WHAT ARE THE SEVEN RULES OF TESTING DRUGS OF IBN SINA?
Prof. Dr. Kadircan Keskinbora, Ph.D. Ibn Sina did not write a book on pharmacology, but the second and fifth volumes o f his book, El Kanun fi’t-Tibb (Qanun) which consisted of 5 books are on pharmacology. In this study, seven rules put forward by Ibn Sina to try drugs are briefly discussed. Ibn Sina begins the second book (on simple medicines or materia medica, second volume) with a discussion of the nature and quality of medicines (each given a dual nature, cold or hot, dry or moist) and the way they are mixed. Their quality and the way drugs are mixed affect their effectiveness. Seven Rules of Testing Drugs of Ibn Sina are following: The drug must be free from any extraneous accidental quality It must be used on a simple, not a composite disease The drug must be tested with two contrary types of diseases, because sometimes a drug cures one disease by its essential qualities and another by its accidental ones 5 The quality of the drug must correspond to the strength o f the disease. For example, there are some drugs whose heat is less than the coldness o f certain diseases, so that they would have no effect on them The time of action must be observed, so that essence and accident are not confused The effect of the drug must be seen to occur constantly or in many cases, for if this did not happen, it was an accidental effect The experimentation must be done with the human body, for testing a drug on a lion or a horse might not prove anything about its effect on man. One of the few systematic comparisons o f drug studies in animals and humans, the inconsistency of the study’s authors due either to bias or the inability o f animal models to adequately mimic clinical disease is significant. In each of Ibn Sina’s seven rules, modern concepts of drug testing can be closely defined. His seventh rule in particular remains very relevant to today’s realities. Download 5.86 Mb.
