“具有高度靶向性”可能是未来药物的特点之一。“药物靶向”就是使药物通过特定的转运或作用方式在选定部位产生药理作用。应用靶向药物可增加药物疗效和减少毒性。药物靶向的途径很多:(1)药剂学途径,如局部给药;(2)利用不同的代谢途径,如“专一性”的化学治 “Highly targeted” may be one of the hallmarks of future drugs. “Drug targeting” is to make the drug through a specific transport or mode of action in selected parts of the pharmacological effects. Targeted drugs can increase drug efficacy and reduce toxicity. There are many ways to target a drug: (1) pharmacological routes such as topical administration; (2) the use of different metabolic pathways such as “specific” chemotherapeutics
