A fluorometric method for determining bethanidine in blood plasma is described. The bethanidine is extracted into chloroform, a drug-dye complex with eosin Y is formed, and the fluorescence is measured (excitation, 535 nm; fluorescence, 560 nm). The assay detects 0.02 muM bethanidine (4 ng/ml) in plasma. The relative fluorescence of several body constituents and antihypertensive drugs is negligible. The plasma levels of bethanidine in four hypertensive patients receiving this drug were measured.
本文描述了一种测定血浆中苄乙胍的荧光法。苄乙胍被萃取到氯仿中,与曙红Y形成药物-染料复合物,然后测量荧光(激发波长535nm;发射波长560nm)。该检测方法可检测出血浆中0.02μM的苄乙胍(4ng/ml)。几种人体成分和抗高血压药物的相对荧光可忽略不计。测定了四名接受该药物治疗的高血压患者血浆中苄乙胍的水平。
