Neurotoxicology. 2009 Nov;30 Suppl 1:S17-31. Epub 2009 Sep 18.

Four of six alpha-cyano pyrethroids (lambda-cyfluthrin, cypermethrin, deltamethrin and fenpropathrin) reduced open chloride channel probability.

This study investigated the effects of on I (AB) of four pyrethroid agents tefluthrin (a selective activator of this current), tetramethrin, fenpropathrin and alpha-cypermethrin in addition to other well known chloride channel modulators (chlorotoxin, gadolinium and picrotoxin).

It therefore appears clear that in some combinations the type I and type II pyrethroids can compete and may bind to the same chloride channel target site.
For single dosing at 10 microM, bioallethrin, beta-cyfluthrin, cypermethrin, deltamethrin, and fenpropathrin were all found to significantly decrease open channel probability (p < 0.05).
