 Use of Difenidol


Diphenidol is an orally active antiemetic. Diphenidol reduces abnormal neuropathic pain and TNF-α overexpression in rats following chronic compression injury. Diphenidol also has local anaesthetic activity and inhibits sodium currents. Diphenidol can be used in studies of meniere′s disease, anti-vertigo, antiemetic and analgesia[1][2].

In Vitro Diphenidol (0.1-100 µM) blocks Na+ currents with an IC50 of 0.77 µM and a Hill coefficient of 1.15 in N2A cells[1].
In Vivo Diphenidol (0.77 mg/rat; intrathecal injection; single) blocks motor function, proprioception, and nociception in rats[1]. Diphenidol (0.62, 3.09 mg/kg; i.p.; single daily for 7 days) effectively reverses or completely blocks CCI-evoked mechanical allodynia in rats[2]. Animal Model: Male SpragueeDawley rats (275-325 g)[1]. Dosage: 0.77 mg/rat (2.50 µmol/rat) Administration: Intrathecal injection; single. Result: Caused 100% of blockades in motor function, proprioception, and nociception with durations of action of about 51, 77, and 123 min, respectively. Animal Model: Male adult Sprague-Dawley rats (200-250 g; CCI rat model)[2]. Dosage: 0.62, 3.09 mg/kg (2, 10 µmol/kg) Administration: Intraperitoneal injection; single daily for 7 days. Result: Blocked the CCI-induced low mechanical withdrawal threshold at 1 h after administration. Reduced the level of TNF-α on day 7 and alleviated neuropathic tactile allodynia following CCI in rats.
