Objective Polyamidoamine(PAMAM) dendrimers enhance the solubility of nicotinic acid. Methods PAMAM dendrimers of generation 1 to 6 were prepared and the effect of pH and concentration of the dendrimers on the solubility enhancement of nicotinic acid was investigated. Results The pH and concentration of the dendrimers influence the solubility enhancement of nicotinic acid. Conclusions Electrostatic interaction between the carboxyl group of the nicotinic acid and the amine groups of the dendrimers is involved.

烟酸类调脂药物的现状与展望
在诸多的调脂药物中,烟酸类调脂药物是早用于降低心血管总病死率的调脂药物之一,亦是应用历史长的调脂药物.Wang等回顾性分析美国国立急救中心5 053例患者口服调脂药物种类的构成演变,结果提示80年代临床常用的调脂药物为树脂(Resins)和烟酸,1985年以后由于贝特类药物的面世导致烟酸和树脂的用量明显下降,自1989年后他汀类调脂药逐渐替代贝特类药物成为主要的调脂药物,但烟酸仍在调脂治疗中占有一席.
