Automation Challenges in Indian Pharma

India is a global leader in pharmaceutical manufacturing, supplying medicines to regulated markets such as the US and Europe. Major pharma hubs like Pune, Hyderabad, Ahmedabad, Mumbai, and Baddi host large-scale manufacturing facilities. However, automation challenges in Indian pharma are growing as USFDA and WHO-GMP compliance requirements become more stringent.

Modern audits focus heavily on data integrity, validation, traceability, and system security. While industrial automation is essential to address these challenges, success depends on proper planning, compliant system design, and robust implementation.

Data Integrity: A Major Compliance Risk

Poor data integrity remains one of the most common reasons for USFDA warning letters in Indian pharmaceutical plants.

Many facilities still rely on:

• • Manual logbooks

• • Excel-based records

• • PLC systems without audit trails

These methods increase the risk of missing, editable, or non-traceable data.

Properly designed modern PLC and SCADA automation solutions help meet ALCOA+ principles by ensuring data remains secure, traceable, and tamper-proof. Pharmaceutical companies in Pune and across India are upgrading to SCADA systems with audit trails, user access control, and secure data logging to maintain audit readiness.

Validation & Documentation Challenges

In pharmaceuticals, automation extends beyond running machines—it must be validated.

Common Automation challenges in Indian pharma include:

• • Automation Challenges in Indian Pharma often arise from incomplete URS, FDS, or SDS documentation, undocumented PLC logic changes, and the absence of proper version control or change history. Even minor, unrecorded modifications in automation logic can trigger serious audit observations or batch rejection. To overcome these automation challenges in Indian pharma, manufacturers must strictly follow GAMP 5 guidelines and maintain robust validation, change control, and documentation practices to meet USFDA and WHO-GMP compliance requirements..

Integrating Legacy Machines in Existing Plants

Many Indian pharmaceutical manufacturing units operate brownfield plants mixing old and new equipment.

Challenges include:

• •  Standalone PLCs

• •  Manual operations

• •  Lack of centralized monitoring

Integrating these systems into a unified factory automation or SCADA platform proves difficult but necessary. Plants in MIDC Pune, Chakan, Pimpri-Chinchwad, and Maharashtra industrial zones increasingly choose automation retrofitting over complete replacement to reduce costs and downtime.

Batch Control & Traceability Issues

Batch traceability represents a key requirement under WHO-GMP and USFDA regulations.

Manual batch records and operator-dependent processes often result in:

• •  Missing data

• •  Inconsistent records

• •  Delayed audit responses

Automation systems featuring recipe management, batch control, and electronic batch records (EBR) ensure consistency, accuracy, and faster audit readiness.

Cleanroom & Environmental Monitoring

Environmental conditions like temperature, humidity, and pressure must remain within specified limits during pharmaceutical production.

Common problems include:

• •  Manual readings taken once or twice per shift

• •  Delayed alarms

• •  Absence of historical trend data

Automated Environmental Monitoring Systems (EMS) integrated with SCADA provide real-time alerts, continuous data logging, and streamlined audit reports—now widely adopted by pharmaceutical plants across Pune and India.

Human Dependency & Operator Errors

Despite automation, many pharmaceutical processes remain heavily dependent on operators.

Typical issues include:

• •  Incorrect parameter entry

• •  Missed SOP steps

• •  Inconsistent operation

Automation featuring guided HMI screens, interlocks, and alarm management reduces human error and ensures processes follow compliance standards precisely.

Cybersecurity & Access Control

Regulators now closely examine automation system security.

Common audit findings include:

• • Shared passwords

• • Unrestricted PLC access

• • Unsecured SCADA networks

To address automation challenges in Indian pharma, modern industrial automation systems prioritize secure user authentication, detailed access logs, reliable data backups, and robust network security—all of which are critical for meeting USFDA compliance requirements.

Skill Gap & Automation Support

Many Indian pharmaceutical companies depend entirely on vendors for automation changes.

This creates issues such as:

• •  Audit delays

• •  Dependency for minor modifications

• •  Limited system understanding

Partnering with an experienced automation system integrator in Pune or India ensures long-term support, standardized systems, and improved audit preparedness.
