Workshop on Medicines Regulation in the Caribbean Barbados, September 8-9, 2009 Essential Regulatory Functions: Quality Assurance The CRDTL Experience Lucette Cargill Caribbean Regional Drug Testing Laboratory

Essential Regulatory Functions Licensing of premises, practices and persons Inspection of manufacturers and distributors Product assessment and registration Monitoring quality of drugs Control of drug promotion and advertising Adverse drug reaction monitoring

Monitoring Drug Quality When  Pre-registration  Post-marketing Why  Verify quality attributes before registration  Verify quality of procured products  Verify quality of products in circulation  Investigate complaints or other problems

Establishment of the CRDTL The Caribbean Regional Drug Testing Laboratory was established to provide the region with a well-equipped quality control laboratory to evaluate the quality of pharmaceuticals used in the region. This would enable the selection of drugs of good quality for use by identifying those of reliable quality. Work commenced in 1980.

Testing Activities The laboratory has operated a routine surveillance programme built largely around a priority list of drugs selected by the Technical Advisory Committee. Submissions for pre-registration or pre- tender analysis, routine surveillance, quality problems or other regulatory actions etc. also received

Users of Services The main users of the laboratory are Drug Regulatory Authorities, and the OECS- PPS. Other users include pharmaceutical manufacturers, distributors and occasionally, hospitals.

Challenges Unavailability of product monographs  Usual sources are United States, British and International Pharmacopoeia  Monographs not included for some products  Drug Regulatory Agency should provide manufacturer’s monograph submitted with application for registration  Some countries do not have registration systems in place

Challenges Unavailability of reference Standards  Normally purchased from USP, BP, WHO Collaborating Centre  Some standards not available from these sources  Reference substances generally supplied to regulatory agency with registration application  Some countries do not have registration systems in place

Challenges Scheduling issues  No control over timing of submissions  No prior knowledge of planned activities of user agencies Equipment issues  Unavailability of infrequently used item Resources

Possible Solutions Collaboration with national laboratories  Laboratory network?  Other mechanisms? Cooperation of regulatory agencies  Harmonized registration requirements  Regional approach  Provision of reference standards  Agreement on specifications for pharmaceutical preparations
