Common NamePhenyltoloxamine
DescriptionPhenyltoloxamine, also known as phenoxadrin or antin, belongs to the class of organic compounds known as diphenylmethanes. Diphenylmethanes are compounds containing a diphenylmethane moiety, which consists of a methane wherein two hydrogen atoms are replaced by two phenyl groups. Phenyltoloxamine is a drug. Phenyltoloxamine is a very strong basic compound (based on its pKa). In humans, phenyltoloxamine is involved in phenyltoloxamine h1-antihistamine action. Though it is rare in several western countries, phenyltoloxamine is widely used on the global scale, particularly in the developing world. When used in preparations with acetaminophen it is generally over the counter. Phenyltoloxamine is widely used in preparations as an enhancing agent for some analgesics and antitussives (acetaminophen, dihydrocodeine, codeine, hydrocodone). It is also used to discourage abuse in certain opiate analgesics due to its unpleasant side effects at high doses. Phenyltoloxamine has analgesic and anti-spasmodic properties of its own and is used in combination with paracetamol, aspirin and other salicylates and other drugs in proprietary preparations available over the counter for backache, muscle strains and similar conditions. Some preparations contain opiates such as codeine or hydrocodone and are controlled. Common adverse effects are those associated with most anticholinergics, with effects being more pronounced in children and the elderly. Phenyltoloxamine is an antihistamine with sedative and analgesic effects. Phenyltoloxamine, like diphenhydramine and doxylamine, is an effective non-narcotic anti-tussive on its own but tends to be effective only for productive coughs as the anticholinergic action will exacerbate dry, unproductive coughs, so it is often combined with dextromethorphan, codeine, ethylmorphine, dihydrocodeine, or hydrocodone in cough suppressants both over the counter and prescription. It was taken off the market but is available OTC again in the US by some pharmaceutical companies.
