Good Manufacturing Practice (GMP) Compliance in Hong Kong

Good Manufacturing Practice (GMP) is a critical quality assurance system that ensures pharmaceutical products are consistently produced and controlled according to quality standards. In Hong Kong, GMP compliance is mandatory for all pharmaceutical manufacturers.

Understanding GMP Requirements

GMP encompasses all aspects of production from raw materials, premises, and equipment to training and personal hygiene of staff. The primary objective is to prevent contamination, mix-ups, and errors during manufacturing.

Key GMP Principles:

• Quality management systems
• Personnel qualifications and training
• Premises and equipment standards
• Documentation and record keeping
• Production controls
• Quality control testing
• Storage and distribution

Hong Kong GMP Framework

The Drug Office of the Department of Health oversees GMP compliance under the Pharmacy and Poisons Ordinance. All manufacturing facilities must obtain a Manufacturer's License and undergo regular inspections.

Regulatory Requirements:
