Using the patch-clamp method in isolated rat cardiac myocytes, indicated that Spiradoline mesylate (15 to 500 μM) produces its antiarrythmic effect via blockade of sodium channels (and at the higher doses also of potassium currents) in myocardial tissue. Thus, Spiradoline mesylate reduces the peak sodium current, increased the decay rate of the transient outward potassium current, and reduced the sustained plateau potassium amplitude.

Spiradoline mesylate (U-62066; 0.1-0.4 mg/kg; subcutaneous injection; once; Sprague-Dawley rats) treatment dose-dependently reduces social behaviors in non-stressed adults, producing social avoidance at the highest dose tested, while younger animals displays reduced sensitivity to this socially suppressing effect of Spiradoline mesylate. In stressed animals, the socially suppressing effects of the Spiradoline mesylate are blunted at all ages, with juveniles and adolescents exhibiting increased social preference in response to certain doses of U-62066. Animal Model:Juvenile, adolescent and adult Sprague-Dawley male and female rats exposured to repeated restraint Dosage:0.1 mg/kg, 0.2 mg/kg, 0.3 mg/kg, and 0.4?mg/kg Administration:Subcutaneous injection; once Result:Dose-dependently reduced social behaviors in non-stressed adults, producing social avoidance at the highest dose tested.
