Medical science is nothing , but trying hard all possibilities. Most innovations die .Only a fraction will survive .
That does not mean we should not try ! The greatness is in accepting the failure. The wonder drug which was an analogue of human atrial naturetic peptide (BNP) Nesiritide , died a peacful death on July 7th 2011 .
Long before , in year 2005 , Eric Topal in a hard hitting Editorial of NEJM wanted to hang this drug .
But it was a case of prolonged death sentance .

Should we pity with the drug companies and forgive them for delaying it’s exit , enable them recover the cost involved .
Meanwhile , Nesiritide might have died , the concept of BNP analogues may need to be explored further.
