Hydrocodone is only pharmaceutically available as an oral medication. [2] It is well-absorbed, but the oral bioavailability of hydrocodone is only approximately 25%. [4] [5] The onset of action of hydrocodone via this route is 10 to 20 minutes, with a peak effect (T max) occurring at 30 to 60 minutes, [51] and it has a duration of 4 to 8 hours. [2]
Hydrocodone diversion and recreational use have escalated due to its opioid effects. [12] In 2009 and 2010, hydrocodone was the second most frequently encountered opioid in the pharmaceutical industry.
An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...
An analgesic drug, also called simply an analgesic, antalgic, pain reliever, or painkiller, is any member of the group of drugs used for pain management.Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and ...
Codeine has greater and more predictable oral bioavailability. Codeine is not reliably metabolised into its active form, morphine, by CYP2D6 due to the considerable amount of polymorphism. Many individuals lack any appreciable metabolism to morphine and experience no therapeutic effects (although may still have nausea/vomiting or constipation).

Hydrocodone/ibuprofen , sold under the brand name Vicoprofen, is a fixed-dose combination analgesic medication used in short-term therapy to relieve severe pain. [ 3 ] [ 4 ] Vicoprofen combines the analgesic and antitussive properties of hydrocodone with the analgesic, anti-inflammatory, and antipyretic properties of ibuprofen . [ 1 ]
Benzhydrocodone (contracted from benzoate-hydrocodone) is an opioid prodrug of the morphinan class. Its chemical structure consists of hydrocodone coupled with benzoic acid . Benzhydrocodone itself is inactive and acts as a prodrug to hydrocodone upon cleavage of the benzoate portion of the molecule.
