In a significant development that highlights the increasing scrutiny over the safety of pharma products, India's Central Drugs Standard Control Organisation (CDSCO) has identified 186 drugs and formulations as Not of Standard Quality (NSQ) in its surveillance report for May 2025. These identified drugs encompass widely prescribed drugs like paracetamol as well as diabetes drugs, triggering grave concerns over the safety of drugs in one of the world's largest pharmaceutical markets.The action, the CDSCO says, is its part of regular regulatory vigilance aimed at detecting and eliminating unsafe drugs in the market so that patients are not inadvertently left consuming substandard or spurious medicines.The list, published by the country's national drug regulator on 27 June, 2025, contains common drugs like paracetamol and insulin used to treat diabetes, prompting critical questions on drug safety, regulatory scrutiny, and public health in one of the biggest pharma markets in the world.The CDSCO's recent warning follows central and state drug testing laboratories in India reporting scores of samples from pharmacies and distribution centers across the country. Of the total 186 failed quality test samples, 128 were detected by state drug testing laboratories, and 58 by central labs. All this aggressive monitoring forms part of CDSCO's constant vigilance to ensure the quality of drugs being sold to Indian consumers.Of the 186 substandard drug samples, 128 were identified by state drug testing labs and 58 by central labs, as per the official notification. All these drugs failed one or more of the quality parameters such as potency, dissolution rate, microbial load, or content uniformity, and hence were not fit for use by patients.In a statement that released with the move, CDSCO sought to point out that one failed batch of drug is unique to that batch and does not always mean all batches of the same brand or product are unsafe. Still, the detection of even a single poor batch can have implications for public health, particularly in the case of life-saving and chronic disease drugs.The CDSCO also established that two of the Bihar drug samples were spurious, i.e., produced by unauthorized parties with the brand name of a different licensed company. These results suggest counterfeit operations in India's huge and intricate drug distribution system.The regulator has assured that the incidents are being investigated and action would be taken under the Drugs and Cosmetics Act and the accompanying rules.This is not a one-off case. CDSCO reported 900 samples as substandard and 20 as spurious in the year 2024 alone, all of them selected from pharmacies, hospitals, and distribution outlets throughout the nation.What Are "Not of Standard Quality" (NSQ) and Spurious Drugs?CDSCO defines NSQ as an occurrence of failure to satisfy one or more of the stipulated quality parameters during laboratory testing. The parameters would involve potency, purity, dissolution, and contaminants or impurities. Significantly, the regulator points out that a failed batch does not necessarily incriminate all the products of the same brand or company.Aside from NSQ medicines, the CDSCO also marked two samples from the state of Bihar as "spurious." These were discovered to have been produced by illegal manufacturers with the use of the brand name of another firm—a grave offense which is being investigated. Adulterated and spurious medicines are especially threatening since they can have the wrong or harmful ingredients and therefore directly threaten patient safety. How India Monitors Drug Quality?India's pharma industry is one of the biggest in the world, serving not just the domestic market but also exports to more than 200 nations. With such a huge market, maintaining drug safety is no small effort. The CDSCO, along with state regulators, regularly takes drug samples from sales and distribution points. The samples are tested thoroughly in the laboratory, and the findings are made available on the CDSCO portal on a monthly basis.This openness achieves several functions: it warns medical professionals and the general public to possible danger, raises responsibility on manufacturers, and preserves the level of trust for the healthcare system. In the words of Dr. Rajeev Singh Raghuvanshi, India's Drugs Controller General, only roughly 1.5% of drugs tested in recent surveys turned out to be less effective, indicating that the overwhelming majority of medicines available are safe. Still, a small proportion can add up to potentially great public health threats in view of India's population and the magnitude of drug use.Threats to Public Health and World Drug SupplyIndia has been commonly referred to as the "pharmacy of the world," exporting generic drugs to more than 200 nations. Any quality lapse not only impacts Indian consumers but also tarnishes world confidence in Indian pharmaceuticals. Paracetamol and anti-diabetics are consumed by millions — any compromise on their effectiveness or safety can be devastating health-wise.Substandard or counterfeit drugs are one of the greatest dangers to contemporary medicine," an independent pharmacovigilance expert in New Delhi said. "They may not treat the disease, may worsen patient outcomes, or lead to antimicrobial resistance."The public, clinicians, and policymakers need to address CDSCO notifications not as run-of-the-mill bureaucracy but as canary-in-the-coal-mines warnings of broader systemic problems in manufacturing regulation, supply chain integrity, and quality control procedures.What Can Healthcare Providers and Patients Do?Awareness is the best defense for patients. The CDSCO's medicine alert system seeks to inform consumers and healthcare providers about possible dangers of certain drugs. Patients must go see their doctors or pharmacists if they have issues with their medication and avoid buying drugs from unofficial sources.Healthcare professionals, on their part, must remain up to date on the current CDSCO reports and advisories, particularly when dispensing or prescribing high-risk drugs. Keeping an eye on the CDSCO portal regularly and being subscribed to alerts can help ensure that patients receive only safe and effective medicines. Patients must:Inquire about the batch number and manufacturer prior to taking prescribed drugs.Immediately report any side effects.Do not buy drugs from illegal online pharmacies.In addition, hospitals and states should institutionalize pharmacovigilance programs in order to identify adverse trends early.The CDSCO's forward-looking attitude—constant vigilance, open reporting, and rapid enforcement against violators—is reflective of India's seriousness in protecting public health. Nevertheless, the challenge persists. As the pharmaceutical sector continues its expansion, so must regulatory capability, laboratory facilities, and public awareness.
