Application

Scopolamine hydrobromide has been used as a muscarinic receptor antagonist:
  • to reverse the cardiac effects of physostigmine in rabbit heart
  • to study its effect on acoustic startle reflex (gap-PPI){148)
  • to study it′s in vitro antiviral, antibacterial, and antifungal activities and cytotoxicity
  • to study its effect on conditioning of lever pressing

Biochem/physiol Actions

Competitive nonselective muscarinic acetylcholine antagonist. Scopolamine-induced amnesia in laboratory animals is a commonly-used model of memory deficit.
