Nearly 2.9% of Medicines Tested in India Over Last 5 Years Failed Quality Standards — Here’s What the Data Reveals
A quiet but significant disclosure made in India’s Parliament this week has put the spotlight on the quality of medicines that millions of Indians consume every day.
The central government revealed that out of nearly 5 lakh drug samples tested over the last five years, a total of 14,342 samples — approximately 2.9% — were officially found to be “Not of Standard Quality (NSQ)”. The data was shared by Anupriya Patel, Minister of State for Health and Family Welfare, through a written reply in the Rajya Sabha on Monday.
Failure Rate Has Stayed Stubbornly Around 2.9%
What stands out in the government’s own figures is not just the number of failed samples — it is the consistency of the failure rate. Despite a steady increase in the volume of drug samples being tested each year, the proportion of substandard medicines has remained broadly unchanged at around 2.9%.
In simple terms: more medicines are being tested, but the same share keeps failing. That pattern points not to random lapses, but to a deeper, more systemic issue within India’s pharmaceutical supply chain.
What Does “Not of Standard Quality” Mean?
Under Indian law, a drug is declared NSQ when it fails to meet the quality, safety, or efficacy benchmarks prescribed under the Drugs and Cosmetics Act, 1940 — the foundational legislation governing how medicines are manufactured, sold, and distributed across India.
An NSQ medicine could mean several things:
The active ingredient is present in lower quantity than declared on the label
The drug is contaminated with foreign substances
It does not dissolve or absorb correctly in the human body
The potency has degraded due to poor storage or manufacturing conditions
In any of these cases, the medicine fails to do what it promises — and in some situations, it can actively harm the patient taking it.
