Four of the six drugs supplied to Delhi government hospitals failed the dissolvability test, affecting their efficacy. Sodium valproate, Levetiracetam, Amlodipine, and Cephalexin fell short on the dissolvability parameter, impacting their rate of absorption. The drugs are used to treat epilepsy, anxiety, high blood pressure, and infections. Additionally, Amlodipine had high impurity levels, which could harm health with long-term use. The Delhi government has ordered the withdrawal of non-compliant medicines from the market. The case of sub-standard medicines has been sent to the CBI for investigation.
