Would you and your grandfather buy the same clothes? Probably not, but you might receive the same medicines and medical treatment when you get sick despite many differences. That's because even the world's best doctors don't yet fully understand how different people catch the disease and respond to the treatment.
The practice of medicine is highly reactive. Drugs and medicines we devise are tested over large populations and are prescribed using those statistics. But they work on some patients but not on each patient. Here traditional medicines lose their mark as every person's genetics is different from others and it's an important factor that affects health.
It's like a "one size fits all" medicine approach, giving the same treatment to those with the same illness. But this traditional approach has limitations because there is a whole lot of difference in each person's genetics and other factors, and it's important as it affects their health.
Personal medicine is a new idea evolving in healthcare. Personal medicine is a medical practice that differentiates people based on genetic information, age, and other factors.
Terms - personalized medicines, precision medicines, and P4 medicine are used interchangeably. It can maximize a patient's chances of better treatment if treatment is based on known factors. Personalized medicine is aimed at reducing costs as it is tailored according to the individual features of each patient. The arrival of personalized medicine is moving us towards more precise, predictable, and powerful health care that is specially made for the individual patient.
With growing knowledge of genetics and genomics - and how they encourage good health, disease, and drug responses in each person, personalized medicine allows doctors with - better disease prevention, more correct diagnoses, safer drug medicines, and more efficient treatments for the many diseases and conditions.
Tailoring health care to each person's unique genetic makeup - that's the promising idea behind precision medicine, also differently known as individualized medicine, personalized medicine, or genomic medicine. Moreover, personalized medicines aim to foretell the susceptibility of each patient to critical medical problems, by this the way it works to specify steps that may help in limiting or reducing the possibility of individual sufferance from a disease(s) and/ or medication side effect(s).
Here are some of the benefits of personalized medicine:
Advancements in personalized medicines will create a more unified treatment approach specific to a person and their genetics. Personalized medicines provide better drug development, better diagnosis with earlier intervention. Here are some applications of Personalized Medicines:
Today in Healthcare having an individual's genomic information can be important in the process of producing drugs as they await approval from the authorities for public use. With personalized medicines, treatment can be more specifically tailored to an individual and give insight into how their body will respond to the drug and if that drug will work based on their genome.
Theranostics is a personalized method for treating cancer, using similar molecules for both imaging (diagnosis) and therapy. The word theranostics is derived from the combination of the words therapeutics and diagnostics.
Radiotheranostics is a subspecialty of theranostics using similar pharmaceuticals for both imaging and therapy with radiation.
A lot of molecular-scale information about patients can be easily obtained through the use of genomics (microarray), proteomics (tissue array), and imaging (fMRI, micro-CT) technologies. Essentially, population genomics screening can be used to identify people at risk for disease, which can assist in preventative efforts.
Personalized medicine is an awesome opportunity to take a "one size fits all" method for diagnostics and drug therapy and turn it into an individual method. Genomics is playing a big role in the development of personalized medicine, 'cause it gives us a window in a very specific molecular way into those differences between us and allows the opportunity for making individual predictions about disease risk that can help somebody choose a prevention plan that is right for them. It also enables the possibility in some instances of picking the right drug at the right dose for the right person instead of the "one size fits all" approach to drug therapy. There is nothing wrong to say that there are plentiful advantages within this approach to medical care, with increased effectiveness and minimal side effects. Therefore, it could be argued that overall, the future of healthcare is personalized medicine.
