An infection, heart surgery, or unknown causes might cause the pericardium (the lining surrounding the heart) to become irritated. Pericarditis is a type of irritation that causes acute, stabbing pain in the centre of the chest. Although it normally goes away after four to six weeks, some people have many attacks.
The FDA authorized a new medication for the treatment of recurrent pericarditis in March. It's called rilonacept (Arcalyst) and it works by targeting a chemical that has a role in the underlying inflammation that causes pericarditis. The drug is provided as a weekly injection that is self-administered. The medicine relieved unpleasant symptoms and reduced the likelihood of future flare-ups in a clinical trial. Redness or swelling at the injection site, as well as respiratory symptoms like a runny nose and cough, are all possible side effects.
