Hi, my mother is suffering from cardiac aneurysm and her heart size becomes large. Doctor first suggested for surgery but as she is very weak and her age above 60, doctor told me it will very dangerous and chance will be 15 percent. He prescribed some medicines which mainly drogs used for thinning the blood, painkiller, to correct the irregular rhythm of heart. But due to biggger size of heart which affects the function of lungs, she is suffering from severe cough for which doctor prescribed to use corex. As corex is banned now I am unable to get it. So, I request u sir please prescribe a cough syrup equivalent to corex
