glycyrrhizic acid/dental caries

Traditional vaginal preparations reside in the vaginal cavity for relatively a short period of time, requiring multiple doses in order to attain the desired therapeutic effect. Therefore, mucoadhesive systems appear to be appropriate to prolong the residence time in the vaginal cavity. In the

OBJECTIVE The aim was to synthesize molecularly imprinted polymers (MIPs) with high recognition properties towards glycyrrhizic acid and to evaluate the performance of these materials to act as base excipients in glycyrrhizic acid sustained release in gastrointestinal simulating fluids. METHODS MIPs

In this work, a new molecularly imprinted solid phase extraction protocol was developed for the selective extraction and purification of glycyrrhizic acid from liquorice roots in aqueous media. The molecularly imprinted polymers (MIPs) for glycyrrhizic acid were prepared by using

In vitro release tests and in vivo absorption measurements of oral cavity dosage forms of isosorbide dinitrate (ISDN) prepared from mixed polymer film systems were conducted. Hydroxypropylcellulose (HPC) and hydroxypropylmethylcellulose phthalate (HPMCP) were used to make the films, and the tests
