The authors used high sensitive micellar enhanced fluorimetric method to monitor amiodarone blood-medical concentration. SLS severed as micellar reagent. Under experimental condition,we used 930 fluorophotommeter which made in China as the main analytic instrument,and obtained a series pharmacokinetic parameter ,eg. t_(1/2) (?) was 1.18 h, t_(1/2)(?)was 40.75 h, K_(21) was 0.278 l/h,K_(10) was 0.036 l/h,K_(12) was 0.291 l/h. The linear range of this method was 2 ? 10_(-9)～8 ? 10_(-6) mol/L,determined limit was 1.3 ? 10~(-9)mol/L, average recovery was 99.93%.
