Diphenhydramine (1-300 渭M, 30 s) can block NMDA-activated membrane currents. This property can be responsible for or add to its sedative, analgesic and memory related effects[2].
Diphenhydramine (0-10 mg/kg, i.v. and p.o.) has better oral bioavailability when used in combination with Dimenhydrinate sup>[3].
Diphenhydramine (20 mg/kg, i.p.) can improve the kidney injury induced by Cisplatin (CDDP) in mice, and does not affect the anti-tumor efficacy of Cisplatin[4].
