In continuation of my update COX-2
A class of drug for treating arthritis - all but shelved over fears about side effects - may be given a new lease of life, following the discovery of a possible way to identify which patients should avoid using it.
The new study, led by Imperial College London and published in the journal Circulation, sheds new light on the 10-year-old question of how COX-2 inhibitors - a type of non-steroidal anti-inflammatory drug (NSAID) - can increase the risk of heart attack in some people.
NSAIDs - which include very familiar drugs such as ibuprofen, diclofenac and aspirin - are widely-used treatments for debilitating inflammatory conditions such as arthritis as well as being used for general pain relief worldwide. NSAIDs are also being investigated for their potential to prevent cancer. COX-2 inhibitors, which include Vioxx and Celebrex, were developed in the 1990s to avoid the risk of stomach ulcers caused by some NSAIDs, but after they were linked to an increased risk of heart attacks, they rapidly fell out of favour and some brands, including Vioxx, were withdrawn.
The new study, in mice and human volunteers, was led by Professor Jane Mitchell and Dr James Leiper. Professor Mitchell, from the National Heart and Lung Institute at Imperial, said:
