Homatropine methylbromide (INN; also known as methylhomatropine bromide) is a quaternary ammonium salt of methylhomatropine. It is a peripherally acting anticholinergic medication that inhibits muscarinic acetylcholine receptors and thus the parasympathetic nervous system. It does not cross the blood–brain barrier. It is used to effectively relieve intestinal spasms and abdominal cramps, without producing the adverse effects of less specific anticholinergics. [1] It is used, in addition to papaverine, as a component of mild drugs that help "flush" the bile.

Contents

Certain preparations of drugs such as hydrocodone are mixed with a small, sub-therapeutic amount of homatropine methylbromide to discourage intentional overdose. [2]

Hydrocodone, also known as dihydrocodeinone, is an opioid used to treat pain and as a cough suppressant. It is taken by mouth. Typically it is dispensed as the combination acetaminophen/hydrocodone or ibuprofen/hydrocodone for pain severe enough to require an opioid and in combination with homatropine methylbromide to relieve cough. It is also available by itself in a long-acting form under the brand name Zohydro ER, among others, to treat severe pain of a prolonged duration.

Thebacon, or dihydrocodeinone enol acetate, is a semisynthetic opioid that is similar to hydrocodone and is most commonly synthesised from thebaine. Thebacon was invented in Germany in 1924, four years after the first synthesis of hydrocodone. Thebacon is a derivative of acetyldihydrocodeine, where only the 6–7 double bond is saturated. Thebacon is marketed as its hydrochloride salt under the trade name Acedicon, and as its bitartrate under Diacodin and other trade names. The hydrochloride salt has a free base conversion ratio of 0.846. Other salts used in research and other settings include thebacon's phosphate, hydrobromide, citrate, hydroiodide, and sulfate.

Codeine methylbromide (Eucodin) is the bromomethane (methylbromide) salt of codeine. Its possession is prohibited in many jurisdictions. It is considered a Schedule I controlled substance in the United States, with a DEA ACSCN of 9070 and nil annual aggregate manufacturing quota. as of 2014. As it is used in a different way than basic salts of codeine like the phosphate or hydrochloride owing to its below-mentioned dual action, it is considered to be a different drug related to codeine rather than merely a salt of it in many contexts.

<span class="mw-page-title-main">Hydrocodone/ibuprofen</span> Combination drug

Hydrocodone/ibuprofen (INNs), sold under the brand name Vicoprofen, is a fixed-dose combination analgesic medication used in short-term therapy to relieve severe pain. Vicoprofen combines the analgesic and antitussive properties of hydrocodone with the analgesic, anti-inflammatory, and antipyretic properties of ibuprofen. In contrast to hydrocodone/acetaminophen combination analgesics such as Vicodin, this hydrocodone/ibuprofen avoids some of the liver toxicity which may occur from acetaminophen, but still presents significant dangers in hydrocodone overdose, namely respiratory depression. Vicoprofen is supplied in a fixed dose combination tablet which contains hydrocodone bitartrate, USP 7.5 mg with ibuprofen, USP 200 mg. Additional strengths of generic Vicoprofen are now available, in combinations of 5 mg/200 mg and 10 mg/200 mg respectively.
