Eight healthy male subjects were divided into 2 groups and given 200mg of d-α-tocopheryl acetate oil and 400mg of d-α-tocopheryl acetate 50% emulsion powder, respectively, after breakfast. In addition, 4 healthy male subjects were given 400mg of d-α-tocopheryl acetate 50% emulsion powder under fasting conditions. Mean of the area under the curve of exogenous d-α-tocopherol level in plasma after the emulsion powder administration is equivalent to that after the oil administration. Mean peak levels after the emulsion powder administration are slightly lower than those after the oil administration. There was no absorption observed for the d-α-tocopheryl acetate emulsion powder administered group under fasting conditions. Based on the present, the emulsion powder of d-α-tocopheryl acetate which we used in this evaluation is considered as a useful preparation.

Many reports (96) on the continuous intake or dosing of coenzyme Q_<10> and the increase of blood concentration were collected, and 128 pieces of data were analyzed for every dosage form. In every dosage form, the blood concentration in the steady state increased with intake, although the degree of increase depended on the dosage form. In formulations except for the water-soluble type, as the increase of blood concentration was saturated with increasing intake, the upper limit of intake that did not cause such lowering was found for every dosage form, and a regression equation of the intake and increase of blood concentration was found. The gradient of the regression equation for every dosage form was in the order of: water-soluble type > soft gel capsules ≧ tablet > wafers. Hence, the water-soluble type showed the best increase of blood concentration with intake.
