Effects of buspirone on dopaminergic supersensitivity

Abstract

The effects of buspirone treatment on dopaminergic supersensitivity induced by long-term haloperidol administration were studied; both spontaneous activity (locomotion and rearing frequencies) of rats observed in an open-field and apomorphine-induced stereotypy were used as experimental parameters. Buspirone per se (3.0 mg/kg, twice daily, for 30 days) did not produce dopaminergic supersensitivity. When buspirone was given in combination to haloperidol (2.0 mg/kg, once daily, for 30 days), it decreased the neuroleptic withdrawal symptoms as detected in open-field behavior but not in apomorphine-induced stereotypy. Although single administration of buspirone per se decreased both open-field and apomorphine-induced stereotypy behavior, buspirone single administration did not modify the acute effects of haloperidol on these two behavioral models. Taken together with previous behavioral results showing that buspirone reverses haloperidol-induced catalepsy, the present data suggest that buspirone co-administration may lead to important clinical advantages concerning different extrapyramidal side effects of neuroleptic treatment.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
