Part Descriptions

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.

LP20176-1   trough
In medicine, a trough level is the lowest level that a medicine is present in the body. In a medicine that is administered periodically, the trough level should be measured just before the administration of the next dose in order to avoid overdosing. It should be contrasted with a "peak level", which is the highest level of the medicine in the body, and the "average level", which is the mean level over time. It helps in therapeutic drug monitoring. It is widely used in clinical trials for newer medicines for its therapeutic effectiveness and safety.
