Nyob rau hauv xyoo tas los no, kev tshawb fawb txog tshuaj los txhim kho kev txawj ntse, thiab txhawb kev kawm thiab kev nco tau ua rau muaj kev txaus siab heev. Piracetam yog thawj zaug uas tsis yog-pseudo-lub hlwb stimulant uas tsis cuam tshuam rau tus cwj pwm. Nws xaiv ua rau lub paj hlwb cortex, dilates cerebral hlab ntsha, thiab yog siv los kho lub hlwb raug mob, cerebral ischemia, thiab mob cerebral insufficiency. Tib lub sijhawm, nws tau pom tias cov tshuaj tuaj yeem txhim kho kev kawm thiab kev nco. Tsiaj thwmsim qhia tau hais tias nws homolog, Etriraeetam, kuj tseem txhawb kev kawm, txhim khu kev nco thiab txhawb kev nco rov qab.
Nyob rau hauv xyoo tas los no, ib qho tshiab monoamine compound los txhawb kev kawm thiab kev nco, nws cov tshuaj npe yog {{0}} benzoic acid methyl acetate hydrochloride (PRL-8-53), muaj peb zaug cov nyhuv ntawm millet alkali rau kev kawm thiab kev nco, thiab spasm induced los ntawm 20mg Baci: tuaj yeem tiv thaiv los ntawm 0.075.0.lmg ntawm cov khoom no.
Raws li ntau npaum li cas thiab ntau npaum li cas,PRL-8-53 hmoovpom antagonistic lossis agonistic cuam tshuam ntawm cholinergic thiab dopaminergic. Tsis tas li ntawd, Nws muaj toxicity tsawg thiab tsis muaj kev phiv tshwm sim. Txawm li cas los xij, kev mob toxicity tsis tau tshaj tawm, thiab nws yooj yim hauv cov qauv thiab yooj yim rau kev sib txuas.
