oral drugs for IBS) for motion sickness, but there currently is no oral version of scopolamine (hyoscine).
Oral versions of scopolamine would seem equally likely to work as patches (e.g. meclizine, hyocyamine, and many other antihistamines), but scopolamine has no central antihistamine component (which is associated with sleepiness and weight gain). scopolamine) is better than any other ACH antagonist (e.g. There is no reason to believe that any one nonselective ACH antagonist (e.g. There are also some reports of scopolamine inducing migraine, as well as a withdrawall syndrome. Diphenidol (Vontrol), is also an anticholinergic, although little used in the US. Scopolamine and atropineĪre nonspecific muscarinic receptor antagonists (Barton et al, 1994 Soto et al, 2013).

Unlike antihistamines which will be discussed subsequently, pure anticholinergics are Important in treating vertigo, since anticholinergic drugs that do not cross theīlood-brain barrier are ineffective in controlling motion sickness (Takeda et al, 1989).

Hyoscine, or scopolamine, is mainly used in the patch form to prevent motion sickness.Īgents with central anticholinergic effects are most Hyoscyamine, which is the L-isomer of atropine, is a common ingrediant in antispasmodic treatments for IBS. Thus it makes some sense to use prescription anticholinergics rather than OTC mixed drugs (such as meclizine). The antihistamine component has side effects of sleepiness and long term weight gain (see below). Examples are meclizine, dimenhydrinate, and diphenhydramine. The mixed antihistamine/anticholinergic drugs are often available OTC, or "over the counter".
