Huge Gaps in Use of Simple, Cheap and Proven Drugs

Huge Gaps in Use of Simple, Cheap and Proven Drugs

This is true in high income countries, like Canada, as well as middle and low income countries, say the international team of researchers who conducted the PURE (Prospective Urban Rural Epidemiological) study.

"Our study indicates a large gap in secondary prevention globally, with extremely low rates of use of proven therapies in middle and low income countries," said Doctor Salim Yusuf, lead author and professor of medicine of McMaster University's Michael G. DeGroote School of Medicine.

Secondary prevention includes the use of simple Aspirin, cholesterol-reducing drugs and blood pressure lowering drugs and diuretics to reduce the risk of an individual suffering a heart attack or stroke. All these drugs are proven, extremely safe and very inexpensive, Yusuf said.

"Even the use of simple, inexpensive and commonly available treatments such as Aspirin varied seven-fold in patients with heart attacks or strokes between low income countries and high income countries, whereas the use of statins varied 20-fold between these countries," the PURE study found. Yusuf said there is an "urgent need" for systematic approaches to understand and solve the causes of the large treatment gap in secondary prevention in the community globally.

Participants in the PURE study included 154,000 adults between 35 and 70 years old, of whom about 7500 had a history of heart disease or stroke, from 17 high, middle and low-income countries. Each person's use of medications was recorded, along with information about their age, sex, education, and key risk factors such as smoking, diabetes, hypertension and obesity.

Yusuf said the data are "disturbing and indicate a need for systematic efforts to understand why even inexpensive medications are substantially underutilized worldwide. This is a global tragedy and represents a huge wasted opportunity to help millions of people with heart disease at very low cost."

Some causes, they suggested, may be limited availability of these drugs in low and middle income countries, the relatively higher cost of even generic drugs, side-effects of drugs, lack of transportation, limited access to health care providers and lack of awareness of the need for lifelong therapy by both patients and their doctors. They could not explain why women in all settings receive fewer medications.
