Neurotoxicological profile of actoprotector
bromantane was studied on rats using S. Irwin's protocol of multi-test observation. The
drug in doses of 30-300 mg/kg stimulated and in doses of 600-9,600 mg/kg suppressed behavioral activity. Spontaneous motor activity increased after single treatment with
bromantane in doses of 30-300 mg/kg, did not change
after treatment in doses of 600 mg/kg, and was inhibited
after treatment in doses above 600 mg/kg. In doses of 300-600 mg/kg the
drug reduced
pain sensitivity threshold and in doses above 600 mg/kg elevated the pain threshold and tactile sensitivity and reaction to knock.
Bromantane induced
mydriasis in all studied doses; in doses above 10 g/kg the preparation induced
blepharoptosis. In doses above 5 g/kg
bromantane slightly increased respiration rate and depth (Kussmaul-like respiration). In some animals
bromantane in high doses induced regurgitation,
diarrhea, and
polyuria. Rectal temperature decreased by 0.5-1 degrees C after virtually all doses. Behavioral effects of
bromantane in doses of 30 and 600 mg/kg were associated with stimulation of the central
dopamine and suppression of
muscarinic and nicotinic
cholinergic structures, n-
cholinolytic effects of
bromantane was more pronounced at a dose of 30 mg/kg than at a dose of 600 mg/kg.
