Deputy chief minister Brajesh Pathak who also holds the health portfolio, has ordered a probe into the issue of expired medicines worth Rs 50 lakh found stocked at Dr Ram Manohar Lohia Institute of Medical Sciences in Lucknow on Thursday. The minister reached Lohia institute campus on Thursday and started looking for expired medicines right from the drug distribution counters. He also scanned records kept in the store room. During his inspection for around 45 minutes, he finally counted 322 pages having a list of expired medicines worth Rs 50 lakh. Irked over the issue, the minister asked about who was responsible for this. He also sought explanation as to why those medicines could not be returned back to the manufacturing firms to get other medicines in exchange. But none of the officials, including the director of the institute could give any satisfactory reply to his query. In all, a list of 2,48,668 expired medicines were found that were kept there for over the last 5 years. A video clip from the inspection of the drug store by Pathak revealed that the expiration of just about 5,000 medicines will cost the state exchequer around Rs 50 lakh.
