ABSTRACT
OBJECTIVE:To provide reference for the selection and management of compound drugs. METHODS:The variet-ies and frequency of compound drugs recorded in the national drug reimbursement list and drug reimbursement list supplementary varieties in provinces (regions and municipalities) were statistically analyzed,and Spearman test method was used to conduct the correlation analysis for the variety and local economic development level. RESULTS:There were totally 126 varieties of compound drugs recorded in the national drug reimbursement list,covering 19 categories. The varieties of compound drugs in class B supple-mentary drug lists of 28 provinces (regions and municipalities) ranged from 19 to 50;for the supplementary lists of compound drugs in 24 provinces(regions and municipalities),the varieties ranged from 12 to 117. Almost 50% of the compound drugs were recorded in only 1 province(region and municipality),and most compound drugs recorded 1-4 time(s)in provinces(regions and municipalities). There was no significant relationship between the varieties number of supplementary compound drugs and the per capita GDP in a province(region and municipality)(P>0.05,r=-0.180). CONCLUSIONS:The supplementary variety of com-pound drugs in a region has little relationship with the local economic development level. The work progress of recoding the com-pound drugs varies a lot,with large differences in number and high dispersion. It is necessary to clarify the definition of compound drug at a national level,develop unified management policies,standardize the selection criteria for compound drugs and guarantee the clinical medication requirements of patients.

ABSTRACT
The pharmacokinetics and tissue distributions of the novel paclitaxel microemulsion based on the L-OH lipid complex made in our laboratory were studied in this article with the commercial paclitaxel injection in cremophor as reference preparation by injected intravenously with single dose of 5 mg x kg(-1) in rats. LC-MS/MS method was used to determine the drug concentration in plasma and calculate the pharmacokinetic parameters. [3H]-paclitaxel was used to reveal the tissue distributions of different organs in 0.5 h, 3 h, 24 h and 120 h. The results indicated that the AUC of the emulsion group descended to 42.55%, with the CLz and Vz increased by 2.27 times and 3.81 times respectively. Tissue distribution results revealed that the emulsion showed a significantly increase in liver and spleen with a peak concentration up to 5 times; a slightly increase was observed in lung with no statistical differences; a significantly decrease in heart, kidney, gastrointestinal tract, bone marrow, aorta, thymus, pancreas, fat, muscle, skin, seminal vesicle, reproductive organs and brain with a drop of 40%-80%. These results indicated that paclitaxel microemulsion based on L-OH lipid complexes can remarkably reduced the blood exposure, accelerate plasma clearance rate and increase distribution volume. The fact that paclitaxel microemulsion tended to be uptake by reticuloendothelial system (RES) contributed to the target in liver, spleen and lung, and help to reduce the toxicity in blood, heart, kidney and gastrointestinal tract.
