Medicine
Medicine
is the art, science, and practice of caring for a patient and managing the diagnosis, prognosis, prevention, treatment or palliation of their injury or disease. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness.
Unlike physics or chemistry, medicine is not a pure science. When we call it an applied science, it implies only principles of pure science are applied in medicine. Even the results obtained from sophisticated tools may be different.
Brand names versus generics
Many medicines have at least 2 different names: the brand name – created by the pharmaceutical company that made the medicine. the generic name – the name of the active ingredient in the medicine.
A drug is any substance (with the exception of food and water) which, when taken into the body, alters the body's function either physically and/or psychologically. Drugs may be legal (e.g. alcohol, caffeine and tobacco) or illegal (e.g. cannabis, ecstasy, cocaine and heroin).
It is important to note that a vaccine is a drug. Like any drug, vaccines have benefits and risks, and even when highly effective, no vaccine is 100 percent effective in preventing disease or 100 percent safe in all individuals. Most side effects of vaccines are usually minor and short-lived.
Oxygen is one of the most widely used therapeutic agents. It is a drug in the true sense of the word, with specific biochemical and physiologic actions, a distinct range of effective doses, and well-defined adverse effects at high doses.
