ABSTRACT
AIM To study the pharmacokinetics of arbidol capsule in Chinese healthy volunteers.METHODS A single oral dose of arbidol capsule 200 mg was given to 20 healthy volunteers respectively.Plasma samples were prepared based on a simple liquid-liquid extraction.The extracted samples were analyzed by HPLC equipped with UV detection.Pharmacokinetic parameters were calculated by 3P87 software. RESULTS The main pharmacokinetic parameters of arbidol were as follows:c(max)(418±s 241)μg·L-1,t(max)(1.3±1.2)h,t(1/2α)(1.9±2.3)h,t1/2β(14±5),hAU0-t(2 633±1 071)μg·L-1,Vc/F(0.7±0.6)L,CL(0.08±0.03)L·h-1,CONLUSION The pharmacokinetics of arbidol capsule in human body accord with two-compartmetn open model.The study will offer the pharmacokinetic parameters for the clinical application of arbidol.
ABSTRACT
OBJECTIVE:To provide reference for the improvement of Metaanalysis. METHODS:13 repots about Meta-analysis of randomized controlled trials(RCTs)on antivirus traditional Chinese medicine(TCM)injections for respiratory tract infections were collected and analyzed. Their qualities were evaluated using QUOROM statement,CONSORT statement,Jadad scale and the quality evaluation method for Metaanalysis posed by Sacks,etc. Disagreements were resolved by consensus. RESULTS:The obtained average mark of 13 studies was(64?10.13)with the highest mark of 84 and the lowest of 52. Quality evaluations of reports were conducted from 5 aspects including 25 items. 5 aspects were all considered in 13 studies. 60% of the 25 items were in- volved in 13 reports at least and 88% at most. CONCLUSION:Meta- analysis methods are improved significantly in China. It should be still standardized to make sure correctness and reliability of results of meta-analysis. Meta-analysis method should be stan-dardized to obtain correct and reliable results.
ABSTRACT
OBJECTIVE:To study the stability of Urapidil injection separately mixing with KCl injection,potassium mag?nesium-L-aspartate injection,NaHCO 3 injection,vitamine C injection and lidocaine injection in10%glucose injec?tion.METHODS:Ultraviolet spectrophotometry was used for detecting the changes of absorbance,absorption curve,and pH at15℃～25℃within0～8hours,and the external appearance and changes under light microscope were observed.RESULTS:There were no evident changes in absorbance,absorption curve,external appearance,microscopic findings and pH.CONCLUSION:Urapidil injection is stable in mixing with above-mentioned5drugs in10%glucose solution.
