[General principles of drug evaluation within the framework of drug policy]

This paper reviews the problems connected with drug evaluation in particular periods of its development. Requirements for drug registration, which represents the entrance of the drug on the market, are created by legislation. Drug application in the therapeutic process is determined by several factors and state regulations. The amount of evidence, reliability and validity of the facts should be the key factors of drug selection within the ambit of drug politics. Categorization of drugs means drug selection with regard to state reimbursement by means of health-insurance companies. Methods of drug categorization together with further regulations by means of positive letters, hospital blanks, should respect the criteria of professionality, transparency and sociopharmacology. Effective prognostication of drug use should ensure well-proportioned accessibility of effective safe drugs within the ambit of rational pharmacotherapy.
