The lubricant susceptibility of two direct compression excipients, Avicel P
H-200 and Cellactose, was determined using a model mix with metamizol sodiu
m (dipyrone) and designed experiments to obtain a quantitative relationship
by multiple regression. As a result, a new constant called specific lubric
ant sensibility L-s is proposed for the comparison of lubricant susceptibil
ity in other drug-excipient systems.
