[Drug repositioning - antibiotics as cytostatics].

Antibiotics are considered to be one of the most important discoveries of medicine, which has significantly affected the mortality due to infectious diseases. Given their increasing use, certain problems arise over time, resulting from non-indicated and inadequate - administration of antibiotics. This results in increasing antibiotic resistance as well as a higher risk of side/adverse effects. Recently, these side effects of drugs have been used for indications other than those originally intended and approved. Such a process is called drug repositioning. Due to the recent increase in the cost of developing novel drugs and the high risk of failure in clinical trials, the pharmaceutical industry is trying to find new indications for existing drugs.
