Clinical research is part of healthcare science that collects evidence to establish a treatment. If you have ever taken any medication at all, then you have sampled clinical research. Research had to be done on that medication before it was available to you and others.The research is used to find medications for prevention, treatment, diagnosis or relieving symptoms of a disease. The term clinical research can be interchanged with the terms clinical study, clinical trial, research trial, research study or drug study–they all mean the same. At NCCR, clinical research often involves the study of asthma, allergy or COPD medications, but can involve medications for other diagnoses as well.
