Abstract
A biologically active preparation for human or veterinary use for the selective blockade of opioid binding sites of the brain responsible for respiratory depression containing in a biologically active quantity the codeinone derivative of general formula (I) or its salt R.sup.1 means amino-, hydroxyl-, --NH-phenyl or --NH--CO--NH.sub.2 groups, R.sup.2 means a hydrogen atom or a hydroxyl group. The invention also covers a process for selective blocking the opioid binding sites of the brain responsible for respiratory depression by administering to a patient in need of an analgetic a preparation containing a codeinone derivative of general formula (I) or its salt preferably three times per day in doses of 2.5-5 mg. A preferred feature of the inventions is an analgetic composition containing a codeinone derivative of general formula (I) and in a mass ratio of 1:2-3 morphine of the formula (IV) or an other, biologically equipotent agonist type opiate or opioid compound and optionally inert, pharmaceutically acceptable accompanying materials.
