Automation and digitalization in drug product process development.

The pharmaceutical industry is undergoing a significant digital transformation, with automation emerging as a central strategy to streamline drug product (DP) process development, reduce costs, and enhance operational efficiency. This paper explores current trends and practical implementations of automation across key areas, including data management, automated documentation and report generation, digitalization of unit operations, regulatory query (RTQ) handling, and preparation of regulatory submissions. Special emphasis is placed on the emerging role of large language model (LLM)-based chatbots, which are increasingly being used to support knowledge management, streamline RTQ responses, and automate routine tasks. We provide an in-depth review of both mature technologies and innovative tools currently being piloted or adopted across the industry. The potential benefits of these solutions-including improved data integrity, shortened development timelines, and increased regulatory compliance-are discussed in the context of real-world applications. Each automation domain is illustrated with examples. Importantly, we also address how these technologies can be deployed within Good Documentation Practices (GDP) frameworks, ensuring quality, traceability, and compliance in regulated environments.
