体外研究 |
Valacyclovir (Valaciclovir; VACV) uptake was concentration dependent and saturable with a Michaelis-Menten constant and maximum velocity of 1.64mM and 23.34nmol/mg protein/5 min, respectively. A very similar Km value was obtained in hPEPT1/CHO cells and in rat and rabbit tissues and Caco-2 cells, suggesting that hPEPT1 dominates the intestinal transport properties of VACV in vitro. |
体内研究 |
For treatment of a first episode of genital herpes, a large comparative trial has shown that Valacyclovir (1g twice a day) is as effective as acyclovir (200mg five times a day) when given for 10 days. For treating recurrences, two trials show that valacyclovir is as effective as acyclovir (200mg five times a day) with a treatment period of 5 days. A daily dose of 1g of valacyclovir is as effective as 2g daily. Valacyclovir can be administered once a day. The concentrations of acyclovir in serum and CSF were measured at steady state after 6days of oral treatment with 1,000mg of valacyclovir three times a day. EC50 values of PE and AC in 3T3 cells were 0.02 and 0.01ug/ml, while values in BHK cells were 0.2 and 0.03ug/ml. Treatment of infected immunosuppressed mice and FA and VA (b.i.d., 5.5days) reduced the proportion with erythema from 100% to 24% and 38%, and eliminated ear paralysis, ear lesions (vesicles, etc) and death. Virus was absent from ear and brainstem by day 6, but reappeared after discontinuation in mice treated with VA. |
