摘要：Background:To investigate the toxicity of N-n-butyl haloperidol iodide(F2),a quaternary ammonium salt derivative of haloperidol,in mice for potential therapeutic purposes.
Methods:The acute median lethal dose(LD50)of F2 was determined using the Bliss method following intravenous administration in mice.Routine surface electrocar-diograms(ECGs)and arterial blood pressures(aBPs)were recorded under general anesthesia in untreated and pharmacologically vagotomized mice injected with F2.Sublethal doses of F2 were tested for their effects on aBP,heart rate,and biochemi-cal parameters such as lactate dehydrogenase(LDH),blood urea nitrogen(BUN),and serum lactate levels.Histopathological changes in the heart,lungs,liver,and kidneys were evaluated after F2 administration.
Results:The acute LD50 of F2 was determined to be 5.11mg/kg.A 10mg/kg dose of F2 caused severe hypotension,second-degree atrioventricular block,progressive prolongation of Pmurr intervals,and death due to cardiac asystole.Similar ECG and aBP changes were observed in atropine-pretreated mice,indicating that cholinergic effects do not play a major role in F2-induced toxicity.Sublethal doses of F2(1.2 and 2.4mg/kg)caused dose-dependent decreases in aBP and increases in heart rate.F2 induced significant,dose-dependent increases in LDH,BUN,and serum lactate levels.Histopathological analysis revealed acute lung lesions at 10mg/kg,with no significant changes observed in the heart,liver,or kidneys.
Conclusion:Acute intravenous injection of F2 exhibits dose-dependent cardiopul-monary toxicity,characterized by severe hypotension,arrhythmias,and biochemical changes.These findings highlight the potential risks of F2 and the need for further evaluation of its safety profile for therapeutic use.
