Like brevetoxins, they act on site 5 of the alpha subunit of the sodium channel receptor to increase excitability and prolong refractory periods of sensory and motor nerves. Opening a sodium channel causes depolarization, which could sequentially cause paralysis, heart contraction, and changing the senses of heat and cold. The major symptoms will develop within 1-3 hours of toxin ingestion: vomiting, diarrhea, numbness of extremities, mouth and lips, reversal of hot and cold sensation, muscle and joint aches.
