Drug Names(s): combination: tramadol and low-dose naltrexone

Description: PTI-601 is a combination of tramadol and low-dose naltrexone.

Tramadol is a centrally acting analgesic. Although its mode of action is not completely understood, several complementary mechanisms appear applicable: mild agonism of parent and M1 metabolite to µ-opioid receptors, weak inhibition of reuptake of norepinephrine and serotonin, and modulation of the GABAergic system.

Naltrexone is an opioid antagonist. The company believes that a very low-dose of an opioidantagonist can enhance pain relief, reduce adverse side-effects and attenuate the development of tolerance and addiction.
