Once-a-week pill for HIV 'ready for testing in people' Human trials of a once-a-week oral pill for HIV could start, after successful tests in pigs, claim US scientists.
The slow-release tablet could free patients from having to take daily medication, they say.
It looks like a normal capsule, but on reaching the stomach its coating dissolves and a special structure packed inside unfolds.
This 4cm (1.5in) star-shaped scaffold stays in the stomach for seven days, steadily releasing its cargo of drugs.
More tests in other mammals, including monkeys, are recommended but the researchers say trails in people could begin within two years. BBC News
