ABSTRACT

Digoxin plays a part in healing of congestive heart failure in clinic. Its therapeutic dose is very approximate to toxic dose and even they overlap each other sometimes. There are many influencing factors on blood drug level of digoxin. Pharmacodynamics and pharmacokinetics varies with different individuality. It is indispensable to detecting blood drug level in order to treat disease and prevent intoxication. Integrating with the detecting-methods of blood drug level of digoxin home and broad, characteristic of many methods are summarized from sensitivity, linearity range, cross-reaction and precision. These methods include radio immunoassay, enzyme immunoassay, chemiluminescence immunoassay, fluorescence immunoassay and HPLC-MS-MS. These methods are popular for their specialized ascendancy. The cost of radio immunoassay is low. Enzyme immunoassay has good specificity. Sensitivity and stability of chemiluminescence immunoassay is very excellent. Fluorescence polarization immunoassay is sensitive and convenient. HPLC-MS-MS has high resolution and good specificity. One of the development tendencies is to combine two or more methods in detecting the blood drug level of digoxin which contribute to these methods integrated use.
