Introduction to clinical trials

Home - Articles

Clinical trails evaluate the effectiveness and safety of medications or medical devices by monitoring their effects on large groups of people.

Participants:

All such trials are conducted on human volunteers in natural environments to avoid any discrepancies. The human volunteers who participate in the research treatments play a vital role in the advancement of medical technology.

Procedure for clinical trials:

When conducting a clinical trial the people who participate, apart from the volunteers, include doctors, nurses, clinical specialists and other medical professionals. The process of a clinical trial can be summarized in the following steps:

  • Initially the health statistics of the volunteer are documented in order to verify the changes that occur during and after the trial.
  • Next the participant is given instructions for the trial and the precautionary measures he/she is supposed to take.
  • Constant monitoring of the volunteer and the changes that occur throughout the duration of the trail.
  • Maintaining communication with the volunteer after the trial is completed.

Different types of clinical trials:

  • Treatment trials: Testing of treatments to be conducted, which include a combination of drugs or devices that can be used for treatment, or a newer approach to the surgeries and therapies for treatment of a particular ailment.
  • Prevention trials: Research to find better options for avoiding a medical problem among people who never had the particular medical problem before or to ensure that the problem never returns if already cured once. This research includes vitamins, medicines, minerals & lifestyle changes.
  • Diagnostic trials: Research to judge and find tests or procedures that are more viable for quick and safe treatment of a specific medical problem.
  • Screening trials: Research to determine more efficient ways to detect ailments and diseases.
  • Quality life trials: Research to find ways to improve the lives of people suffering from chronic diseases.
