Australian researchers have come one step closer to understanding how the rhythm of the heartbeat is controlled and why many common drugs, including some antibiotics, antihistamines and anti-psychotics, can cause a potentially fatal abnormal heart rhythm.
It is estimated around 40-50% of all drugs in development will block one of the main ‘channels’ that carries electricity in the heart and, as a result, can cause heart rhythm problems called cardiac arrhythmias. Most sudden cardiac deaths are caused by cardiac arrhythmias.
Since 1996, nine drugs have been withdrawn from the market or had their use severely restricted due to this serious side effect.
