introduction Bio ethics and preclinical and clinical trial by srota dawn

  1. 1. By SROTA DAWN M.PHARM (PHARMACOLOGY)
  2. 2. INTRODUCTION: The term bioethics formed by two different words Biology + Ethics Biology : The scientific study of life and of living organisms. Ethics : A set of principles of right conduct. Motivation based on ideas of right and wrong
  3. 3. Definition of Bioethics Bioethics is defined as the study of the ethical and moral implications of new biological discoveries and biomedical advances; mostly in the fields of genetic engineering and drug research. In medicine, it can be found in Hippocratic Oath which was first mentioned in ancient Greece Actual meaning of Bioethics [Greek ] bios ~ life; ethos~ behavior)
  4. 4. Why we need bioethics • deciding what we should do (what decisions are morally right or acceptable); • explaining why we should do it (how do we justify our decision in moral terms); and • describing how we should do it (the method or manner of our response when we act on our decision).
  5. 5. Ethics Bioethics Clinical Ethics Research ethics Resource Allocation ethics Public Health ethics Nursing ethics other Business ethics Environmental ethics Social ethics Organizational ethics IT ethics Other
  6. 6. Research ethics Preclinical study related ethics Clinical study related cthics
  7. 7. Preclinical research After synthesising/identifying a prospective compound(s), it is tested on animals to expose its whole pharmacological profile. It is an evaluation process where unfavourable compounds are get rejected in each step, so that only a few out of thousand compounds reach the stage when administration to man (clinical study) is considered.
  8. 8. Parameters to be checked in preclinical studies(GLP) • Screening tests • tests on isolated organs, bacterial cultures • test on animal models of human disease • general observational test • confirmatory tests • mechanism of action • systemic pharmacology • quantitative tests • pharmacokinetic studies • toxicity tests • acute • Sub acute • Chronic • special long term toxicity • reproductive toxicity and teratogenicity • mutagenicity • carcinogenicity
  9. 9. Laboratory animal Rodents Mouse Rat Guinea pig Hamster Rabbit Larger animal Cat Dog Human primates
  10. 10. Legal regulations for the use of animals in preclinical study ‘Russel and Burch’ In their book ‘ The Principles of humane experimental technique ’ (1959) Gave a concept of three ‘R’s Reduction  Refinement  Replacement
  11. 11. in INDIA PREVENTION OF CRUELTY TO ANIMALS ACT 1960 Is provided for animal safety during clinical studies CPCSEA was established under that provision CPCSEA is the COMMITTEE FOR THE PURPOSE OF CONTROL AND SUPERVISION OF EXPERIMENTS ON ANIMAL
  12. 12. UTILITY OF CPCSEA These guidelines provide a clear idea about the use of animals during experiments using animals. All labs doing animal work had to be registered with the CPCSEA and had to follow a set of rules. The main criteria of this committee is ‘TO PROMOTO HUMANE CARE OF ANIMALS USED FOR EXPERIMENTS’ It provides specifications that will enhance Animal well being
