An accurate, reliable procedure was developed for kinetic and therapeutic monitoring of paroxetine in human plasma. Steady-state plasma levels of paroxetine were measured for 18 geriatric patients (mean age 75) in a double-blinded study. Paroxetine doses ranged from 10 to 40 mg/day. The assay was suitable for patients on concurrent medications, and a small sample volume (1 ml) of patient plasma was used with sufficient sensitivity and specificity. After extraction and separation on a Beckman, Ultrasphere 5-microm C18 column (150x2 mm I.D.), the recovery (mean+/-S.D.) for paroxetine was determined to be 86.5+/-5.2%. The limit of quantitation for paroxetine in this assay was 5 ng/ml. Inter-assay reproducibility (C.V.) for the patient samples and quality controls ranged from 3.7 to 7.6%.

D015203 Reproducibility of Results The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
