This is where 21 CFR Part 11 compliance becomes essential.

It defines how pharmaceutical companies must manage:

• Electronic records
• Electronic signatures
• System security

 In simple terms:
If you use digital systems in pharma, you must comply with 21 CFR Part 11.

What is 21 CFR Part 11?

21 CFR Part 11 is a regulation issued by the U.S. Food and Drug Administration (FDA) that governs the use of electronic records and electronic signatures in regulated industries like pharmaceuticals, biotechnology, and medical devices.

It ensures that:

• Electronic records are trustworthy
• Digital signatures are legally valid
• Data cannot be altered without trace

 This regulation applies to all systems used in:

• Manufacturing
• Quality management
• Laboratory operations

What Does 21 CFR Part 11 Compliance Mean?

21 CFR Part 11 compliance means your software and processes must ensure:
