1. The action of Arecain resembles that of Muscarine and Pilocarpine externally, internally used it contracts the pupils

2. Atropine is an antimuscarinic agent since it antagonizes the muscarine-like actions of acetylcholine and other choline esters

3. 25 The results showed that antagonist of muscarine receptor—scopolamine could retard, but not completely block epileptiform discharges induced by penicillin.

4. T., 1889) Arecaine is the active principle of the areca nut, and a powerful taenicide, and is an active poison with an action of the type of muscarine and pilocarpine

5. An adsorbent having an extremely favorable adsorptive power can be obtained by immobilizing a compound capable of binding to an antibody against $g(b)1 adrenoreceptor and/or an antibody against M2 muscarine receptor on a water-insoluble support.
