Many of these substances possess anticholinergic activity as either a direct therapeutic effect or as an adverse effect in addition to their primary or predominant pharmacologic effect. Atropine (D,L-hyoscyamine), hyoscyamine, and scopolamine (L-hyoscine) are natural alkaloids that represent prototypical anticholinergic compounds.
