Metabolic studies of a new non-antimonial antischistosome agent-Nithiocyamine were carried out on animals and reviewed together with some human results. In rabbits, the blood concentration reached a peak at the 4th hour after oral administration, then fell gradually, pharmacokinetic parameters were assessed by the two compartment open model where three biological half-lives t_(1/2)ka, t_(1/2)α and t_(1/2)β were shown to be 0.855, 0.924 and 105.8 hours respectively; and the three rate constants k_(el), k_(21),...

Metabolic studies of a new non-antimonial antischistosome agent-Nithiocyamine were carried out on animals and reviewed together with some human results. In rabbits, the blood concentration reached a peak at the 4th hour after oral administration, then fell gradually, pharmacokinetic parameters were assessed by the two compartment open model where three biological half-lives t_(1/2)ka, t_(1/2)α and t_(1/2)β were shown to be 0.855, 0.924 and 105.8 hours respectively; and the three rate constants k_(el), k_(21), and k_(12), 0.0127, 0.398 and 0.356 hour~(-1) respectively. The apparent volume of distribution (V_f)was calculated as 0.934L/kg.Nithiocyamine distributed widely in many tissues after absorption. In rats, at the 4th hour after oral administration, the drug occurred in the following tissues in concentrations of ascending order: the liver kidney, spleen, lung, muscle, heart, brain and blood. In infected rabbits, the schistosomes took up more drug than tissues of the host animal, and female schistosomes more than the male. Nithiocyamine was excreted only slowly through the urine and bile. Urinary excretion in human usually lasted more than 3 days after a single oral administration, and lasted more than 19 days after three consecutive dosages.The metabolites occurred in urine were extracted and separated by TLC, Chemical methods UV an. HPLC, examination revealed that it was the NCS group first reduced into amino, and then conjugated with glucuronic acid to form a N-glycoside.. This metabolic change is one of its biotransformation pathways.

Nine healthy volunteers received a single dose of 7.5mg/kg of Amikacin intramuscularly, Amikacin was rapidly absorbed from injection site. A peak serum level after 1 hr averaged 23.59/μg/nl, and declined to 12.77μg/ml 3 hrs later. 12 hrs after the administration of Amikacin in serum was 0.78/μg/ml. Pharmacokinetical parameters of Amikacin were determined by a least-squares. Analysed parameters were based on a two-compartment, open-system kinetic model. The halflife time of Amikacin was 2.48 hrs. Apparent volumes of distribution averaged 22.6% of body weight, and the mean rate of renal clearance was 72.56ml/min. Of the administered dose, 92.28% was recovered from the urine in 24 hours.

九名健康人单次肌注丁胺卡那霉素7.5mg/kg,1小时后的高峰血浓度为23.58μg/ml,3小时的血清浓度为高峰血浓度的1/2(12.77μg/ml),12小时浓度降至0.78/μg/ml。药物主要从肾脏排出,24小时内排出给药量的92.28%,100μg/ml以上的尿浓度可维持12小时,最高可达1451μg/ml。血清浓度动力学按两室开放式模型分析,表观分布容积Vd13.56升,肾清除率Q72.56ml/min。根据动力学参数计算出的不同时间的血浓度与实测值非常接近。五名病毒性肝炎患者肌注相同剂量的丁胺卡那霉素后,血浓度与正常人的水平相接近。1例老年慢性病毒性肝炎肝硬变病人,肌注丁胺卡那霉崇7.5mg/kg后,血浓度明显高于正常人,血清消除半衰期为6.3小时,提示该类病人体内动力学过程有所改变。
