The Education Pipeline: Training India's Pharmaceutical Scientists
While India's pharmaceutical industry and research laboratories have achieved global recognition, the education system that trains future scientists faces both challenges and opportunities. Pharmacy education in India began at Banaras Hindu University in 1932 under Professor M.L. Schroff, but after nearly a century of development, questions remain about how well it keeps pace with global standards 3 .
Current Challenges
- Entry of unqualified students
- Outdated curriculum
- Lack of industrial and clinical exposure
- Limited research-oriented learning
Modernization Efforts
- Industrial and clinical exposure
- Research-oriented learning
- Updated curricula with contemporary topics
- Application of Total Quality Management principles
Several flaws have been identified in the current system, including the entry of unqualified students, outdated curriculum, and lack of industrial and clinical exposure 3 . The Education Regulation of the Pharmacy Council of India (PCI) governing diploma education hadn't undergone significant updates in over 20 years at the time of a 2011 analysis, with students still receiving older compounding practical exposure rather than contemporary training 3 . This has resulted in graduates who sometimes lack the professionalism and rational thinking needed in modern pharmaceutical careers.
However, promising changes are emerging. There's growing emphasis on providing students with industrial and clinical exposure, incorporating research-oriented learning, and updating curricula to include contemporary topics like high-throughput screening and biologics 1 3 . The application of Total Quality Management (TQM) principles to educational systems is also being explored to improve the current situation 3 .
Recent government initiatives aim to strengthen this educational foundation. The PRIP scheme (Promotion of Research and Innovation in Pharma MedTech sector) launched by the Department of Pharmaceuticals with a financial outlay of ₹5,000 crores (approximately $600 million) specifically aims to transform India into a global powerhouse for pharmaceutical R&D 6 . The scheme includes funding for industry-academia collaborations, supporting the transition of research from lab to market, and encouraging emerging innovators from MSMEs and startups 6 .
Inside the Lab: High-Throughput Screening - The Search Needle in the Chemical Haystack
One of the most critical technologies modern pharmaceutical researchers use is High-Throughput Screening (HTS), a method that allows scientists to quickly conduct millions of chemical, genetic, or pharmacological tests to identify potential drug candidates 9 . Think of it as an extremely efficient way to find a needle in a haystack—if the needle could potentially cure diseases and the haystack contained millions of chemical compounds.
What is High-Throughput Screening?
HTS integrates robotics, data processing software, liquid handling devices, and sensitive detectors to rapidly test thousands to millions of compounds for biological activity against a specific target, such as a protein implicated in disease 4 . The term "high-throughput" refers to the ability to test 10,000–100,000 compounds per day, with systems capable of testing beyond 100,000 compounds considered "ultra-high-throughput screening" 4 .
The process typically uses microtiter plates—small plastic plates with a grid of small wells—as testing vessels 9 . These plates can have 96, 384, 1536, or even 6144 wells, allowing researchers to test multiple compounds simultaneously 9 . Each well contains a different chemical compound, plus the biological target that researchers want to affect (such as cells, proteins, or enzymes).
The HTS Process: A Step-by-Step Journey
The journey of drug discovery through HTS follows a structured path:
Assay Development
Scientists design a test that can measure whether a compound affects their target.
Compound Library Preparation
Collections of chemical compounds are prepared in source plates.
Automated Screening
Robotics transfer compounds to assay plates containing the biological target.
Hit Identification & Validation
Compounds showing desired activity are identified and validated.
| Screening Aspect | Traditional Methods | Modern HTS | Recent Advances |
|---|---|---|---|
| Compounds Tested Per Day | Hundreds | 10,000-100,000 | Up to 100 million (using drop-based microfluidics) |
| Well Plate Formats | Test tubes, small plates | 96-384 wells | 1536, 3456, or 6144 wells |
| Liquid Volumes | Milliliters | Microliters | Nanoliters (10^-7 times reagent volume) |
| Cost per Test | High | Moderate | 1-millionth of conventional techniques |
Recent advances have made HTS even more powerful. Quantitative HTS (qHTS) now allows researchers to generate full concentration-response relationships for each compound, providing more sophisticated data for decision-making 9 . Meanwhile, drop-based microfluidics has enabled screens of 100 million reactions in just 10 hours at one-millionth the cost of conventional techniques 9 .
Case Study: Discovering a New Diabetes Drug Through HTS
To understand how HTS works in practice, let's explore a hypothetical but realistic scenario where CSIR researchers use this technology to identify a potential new treatment for type 2 diabetes.
The Setup: Defining the Drug Target
Our story begins with basic research that has identified a specific protein (let's call it "GPTR-12") involved in regulating blood sugar levels. Scientists have determined that activating this protein could help cells respond better to insulin, making it a promising drug target for type 2 diabetes. The CSIR team's goal is to find a compound that safely activates GPTR-12.
The Methodology: A Step-by-Step Hunt
The researchers follow a meticulous process:
- Assay Design: The team develops a test that produces fluorescence when GPTR-12 is activated.
- Compound Selection: The team selects a diverse library of 200,000 chemical compounds.
- Automated Screening: A robotic system transfers compounds and measures fluorescence.
- Quality Control: The team includes control wells to validate the assay.
The Results: Finding the Needles in the Haystack
Initial Screening
After the initial screen, data analysis reveals 1,200 compounds showed significant activity (approximately 0.6% hit rate).
Hit Validation
After eliminating false positives and problematic compounds, 200 promising "hits" remain.
Dose-Response Testing
These 200 compounds undergo dose-response testing to determine their potency.
Lead Identification
The team identifies Compound 78a as their most promising candidate, with high potency and good selectivity for GPTR-12 over related proteins.
While Compound 78a is far from becoming an approved medicine, its discovery represents a crucial first step in what could become a 10-15 year drug development journey. The identification of this compound through HTS demonstrates how automated technologies can rapidly accelerate the early stages of drug discovery, potentially bringing new treatments to patients faster.

The Future of Indian Pharma Research: Challenges and Opportunities
Despite its impressive growth, India's pharmaceutical research ecosystem faces significant challenges. A detailed analysis of health research funding revealed that total available funding represented just 0.09% of India's GDP in 2011-12, with only 0.02% coming from public sources . Additionally, only 3.2% of total health research funding was allocated to public health research, creating a mismatch between research priorities and the country's major health challenges .
However, the future looks promising with several government initiatives aiming to strengthen the research landscape:
PRIP Scheme
₹5,000 crore (approximately $600 million) outlay to transform India into a global R&D powerhouse 6 .
FDI Policy
Up to 100% FDI allowed through automatic route for Greenfield pharmaceutical projects 8 .
These initiatives are already showing results. The Indian pharmaceutical industry saw steady growth with a compound annual growth rate (CAGR) of 6-8% between FY 2018 and FY 2023, while foreign direct investment in the sector crossed the $20 billion mark in September 2022 1 .
