title: Beta-endorphins as possible markers for therapeutic drug monitoring.
abstract: This study was performed in order to investigate possible role of brain beta-endorphins as markers of antidepressive drugs therapy monitoring. Experiment was done using amitriptyline and trazodone as antidepressants. For quantification of brain beta-endorphins we used RIA technique. Our results showed significant decrease of brain beta-endorphins concentration in drug-pretreated animals, vs. those in of control group treated with 0,95% NaCl. The lower values were obtained in trazodone pre-treated animals. This study shows that use of psychoactive drugs have influence on brain beta-endorphins concentration. beta-endorphins could be of great importance, used as markers for evaluation of patient treatment.
