Two more heart patients, after consuming the suspicious medicines, lost their lives Tuesday, pushing the overall death toll to 121 in Punjab. The string of deaths spurred by the dubious medicines of Punjab Institute of Cardiology (PIC) could not be stemmed despite all the frenzied efforts by the government of Punjab. According to sources, Central Drug Laboratory of Karachi declared one of the seven PIC medicines as substandard. Meantime, the investigations under Punjab&rsquo ; s aegis also revealed that some PIC officials are involved in the scam as some deficient medicines were changed without keeping back their records.
