Clin Ther. 2008. Bioequivalence and pharmacokinetic comparison of a single 200-mg dose of meclofenoxate hydrochloride capsule and tablet formulations in healthy Chinese adult male volunteers: a randomized sequence, open-label, two-period crossover study.Zou JJ1, Ji HJ, Wu DW, Yao J, Hu Q, Xiao DW, Wang GJ. Meclofenoxate hydrochloride is a psychostimulant in the nootropic agent group available in capsule and tablet formulations approved for traumatic cataphora, alcoholic poisoning, anoxia neonatorum, and children's enuresis in China. Although these 2 generic formulations are marketed in China, information regarding their pharmacokinetics and bioequivalence in humans has not been published. In this small study in healthy Chinese adult male volunteers, a single 200-mg dose of the capsule formulation was found to be bioequivalent to a single 200-mg dose of the tablet formulation based on the US FDA's regulatory definition (rate and extent of absorption). Both formulations were well tolerated.
Eksp Klin Farmakol. 2008. [Effects of piracetam and meclofenoxate on the brain NMDA and nicotinic receptors in mice with different exploratory efficacy in the cross maze test. Kovalev GI, Firstova IuIu, Salimov RM.AbstractA population of outbred mice of the ICR strain was divided into two subpopulations according to their high (EH mice) or low (EL mice) exploratory efficacy in the closed cross maze test. In addition, the EH and EL mice differed in the number of binding sites of (i) [G-3H]-MK-801 with NMDA receptors from hippocampus and (ii) [G-3H]-nicotine with nicotine cholinoreceptors (nACh) from neocortex. A subchronic administration of the cognition enhancer piracetam (200 mg/kg, once per day for 5 days) increased by 70% the number of binding sites of NMDA receptors in the EL mice. At the same time, this treatment decreased the density of neocortical nACh receptors in both EL and EH mice (by 55% and 40%, respectively). A subchronic administration of the cognition enhancer and anti-oxidant meclofenoxate (100 mg/kg, once per day for 5 days) also decreased the density of neocortical nACh receptors in both EL and EH mice (by 48% and 20%, respectively). However, meclofenoxate also increased by 41% the number of binding sites of NMDA receptors in the EH mice.
