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.
Homatropine (Equipin, Isopto Homatropine) is an anticholinergic medication that is an antagonist at muscarinic acetylcholine receptors and thus the parasympathetic nervous system. It is used in eye drops as a cycloplegic (to temporarily paralyze accommodation ), and as a mydriatic (to dilate the pupil ).
[1] [2] It contains hydrocodone, as the bitartrate, an opioid agonist; and homatropine, as the methylbromide, a muscarinic antagonist. [ 1 ] [ 2 ] It is taken by mouth . [ 1 ] [ 2 ]
Octatropine methylbromide. Octatropine methylbromide ( INN) or anisotropine methylbromide ( USAN ), trade names Valpin, Endovalpin, Lytispasm and others, [1] is a muscarinic antagonist and antispasmodic. It was introduced to the U.S. market in 1963 as an adjunct in the treatment of peptic ulcer, [2] and promoted as being more specific to the ...
A bromide ion is the negatively charged form ( Br−) of the element bromine, a member of the halogens group on the periodic table. Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [ 3]
Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide ). This volatile compound has an ether-like odor.
Homatropine methyl bromide is a separate entity. It is a quaternary ammonium salt, does not cross blood-brain barrier, has no central effect and has different indication from homatropine hydrobromide, the teriary compound. The drugbox links to the wrong picture namely the homatropine methylbromide, not the hydrobromide which is named in the ...
