GENETIC VARIABILITY OF PHARMACOKINETICS AND PHARMACODYNAMICS OF ANALGESICS (LAYERED MEDICINE)

Pain therapy, the most widely spread disorder, tends more as other diseases, to administration of drug molecules targeted to the affected tissue at the right dose, or to the patient or patient groups (personalized medicine). A decisive determinant of this strategy is the genetic one, which is to some extent the basis of the variability of pharmacokinetic and pharmacodynamic response to analgesics in the patient population. The differences in action and response to analgesics are due in these cases to hyperfunctional or nonfunctional uni-nucleotide gene polymorphisms encoding enzyme-modified transport proteins or receptors involved in the biotransformation and dynamics of analgesics. Genomic testing increases therapeutic efficacy and avoids adverse effects especially in patients with long-term therapies.   &nbsp
