摘要：
Purpose. The dependence of the molecular mobility of lyophilized formulations on pharmaceutical polymer excipients was studied. Molecular mobility as determined by NMR relaxation-based critical temperature of molecular mobility (Tmc) and glass transition temperature (Tg) is discussed in relation to the plasticizing effect of water in formulations.
