Phenyltoloxamine
From Wikipedia, the free encyclopedia
Phenyltoloxamine is an antihistamine with sedative and analgesic effects. It is a member of the ethanolamine class of antihistaminergic agents and a potent anticholinergic, with 55 per cent of the anti-muscarinic potency of atropine.
[edit] Common use
Phenyltoloxamine is widely used in preparations as an enhancing agent for some analgesics and antitussives (acetaminophen, codeine, hydrocodone). It is widely used in certain parts of the world as cough suppressant usually with codeine.
It is also used to discourage abuse in certain opiate analgesics due its unpleasant side effects at high doses. While therapeutic doses of phenyltoloxamine can generate mild euphoria as can many of its chemical relatives, much higher doses have a side effect profile similar to that of atropine, which is also used in this fashion for tablets of diphenoxylate and morphine for oral administration.
[edit] Adverse effects
Common adverse effects are those associated with most anticholinergics, effects are more pronounced in children and the elderly.
