The vertebral column is a collection of individual bones  called vertebrae that encase and protect thâ¦e spinal cord. The  vertebral column is divided into three parts: seven cervical (neck)  vertebrae at the top, twelve thoracic vertebrae in the midback, and  five lumbar vertebrae in the lower back.
Clopidogrel is used to prevent heart attacks and strokes in persons with heart disease (recent heart attack), recent stroke, or blood circulation disease (peripheral vascular disease).
Clopidogrel must be changed to an active form in your body so that it can treat your condition. Some people do not change clopidogrel to its active form in the body as well as other people. Because the medication does not work as well in these people, they may be at a higher risk of having a heart attack or stroke.
