What is 2012 Pakistan Fake Medicine Crisis?

Legal Definition
During late January 2012, a fake medicine crisis at the Punjab Institute of Cardiology (PIC) hospital in the Lahore region of Punjab, Pakistan, claimed the lives of over 100 heart patients. According to various reports, the incident involved patients who had been receiving treatment at the hospital and had been prescribed with counterfeit antihypertensive medicines. The spurious medicine(s) triggered a serious adverse reaction by depositing itself in the bone marrow and ending the body's resistance. The generation of white blood cells stopped in the body. Among the symptoms of the disease were a severe chest infection, change in skin colour/pigmentation, low platelet count and blood vomiting.

Suspect drugs include isotab (isosorbide nitrate), lipitor (atorvastatin calcium), cardiovestin (simvastatin), alfagril (clopidogrel), concort (amlodipine), and soloprin (aspirin).

The medicines were being distributed by the hospital free of charge mainly to poor people. The total number of people who may be at risk after taking medicine from the hospital may be as high as 46,000 according to one report.
