Expired medicines

This refers to the letter " Safe use" (Jan 28) by Muhammad Bakar. The writer said that, nowadays multiple expired medicines are sold by the owners of stores. They never check the dates of the medicines and never throw them. Due to the expired medicines many patients are in trouble but yet no one seems serious regarding this sensitive matter and none of authorities pay any attention to this problem. So, why government doesn't take measures about this problem and why it is not arresting the expired medicines seller.
