Overdosage:
10 overdosage in the event of accidental ingestion or toxic overdosage with atropine sulfate ophthalmic solution supportive care may include a short acting barbiturate or diazepam as needed to control marked excitement and convulsions. large doses for sedation should be avoided because central depressant action may coincide with the depression occurring late in atropine poisoning. central stimulants are not recommended. physostigmine, given by slow intravenous injection of 1 to 4 mg (0.5 to 1 mg in pediatric populations), rapidly abolishes delirium and coma caused by large doses of atropine. since physostigmine is rapidly destroyed, the patient may again lapse into coma after one to two hours, and repeated doses may be required. artificial respiration with oxygen may be necessary. cooling measures may be needed to help to reduce fever, especially in pediatric populations. the fatal pediatric and adult doses of atropine are not known.

Clinical Pharmacology:
12 clinical pharmacology 12.1 mechanism of action atropine acts as a competitive antagonist of the parasympathetic (and sympathetic) acetylcholine muscarinic receptors. topical atropine on the eye induces mydriasis by inhibiting contraction of the circular pupillary sphincter muscle normally stimulated by acetylcholine. this inhibition allows the countering radial pupillary dilator muscle to contract which results in dilation of the pupil. additionally, atropine induces cycloplegia by paralysis of the ciliary muscle which controls accommodation while viewing objects. 12.2 pharmacodynamics the onset of action after administration of isopto atropine 1% generally occurs in minutes with maximal effect seen in hours and the effect can last multiple days [see clinical studies (14) ]. 12.3 pharmacokinetics in a study of healthy subjects, after topical ocular administration of 30 µl of atropine sulfate ophthalmic solution, 1%, the mean (± sd) systemic bioavailability of l-hyoscyamine was
