7-Hydroxymitragynine (7-OH) is a terpenoid indole alkaloid from the plant Mitragyna speciosa, commonly known as kratom. [2] It was first described in 1994 [3] and is a human metabolite metabolized from mitragynine present in the Mitragyna speciosa. 7-OH binds to opioid receptors like mitragynine, but research suggests that 7-OH binds with greater efficacy.
The solubility of mitragynine from kratom in neutral-pH and alkaline water is very low (0.0187 mg/ml at pH 9). [20] The solubility of mitragynine in acidic water is higher (3.5 mg/ml at pH 4), however, this alkaloid can become unstable, so certain products, such as low-pH beverages, have a very short shelf life.

Mitragynine pseudoindoxyl is a rearrangement product of 7-hydroxymitragynine, an active metabolite of mitragynine. [ 1 ] Mitragynine pseudoindoxyl can be produced in the blood as a metabolite of 7-hydroxymitragynine.
NAD+ supplements, IV drips, and injections have gained a lot of traction on social media due to their supposed anti-aging benefits. Here, doctors reveals the truth behind the trend.
The drug, suzetrigine, received the FDA's official stamp of approval Thursday to be sold as a 50-milligram prescription pill taken every 12 hours, according to a press release.

Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
