cerebral blood flow.
Contraindications
Sourced from openFDA- None known.contraindicated
Dosage & administration
Sourced from openFDAXenon Xe 133 Gas is administered by inhalation from a closed respirator system or spirometer. The final patient dose should be measured by a suitable radioactivity calibration system immediately prior to administration. The recommended activity range employed for inhalation by the average patient (70 kg) is: Pulmonary function including imaging: 74 to 1110 megabecquerels (2 to 30 millicuries) Cerebral blood flow: 370 to 1110 megabecquerels (10 to 30 millicuries) This may be administered as a bolus into the tubing near the patient's mouthpiece or mask after the completion of a tidal exhalation, or by rebreathing for a period of approximately 5 minutes of the Xenon Xe 133 gas in equilibrium with the air contained in the closed system at concentrations of the radionuclide that may vary from 37 to 222 megabecquerels (1.0 to 6.0 millicuries) per liter.
Warnings & precautions
Sourced from openFDAXenon Xe 133 Gas delivery systems, i.e., respirators or spirometers, and associated tubing assemblies must be leakproof to avoid loss of radioactivity into the laboratory environs not specifically protected by exhaust systems. Xenon Xe 133 Gas adheres to some plastics and rubber and should not be allowed to stand in tubing or respirator containers. Loss of radioactivity due to such adherence may render the study nondiagnostic.
Adverse reactions
Sourced from openFDAAdverse reactions specifically attributable to Xenon Xe 133 Gas have not been reported.
Use in specific populations
Sourced from openFDAPregnancy Animal reproduction studies have not been conducted with Xenon Xe 133 Gas. It is also not known whether Xenon Xe 133 Gas can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Xenon Xe 133 Gas should be given to a pregnant woman only if clearly needed. Ideally, all examinations that use radiopharmaceuticals, especially those elective in nature, of a woman of childbearing capability should be performed during the first few (approximately 10) days following the onset of menses.
