Risk Assessment for Different Formulations in a Highly Potent Drug Facility: Oral Solid Dose & Liquid Dosage Formulations
Handling of highly potent active pharmaceutical ingredients (HPAPIs) within a shared multi-product GMP facility requires proactive risk assessment for both quality and occupational reasons: preventing cross-contamination means safer medicines for patients, while preventing unacceptable exposure means a safer environment for workers. Thorough risk assessment requires careful consideration of numerous factors including health-based exposure limits, the formulation and associated physical properties, the manufacturing process, batch size, and the available facility and product handling engineering controls. Personal protective equipment must always be a last resort. In this article, some important considerations are presented when assessing risks for different formulations in a highly potent drug facility for oral solid dose and liquid dosage formulations, including contrasting cross-contamination risk assessment vs occupational risk assessment.
