METHODS: A single oral dose 600 mg of 2 valaciclovir hydrochloride tablets was given to 18 healthy volunteers in an open randomized crossover study. The concentration of acyclovir in plasma was determined by HPLC at different time points within 14 h following administration. The pharmacokinetic parameters were calculated by BAPP 2.0 software and the bioequivalence was evaluated by two onesided t test and 90%confidence intervals.

Methods: Cinnarizine with domperidone, promethazine with ephedrine, dimenhydrinate plus amfetamine with ginger and phecynonate hydrochloride were chosen by reviewing journal articles. The placebo was lactose. Coriolis acceleration tolerance was used to evaluate the efficacy of drugs. The incidences of symptoms and signs, and the neurobehavioral evaluation system were used to evaluate side effects and the effect on performance respectively.

通过文献资料分析，选取脑益嗪和多潘立酮、异丙嗪和麻黄素、茶苯海明与苯丙胺和生姜联合用药，以及盐酸苯环壬脂等4组药物，以乳糖为安慰剂，用Coriolis加速度耐力评价药效，用副作用症状、体征发生率评价副作用表现，用神经行为评价系统测试副作用对工作能力的影响。

The hydrochloride salt can be prepared by dissolving the oil in 10x the volume of diethyl ether and gassing the solution with dry HCl gas until no more precipitate forms.

至于盐酸盐能这样来制备：把上述液体溶解在10倍体积的乙醚中，通入干燥的盐酸气体，直到液体的沉淀不再增加为止。

METHODS: After a single ip dose of trans-T hydrochloride or Ml, the rats were killed by decapitation. A high performance capillary electrophoresis method was used to determine the concentrations of enantiomers of trans-T and Ml in the serum and different brain tissues, including cerebrospinal fluid, cerebral cortex, corpus striatum, hypothalamus, cerebellum, and medulla oblongata.
