Interaction Details
Sumatriptan Succinate is classified as belonging to the following category: Serotonergic Drugs
Theoretically, taking kratom in combination with serotonergic drugs may increase levels of serotonin, increasing the risk of serotonin syndrome.
A 63-year-old male presented with possible serotonin syndrome after taking an unknown dose of kratom for up to 3 months along with serotonergic prescription medications bupropion, buspirone, desvenlafaxine, trazodone, and ziprasidone. It was hypothesized that kratom inhibited the cytochrome P450 3A4-, 2C9-, 2D6-, and 1A2-mediated metabolism of several of these serotonergic medications, consequently increasing systemic exposure to serotonin.

Kratom Overview
Kratom is a tropical tree from Southeast Asia, and its leaves are known for their potent effects. The leaves contain mitragynine and 7-hydroxymitragynine, which interact with the brain's opioid receptors, producing effects similar to opioids. Mitragynine acts as a partial agonist, providing pain relief and mood enhancement, while 7-hydroxymitragynine is even more potent, estimated to be about 10 times stronger than morphine. These compounds can stimulate opioid receptors, leading to effects such as euphoria and pain relief at lower doses, while higher doses can cause sedation and opioid-like effects. Kratom's safety and legal status are hotly debated, and it's banned or restricted in many places.
