Hydrocodone bitartrate

Overview

Basic Info

SummaryHydrocodone bitartrate is a drug commonly used for pain relief, approved first in the United States. The drug works by binding to opioid receptors in the brain, acting as a mu/kappa/delta agonist. Its chemical name is 4,5(alpha)-epoxy-3-methoxy-17-methylmorphinan-6-one tartrate (1:1) hydrate (2:5) or morphinan-6-one, 4,5-epoxy-3-methoxy-17-methyl-, (5 alpha)-, [R (R*, R*)]-2,3-dihydroxybutanedioate (1:1),hydrate (2:5). Hydrocodone bitartrate is widely used in the U.S. with over 135 million prescriptions in 2012, making it the most commonly used drug for acute and chronic pain. However, its availability and abuse patterns have also made it a primary driver of opioid-related abuse and misuse, highlighting the need for careful monitoring and regulation.
