Provings and Poisonings
See also Hyoscyaminum, III, 2. -1. According to Charpentier(Ann. de Theridion, xxiv, 21) D.dilates the pupils more rapidly than atropine, but the effect is less prolonged, and is never followed by contraction. A quantity in solution exceeding 4 milligram. cannot be instilled into the eye without causing redness and pain. By the stomach a larger dose than gr.1/10 is unsafe, but its toxical effects are less intense and lasting than those of atropine. A congested state of the skin may exist, but not the scarlatinoid eruption. Headache is more severe, with neuralgic paroxysms; the circulation is quickened; there is an uneasy sensation about the praecordia, with feeling a faintness; restless and noisy delirium occurs, with hallucinations, erection also and emissions, but no disorder of the bowels.(STILLE, op.cit.).
