Abstract: This invention relates to the use of combinations of a sodium channel blocking compound that binds to an SSI or SS2 site of extracellular region of a sodium channel alpha subunit, and aspirin in manufacturing drugs for producing synergistically analgesic effect in mammals. Pharmaceutical compositions based upon this invention can enhance analgesic effect and reduce dosage of aspirin, therefore side effects and adverse reactions are decreased accordingly.

Abstract: A pharmaceutical analgesic composition comprising an opioid analgesic agent and a compound that binds to the SS1 or SS2 subunit of a sodium channel, such as tetrodotoxin and saxitoxin, and analogs thereof. Administration of an opioid analgesic agent and a compound that binds to the SS1 or SS2 subunit of a sodium channel, such as tetrodotoxin and saxitoxin, and analogs thereof, produces analgesia in the treatment of pain in mammals.
