Drug Bans in India: A Deep Dive into the Medicines Removed for Safety and Health?

The pharmaceutical industry is the backbone of modern healthcare, ensuring the availability of drugs for the prevention and treatment of diseases. However, not all medicines stand the test of time. Some drugs, initially approved for public use, later exhibit harmful effects, leading to regulatory intervention and eventual bans. In India, where healthcare regulations aim to balance innovation and safety, hundreds of medicines have been banned to safeguard public health.

This article dives into the intricate world of banned medicines in India, exploring the reasons, processes, and implications. We also provide an updated list and tips for ensuring safe drug use.

Why Are Medicines Banned in India?

Medicines are banned when their risks outweigh their benefits. While some drugs are banned during clinical trials, others are removed from the market after being widely used due to post-marketing safety concerns. Here are the primary reasons:

• Adverse Drug Reactions (ADRs): Unexpected severe side effects that compromise patient safety, including organ damage, severe allergies, or death.

• Toxicity Issues: Long-term use leading to organ toxicity (e.g., liver, kidney, or cardiac toxicity).

• Ineffectiveness: Lack of evidence supporting a drug's therapeutic claims, making it redundant or unsafe.

• International Safety Alerts: Drugs banned in developed nations due to safety concerns often come under scrutiny in India.

• Irrational Combinations: Fixed-dose combinations (FDCs) with ingredients that interact adversely or serve no additional therapeutic purpose.

Regulatory Framework for Drug Bans in India!

The Central Drugs Standard Control Organization (CDSCO) and the Drug Controller General of India (DCGI) regulate medicines in India. The regulatory framework includes

• Approval Process: Drugs undergo preclinical trials, human clinical trials, and post-marketing surveillance before approval.

• Continuous Monitoring: Once a drug enters the market, adverse event reporting systems track its safety.

• Expert Panels: Recommendations from medical and pharmaceutical experts guide regulatory decisions.

• Publication of Notifications: Once banned, CDSCO releases public notices and informs healthcare professionals.

How Many Medicines Are Banned in India?

As of December 2024, the Indian government has banned a total of 344 fixed-dose combination (FDC) drugs, along with several single-drug formulations, to safeguard public health. These bans are enforced by the Central Drugs Standard Control Organisation (CDSCO) under the Ministry of Health and Family Welfare.

Recent Developments

• In August 2024, the Ministry issued a significant notification prohibiting 156 FDCs, including commonly used antibiotics, painkillers, and multivitamins. This action followed recommendations from an expert panel that found no therapeutic justification for these combinations and identified potential health risks.
