RT Journal Article SR Electronic 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 FD Parenteral Drug Association (PDA) SP 194 OP 203 VO 61 IS 3 A1 Prasun Das YR 2007 UL http://journal.pda.org/content/61/3/194.abstract AB 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.
