Pharmacogenetic analysis detects genetic changes that influence the efficacy of drugs. If genetic variants affect proteins responsible for the metabolization of substances, their tolerability and efficacy can be severely altered. These drugs include antidepressants, painkillers, neuroleptics, chemotherapeutics, AIDS drugs, thrombosis drugs, anesthetics, beta-blockers, or statins.
A specific enzyme’s reduced activity can lead to increased drug levels at the standard dosage, which is not infrequently accompanied by undesirable side effects. In the case of pharmaceuticals that are only activated by metabolization, the therapeutic effect may be absent altogether. Similarly, increased enzyme activity, due to the resulting increased drug degradation rate, leads to insufficient efficacy of the therapy.
The pharmacogenetics option analyzes known variants in 22 genes involved in drug metabolism. If certain gene variants are detected, the treating physician can adjust the therapy individually. With the help of pharmacogenetic analysis, serious side effects can be minimized, and treatment failure avoided.
