Essential medicines

The **List of Essential Medicines** is a listing of drugs compiled by the World Health Organization (WHO). The medicines on the list cover the basic needs of a society, and they should be affordable and easy to get, according to the WHO.

The list was first published in 1977. It is reviewed every two years. In 2023, the WHO published the 23rd version of its List of Essential Medications.

### Recommendations

The List also recommends which drugs should be used first to treat certain problems. For example, in its section on anti-infective medications, the List recommends using doxycycline as the first-choice treatment for cholera.

## Concerns

There are two major problems with the list: First, there are a number of diseases which mainly occur in developing countries. Many people there cannot afford to pay high prices for drugs, which means pharmaceutical companies are not interested in developing new drugs for such diseases. Examples for such diseases are malaria or tuberculosis. The second problem is that certain drugs on the list are patented, and they are often expensive. Examples for the second kind of drugs are those used to treat AIDS.

According to a study done by the world bank, about a third of the world's population does not have access to these drugs.
