Equipment Selection for Capsules MCQs With Answer

Introduction

Selecting the right equipment for capsule manufacturing is critical during scale-up and technology transfer. This set of MCQs focuses on practical and regulatory considerations M.Pharm students must master: machine types (tamping, dosator, piston), capsule sizes and materials, throughput and fill-weight accuracy, powder flow and granule characteristics, containment for potent APIs, cleaning and validation requirements, and material compatibility. Questions emphasize decision-making during scale-up — matching process capability to clinical and commercial demands, ensuring product quality, and minimizing cross-contamination and downtime. Use these questions to test and deepen your understanding of technical criteria that drive equipment choices for capsule production at different scales.
