Определение drug resistance в Английский Язык Английский Язык словарь
(Tıp, İlaç) Drug resistance is the reduction in effectiveness of a drug in curing a disease or improving a patient's symptoms. When the drug is not intended to kill or inhibit a pathogen, then the term is equivalent to dosage failure or drug tolerance. More commonly, the term is used in the context of diseases caused by pathogens
Property of a disease-causing organism that allows it to withstand drug therapy. In any population of infectious agents, some have a mutation that helps them resist the action of a drug. The drug then kills more of the nonresistant microbes, leaving the mutants without competition to multiply into a resistant strain. This situation is more likely if the drug is not taken properly (e.g., a course of antibiotics not completed, anti-HIV drug doses missed) or not prescribed properly (e.g., an antibiotic given for a viral disease). Resistance factors can also be transferred between species that infect the same body. The overprescription of antibiotics in humans and the addition of antibiotics to animal feed have accelerated the evolution of resistant strains of bacteria, making it increasingly difficult to fight off certain disease-causing organisms
Drug resistance is the result of microbes changing in ways that reduce or eliminate the effectiveness of drugs, chemicals, or other agents to cure or prevent infections
refers to the ability of cancer cells to become resistant to the effects of the chemotherapy drugs used to treat cancer
