pharmacogenomics

Pharmacogenomics

1.Pharmacogenomics is the study of the role of the genome in drug response. Its name reflects its combining of pharmacology and genomics. Pharmacogenomics analyzes how the genetic makeup of an individual affects his/her response to drugs. 

2.pros
  • Improve drug safety, and reduce ADRs;
  • Tailor treatments to meet patients' unique genetic pre-disposition, identifying optimal dosing;
  • Improve drug discovery targeted to human disease; and
  • Improve proof of principle for efficacy trials
3.genome-wide technology on pharmacogenomics of mental illnesses including schizophrenia (SCZ), autism spectrum disorders (ASD), attention deficit hyperactivity disorder (ADHD), and obsessive compulsive disorder (OCD).

4.The effectiveness and toxicities of medications used in secondary stroke prophylaxis, dementia, seizure disorders, multiple sclerosis (MS), and Parkinson disease (PD) are all influenced by genetic polymorphisms.

review lithium as mood stabilizer

1.Lithium as a mood stabilizer has been used as the standard pharmacological treatment for Bipolar Disorder (BD)   2.Recent studies have also shown that it has the potential for the treatment of many other neurodegenerative disorders, including Alzheimer’s, Parkinson’s and Huntington’s disease, through its neurotrophic, neuroprotective, antioxidant and anti-inflammatory actions. -- Therefore, exploring its pharmacokinetic features and designing better lithium preparations are becoming important research topics.  ---Lithium is rapidly and completely absorbed from the gastrointestinal tract after oral administration. Its level is initially highest in serum and then is evidently redistributed to various tissue compartments. It is not metabolized and over 95% of lithium is excreted unchanged through the kidney, but different lithium preparations may have different pharmacokinetic features. Lithium has a narrow therapeutic window limited by various adverse effects, but some no...

Brain connectivity improves human aesthetic responses to music

Brain connectivity improves human aesthetic responses to music Abstract: 1. white matter connectivity between sensory processing areas in the superior temporal gyrus and emotional and social processing areas in the insula and medial prefrontal cortex explains individual differences in reward sensitivity to music. 2.  findings provide the first evidence for a neural basis of individual differences in sensory access to the reward system, and suggest that social–emotional communication through the auditory channel may offer an evolutionary basis for music making as an aesthetically rewarding function in humans. 3.carried out by -- Using a combination of survey data, behavioral and psychophysiological measures and diffusion tensor imaging, Conclusion: Results from diffusion tensor imaging show that white matter connectivity between auditory perceptual regions (pSTG) and regions of the brain important for emo- tional and social processing (aIns, mPFC) reflect individual diffe...

Drug toxicity of psychotropic drugs

Drug toxicity of psychotropic drugs. Drug toxicity is the development of severe, drug-related complications, which may require premature drug withdrawal or dose reduction. 1. acute toxicity is  highest in.                  antidepressants  lower in neuroleptics   very low in anxiolytics. 2. major problems stem  Anxiolytic ---misuse and overuse. neuroleptics --- tardive dyskinesia is a serious threat to longterm therapy.   antidepressants ---low therapeutic index and a resulting high incidence of severe and fatal poisoning cases, both intentional and accidental. 3.Poisoning death rates per million prescriptions were about 10 times higher for tricyclic antidepressants (TCAs) than for selective serotonin reuptake inhibitors (SSRIs), England and Wales, 1993-2004 4 .Psychotropic drugs with hepatotoxic potential can be classified based on their intended use:  1) antipsychoticsneuroleptics including phenothiazine...
