Pharmacogenetics Ppt

  1. 1. What is Pharmacogenetics? <ul><li>- Every year in the USA alone 2 million people experience adverse drug effects and more than a 100,000 die from those reactions. </li></ul><ul><li>- Another horrible fact is that the drugs in today’s society are only effective in 60 % of the population. </li></ul><ul><li>What can we do to stop these adverse drug effects? How can we develop drugs that can be effective for everyone? </li></ul><ul><li>THE ANSWER IS PHARMACOGENETICS </li></ul>
  2. 2. Current Clinical Methods <ul><li>Nico Test for personalised regimen to quit smoking  </li></ul><ul><li>Amplichip for CYP 450 </li></ul><ul><li>PCR based strategy for CYP 2D6 genotyping </li></ul><ul><li>Tratuzumab : first drug with clinical application </li></ul><ul><li>Thiopurines : immunomodulating drugs for leukemia and chronic inflammatory conditions </li></ul><ul><li>Dosing considerations for other drugs such as Ironitecan , Warfarin , Tamoxifen , and Abacavir </li></ul><ul><li>FDA has labelled 10% of its recently approved drugs with pharmacogenomic information </li></ul>
  3. 3. Ongoing Research on CYP <ul><li>Cytochrome P450 superfamily of enzymes </li></ul><ul><li>Found all over the body but major enzymatic activity occurs in hepatic CYPs </li></ul><ul><li>Bioactivation and metabolism of approximately 75% of drugs gives CYPs prominence in pharmacogenetics research </li></ul><ul><li>Pharmacogenetic research is playing a major role in dosing of Warfarin (an anticoagulant) </li></ul>
  4. 4. Pharmacogenetics vs Bioethics <ul><li>Main ethical concerns are combination of the following:  </li></ul><ul><li>  </li></ul><ul><li>- Unequal distribution of benefits/resources </li></ul><ul><li>  </li></ul><ul><li>- Invasion of medical privacy </li></ul><ul><li>  </li></ul><ul><li>- Discrimination due to the involvementtof genetic tests </li></ul><ul><li>  </li></ul><ul><li>- Research/business conflict-of-interest </li></ul>
  5. 5. Major Drugs Ineffective For Many … and harmful to some
  6. 6. Costs Impact <ul><li>Increase in costs </li></ul><ul><li>     - New Techniques need to be developed </li></ul><ul><li>     - Requires new training </li></ul><ul><li>     - Requires new facilities </li></ul><ul><li>     - Segmentation of market result in a reduction of revenue generated </li></ul><ul><li>     - Post marketing surveillance cost </li></ul><ul><li>  </li></ul><ul><li>Benefits </li></ul><ul><li>     - Shelved drugs coming back to life. </li></ul><ul><li>      - Fewer legal liabilities. </li></ul><ul><li>     - Saving lives.  </li></ul>
