Most frequent reasons for using anticholinergic agents for preoperative medication:

Do most currently used inhaled or injected anesthetic stimulate significant upper airway secretions?

Anesthetic agent which may, because it causes excessive secretions, require the use of an antisialagogue.

More potent antisialagogue: scopolamine or atropine?

More useful when antisialagogue effects and sedation are both required as part of preoperative preparations: atropine or scopolamine?

More potent as an antisialagogue: glycopyrrolate (Robinul) or atropine?

Within the preoperative timeframe, when should an anticholinergic agent be administered?

Antisialagogue drug which is a quaternary amine (always positively charged, independent of pH)

Most reasonable Route of Administration of anticholinergic drugs used for the purpose of blocking/attenuating reflex bradycardia:

Anticholinergic drug most likely to induce central nervous system toxicity, in particular central anticholinergic syndrome:

Antidote for CNS toxicity due to muscarinic cholinergic receptor blockade, secondary to scopolamine overdosage, for example manifested as central anticholinergic syndrome:

Drug Classification of physostigmine (Antilirium)

Ineffective anticholinesterases for management of central anticholinergic syndrome
