A new pain killer that is tolerable by a wider group of people is being launched in Britain today leading to hope that millions of patients suffering from chronic pain can now deal with their condition without any unpleasant side effects.
The pain killer drugs currently in the market cause a number of side effects in patients including constipation and vomiting. However recent clinical trials have shown that the new drug, known as Palexia, is tolerated by a larger percentage of the population and will be available in the market from today.
Marketed by Grunenthal in Europe, Palexia, which is the brand name for tapentadol, was found to produce unpleasant side effects in just over one third of elderly patients compared to more than 65 percent who used oxycodone.
Palexia has received a thumbs-up from St Bartholomew Hospital's consultant anaesthetist, Prof Richard Langford who said that the drug causes less number of side effects in patients. "Many patients with even the most severe chronic pain stop taking their treatment because the side effects are unbearable, even though their pain is better controlled", he said.
