I apologize for any confusion caused. As an AI language model, my responses are based on data available up until September 2021, and I do not have access to real-time event information or schedules beyond that point. To obtain accurate and up-to-date information about the PDA Data Integrity Workshop in 2023, including dates, location, agenda, speakers, and registration details, I recommend visiting the official website of the Parenteral Drug Association (PDA) or contacting the organization directly. They will be able to provide you with the most reliable and current information about their workshop offerings in 2023.
