HIDE SMILES / InChI
Benzhydrocodone is a prodrug of hydrocodone. Benzhydrocodone is formed by covalently bonding hydrocodone to benzoic acid. Benzhydrocodone itself is not pharmacologically active, but must be metabolized to hydrocodone by enzymes in the intestinal tract to optimally deliver its pharmacologic effects. Hydrocodone is a full agonist of the opioid receptors with a higher affinity for the mu-opioid receptor. Upon binding, hydrocodone produces an analgesic effect with no ceiling. APADAZ a combination of benzhydrocodone and acetaminophen is FDA approved and indicated for the short-term (no more than 14 days) management of acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. APADAZ, even when taken as recommended, can result in addiction, abuse, and misuse, which can lead to overdose and death.
