What is a GMP Certified Manufacturer?

Imagine this scenario: you work for a pharmaceutical company and have just purchased a product and need to find a manufacturer to make this product for you. Your boss has just told you to find a GMP certified manufacturer. Sounds easy enough, but what exactly is a GMP certified manufacturer and why do you need one?

The acronym stands for Good Manufacturing Practices, and to be GMP certified means that the manufacturer has demonstrated a strong regulatory commitment and compliance to international GMP standards.
