Term Description

Lithium is measured for compliance and toxicity. The standard draw time for lithium is at least 10 - 12 hours after the previous dose (i.e., in morning before subsequent dose) to allow for absorption and distribution to occur. This is called the trough.

Part Descriptions

LP16175-9   Lithium
Lithium, symbol Li and atomic number 3, is one of only four elements thought to have been created in the first few seconds following the "Big Bang" nucleosynthesis. It is in group 1 of the periodic table, among the alkali metals and is the lightest solid element. Lithium is a soft, silver white metal that does not exist on earth in its pure form. Lithium reacts with oxygen to form black lithium oxide (Li2 O). It therefore has to be stored under the cover of oil to stop its oxidation. Lithium metal is used primarily in heat-transfer applicationns such as batteries (mainly cell phone and camera batteries), household appliances (toasters and microwaves) and in high performance alloys (aircraft construction).

LP16175-9   Lithium
Lithium is useful in the treatment of bipolar disorder. Lithium salts may also be helpful for related diagnoses, such as schizoaffective disorder and cyclic major depression. The active part of these salts is the lithium ion Li+. They may increase the risk of developing Ebstein's cardiac anomaly in infants born to women who take lithium during the first trimester of pregnancy. Lithium has also been researched as a possible treatment for cluster headaches. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

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.
