Indigenous Drug Discovery in India: Opportunities for New Chemical Entities and Global Innovation
Abstract
India has emerged as one of the world’s leading producers of generic medicines; however, the country’s contribution to innovative drug discovery and development of New Chemical Entities (NCEs) has historically remained limited compared with major pharmaceutical innovation hubs. Over the past two decades, significant efforts have been made to strengthen India’s drug discovery ecosystem through investment in research infrastructure, expansion of pharmaceutical R&D programs, and increasing collaboration between academia and industry. The introduction of product patent protection in 2005 and the growth of biotechnology and computational drug discovery platforms have further stimulated indigenous innovation in the pharmaceutical sector. Despite these developments, challenges such as high research costs, long development timelines, regulatory complexity, and limited venture capital investment continue to constrain the growth of NCE discovery in India. This review analyzes the current landscape of indigenous drug discovery in India, highlighting the evolution of pharmaceutical R&D capabilities, opportunities for innovation in NCE development, and strategies for strengthening India’s global role in pharmaceutical innovation. The paper also explores emerging research trends including open-source drug discovery, artificial intelligence–assisted drug design, and the integration of traditional medicinal knowledge with modern pharmaceutical science. Strengthening indigenous drug discovery capabilities will be essential for transforming India from a generics powerhouse into a globally recognized innovation-driven pharmaceutical economy.

1. Introduction
Drug discovery represents one of the most complex and resource-intensive processes in modern biomedical research. The development of a new therapeutic molecule typically requires more than a decade of research and billions of dollars in investment before reaching the market. Historically, pharmaceutical innovation has been concentrated in developed countries such as the United States, Germany, Japan, and the United Kingdom.
India’s pharmaceutical industry has traditionally focused on the production of generic medicines, particularly after the introduction of the Indian Patents Act of 1970, which permitted process patents but not product patents for pharmaceuticals. This legal framework enabled Indian pharmaceutical companies to manufacture affordable versions of patented drugs using alternative synthesis methods.
However, India’s participation in innovative drug discovery remained limited until the late twentieth century. Prior to the mid-1990s, India’s presence in NCE discovery and global pharmaceutical innovation was relatively small. (American Chemical Society Publications)
The implementation of product patents in 2005 under the Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement significantly altered the pharmaceutical innovation landscape. This policy change encouraged Indian pharmaceutical companies to invest more heavily in research and development aimed at discovering novel therapeutic molecules.
Today, India is gradually building a robust ecosystem for indigenous drug discovery, supported by pharmaceutical companies, academic institutions, biotechnology startups, and government research organizations.
2. Evolution of Drug Discovery Research in India
The evolution of drug discovery in India can be broadly divided into three phases.
2.1 Pre-1990 Era: Process Innovation and Generics
Before economic liberalization in the 1990s, Indian pharmaceutical companies focused primarily on reverse engineering of patented drugs. The absence of product patents enabled firms to produce generic medicines using alternative manufacturing processes.
This strategy allowed India to become a global leader in affordable generic medicines but did not encourage significant investment in novel drug discovery.
2.2 Post-Liberalization Era: Emergence of R&D Programs
Following economic reforms and globalization in the 1990s, several major Indian pharmaceutical companies began establishing in-house research programs dedicated to drug discovery.
Companies such as Ranbaxy, Dr. Reddy’s Laboratories, Glenmark, and Zydus initiated programs to discover new therapeutic molecules targeting diseases such as diabetes, cancer, and infectious diseases. (Pharma Focus Asia)
These programs marked the first major attempt by Indian firms to enter the global pharmaceutical innovation landscape.
2.3 Post-2005 Era: Innovation under the Product Patent Regime
The introduction of product patents in India in 2005 significantly strengthened incentives for pharmaceutical innovation.
Indian pharmaceutical firms began investing more heavily in NCE research programs, while biotechnology startups and contract research organizations expanded their role in drug discovery and development.
Today, India’s drug discovery ecosystem includes pharmaceutical companies, academic research institutes, biotechnology startups, and contract research organizations that collectively contribute to global pharmaceutical innovation.
3. Notable Achievements in Indigenous Drug Discovery
Although India’s contribution to global NCE discovery remains modest compared with leading pharmaceutical nations, several important milestones have been achieved.
One of the most notable examples is Saroglitazar, an antidiabetic drug discovered and developed by an Indian pharmaceutical company. It represents one of the first indigenously developed NCEs to reach the market in India.
Another major achievement is Enmetazobactam, a novel β-lactamase inhibitor antibiotic developed by an Indian pharmaceutical research team and later approved by regulatory authorities in multiple countries. (Wikipedia)
These examples demonstrate that Indian pharmaceutical researchers possess the scientific capabilities required to contribute to global pharmaceutical innovation.
4. Role of Contract Research Organizations in Drug Discovery
Contract research organizations (CROs) have emerged as critical players in India’s drug discovery ecosystem. These organizations provide specialized research services to global pharmaceutical companies, including:
- target identification
- lead optimization
- preclinical testing
- clinical trial management
The growth of CROs in India has been driven by the availability of highly skilled scientists, advanced research infrastructure, and relatively lower operational costs.
Many CROs now provide end-to-end drug discovery services, supporting global pharmaceutical companies throughout the drug development process. (Syngene International Ltd)
