Chemically scopolamine is close to atropine: it is an ester of scopine and tropic acid. Close to atropine on the effect on peripheral cholinoreactive systems. Like atropine causes pupillary dilatation, paralysis of accommodation, increased heart rate, relaxation of smooth muscles, a decrease in the secretion of digestive and sweat glands.
It also has a central holinolitic effect. Usually causes a sedative effect: reduces motor activity, can have a hypnotic effect. A characteristic property of scopolamine is the amnesia caused by it.
Scopolamine is sometimes used in psychiatric practice as a sedative, in neurological practice - for the treatment of parkinsonism, in surgical practice, along with analgesics (morphine, promedol) - for preparation for anesthesia, sometimes as an antiemetic and sedative in sea and air sickness (more often for this Goals are prescribed tablets "Aeron"), as well as with irites, iridocyclitis and with a diagnostic purpose for dilatation of the pupil instead of atropine.
The contraindications are the same as when taking atropine. It is necessary to take into account a very wide difference in individual sensitivity to scopolamine: relatively often the usual doses cause not soothing, but excitement, hallucinations and other side effects.
