ABSTRACT
Oral administration, as the most common way of administration of Chinese materia medica (CMM), has the characteristics of high safety, low toxicity, economical convenience and so on. However, the problem of poor absorption and low bioavailability exists in the process of oral administration of CMM ingredients. In order to elucidate the correlation between in vivo and in vitro drug bioavailability, drugs are classified into four categories according to their solubility and membrane permeability by the biopharmaceutics classification system (BCS). Except for BCSI, which can be effectively and stably absorbed, the other three types have different degrees of low oral bioavailability. The current theory about the low bioavailability of CMM ingredients is not clear. What causes the bioavailability of active ingredients of CMM to be unsatisfactory? How does the effective absorption of CMM ingredients work? Based on the above problems, this paper briefly reviews the mechanism of the poorly absorbable oral CMM from the aspects of superposition, synergy, intestinal flora, genetic synergistic death and intestinal transporter to reveal the effectiveness of CMM ingredients. The mechanism provides new ideas for interpreting the essence of the efficacy of CMM.
