TY - JOUR T1 - Development of a Process Control Scheme for Reduction in Weight Variation of Capsules JF - PDA Journal of Pharmaceutical Science and Technology JO - PDA J Pharm Sci Technol SP - 194 LP - 203 VL - 61 IS - 3 AU - Prasun Das Y1 - 2007/05/01 UR - http://journal.pda.org/content/61/3/194.abstract N2 - This study aims to investigate the causes of different sources of weight variation of capsules and thereby to suggest a suitable control scheme to improve productivity in a pharmaceutical industry. Data are analysed, using the capsule filling process, under a mixed effect cross-nested model. The process capabilities are estimated using Clements’ method followed by developing a routine setting and control procedure. ER -
