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.

I was at the post office early that morning, hoping to be in and out in a short while.Yet, I 36 myself standing in a queue that went all the way into the hallway.I had never seen so many people there on a weekday.It seemed someone might have made an announcement, welcoming customers to carry as many 37 as they could and bring them in when I needed to have my own package 38 .The queue moved very slowly.My patience ran out and I got 39 .The longer it took, the angrier I became.When I got to the counter finally, I finished my 40 quickly and briefly, and then walked past the queue that was now extending past the front door.
"Excuse me," I said, trying not to be too pushy.Several people had to move 41 to make room for me to get to the 42 .
I stepped out, complaining about the 43 conditions.Thinking I was going to be late for my dentist appointment, I headed into the parking lot.
A woman was coming across the lot in my 44 .She was walking with determination, and each step sounded very heavy.I 45 that she looked as if she could breathe fire.It stopped me in my tracks.I 46 _ myself and it wasn't pretty.Had I looked like that? Her body language said that she was having a _47 day.My anger melted away.I wished I could wrap her in a hug but I was a 48 .So I did what I could in a minute 49 she hurried past me-I smiled.In a second everything changed.She was astonished, then somewhat 50 .Then her face softened and her shoulders 51 .I saw her take a deep breath.Her pace slowed and she smiled back at me as we passed each other.
I continued to smile all the way to my _52 .Wow, it's amazing what a simple smile can do.
From then on, I became aware of people's 53 and my own, the way we show our feelings.Now I use that _54 every day to let it 55 me that when facing the world, I can try a smile.
