A new pill that reduces cough frequency by 75 per cent could be available within two to three years, experts have revealed. A clinical trial led by Manchester University looked into a twice-a-day tablet to treat coughs. It's the first medication designed to the treat the issue in 50 years, and works by blocking receptors on the throat nerve, which set off the cough reflex. As a result, the cough response is muted. In the trial, 24 patients who took the pill for two weeks saw their cough reduced by 75 per cent, whereas a previous study which looked into dextromethorphan, found that cough medicines, only reduced the frequency by 12 per cent. "Some people have a persistent tickly cough caused by sensitivity of the cough nerve," study leader Professor Jaclyn Smith said. "We have shown real progress in being able to stop that. We plan to start looking at people with normal coughs as well." The pill is currently being developed in the US, and in time it’s hoped the drug will be available to people suffering from the common cold.
