Alprazolam
Also known as: ALPR
Use
The Alprazolam test is used to optimize the dosing and monitor patient adherence for those taking Alprazolam, commonly known as Xanax, Xanor, Alprax, or Niravam. It assists healthcare providers in therapeutic drug monitoring, allowing for adjustment of dosage to achieve desired therapeutic effects, while mitigating adverse effects such as somnolence, lightheadedness, and muscle tremors. This test measures the concentration of Alprazolam in the patient's serum or plasma to ensure it stays within the therapeutic range, which varies depending on the use case (e.g., anxiety or panic disorders) and dosage regimen.

Limitations
Interpretation of results should consider known variance in patient response to Alprazolam and possible interactions with other substances the patient might be taking. Furthermore, gel separator tubes and certain anticoagulants such as sodium citrate are unsuitable for this test, and improper handling leading to hemolysis might compromise the specimen. The stability of Alprazolam is time-sensitive, and repeated freeze/thaw cycles should be avoided to prevent degradation.
