Frequently Asked Questions
What is an API?
API is an abbreviation for Active Pharmaceutical Ingredient, the main ingredient in a medicine that causes the desired effect of the medicine. Some medicines contain more than one API that act in different ways in the body. APIs may also be referred to as drug substances or pharmacologic substances.
What is CGMP compliance?
CGMP stands for Current Good Manufacturing Practice, a set of regulations that ensures the safety, quality, and consistency of pharmaceuticals. CGMP guidelines include qualification, validation, and documentation.
Why is CGMP compliance important?
CGMP compliance ensures the safety, quality, and consistency of pharmaceuticals. It is critical for meeting regulatory requirements for pharmaceuticals. They guarantee the identity, strength, and purity of drugs, protecting consumer health and ensuring product efficacy.
What are CEPs and DMFs?
CEP stands for ‘Certification of suitability to the monographs of the European Pharmacopoeia’. DMF stands for Drug Master File. A DMF is a submission to the US Food and Drug Administration (FDA) that may be used to provide confidential detailed information about facilities, processes, or articles used in the manufacturing, processing, packaging, and storing of one or more human drugs.

What carriers are used to transport finished CGMP/API products?
Cayman utilizes prequalified global transportation service providers that meet stringent standards for the safe and secure delivery of our finished CGMP/API products. While we have relationships with preferred carriers, other transportation organizations can be contacted, upon request, to meet specific logistical needs or preferences by our clients.
Can Cayman manufacture my custom product under CGMP standards?
