Aspirin
Aspirin is one of the oldest drugs still in common use. However, the reasons for its use have changed considerably in modern times. Its traditional use in treating headaches, fevers and arthritic aches and pains has been largely replaced by newer preparations. But aspirin now has an important role in preventing heart attacks, strokes and, according to research in the US, bowel cancer.
Aspirin has an effect on blood, making it 'thinner' and less likely to clot. In the past this has been a problem for regular users of the drug because of the potential for aspirin to cause bleeding, and even ulcers, in the stomach.
However this ability to reduce blood clotting is put to good use in some people at risk of, or recovering from, heart attacks. A low dose of 100 mg (one third of a standard aspirin) every day has been shown to reduce the likelihood of future attacks. Likewise in some people the incidence of stroke may also be reduced by a similar dose.
Studies in the US have suggested that long-term (at least 10 years') use of aspirin can reduce the chances of developing cancer of the large bowel. The reason for this protective effect is not clear.
Aspirin is not suitable for everyone. But those middle-aged and over (especially if they still smoke) should discuss with their doctor the possible benefits to them of a small daily dose of aspirin.
