Part Description

LP14732-9   Phenytoin
An anticonvulsant that is used to treat a wide variety of seizure disorders. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its side effects and interactions with other drugs.

Change Reason
The Property has been changed from ACnc to reflect the new model for ordinal terms where results are based on a cut-off value.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
