LONDON (Reuters) — Children are dying for lack of drugs tailored to their needs, according to the World Health Organization (WHO), which launched a global campaign on Thursday to promote more research into child medicine. More than half of the drugs currently used to treat children in the industrialized world have not been specifically tested on youngsters. The problem is even worse in developing countries where price remains a major barrier and 6 million children die each year from treatable conditions. In the case of HIV/AIDS, the few existing pediatric therapies（儿科的疗法）developed for children generally cost three times more than adult ones. As a result, clinicians lack clear guidelines on the best drug to use and often have to guess at the correct dose. Fortunately, the WHO has drawn up the first international List of Essential Medicines for Children, containing 206 products considered safe for children. “But a lot remains to be done. There are priority medicines that have not been adapted for children’s use or are not available when needed,” said Dr Hans, the U.N. agency’s director of medicines policy and standards. Medicines that need to be adapted to children’s needs include many antibiotics, pain drugs as well as combination pills for HIV/AIDS, tuberculosis and malaria. The agency is building an Internet entrance linking to clinical trials carried out in children and will launch a Web site with the information early next year. Testing medicines on children has always been a controversial issue, since good ethical（伦理的）practice requires informed agreement from people participating in clinical trials, which is difficult to obtain in the case of children. As a result, research-based drug companies have been wary of developing child-friendly medicines and general companies have been slow to produce them at lower cost. In an attempt to deal with the issue, both Europe and the United States now have special rules offering extended patent protection for drugs that have been tested on children. 小题1:Which of the following is the best title of the passage?
