Biological Activity
Homatropine (20 μM) alone produces a dose ratio of 259 in atrium from guinea-pigs, and produces a dose ratio of only 95.0 when combined with Hexamethonium Bromide (HY-B0569) in atrium from guinea-pigs[1].
Homatropine has affinities for muscarinic receptors in stomach (pA2 = 7.13) and for those in atria mediating force (pA2 = 7.21) and rate (pA2 = 7.07) responses[2].

Animal Model:Male albino rats[3]
-
Dosage:9 mm x 5 mm conical suppository
-
Administration:By suppository
-
Result:Blocked cardiovascular responses to vagal stimulation and acetylcholine; 10-20 min after insertion of the suppository the effects of vagal stimulation over a range of 2-16 Hz, 5 V, on pulse rate was virtually abolished and remained unchanged at 45-60 min.
