Pharmacogenetics Ppt

What is Pharmacogenetics?- Every year in the USA alone 2 million

people experience adverse drug effects and more than a 100,000 die

from those reactions.

- Another horrible fact is that the drugs in today’s society are only effective

in 60 % of the population.

What can we do to stop these adverse drug effects? How can we develop

drugs that can be effective for everyone?

THE ANSWER IS PHARMACOGENETICS

Current Clinical Methods₋ Nico Test for personalised regimen to

quit smoking ₋ Amplichip for CYP 450₋ PCR based strategy for CYP 2D6

genotyping₋ Tratuzumab: first drug with clinical

application₋ Thiopurines: immunomodulating

drugs for leukemia and chronic inflammatory conditions

₋ Dosing considerations for other drugs such as Ironitecan, Warfarin, Tamoxifen, and Abacavir

₋ FDA has labelled 10% of its recently approved drugs with pharmacogenomic information

Ongoing Research on CYP₋ Cytochrome P450 superfamily of

enzymes

₋ Found all over the body but major enzymatic activity occurs in hepatic CYPs

₋ Bioactivation and metabolism of approximately 75% of drugs gives CYPs prominence in pharmacogenetics research

₋ Pharmacogenetic research is playing a major role in dosing of Warfarin (an anticoagulant)

Pharmacogenetics vs Bioethics

Main ethical concerns are combination of the following:

- Unequal distribution of

benefits/resources - Invasion of medical privacy - Discrimination due to the

involvementtof genetic tests - Research/business conflict-of-

interest

Major Drugs Ineffective For Many

…and harmful to some

Costs ImpactIncrease in costs - New Techniques need to be developed - Requires new training - Requires new facilities - Segmentation of market result in a reduction of revenue

generated - Post marketing surveillance cost Benefits - Shelved drugs coming back to life. - Fewer legal liabilities. - Saving lives.

Thank you for your attention
