Both flow rate and percent compressibilityPublication Open Access Comparative evaluation of hydroxypropyl cellulose and povidone in paracetamol tablet formulation(1993) Nuttanan Sinchaipanid; Ampol Mitrevej; ณัฐนันท์ สินชัยพานิช; อำพล ไมตรีเวชformulations. HPC-M and PVP-K90 were incorporated at 0.6% and l.0% dry basis. ln addition to paracetamol, binder and either corn starch, tapioca starch or pregelatinized starches were added. The granulations were lubricated with magnesium stearate. lt was found... that, regardless of tre binder, corn starch and tapioca starch did not give acceptable tablets. Pregelatinized starches appeared to give better tablsts. At 0.6% level, HPC-M produced softer and slower disintegration tablets than did PVP-K90, while tre dissolutronPublication Open Access Application of stress relaxation to herbal tablet formulation(1997) Ampol Mitrevej; Orawan Chitvanich; Nuttanan Sinchaipanid; Monechoulie Nitibhon; อำพล ไมตรีเวช; อรวรรณ จิตรวานิช; ณัฐนันท์ สินชัยพานิช; มนต์ชุลี นิติพน; Mahidol University.

The stress relaxation curves were analyzed using Shott, Maxwellian, and Hiestand treatments The three methods gave similar results. Herbal powders with high... cellulose content were found to undergo more plastic deformation than did those with high starch content. The degree of deformation depended upon the peak compressron forces. The tableting behavior of the direct compression fillers was altered upon
