Pregabalin (Lyrica) is an anticonvulsant drug used to treat partial seizures. Pregabalin is also commonly prescribed to treat neuropathic pain and fibromyalgia. Measurement of the concentration of Pregabalin in serum is helpful in assessing compliance and monitoring patients with renal failure who generally require lower dosages.
Therapeutic concentration is 2 to 5 ug/mL when measured by liquid chromatography plus mass spectrometry. Toxicity may occur at serum concentrations greater than 10 ug/mL. Specimen requirement is a red top tube of blood.
