Pyrantel pamoate (Pyrantel Embonate)是一种广谱驱虫剂,用于治疗一些寄生虫感染。
体外研究
Pyrantel induces
Ascaris suum
muscle contraction, with a pEC
50
of 7.24.
Pyrantel produces spastic paralysis of the nematode by selectively gating acetylcholine receptor ion-channels on nerve and muscle.
Pyrantel (72 h) inhibits the survival of
Ancylostoma ceylanicum
,
Necator americanus
and
Trichuris muris
on the third-stage larvae (IC
50
s=90.9, 2.0, and 95.5 µg/mL, respectively) and adult worms (IC
50
s=>100, 7.6, and 34.1 µg/mL, respectively).
体内研究
Pyrantel (10 mg/kg; a single p.o.) reduces the worms in A. ceylanicum -infected hamsters, with the worm burden reduction of 87.2% and worm expulsion rate of 63.4%.
