NICE restricts clopidogrel and dipyridamole

Vascular occlusion can lead to heart attacks and strokes |
Patients who have experienced a stroke or heart attack, or who have symptomatic peripheral arterial disease, can be treated with the antiplatelet drug clopidogrel (Plavix) but only if they cannot tolerate aspirin, the National Institute for Health and Clinical Excellence announced this week.
NICE also recommends that modified-release dipyridamole can be used in
combination with aspirin to prevent strokes and heart attacks. Such therapy
is approved for a period of two
years from a patient’s most recent vascular event. Thereafter,
preventive therapy should revert to standard care.
A spokeswoman for the British Cardiac
Patients Association said that
the organisation was disappointed by the guidance, which, it said, placed
too much emphasis on the use of aspirin to prevent heart attacks and
strokes. This view was echoed in a statement issued by sanofi-aventis
and Bristol-Myers Squibb, co-developers of Plavix in the UK.
