A high performance liquid chromatography method for the determination of mianserin in human serum was developed and validated. Doxepin was used as an internal standard. Mianserin was extracted from human serum using a liquid-liquid extraction with hexane:isoamyl alcohol (99:1, v/v). The sample was then dissolved in 0.05 M phosphoric acid (pH=3.0), and after separation on a Hichrom RPB (250 x 4.6 mm, 5 mm) column, the analytes were measured by ultraviolet detection at 214 nm. The recovery ranged from 86.1 to 94.5% for mianserin. The method was specific and linear over the concentration range of 2.0-128.0 ng/mL. The limit of quantification (LOQ) was established at 2.0 ng/mL (CV=13.8%). The accuracy range was from 92.5 to 107.5%. The method was used to measure mianserin in human serum samples obtained from healthy volunteers who had received a single oral dose of 30 mg mianserin. Pharmacokinetic parameters obtained for the mianserin were in agreement with the existing data.
