Pharmacogenetic applications and in pharmacoeconomics in cancer patients

Drugs are assumed to make drug users better, but sometimes they can harm with their side effects. For the same drug, some patients show expected therapeutic effect while the others exhibit life-threatening drug side effects. In this inter individual variability, the etiology is multifactorial. Diet, environment, physiological influences, gender, age, and health status are possible factors. But variation in the genetic differences between individuals will have a major impact on drug activity. Variable drug response could be in part to genetically determined characteristics of target genes or drug metabolizing enzymes. Pharmacogenetics looks for these genetic factors which are linked to drug effects. With our increasing know ledges in the pharmacogenomic area we can say that ‘‘one size fits all’’ view is not correct. In cancer treatment, each individual’s unique genetic origin of cancers because of pharmacogenomics in predicting responses to treatment is used. Traditional cancer treatment has targeted dividing cells in the body. But cancer cells are not the only dividing cells in the body, for these reason cancer therapies are liable to have many side-effects. Especially for many cancer types, approved multiple drug strategies are used. The more drug response rate from using combination therapy means as the more expense and adverse reactions. Pharmacogenetic tests whose primer advantage for patients are approved and suggested to clinicians by significant organizations such as American Society of Clinical Oncology National Comprehensive Cancer Network and United States Food and Drug Administration. Health expenditures increased as a result of technological development in the field of health, as well as, increasingly constrained budgets allocated to health has started a period. Deciding the policies of this limited resource for public health managers to use evidence-based and public interest obligation arises. For the activity that led to the evaluation of new treatment options are the most important development in pharmacogenomics tests. These tests were done with the patient the appropriate medication and dosage to the patient profile, with no impact on the budget spent on drugs for the treatment of side effects will occur and the significant downsizing is provided in the budget spent. These developments are discussed within the scope of pharmacoeconomics.
