Personalized medicine: Time for One person, one medicine

Abstract

It’s becoming clearer that medicine is not one-size-fits-all. The problem with the traditional or present way of medical treatment is that they are created for and tested on a large group of people. The medicines are prescribed so broadly that they don’t work for everyone. Some drugs work very well for certain people and some not. In ancient times, medicine was practiced according to the signs and symptoms presented by the patient and were solely based on the individual knowledge of the physician and thus were called intuition medicine. Nowadays, medicine is based on the evidence produced by scientific research, including clinical trials, which is designated as evidence-based medicine. In the future, medicine will be practiced according to algorithms that will take into consideration the patient's characteristics, such as their genome, epigenetics, and lifestyle, constituting personalized medicine. Doctors use information about you -- your genes, lifestyle, and environment -- along with the characteristics of your disease to select treatments that are most likely to work for you. Health care has transmuted since the decline in mortality caused by infectious diseases as well as chronic and non-contagious diseases, with a direct impact on the cost of public health and individual health care. The evolution of medicine has increased the life expectancy of humans. Personalized medicine is the new way of thinking about medicines. In this review, we will see how Personalized medicine will transform healthcare, how Artificial intelligence and personalized medicine working together towards better healthcare, personalized medicine in the pharmaceutical industry, its vision for the future, and its application in various diseases.
