Toxicity | A belladonna plant alkaloid that exerts its pharmacodynamic effects by blocking muscarinic acetylcholine receptor sites. The s.c. LD50 of scopolamine hydrobromide in mice is 3.8 g/kg. Scopolamine crosses the blood brain barrier, and its antimuscarinic effects include, in therapeutic doses, drowsiness, euphoria, amnesia, fatigue, loss of REM sleep and, at higher doses, restlessness or even delirium. Scopolamine can be used to treat motion sickness and parkinsonian tremor. The effects of scopolamine may be greater in the CNS than atropine, and it may be a better antidote for organophosphate intoxication. |
