PERSONALIZED MEDICINE: A MODERN MEDICAL APPROACH

Аннотация

Personalized medicine is a field of healthcare that aims to develop diagnostic, treatment, and preventive strategies based on the genetic characteristics, physiological condition, and lifestyle of each individual. This article discusses the concept of personalized medicine, its main directions, advantages, and applications in practice. Areas such as pharmacogenetics, genetic screening, and targeted therapy in oncology are considered essential components of the personalized approach. Additionally, current challenges, ethical considerations, and future prospects of this field are analyzed. The article concludes with reflections on the potential for developing personalized medicine in Uzbekistan.

Персонализированная медицина — это область здравоохранения, которая направлена на разработку диагностических, лечебных и профилактических стратегий на основе генетических характеристик, физиологического состояния и образа жизни каждого человека. В данной статье рассматривается концепция персонализированной медицины, её основные направления, преимущества и практическое применение. Области, такие как фармакогенетика, генетический скрининг и таргетная терапия в онкологии, считаются важными компонентами персонализированного подхода. Также проанализированы текущие проблемы, этические аспекты и перспективы развития этой области. В заключение представлены размышления о потенциале развития персонализированной медицины в Узбекистане. Introduction: Traditional methods in medicine were often based on a "one-size-fits-all" principle. That is, once a disease was diagnosed, the same treatment was applied to all patients. 8 85 International scientific journal ISSN: 2181-3906 «MODERN SCIENCE АND RESEARCH» 2025 VOLUME 4 / ISSUE 6 / UIF:8.2 / MODERNSCIENCE.UZ However, this approach was not always effective, as each individual has unique biological, genetic, and environmental features. Therefore, modern science increasingly emphasizes the necessity of an individualized approach. From these requirements, the concept of personalized medicine has emerged. The Concept of Personalized Medicine: Personalized medicine is a healthcare model that considers the patient’s genetic profile, immune status, environmental factors, lifestyle, and other individual variables to assess health and determine treatments. This approach is based on: 1. Genomic information (genetic tests) 2. Pharmacogenetics (drug response) 3. Biomarkers for disease detection 4. Individualized prevention and treatment plans This model enhances diagnostic accuracy, reduces adverse effects, and improves treatment outcomes. Key Directions 1. Pharmacogenetics Pharmacogenetics is a field of medicine that studies how an individual’s genetic makeup affects their response to drugs. As an integral part of personalized medicine, it helps determine the most appropriate drug type and dosage for each patient. Its core principle is that a drug may affect different people differently due to genetic differences. Drugs undergo metabolism through various biological pathways in the body. Enzymes, proteins, and transporters play key roles in these processes. Genetic variations in these components influence how a drug acts in the body. Some people genetically metabolize drugs quickly, while others process them slowly or not at all — leading to inefficacy or toxicity. Pharmacogenetic research focuses primarily on the cytochrome P450 enzyme family, especially CYP2D6, CYP2C9, and CYP2C19. Variations in these genes significantly affect drug metabolism. For example, changes in CYP2D6 can alter responses to pain relievers, cardiac medications, and a
