General Dhiraj Seth Unveils ‘VIJAY’ Vision for the Indian Army

GS Paper 3 — Internal Security | Defence Modernisation

Why in News

General Dhiraj Seth, who took over as the 31st Chief of the Army Staff (COAS) on 30 June 2026 succeeding General Upendra Dwivedi, outlined his roadmap for the Indian Army through the acronym ‘VIJAY’, addressing reporters after receiving a guard of honour at South Block on 1 July 2026. The roadmap is aligned with the Ministry of Defence’s Decade of Transformation (2023–2032) and aims to build a digitised, technology-enabled, self-reliant, and multi-domain capable force.

Static Background — The Office of the Chief of the Army Staff

• The COAS is the professional head and highest-ranking officer of the Indian Army, a four-star General appointed by the President of India on the advice of the Union Government, and is the principal military adviser to the Defence Minister and the Government on Army matters.
• General Seth is an alumnus of the National Defence Academy, Khadakwasla, and was commissioned into the 2nd Lancers (Armoured Corps) in December 1986. He is the 7th COAS from the Armoured Corps and previously served as Vice Chief of the Army Staff and General Officer Commanding-in-Chief of both the Southern Command and South Western Command — among the few officers to have commanded two operational Army commands along the western front.
• The Indian Army is one of three professional wings of the Indian Armed Forces (alongside the Navy and Air Force), under the overall authority of the President as Supreme Commander, with the Ministry of Defence exercising civilian control. Tri-service jointness is being institutionalised through structures such as the Department of Military Affairs and the Chief of Defence Staff (CDS), created in 2019.
• The Decade of Transformation (2023–2032) is a Ministry of Defence roadmap, envisioned under Defence Minister Rajnath Singh, for modernisation and restructuring of the armed forces to meet future battlefield requirements, including theatrisation, indigenisation, and technology absorption.

The ‘VIJAY’ Roadmap — Five Pillars

Letter	Pillar	Focus
V	Vigilance	Heightened operational readiness and constant alertness along India’s borders to counter evolving security dynamics.
I	Innovation & Transformation	Integration of modern doctrine, cutting-edge technology, and rapid capability development for the changing character of warfare.
J	Jointness & Integration	Deeper structural synergy among the Army, Navy and Air Force, and military-civil fusion via a Whole-of-Nation approach toward Viksit Bharat 2047.
A	Atmanirbharta	Absolute commitment to indigenisation under the principle “Winning Our Wars with Indigenous Solutions.”
Y	Yodha First	Human capital development — training standards, technological skilling, and welfare for Agniveers, veterans, and Veer Naris.

The ‘JAI’ Foundation

General Seth stated that his priorities under VIJAY draw from the Prime Minister’s guiding mantra for the armed forces, ‘JAI’ — standing for Jointness, Atmanirbharta, and Innovation — describing his own motto as “JAI se VIJAY” (from JAI to victory). He described the Indian Army as a combat-ready and battle-hardened force, and paid tribute to soldiers who laid down their lives in service of the nation.

The VIJAY roadmap signals continuity with the Army’s ongoing modernisation drive rather than a break from it, embedding technology absorption, jointness, and indigenisation within a single guiding framework. Its success will depend on how effectively these five pillars translate into budgetary allocation, procurement reform, and tri-service integration over the coming decade.

Prelims Pointers

• COAS = Chief of the Army Staff, the Army’s highest-ranking officer; General Dhiraj Seth is the 31st COAS, succeeding General Upendra Dwivedi.
• VIJAY = Vigilance, Innovation & Transformation, Jointness & Integration, Atmanirbharta, Yodha First — General Seth’s five-pillar roadmap for Army modernisation.
• JAI = Jointness, Atmanirbharta, Innovation — the Prime Minister’s guiding mantra for the armed forces, which General Seth cites as the foundation of VIJAY.
• Decade of Transformation = Ministry of Defence roadmap (2023–2032) for modernisation and restructuring of India’s armed forces.
• Chief of Defence Staff (CDS) = a single-point military adviser role created in 2019 to head the Department of Military Affairs and drive tri-service jointness (distinct from the COAS, who heads only the Army).
• General Seth is the 7th COAS from the Armoured Corps and an alumnus of the National Defence Academy, Khadakwasla.

Practice Mains Question

The new Army Chief’s ‘VIJAY’ roadmap places equal emphasis on technology, jointness, and self-reliance. Discuss the significance of these priorities for India’s military modernisation in the context of the Decade of Transformation (2023–2032).

INS Trikand Foils Piracy Attempt on MV Golden Arsenal in the Gulf of Aden

GS Paper 3 — Internal Security | GS Paper 2 — International Relations

Why in News

On 1 July 2026, the MV Golden Arsenal, a St Vincent and the Grenadines-flagged bulk carrier with 21 crew members (including one Indian national) carrying critical cargo for India, reported an attempted pirate attack approximately 300 nautical miles east-northeast of Djibouti in the Gulf of Aden. The crew took refuge in the ship’s citadel and alerted authorities through the Information Fusion Centre – Indian Ocean Region (IFC-IOR). The Indian Navy’s Talwar-class stealth frigate INS Trikand responded, prompting the attackers to flee; a Marine Commando (MARCOS) team subsequently boarded and sanitised the vessel with support from a P-8I maritime patrol aircraft, finding no intruders. The vessel, which sustained bridge damage, was declared safe and resumed its voyage.

Static Background — Gulf of Aden

• Location: An extension of the Indian Ocean lying between the Arabian Peninsula (Yemen) to the north and the Horn of Africa (Somalia, Socotra Islands) to the south, bounded by the Arabian Sea to the east and Djibouti to the west.
• Connectivity: Links to the Somali Sea via the Guardafui Channel and to the Red Sea through the Strait of Bab el-Mandeb — making it a critical chokepoint on the Asia–Europe shipping route.
• Major ports: Aden (Yemen), Djibouti City (Djibouti), Berbera and Zeila (Somaliland), Bosaso (Somalia).
• Economic importance: Around 10% of global seaborne petroleum and over USD 110 billion of India’s trade pass through the Gulf of Aden.
• Threats: Piracy, armed attacks on merchant vessels, illicit trafficking, terrorism, and spillover from regional conflicts (notably instability in Yemen and Somalia).

India’s Anti-Piracy Role

• The Indian Navy has maintained a continuous anti-piracy presence in the Gulf of Aden since 2008, positioning itself as a “preferred security partner” and first responder for merchant shipping in the Indian Ocean Region (IOR).
• The Information Fusion Centre – Indian Ocean Region (IFC-IOR), based at INS Kattabomman (Gurugram), is a maritime domain awareness hub that coordinates information-sharing among partner nations to counter piracy, trafficking, and other maritime threats.
• INS Trikand had earlier, in mid-June 2026, deterred a suspected piracy attempt on another merchant vessel, MV Fareeda 5, in the Western Indian Ocean — underlining a sustained Indian Navy deployment in the region.
• The International Maritime Organization (IMO) has separately appealed for urgent cooperation to free the crews of three vessels still held by Somali pirates, including MT Honour 25, highlighting a broader resurgence of piracy risk linked to instability in Yemen and Somalia.

The swift, multi-asset response — a stealth frigate, MARCOS commandos, and P-8I aerial surveillance, coordinated through the IFC-IOR — illustrates the maturity of India’s maritime security architecture in the Indian Ocean Region. However, the continuing captivity of other vessels’ crews underscores that resurgent Somali piracy is a persistent, not isolated, security challenge, likely to require sustained naval presence alongside political and law-enforcement action ashore.

Prelims Pointers

• INS Trikand = a Talwar-class stealth frigate of the Indian Navy, capable of embarking helicopters; part of India’s sustained Gulf of Aden deployment.
• MARCOS = Marine Commandos, the Indian Navy’s special forces unit for maritime counter-terrorism and anti-piracy boarding operations.
• IFC-IOR = Information Fusion Centre – Indian Ocean Region, India’s maritime domain awareness and information-sharing hub for the IOR.
• Citadel = a reinforced safe room on merchant vessels where crew can shelter during a piracy attack while awaiting rescue.
• Strait of Bab el-Mandeb = connects the Gulf of Aden to the Red Sea; a key global chokepoint for shipping and energy trade.
• India has maintained anti-piracy naval deployment in the Gulf of Aden since 2008.

Practice Mains Question

Discuss the strategic significance of the Gulf of Aden for India’s trade and energy security, and evaluate the role of the Indian Navy in countering piracy in the Indian Ocean Region.

GAGAN — India’s Satellite-Based Augmentation System Achieves a Landing Milestone

GS Paper 3 — Science & Technology | Space

Why in News

In June 2026, the Directorate General of Civil Aviation (DGCA) supervised India’s first satellite-based landing system (SLS) approach on a commercial jet aircraft using GAGAN (GPS Aided GEO Augmented Navigation). The landmark approach was performed by an IndiGo Airbus A320 at Udaipur airport on 27 June 2026, extending GAGAN-guided precision landings beyond turboprop aircraft to mainline jet operations for the first time.

Static Background — What is GAGAN?

• GAGAN is India’s indigenous Satellite-Based Augmentation System (SBAS), jointly developed by the Indian Space Research Organisation (ISRO) and the Airports Authority of India (AAI), operational since 2015.
• Why it is needed: Standard GPS signals can be distorted by the ionosphere and other atmospheric effects, introducing positioning errors unacceptable for precision aviation. GAGAN corrects these errors in real time and issues integrity information — alerts telling pilots when a GPS signal is unreliable for navigation.
• GAGAN vs GPS vs NavIC: GPS provides raw positioning; GAGAN is not an independent satellite constellation but a correction layer that improves GPS accuracy and reliability for aviation. NavIC (Navigation with Indian Constellation) is India’s separate, independent regional satellite navigation system providing positioning, navigation and timing (PNT) services over India and up to 1,500 km beyond its borders.
• Global standing: GAGAN places India among a select group of nations — alongside the USA (WAAS), Europe (EGNOS), and Japan (MSAS) — operating a certified SBAS, and is interoperable with all three. It is also the first SBAS certified for the equatorial region, a technically demanding environment due to greater ionospheric disturbance.

Architecture

• 15 Indian Reference Stations (INRES) across the country continuously track GPS signals and flag positional errors.
• 2 Indian Master Control Centres (INMCC) process these discrepancies in real time and generate correction data.
• 3 Indian Land Uplink Stations (INLUS) transmit the correction data to satellites.
• 3 geostationary satellites — GSAT-8, GSAT-10, and GSAT-15 — carry GAGAN payloads and broadcast the corrected, integrity-checked signal to aircraft receivers.

The Udaipur Milestone

• The IndiGo A320 used a Localiser Performance with Vertical Guidance (LPV) approach, achieving positional accuracy of roughly 3 metres and vertical guidance down to 200 feet above ground — about ten times more precise than standard GPS.
• Unlike the ground-based Instrument Landing System (ILS), which is costly to install and largely confined to major airports, LPV approaches require no expensive ground infrastructure, making precision landings feasible at smaller, regional airports even in poor visibility.
• As of May 2026, AAI had published 23 LPV approach procedures nationally, with a target of over 40 by the end of 2026.
• DGCA has mandated GAGAN-compatible equipment on all new aircraft registrations in India from 1 July 2021.

Applications Beyond Aviation

Sector	Use of GAGAN
Maritime Navigation	Accurate positioning in coastal and offshore waters.
Road Transport & Highways	Intelligent transport systems and fleet management.
Railways	Improved operational efficiency and safety.
Disaster Management	Accurate location tracking during emergencies.
Defence & Security	Strengthened navigation for defence operations.
Surveying & Mapping	Improved accuracy of land surveys and geospatial mapping.

By extending satellite-guided precision landings to mainline jets, the Udaipur approach demonstrates that GAGAN has moved from a certified-but-underused capability to an operationally mature system. Its greatest promise lies in regional connectivity: enabling safe landings at smaller airports lacking costly ground infrastructure, thereby supporting schemes such as UDAN while reducing India’s dependence on foreign navigation systems.

Prelims Pointers

• GAGAN = GPS Aided GEO Augmented Navigation; India’s SBAS, developed by ISRO and AAI, operational since 2015.
• SBAS = Satellite-Based Augmentation System; corrects and adds integrity information to GPS signals — does not itself determine position independently.
• NavIC = India’s independent regional satellite navigation system (unlike GAGAN, which augments GPS rather than replacing it).
• LPV approach = Localiser Performance with Vertical Guidance; a satellite-guided precision landing procedure enabled by GAGAN, needing no ground-based ILS infrastructure.
• Equivalent global SBAS: WAAS (USA), EGNOS (Europe), MSAS (Japan) — all interoperable with GAGAN.
• GAGAN payloads fly on GSAT-8, GSAT-10, GSAT-15; the ground segment has 15 reference stations, 2 master control centres, 3 land uplink stations.
• GAGAN is the world’s first SBAS certified for the equatorial region.

Practice Mains Question

What is a Satellite-Based Augmentation System? Discuss the significance of GAGAN for India’s aviation safety and regional connectivity, with reference to its recent extension to commercial jet operations.

GS Paper 3  |  150 words  |  10 marks

Prelims Practice MCQ

Assertion (A): GAGAN improves the accuracy and reliability of GPS signals for aviation.
Reason (R): GAGAN is an independent satellite constellation that determines aircraft position without reference to GPS.

Which one of the following is correct in respect of the above statements?

• (a)Both A and R are true, and R is the correct explanation of A
• (b)A is true, but R is false
• (c)A is false, but R is true
• (d)Both A and R are false

Correct Answer: (b)

Assertion (A) is correct — GAGAN, a Satellite-Based Augmentation System, improves the accuracy and integrity of GPS signals. Reason (R) is false — GAGAN is not an independent positioning constellation like GPS or NavIC; it works as a correction layer on top of existing GPS signals and cannot determine position on its own.

Article 04

Government Brings Stem Cell, Gene Therapies Under Central Licensing

GS Paper 2 — Health Policy | Regulatory Bodies

Why in News

The Central Government has notified the Drugs (Eighth Amendment) Rules, 2026, amending the Drugs Rules, 1945 to bring cell or stem cell-derived products, gene therapeutic products, and xenografts under the Centrally License Approving Authority (CLAA) framework. The amendment, which came into force on 29 June 2026 following consultation with the Drugs Technical Advisory Board (DTAB), revises Rules 75, 75A, 76 and 76A of the Drugs Rules, 1945, and aims to strengthen regulatory oversight of advanced and rapidly evolving medical technologies.

Static Background — The CLAA Framework

• The Centrally License Approving Authority (CLAA) is a joint licensing mechanism functioning under the Central Drugs Standard Control Organisation (CDSCO), empowered by the Drugs and Cosmetics Act, 1940. It ensures certain critical drugs and biological products are regulated jointly by Central and State Licensing Authorities, rather than by state authorities alone.
• Categories already covered by CLAA before this amendment: vaccines, large-volume parenterals (IV solutions above 100 ml), and recombinant DNA (r-DNA)-based medicines.
• CDSCO, headed by the Drugs Controller General of India (DCGI), functions under the Ministry of Health and Family Welfare and is India’s national regulatory authority for drugs and medical devices, working alongside State Licensing Authorities in a federal drug-regulation structure.

Categories Newly Added to CLAA

Category	Description	Key Application
Cell/Stem Cell-derived Products	Stem cell-based regenerative treatments; includes CAR-T cell therapies.	Treatment of blood cancers such as leukemias and lymphomas.
Gene Therapeutic Products	Gene replacement and gene-editing products.	Genetic disorders and various types of cancer.
Xenografts	Animal tissue-derived products, e.g. heart valves.	Transplantation in cardiology and orthopaedics.

Rationale and Significance

• These technologies are highly complex, specialised, and rapidly evolving, requiring enhanced regulatory scrutiny to ensure patient safety — unlike conventional drugs with established, standardised manufacturing processes.
• Joint Central-State oversight is intended to ensure uniformity of regulatory standards across states, preventing a fragmented approval landscape for high-risk advanced therapies.
• The move aligns India’s regulatory framework with global best practices for regulating cell and gene therapies, while aiming to promote innovation and quicker, safer adoption of cutting-edge medical technologies in the healthcare and life sciences sectors.

Bringing cell, gene, and xenograft-based therapies under joint Central-State licensing closes a regulatory gap that had left some of India’s fastest-growing and highest-risk medical technologies without the same tiered oversight applied to vaccines and biologics. Effective implementation will depend on CDSCO and State Licensing Authorities building the specialised technical capacity needed to evaluate these advanced therapies.

Prelims Pointers

• CLAA = Centrally License Approving Authority; a joint Central-State licensing mechanism under CDSCO for high-risk drugs and biologics.
• Drugs (Eighth Amendment) Rules, 2026 = amends Rules 75, 75A, 76 and 76A of the Drugs Rules, 1945; in force from 29 June 2026.
• CDSCO = Central Drugs Standard Control Organisation, India’s national drug regulator under the Ministry of Health and Family Welfare, headed by the Drugs Controller General of India (DCGI).
• Xenograft = a tissue or organ transplanted from an animal into a human (e.g. porcine heart valves).
• CAR-T cell therapy = a gene-modified cell therapy used to treat blood cancers such as leukemia and lymphoma; now covered under CLAA.
• Categories previously under CLAA: vaccines, large-volume parenterals (IV solutions >100 ml), r-DNA-based medicines.

Practice Mains Question

Discuss the significance of bringing advanced cell and gene therapies under the Centrally License Approving Authority (CLAA) framework. What regulatory challenges does India face in overseeing such emerging medical technologies?

GS Paper 2  |  150 words  |  10 marks

Prelims Practice MCQ

Consider the following statement regarding the Centrally License Approving Authority (CLAA) framework: "The CLAA framework, established under the Drugs and Cosmetics Act, 1940, provides for the exclusive licensing of specified critical drugs and biologics by the Central Government, without any role for State Licensing Authorities." Is this statement correct?

• (a)Correct
• (b)Incorrect

Correct Answer: (b) Incorrect

The CLAA framework provides for joint regulatory supervision by both Central and State Licensing Authorities, not exclusive Central licensing. The framework is meant to ensure uniformity of standards nationwide through this shared oversight, not to remove the states’ role.

Article 05

Assam’s Nameri Tiger Reserve Records a Four-Fold Rise in Tiger Population

GS Paper 3 — Environment & Biodiversity Conservation

Why in News

Assam’s Forest and Environment Minister Jayanta Malla Baruah announced that the tiger population at the Nameri Tiger Reserve in Sonitpur district has quadrupled in three years — rising from 3 tigers in 2022 (All India Tiger Estimation) to 12 by the end of 2025, an estimate validated by the Wildlife Institute of India (WII). The Minister also highlighted the return of tigers to the Sonai-Rupai Wildlife Sanctuary, Nameri’s satellite core, after more than two decades of local extinction there.

The pasted source material states Nameri Tiger Reserve’s area as 344 sq. km; this figure is carried here as reported in the source and has not been independently reconciled against other published area breakdowns for the reserve (core, satellite core, and buffer zones combined).

Static Background — Nameri Tiger Reserve

• Located in the northern part of Sonitpur district, Assam, at the foothills of the Eastern Himalayas; it is a national park, tiger reserve, elephant reserve, and Important Bird Area.
• Nameri is contiguous with the Pakke Tiger Reserve in Arunachal Pradesh, together forming one of the largest blocks of semi-evergreen and evergreen forest in Northeast India.
• One of four tiger reserves in Assam — the others being Kaziranga, Manas, and Orang; Kaziranga and Manas are also UNESCO World Heritage Sites.
• Known for diverse avifauna including the White-winged Wood Duck, and a rare assemblage of sympatric carnivores — Royal Bengal Tiger, Leopard, Clouded Leopard, and Wild Dogs.

Tiger Reserve Governance in India

• Tiger reserves are established under Project Tiger (launched 1973) and are managed under the oversight of the National Tiger Conservation Authority (NTCA), established in 2005 under the Wildlife (Protection) Act, 1972.
• Each tiger reserve has a protected core (critical tiger habitat), free from human activity, and a buffer zone permitting regulated human use.
• India’s tiger population and tiger reserve status is periodically assessed through the All India Tiger Estimation (AITE), conducted by the NTCA and WII once every four years.

Comparison — Kaziranga Tiger Reserve

• Kaziranga, better known for its one-horned rhinos, has one of the highest tiger densities in India — 13.44 per 100 sq. km.
• The 2022 AITE recorded 104 tigers in Kaziranga; a 2024 Assam Forest Department report, ‘Status of Tigers in Kaziranga Tiger Reserve’, put the figure at 148 tigers.

Nameri’s recovery from three to twelve tigers in three years, alongside the return of tigers to Sonai-Rupai after decades of local extinction, illustrates how sustained habitat protection and scientific monitoring can revive a small, satellite-linked tiger population. Sustaining this trend will require continued protection of the Nameri-Pakke transboundary forest corridor with Arunachal Pradesh.

Prelims Pointers

• Nameri Tiger Reserve = located in Sonitpur district, Assam; contiguous with Pakke Tiger Reserve, Arunachal Pradesh.
• Assam’s four tiger reserves = Kaziranga, Manas, Nameri, Orang (Kaziranga and Manas are also UNESCO World Heritage Sites).
• Sonai-Rupai Wildlife Sanctuary = satellite core of Nameri Tiger Reserve; tigers returned here after being locally extinct since the early 2000s.
• NTCA = National Tiger Conservation Authority, established 2005 under the Wildlife (Protection) Act, 1972, to oversee India’s tiger reserves.
• WII = Wildlife Institute of India; validates tiger population estimates alongside the NTCA.
• Kaziranga = highest tiger density among Indian reserves (13.44/100 sq. km per 2022 AITE); also famous for one-horned rhinos.

Practice Mains Question

Examine the role of satellite core areas and transboundary forest corridors in sustaining small tiger populations, with reference to the recent recovery of tiger numbers in Assam’s Nameri Tiger Reserve.

Radio Telemetry and the Case of a Straying White-Rumped Vulture

GS Paper 3 — Environment & Biodiversity | Conservation Technology

Why in News

A radio-tagged white-rumped vulture, identified as ‘Z25’, was found electrocuted on a power transmission line in the Nilgiris, near Mudumalai Tiger Reserve, after data from its radio transmitter had already flagged unusual behaviour suggesting it was not adapting well to the wild. The case illustrates both the value and the limits of radio telemetry as a tool for monitoring and protecting critically endangered vulture populations.

Background of the Case

• Z25 was one of five captive-bred white-rumped vultures radio-tagged at Tadoba on 22 December 2025 and released at the Tadoba-Andhari Tiger Reserve on 30 December 2025, as part of monitoring by the Bombay Natural History Society (BNHS).
• Within one to two weeks, Z25 flew out of Tadoba-Andhari and travelled south to Kalaburagi, Karnataka, where it was captured by the Karnataka Forest Department and held at the Kalaburagi Zoological Park.
• It was later relocated to the Mudumalai Tiger Reserve, Tamil Nadu, where an existing white-rumped vulture population offered a better chance of acclimatisation — but radio telemetry data continued to show the bird straying from the reserve, exhibiting a pattern of seeking out human presence, likely learned from earlier exposure to human feeders.
• The BNHS team, based on this telemetry data, was considering relocating Z25 to a breeding centre when the bird was electrocuted on a power transmission line, before that plan could be implemented.
• Z25 had originally been captive-bred at the Jatayu Conservation Breeding Centre, Pinjore, run by the Haryana Forest Department.

Significance of Radio Telemetry

• Radio telemetry involves fitting an animal with a radio transmitter to track its movements remotely and in real time — a critical tool for studying critically endangered species and guiding conservation interventions.
• It allows conservationists to detect behavioural anomalies (such as a released bird straying from its intended habitat) early, enabling timely intervention before an animal is lost to threats such as electrocution, poisoning, or starvation.
• Power transmission line electrocution and collision remain a major threat to large birds, including vultures, across India, alongside the historical driver of vulture population collapse — poisoning from the veterinary drug diclofenac.

Prelims Pointers

• Radio telemetry = tracking an animal’s movements remotely via a fitted radio transmitter; used to study and protect endangered species.
• White-rumped vulture = a critically endangered vulture species (IUCN Red List) native to South Asia; population collapsed historically due to diclofenac poisoning.
• Jatayu Conservation Breeding Centre, Pinjore (Haryana) = a key captive-breeding facility for vultures in India.
• BNHS = Bombay Natural History Society, a leading NGO involved in vulture conservation and monitoring in India.
• Power transmission line electrocution is a significant, human-infrastructure-linked threat to large bird species in India.

Article 07

The Problem With Irrational Fixed-Dose Combination (FDC) Drugs

GS Paper 2 — Health Policy & Regulation | GS Paper 3 — Science & Technology

This article is based on an “Expert Explains” interview format (Dr Kamini Walia, ICMR, in conversation with a journalist) rather than a straight news report. Views on specific drug combinations reflect the expert’s professional assessment; the factual details of the ban itself have been independently verified against the government notification.

Why in News

The Ministry of Health and Family Welfare has prohibited the manufacture, sale, and distribution of 16 fixed-dose combination (FDC) drugs with immediate effect, under a Gazette Notification dated 11 June 2026, invoking Section 26A of the Drugs and Cosmetics Act, 1940. The banned list includes certain antibiotic combinations and a range of dermatological products containing aloe vera and other herbal ingredients, following a multi-year review by the Drug Technical Advisory Board (DTAB) and its expert sub-committee.

What Is an ‘Irrational’ FDC?

• A Fixed-Dose Combination (FDC) contains two or more active pharmaceutical ingredients in a single formulation, commonly prescribed for infections, pain, and skin ailments.
• An FDC is “irrational” when there is no scientifically established rationale for combining the ingredients, or when clinical evidence does not show the combination is more beneficial than using the individual medicines separately. A rational FDC requires each component to contribute meaningfully, have compatible pharmacological properties, and demonstrate additional clinical benefit over separate use.
• Per Dr Kamini Walia, Senior Scientist, Indian Council of Medical Research (ICMR), irrational combinations expose patients to unnecessary drugs, raise costs, and — in the case of antibiotics — contribute to antimicrobial resistance (AMR).

The Full List of 16 Banned FDCs

No.	Combination
1	Acetyl Salicylic Acid + Ethoheptazine
2	Aloe Vera + Jojoba Oil + Wheat Germ Oil + Tea Tree Oil
3	Amoxicillin + Serratiopeptidase + Lactobacillus Sporogenes
4	Dicyclomine + Paracetamol + Clidinium Bromide + Chlordiazepoxide
5	Amoxicillin + Serratiopeptidase
6	Aloe Extract + Allantoin + Alpha Tocopherol Acetate + D-Panthenol + Vitamin A
7	Aloe Extract + Vitamin E + Dimethicone + Glycerine
8	Aloe Vera + Jojoba Oil + Vitamin E
9	Aloe Vera + Orange Oil
10	Aloe Vera + Vitamin E + Herbal Preparation
11	Aloe Vera + Tea Tree Oil
12	Dicyclomine + Paracetamol + Clidinium Bromide
13	Paracetamol + Lignocaine
14	Gliclazide + Chromium Picolinate
15	Cefadroxyl + Probenecid
16	Cefuroxime + Serratiopeptidase

Case Studies of Irrational Combinations

Amoxicillin + Serratiopeptidase

Serratiopeptidase is a proteolytic enzyme with very limited supporting evidence when combined with antibiotics. It is acid-labile — likely to degrade in the stomach before reaching the bloodstream — and no peer-reviewed randomised controlled trial has shown that it improves bacterial clearance, raises cure rates, or reduces the antibiotic dose required. No major treatment guideline recommends it as an antibiotic adjunct.

Norflox TZ (Norfloxacin + Tinidazole)

Norfloxacin treats bacterial infections while tinidazole targets protozoal infections; patients rarely suffer both simultaneously, so one component is typically redundant while still contributing to unnecessary bacterial resistance pressure.

Augmentin 625 (Amoxicillin + Clavulanic Acid)

Clavulanic acid blocks enzymes that resistant bacteria use to destroy amoxicillin — a rational combination only when the infecting bacteria are actually resistant; otherwise the clavulanic acid offers no benefit.

Steroid + Antifungal Combination Creams

These provide temporary relief from itching and redness, but the steroid component suppresses the skin’s local immune response, which can allow an underlying fungal infection to worsen, spread, or develop resistance.

How FDCs Are Regulated Globally

Jurisdiction	Regulatory Approach
United States	Every FDC requires a new drug application with clinical evidence of superiority or added convenience over its individual components.
WHO	Explicitly cautions against irrational FDCs; only evidence-based combinations feature on the WHO Essential Medicines List.
India (pre-reform)	Thousands of FDCs were approved by state licensing authorities without central review, exploiting a loophole in the Drugs and Cosmetics Act.
India (post-2016)	Around 6,000 FDCs reviewed by an expert committee; bans initiated in phases, including the present 16-FDC action under Section 26A.
European Union	Full scientific review of FDCs; approval requires supporting clinical data.

Risks and Way Forward

• Irrational FDCs expose patients to unnecessary drugs, adverse effects, drug interactions, and allergic reactions, and make it harder for doctors to titrate the dose of one ingredient without over- or under-dosing another.
• Unjustified antibiotic FDCs encourage unnecessary or prolonged antibiotic exposure, creating selective pressure that allows antimicrobial-resistant organisms to survive and multiply — a public health concern independent of any single patient’s outcome.
• Longevity of a product in the market does not establish its scientific validity — several long-sold aloe vera-based dermatological FDCs were banned for lacking demonstrable added clinical benefit over their individual ingredients.
• Way forward: doctors should de-escalate patients from banned FDCs to rational, evidence-based therapies; pharmacists should track the regulator’s banned-FDC list; patients should understand that a multi-ingredient medicine is not inherently more effective than a targeted, evidence-backed one.

The ban on 16 FDCs reflects a maturing, evidence-driven approach to drug regulation in India, moving away from a historically permissive state-level approval system. The larger challenge remains completing the review of the roughly 6,000 FDCs still in the regulatory pipeline, and ensuring prescribers and pharmacists across India’s vast retail pharmacy network act on these findings promptly, particularly where antimicrobial resistance is concerned.

Prelims Pointers

• FDC = Fixed-Dose Combination; a formulation with two or more active pharmaceutical ingredients in one dosage form.
• Section 26A, Drugs and Cosmetics Act, 1940 = empowers the Central Government to prohibit manufacture, sale, or distribution of a drug in the public interest — the legal basis for this ban.
• DTAB = Drug Technical Advisory Board, the apex technical body advising the government on drug regulation, including FDC reviews.
• Antimicrobial Resistance (AMR) = when microorganisms evolve to resist medicines designed to kill them; irrational antibiotic FDCs are a recognised driver of AMR.
• Around 6,000 FDCs have been reviewed by India’s expert committee process since 2016; the present action bans 16 of them.
• The WHO Essential Medicines List includes only evidence-based FDCs, unlike India’s historically permissive pre-2016 approval regime.

Prelims Practice MCQ

With reference to Fixed-Dose Combination (FDC) drugs in India, consider the following statements:
1. The recent ban on 16 FDCs was notified under Section 26A of the Drugs and Cosmetics Act, 1940.
2. A rational FDC requires each of its components to demonstrate additional clinical benefit compared to using the medicines separately.
3. The World Health Organization’s Essential Medicines List includes FDCs regardless of the strength of their supporting clinical evidence.

Which of the statements given above is/are correct?

• (a)1 and 2 only
• (b)2 and 3 only
• (c)1 and 3 only
• (d)1, 2 and 3

Correct Answer: (a)

Statement 1 is correct — the ban invokes Section 26A of the Drugs and Cosmetics Act, 1940. Statement 2 is correct — demonstrable additional clinical benefit over separate use is one of the defining criteria of a rational FDC. Statement 3 is incorrect — the WHO explicitly cautions against irrational FDCs, and only evidence-based combinations feature on its Essential Medicines List.
